serious or fatal injury.  

Some Important Safety Precautions for Chain Saw Users  

A.  

Do not rely exclusively upon the safety  

devices built into your saw. As a  

chainsaw user, you should take several  

steps to keep your cutting jobs free from  

accident or injury.  

6. Follow manufacturer's sharpening  

and maintenance instructions for  

the saw chain.  

A Summary of Warnings on  

kickback and other Selected  

Risks – Taken Primarily from  

ANSI B 175.1 (See also “Safety  

Precautions“ section of this  

Owner’s Manual)  

7. Only use replacement bars and  

chains specified by the  

manufacturer or the equivalent.  

1.  

With a basic understanding of  

kickback, you can reduce or  

eliminate the element of surprise.  

Sudden surprise contributes to  

accidents.  

8. Reduced kickback bars and low  

kickback chains are designed to  

reduce the risk of kickback injury.  

Ask your STIHL dealer about these  

devices.  

!

Warning!  

Kickback may occur when the nose or  

tip of the guide bar touches an object, or  

when the wood closes in and pinches  

the saw chain in the cut. Tip contact in  

some cases may cause a lightning fast  

reverse reaction, kicking the guide bar  

up and back towards the operator.  

Pinching the saw chain along the top of  

the guide bar may push the guide bar  

rapidly back towards the operator. Either  

of these reactions may cause you to lose  

control of the saw which could result in  

serious personal injury.  

2.  

Keep a good firm grip on the saw  

with both hands, the right hand on  

the rear handle, and the left hand on  

the front handle, when the engine is  

running. Use a firm grip with thumbs  

and fingers encircling the chainsaw  

handles. A firm grip will help you  

reduce kickback and maintain  

B.  

Other Safety Precautions  

!Warning!  

1. Do not operate a chainsaw with one  

hand! Serious injury to the operator,  

helpers, bystanders, or any  

control of the saw. Don't let go.  

combination of these persons may  

result from one-handed operation. A  

chainsaw is intended to be used  

with two hands.  

3.  

Make sure the area in which you are  

cutting is free from obstructions. Do  

not let the nose of the guide bar  

contact a log, branch, or any other  

obstruction that could be hit while  

you are operating the saw.  

Section 5.11 of ANSI B 175.1-2000 sets  

certain performance and design criteria  

related to chainsaw kickback. STIHLhas  

developed a color code system using  

green and yellow to help you select a  

powerhead, bar and chain combination  

that complies with the kickback  

2. Do not operate a chainsaw when  

you are fatigued.

Because a chain saw is a high-speed  

wood-cutting tool, some special safety  

precautions must be observed as with  

any other power saw to reduce the risk of  

personal injury. Careless or improper use  

may cause serious or even fatal injury.  

STIHL’s philosophy is to continually  

improve all of its products. As a result,  

engineering changes and improvements  

are made from time-to-time.  

If the operating characteristics or the  

appearance of your saw differs from  

those described in this Manual,  

please contact your STIHL dealer for  

information and assistance.

they will cut you, even if the chain is not  

moving. At full throttle, the chain speed  

can reach 45 mph (20 m/s). It is impor-  

tant that you read, fully understand  

and observe the following safety precau-  

tions and warnings. Read the Owner’s  

Manual hqthe safety instructions  

periodically.  

ꢀ

Xhꢀvtꢁ  

Minors should never be allowed to use a  

UC@ꢂPQ@S6UPS  

chainsaw. Bystanders, especially  

children, and animals should not be  

allowed in the area where a chainsaw is  

in use. Never let the saw run unattended.  

Store it in a locked place away from  

children and empty the fuel tank before  

storing for longer than a few days.  

Qu’†vphyꢂ8‚qv‡v‚  

You must be in good physical condition  

and mental health and not under the  

influence of any substance (drugs,  

alcohol) which might impair vision,  

dexterity or judgment.  

Pay special attention to the section on  

reactive forces.  

Do not lend or rent your  

chainsaw without the  

Owner‘s Manual. Be sure  

that anyone using your  

saw reads and under-  

Do not operate a chainsaw when you are  

fatigued. Be alert – If you get tired while  

operating your chainsaw, take a break.  

Tiredness may result in loss of control.  

Working with any chainsaw can be  

strenuous. If you have any condition that  

might be aggravated by strenuous work,  

check with your doctor before operating  

a chainsaw.

Reactive forces, including kickback, can  

be dangerous. Careless or improper use  

of any chainsaw may cause serious or  

fatal injury.  

stands the information contained in this  

manual.  

All safety precautions that are generally  

observed when working with an ax or a  

hand saw also apply to the operation of  

chainsaws. However, because a chain-  

saw is a high-speed, fast-cutting power  

tool, special safety precautions must be  

observed to reduce the risk of personal  

injury.  

These safety precautions and warnings  

apply to the use of all STIHL chainsaws.  

Different models may have different  

parts and controls. See the appropriate  

section of your Owner’s Manual for a  

description of the controls and function  

of the parts of your model saw.  

ꢀ

Xhꢀvtꢁ  

Prolonged use of chainsaws (or other  

machines) exposing the operator to  

vibrations may produce whitefinger  

disease (Raynaud’s phenomenon) or  

carpal tunnel syndrome. These conditions  

#

reduce the hand’s ability to feel and  

regulate temperature, produce numb-  

ness and burning sensations and may  

cause nerve and circulation damage and  

tissue necrosis.  

–

Keep the saw chain sharp and the  

saw, including the AV system, well  

maintained. A dull chain will in-  

crease cutting time, and pressing a  

dull chain through wood will in-  

crease the vibrations transmitted to  

your hands. A saw with loose com-  

ponents or with damaged or worn  

AV buffers will also tend to have  

higher vibration levels.  

Clothing must be sturdy  

and snug-fitting, but allow  

complete freedom of  

movement. Avoid loose-  

fitting jackets, scarfs,  

neckties, jewelry, flared or cuffed pants,  

unconfined long hair or anything that  

could become entangled with the saw or  

brush. Wear overalls or jeans with a  

reinforced cut retardant insert or cut  

retardant chaps.  

All factors which contribute to whitefinger  

disease are not known, but cold weather,  

smoking and diseases or physical condi-  

tions that affect blood vessels and blood  

transport, as well as high vibration levels  

and long periods of exposure to vibration  

are mentioned as factors in the develop-  

ment of whitefinger disease. In order to  

reduce the risk of whitefinger disease  

and carpal tunnel syndrome, please  

note the following:  

–

Maintain a firm grip at all times, but  

do not squeeze the handles with  

constant, excessive pressures.  

Take frequent breaks.  

Protect your hands with  

gloves when handling saw  

and saw chain.  

Heavyduty, nonslip  

gloves improve your grip  

and protect your hands.  

All the above mentioned precautions do  

not guarantee that you will not sustain  

whitefinger disease or carpal tunnel  

syndrome. Therefore, continual and  

regular users should monitor closely the  

condition of their hands and fingers.  

If any of the above symptoms appear,  

seek medical advice immediately.  

The STIHL 009 is not equipped with an  

antivibration (AV) system.  

Good footing is most  

important in chainsaw  

work. Wear sturdy boots  

with nonslip soles.  

Steel-toed safety boots  

are recommended.  

–

Many STIHL models are available  

with an anti-vibration (“AV”) system  

designed to reduce the transmission  

of vibrations created by the engine  

and cutting attachment to the  

operator’s hands. An AV system is  

recommended for those persons  

using chainsaws on a regular or  

sustained basis.  

Qꢀ‚ƒrꢀꢂ8y‚‡uvt  

To reduce the risk of injury to your eyes  

never operate a chainsaw unless  

wearing goggles or properly fitted safety  

glasses with adequate top and side  

protection complying with your national  

standard.  

ꢀ

Xhꢀvtꢁ  

To reduce the risk of injury, the operator  

should wear proper protective apparel.  

–

Wear gloves and keep your hands  

warm. Heated handles, which are  

available on most STIHL power-  

heads, are recommended for cold  

weather use.

barriers (ear plugs or ear mufflers) to  

protect your hearing. Continual and  

regular users should have their hearing  

checked regularly.  

Xhꢀvtꢁ  

Always stop the engine before putting a  

chainsaw down or carrying it. Carrying a  

chainsaw with the engine running is  

extremely dangerous.  

The chain guard (scabbard) should be  

over the chain and the guide bar, which  

should point backwards. When carrying  

your saw, the bar should be behind you.  

UC@ꢂT6X  

Accidental acceleration of the engine  

can cause the chain to rotate. During  

operation, the powerhead muffler and  

the material around it reach extremely  

high temperatures. Avoid touching the  

hot muffler, you could receive serious  

burns.

and definitions of the parts see the  

chapter on “Main Parts of Saw”.  

7’ꢂ‰ruvpyr)ꢂWhen transporting in a  

vehicle, keep chain and bar covered with  

the chain guard. Properly secure your  

saw to prevent turnover, fuel spillage  

and damage to the saw.  

ꢀ

Xhꢀvtꢁ  

Never modify a chainsaw in any way.  

Only attachments and parts supplied by  

STIHL or expressly approved by STIHL  

for use with the specific STIHL saw  

models are authorized. Although certain  

unauthorized attachments are useable  

with the STIHL powerhead, their use  

may, in fact, be extremely dangerous.

from escaping gas vapor and fumes,  

remove the fuel filler cap on the STIHL  

product carefully so as to allow any  

pressure build-up in the tank to release  

slowly. Never remove fuel filler cap while  

engine is running.  

Your STIHL chainsaw uses an oil-gaso-  

line mixture for fuel (see chapter “Fuel”  

of your Owner’s Manual).  

Before replacing any bar and chain,  

see the sections on “Specifications”,  

"Kickback" and the "ANSI B 175.1-2000  

ꢀ

chainsaw kickback standard" in this  

manual.  

Xhꢀvtꢁ  

Gasoline is an extremely flammable fuel.  

If spilled or ignited by a spark or other  

ignition source, it can cause fire and  

serious burn injury or property damage.  

Use extreme caution when handling  

gasoline or fuel mix.  

Select bare ground for fueling and move  

at least 10 feet (3 m) from fueling spot  

before starting the engine. Wipe off any  

spilled fuel before starting your saw, and  

check for leakage.  

ꢀ

Xhꢀvtꢁ  

Proper tension of the chain is extremely  

important. In order to avoid improper  

setting, the tensioning procedure must  

be followed as described in your manual.  

Always make sure the hexagonal nut(s)  

for the sprocket cover is (are) tightened  

securely after tensioning the chain.  

Never start the saw with the sprocket  

cover loose. Check chain tension once  

more after having tightened the nut(s)  

and thereafter at regular intervals (when-  

ever the saw is shut off). If the chain  

becomes loose while cutting, shut off the  

engine and then tighten. Never try to  

tighten the chain while the engine is  

running!  

ꢀXhꢀvtꢁ  

Do not smoke or bring any  

fire or flame near the fuel  

or the chainsaw. Note that  

combustible fuel vapors  

may be vented from the  

fuel system.  

Check for fuel leakage while refueling  

and during operation. If fuel or oil leakage  

is found, do not start or run the engine  

until leak is fixed and spilled fuel has  

been wiped away. Take care not to get  

fuel on your clothing. If this happens,  

change your clothing immediately.

Different models may have different fuel  

caps.  

ꢀXhꢀvtꢁ  

Fuel your chainsaw in well-ventilated  

areas, outdoors only. Always shut off the  

engine and allow it to cool before refue-  

ling. Gasoline vapor pressure may build  

up inside the gas tank of a two cycle  

engine depending on the fuel used, the  

weather conditions, and the venting  

system of the tank. In order to reduce

Be sure that the guide bar and chain are  

clear of you and all other obstructions  

and objects, including the ground. When  

the engine is started, the engine speed  

with the starting throttle lock engaged  

will be fast enough for the clutch to  

engage the sprocket and, if the chain

To reduce the risk of personal injury from  

loss of control or contact with the  

running chain, do not use a saw with  

incorrect idle adjustment. At correct idle  

speed, the chain should not rotate. For  

directions to adjust idle speed, see the  

appropriate section of your Owner’s  

Manual. If you cannot set the correct idle  

speed, have your STIHL dealer check  

your saw and make proper adjustments  

or repairs.

Inspect buffers periodically. Replace  

damaged, broken or excessively worn  

buffers immediately, since they may  

result in loss of control of the saw.  

You cannot control reactive forces and  

you may lose control of the saw, which  

can result in the skating or bouncing of  

the bar and chain along the limb or log.  

A “sponginess” in the feel of the saw,  

increased vibration or increased  

“bottoming” during normal operation  

may indicate damage, breakage or  

excessive wear. Buffers should always  

be replaced in sets. If you have any  

questions as to whether the buffers  

should be replaced, consult your STIHL  

servicing dealer.

powerful force used to cut wood can be  

reversed (and work against the opera-  

tor). If the rotating chain is suddenly  

stopped by contact with any solid object  

like a log or branch or is pinched, the  

reactive forces may occur instantly.  

These reactive forces may result in loss  

of control which may, in turn, cause  

serious or fatal injury. An understanding  

of the causes of these reactive forces  

may helpyou avoid loss of control.  

Don’t put pressure on the saw when  

reaching the end of a cut. The pressure  

may cause the bar and rotating chain to  

pop out of the cut or kerf, go out of  

control and strike the operator or some  

other object. If the rotating chain strikes  

some other object, a reactive force may  

cause the moving chain to strike the  

operator.  

The reaction of the cutting force of the  

chain causes a rotational force on the  

chainsaw in the direction opposite to the  

chain movement. This may fling the bar  

up and back in an uncontrolled arc  

mainly in the plane of the bar. Under  

some cutting circumstances the bar  

moves towards the operator, who may  

suffer severe or fatal injury.  

The most common reactive forces are  

– kickback,

pushback,  

pull-in.

Never operate your chainsaw without a  

front hand guard. In a kickback situation  

this guard helps protect your left hand or  

other parts of your body. In addition,  

removal of the hand guard on a saw  

equipped with a chain brake will deactivate  

the chain brake.  

STIHL recommends the use of the STIHL  

Quickstop chain brake on your power-  

head with green labeled reduced kick-  

back bars and low kickback chains.

To reduce the risk of injury, stop using  

the saw immediately if the chain brake

been rectified (see the section “Chain  

Brake”).

Xhꢀvtꢁ  

No Quickstop or other chain brake  

device prevents kickback. These devices  

are designed to reduce the risk of  

kickback injury, if activated, in certain  

kickback situations. In order for the  

Quickstop to reduce the risk of kickback  

injury, it must be properly maintained  

and in good working order. See the  

chapter entitled “Chain Brake” and  

“Maintenance, Repair and Storing” of  

your Owner’s Manual. In addition, there  

must be enough distance between the  

bar and the operator to ensure that the  

Quickstop has sufficient time to activate  

and stop the chain before potential  

contact with the operator.  

Rˆvpx†‡‚ƒꢂpuhvꢂiꢀhxr  

When a kickback occurs, the guide bar  

may rotate around the front handle. If the  

cutting position is such that the operator’s  

left hand is gripping the front handle  

behind the hand guard, and if the left  

hand rotates around the front handle and  

makes a sufficiently forceful contact with  

the front hand guard, which is the Quick-  

stop activating lever, this contact will  

activate the Quickstop. The chain brake  

on most new model STIHL chainsaws  

can also be activated by inertia. See the  

chapter entitled “Chain Brake” of your  

Owner’s Manual.  

STIHL has developed a chain stopping  

system designed to reduce the risk of  

injury in certain kickback situations.  

It is called a Quickstop chain brake.  

The Quickstop is available as standard  

equipment on your STIHL chainsaw and  

is available for installation on most older  

STIHL saws. Ask your dealer to retrofit

match your powerhead with the appro-  

priate bar/chain combinations to reduce  

the risk of kickback injury. Green labeled  

bars and chains are recommended for all

system to help you identify the STIHL  

reduced kickback bars and low kick-  

back chains. Cutting attachments with  

green warning decals or green labels on  

the packaging are designed to reduce  

the risk of kickback injury. The matching

Never run the chainsaw above idle  

speed for more than 3 seconds when  

the chain brake is engaged or the chain  

is pinched or otherwise caught in the cut.  

Clutch slippage can cause excessive  

heat, leading to severe damage of the  

motor housing, clutch and oiler compo-  

nent and may interfere with the operation  

of the chain brake. If clutch slippage in  

excess of 3 seconds has occured, allow  

the motor housing to cool before pro-  

ceeding and check the operation of your  

chain brake as described in the chapter  

entitled “Chain Brake”. Also make sure  

that the chain is not turning at idle speed

Xhꢀvtꢁꢂ  

In order to reduce the risk of personal  

injury, never stand directly behind the  

tree when it is about to fall, since part of  

the trunk may split and come back  

towards the operator (barber-chairing),  

or the tree may jump backwards off the  

stump. Always keep to the side of the  

falling tree. When the tree starts to fall,  

withdraw the bar, shut off the engine and  

walk away on the preplanned escape  

path. Watch out for falling limbs.  

This is the hinge  

Do not cut through the hinge –  

you could lose control of the  

direction of the fall  

This is especially important in soft  

wood in summer - it helps prevent  

sapwood splintering when the tree  

falls.  

Drive wedges into the felling cut where  

necessary to control the fall.  

ꢀ

Xhꢀvtꢁ  

If the tip of the bar contacts a wedge,  

it may cause kickback. Wedges should  

be of wood or plastic – never steel,  

which can damage the chain.

Avoid repositioning the saw more than  

necessary. When repositioning for the  

next cut, keep the guide bar fully engaged  

in the kerf to keep the felling cut straight.  

If the saw begins to pinch, insert a  

wedge to open the cut. On the last cut,  

do not cut the hinge.  

ꢀ

Xhꢀvtꢁ

Be extremely careful with partially fallen  

trees which are poorly supported.  

When the tree hangs or for some other  

reason does not fall completely, set the  

saw aside and pull the tree down with a  

cable winch, block and tackle or tractor.  

If you try to cut it down with your saw,  

you may be injured.  

Xhꢀvtꢁꢂ  

Felling a tree that has a diameter greater  

than the length of the guide bar requires  

use of either the sectioning felling cut or  

plunge-cut method. These methods are  

extremely dangerous because they  

involve the use of the nose of the guide  

bar and can result in kickback. Only  

properly trained professionals should  

attempt these techniques.

Timber having a diameter more than  

twice the length of the guide bar requires  

the use of the plunge-cut method before  

making the felling cut.  

†v€ƒyrꢂshꢂpˆ‡  

Trp‡v‚vtꢂ€r‡u‚q  

Engage the bumper spikes of the chain-  

saw directly behind the location of the  

intended hinge and pivot the saw around  

this point only as far as the hinge. The  

bumper spike rolls against the trunk.  

For the sectioning method make the first  

part of the felling cut with the guide bar  

fanning in toward the hinge. Then, using  

the bumper spike as a pivot, reposition  

the saw for the next cut.  

!

If you are inexperienced with a chainsaw,  

plunge-cutting should not be attempted.  

Seek the help of a professional.

Limbing is removing the branches from  

a fallen tree.  

ꢀ

Xhꢀvtꢁ  

First, cut a large, wide felling notch.  

Make a plunge cut in the center of the  

notch.  

There is an extreme danger of kickback  

during the limbing operation. Do not  

work with the nose of the bar. Be extremely  

cautious and avoid contacting the log or  

other limbs with the nose of the guide bar.  

The plunge cut is made with the guide  

bar nose. Begin the plunge cut by  

applying the lower portion of the guide  

bar nose to the tree at an angle. Cut until  

the depth of the kerf is about the same as  

the width of the guide bar. Next, align  

the saw in the direction in which the  

recess is to be cut.  

Do not stand on a log while limbing it –  

you may slip or the log may roll.  

Start limbing by leaving the lower limbs to  

support the log off the ground. When  

underbucking freely hanging limbs,  

a pinch may result or the limb may fall,  

causing loss of control. If a pinch occurs,  

stop the engine and remove the saw,  

by lifting the limb.

Bucking is cutting a log into sections.  

ꢀ

With the saw at full throttle, insert the  

guide bar in the trunk.  

Xhꢀvt†ꢁꢂ  

1. When bucking, do not stand on the  

log. Make sure the log will not roll  

downhill. If on a slope, stand on the  

uphill side of the log.  

Enlarge the plunge cut as shown in  

illustration.  

ꢀ

Xhꢀvtꢁ  

Be extremely cautious when cutting  

limbs or logs under tension (spring poles).  

The limbs or logs could spring back  

toward the operator and cause loss of  

control of the saw and severe or fatal  

injury to the operator.  

Watch out for rolling logs.  

ꢀ

Xhꢀvtꢁ  

There is an extreme danger of kickback  

at this point. Extra caution must be taken  

to maintain control of the saw. To make  

the felling cut, follow the sectioning  

method described previously.

Shattered wood should be cut very  

carefully. Sharp slivers of wood  

may be caught and flung in the  

direction of the operator of the saw.  

Then make bucking cut (!) at  

tension side (7).  

If the saw pinches, stop the engine

Xhꢀvtꢁ  

Use only STIHL replacement parts for  

maintenance and repair. Use of parts  

manufactured by others may cause  

serious or fatal injury.

When cutting small logs, place log  

through “V” - shaped supports on  

top of a sawhorse. Never permit  

another person to hold the log.  

Never hold the log with your leg or  

foot.

a spark-arresting screen to reduce the  

risk of fire (e. g. in the USA, Canada and  

Australia), never operate your saw if the  

screen is missing or damaged. Remem-  

ber that the risk of forest fires is greater  

in hot or dry weather.  

Keep the chain, bar and sprocket clean;  

replace worn sprockets or chains.  

Keep the chain sharp.  

You can spot a dull chain when easy-to-  

cut wood becomes hard to cut and burn  

marks appear on the wood.  

Keep the chain at proper tension. Tighten  

all nuts, bolts and screws except the  

carburetor adjustment screws after each  

use.  

For the proper and effective operation of  

the chain brake the brake band and  

clutch drum must be kept free of dirt,

may reduce friction of the band on the  

drum.

Xhꢀvtꢁ  

To reduce the risk of fire and burn injury,  

use only spark plugs authorized by  

STIHL. Always press spark plug boot  

snugly onto spark plug terminal of the  

proper size. (Note: If terminal has  

detachable SAE adapter nut, it must be  

attached.) A loose connection between  

spark plug terminal and ignition wire  

connector in the boot may create arcing  

that could ignite combustible fumes and  

cause a fire. Keep spark plug clean, and  

make sure ignition lead is in good  

condition.  

The chainsaw should also be returned  

immediately for maintenance whenever  

the brake system cannot be thoroughly  

cleaned or there is a change in its  

operating characteristics.  

ꢀ

Xhꢀvtꢁꢂ  

In order for the chain brake on your  

STIHL chainsaw to properly perform its  

function of reducing the risk of kickback  

and other injuries, it must be properly  

maintained. Like an automobile brake,  

a chainsaw chain brake incurs wear  

each time it is engaged.  

For any maintenance please refer to the  

maintenance chart hqꢂ‡‚ꢂ‡urꢂhꢀꢀh‡’  

†‡h‡r€r‡near the end of this manual.  

ꢀ

Xhꢀvtꢁ  

The amount of wear will vary depending  

upon usage, conditions under which the  

saw is used and other factors. Excessive  

wear will reduce the effectiveness of the  

chain brake and can render it inoperable.  

Additionally, the daily maintenance  

schedule for your chainsaw set forth in  

your STIHL Owner’s Manual should be  

strictly followed.  

Do not operate your chainsaw if the  

muffler is damaged, missing or modified.  

An improperly maintained muffler will  

increase the risk of fire and hearing loss.  

Never touch a hot muffler or burn will  

Store chainsaw in a dry place and away  

from children. Before storing for longer

This engine is certified to operate on  

unleaded gasoline and oil with the  

mix ratio 50:1.  

We recommend STIHL 50:1 two-stroke  

engine oil since it is specially formulated  

for use in STIHL engines.  

Your two-stroke engine requires a  

mixture of brand-name gasoline and  

quality two-stroke engine oil with the  

FODVVLILFDWLRQꢀ7&ꢁ  

Do not use BIA or TCW (two-stroke  

water cooled) mix oils!  

Take care when handling gasoline.  

Avoid direct contact with the skin and  

avoid inhaling fuel vapour  

Use regular branded unleaded gasoline  

with a minimum octane rating of  

(see “Safety Precautions”).  

MIX  

90 ROZ (U.S.A./Canada: pump octane  

min. 89!). If the octane number of the  

regular grade gasoline in your area is  

lower, use premium unleaded fuel.  

Fuel with a lower octane rating may  

result in preignition (causing “pinging”)  

which is accompanied by an increase in  

engine temperature. This, in turn,  

increases the risk of piston seizure  

and damage to the engine.  

The canister should be kept tightly  

closed in order to avoid any moisture  

getting into the mixture.  

The fuel tank and the canister in which  

fuel mix is stored should be cleaned  

from time to time.  

)XHOꢀPL[ꢀDJHVꢂ  

Only mix sufficient fuel for a few days  

work, not to exceed 3 months of storage.  

Store in approved safety fuel-canisters  

only. When mixing, pour oil into the  

canister first, and then add gasoline.  

Before fueling, clean the fuel filler cap  

and the area around it to ensure that no  

dirt falls into the tank.  

Always thoroughly shake the mixture in  

the canister before fueling your machine.  

The chemical composition of the fuel is  

also important. Some fuel additives not  

only detrimentally affect elastomers  

(carburetor diaphragms, oil seals, fuel  

lines etc.), but magnesium castings as  

well. This could cause running problems  

or even damage the engine. For this  

reason it is essential that you use only  

branded fuels!  

Use only STIHL two-stroke engine oil or  

equivalent branded two-stroke air-  

cooled engine oils with the classification  

TC for mixing.

are difficult to remove, especially in the  

area of the chain drive, clutch and chain.  

It may even cause the oil pump to seize.  

MIX  

The service life of the chain and guide  

bar depends on the quality of the  

lubricant. It is therefore essential to use  

only a specially formulated chain  

lubricant.  

Change the fuel pick up body every year.  

Thoroughly clean the oil filler cap  

and the area around it to ensure  

that no dirt falls into the tank.

Before storing your machine for a long  

period, drain and clean the fuel tank and  

run engine until carburetor is dry.  

If special chain lubricant is not available,  

you may - in an emergency - use an HD  

single grade or multigrade engine oil  

with a viscosity that suits the prevailing  

outside temperature.  

Refill the chain oil tankꢀevery time  

you refuel.  

There must still be a small amount of oil  

in the oil tank when the fuel tank is  

empty.  

If the oil tank is still partly full, the reason

The choke lever is mechanically connected to the carbure-  

tor’s choke valve. The choke valve is closed when the choke  

lever is on I and open whenthe chokelever ismovedaway  

from I.  

When starting a cold engine only keep the choke slide in the  

I position until the engine begins to fire. Even if you do not  

hear the engine firing, always open the choke after pulling  

the starter rope three or four times. If you leave the choke  

slide in the I position, the combustion chamber will flood  

and stall the engine.  

If you have moved the choke slide away from I after the  

engine has fired or after three or four pulls on the starter  

rope and the engine still refuses to start, you can assume  

that the combustion chamber is already flooded. In such a  

case, remove and dry off the spark plug. With the spark plug  

still removed and the stop switch on G, clear the combus-  

tion chamber by cranking the engine several times on the  

starter. When you now try to start, move the choke lever  

away from I and set the throttle trigger to the start position.  

The stop switch should again be moved away from G.

In very cold weather only open the choke partially after the  

engine begins to fire – move choke lever to about the center  

position. Allow engine to warm up for a brief period with the

pletely away from I and disengage the starting throttle

Checking chain lubrication  

*XLGHꢀ%DU  

The nose and underside of the guide bar are subject to a  

particularly high rate of wear. To avoid one-sided wear, turn  

the bar over every time you resharpen or preplace the chain.  

Regular cleaning of the oil inlet holes and guide bar groove  

is also important. The bar can be examined for signs of wear  

at the same time.  

A minimum bar groove depth must be maintained in order  

to prevent the drive links contacting the bottom of the groove  

(the heels of the cutter and tie strap would no longer on the  

guide bar rails). The groove depth varies according to chain  

type and pitch:  

%UHDNLQJꢀLQꢀ2LORPDWLFꢀ&KDLQ  

Chain type  

Picco  

Chain pitch  

3/8 "  

Minumum depth  

5 mm (0.2")  

Every new chain has tobebroken in forabout2to3minutes.  

Ample chain lubrication is essential during this period. After  

breaking in, stop the engine, check chain tension and adjust  

if necessary.  

The groove depth should be measured at the point where  

the bar is stressed most. That is the bar nose on Duromatic  

bars and the area where most of the cutting is done in  

Rollomatic bars. The guide bar must be replaced when  

groove depth is less than the specified minimum.  

&KDLQꢀ/XEULFDWLRQ  

Never operate the chain saw without proper chain lubrica-  

tion. If the chain is allowed to run dry the whole cutting  

attachment will be irretrievably damaged within a very short  

time. For this reason you should always check operation of  

the chain lubrication system and the level in the oil tank  

before starting work.  

On Rollomatic guide bars it is not necessary to separately  

lubricate the sprocket nose bearing because the chain oil  

which flows to the bearing by way of the bar groove during  

normal operation is adequate for lubrication.  

Start the saw and hold the cutting attachment over a light  

patch of ground. Take care – the Oilomatic chain must not  

touch the ground; hold it at least 20 cm (8 in) clear of the  

ground. Run theengineatabouthalfthrottle. Ifanincreasing  

film of oil can be seen on the ground, chain lubrication is  

operating correctly. If this is not the case, refer to "Trouble-  

shooting on Chain Oiling System".  

ꢅꢇ  

Worn chain sprocket  

&KDLQꢀ7HQVLRQ  

Apart from chain lubrication, chain tension is the factor that  

has the greatest influence of the cutting attachment’s useful  

life. It is therefore necessary to check chain tension before  

starting work and at regular short intervals during cutting  

work. Chain tension is correct in the cold condition when the  

chain fits snugly against the underside of the bar and can  

still be pulled along the bar by hand (wear gloves!).  

As it warms up to normal operating temperature the chain  

expands and sags noticeably. The saw chain must be  

retensioned when the drive links begin to come out of the  

groove on the underside of the bar. If this is not done, there  

is a risk of the chain jumping off the bar.  

&KDLQꢀ6SURFNHW  

The stress and strain on the chain sprocket are particularly  

high. If the wear marks on the teeth are very pronounced  

(about 0.5 mm/0.02 in deep), the sprocket should be  

replaced. A worn sprocket reduces the service life of the  

saw chain. The chain sprocket should be replaced as a  

matter of routine with every second Oilomatic chain. It is  

best to use saw chains alternately with one sprocket.  

If the chain is retensioned during cutting work it must always  

be slackened off again after finishing work. This is neces-  

sary because high contraction stresses would otherwise  

occur as the chain cools down to ambient temperature,  

especially at extremely low outside temperatures, and  

cause damage to the crankshaft and bearings.  

A new chain must be retensioned more frequently than a  

used one because it stretches during the initial break-in  

period.

If you have checked chain lubrication (see chapter "Guide

ment.  

&OHDQLQJꢀWKHꢀ2LOꢀ3XPS  

Drain the chain oil tank. Remove the fastening screws ꢁꢄꢃ  

and withdraw the oil pump.  

If the oil pump is stuck, use a screwdriver to carefully pry it  

away from the crankcase.  

To do this, remove the chain sprocket cover, guide bar  

and chain. Thoroughly clean the oil inlet holes as well  

as the passage between the holes and the bar groove. Also  

clean away dirt that may have collected at the end of the oil  

hose ꢁꢂꢃ and the area around it.  

Pull off the hose ꢁꢅꢃ and remove the polymere disc ꢁꢆꢃ. Take  

the filter ꢁꢇꢃ off the stub. Now pull the cover ꢁꢈꢃ off the pump  

housing, making sure that the diaphragm ꢁꢉꢃ does not stick  

to the cover and tear.  

Now check oil delivery again. If no oil emerges from  

the hose ꢁꢂꢃ, the oil pump must be removed from the  

machine and cleaned.  

Take the plunger and diaphragm ꢁꢉꢃ out of the pump  

housing and remove the two gaskets ꢁꢍꢌꢀꢂꢎꢃꢏ Note the  

spring ꢁꢊꢃ between the pump housing and diaphragm. It  

must not be lost.  

Carefully wash the pump housing, cover, plunger with dia-  

phragm and the filter in clean gasoline. Thoroughly clean  

the gaskets and flange faces on the crankcase.  

Reassemble the pump by reversing the above sequence.  

Coat the plunger with a little lubricating oil before refitting.

The intake air flows to the underside of the filter element. It  

follows that only the underside of the element becomes  

dirty. It is therefore necessary to remove the element and  

turn it over to check its condition.

Ordering Spare Parts  

Storing the Machine  

Please enter your saw model, machine

Warranty claims following repairs  

can be accepted only if the repair has  

been performed by an authorized STIHL  

Service Shop using original STIHL spare  

parts.  

For periods of about 3 months or longer:  

Drain and clean the fuel tank in a  

well ventilated area.  

Run engine until carburetor is dry -  

this helps prevent the carburetor  

diaphragms sticking together.

Original STIHL parts can be identified by  

the STIHL part number, the T  

logo and the STIHL parts symbol ꢀ  

The guide bar, saw chain and chain  

sprocket are subject to normal wear and  

tear.  

Remove the saw chain and guide  

bar, clean them and protect  

with corrosion inhibiting oil.  

•

The symbol may appear alone  

on small parts.  

Thoroughly clean the machine -  

pay special attention to the  

cylinder fins and air filter.  

If you use a biological chain and  

bar lubricant, e.g. STIHL Bioplus,  

completely fill the chain oil tank.  

•

The part numbers of the standard bar,  

chain and sprocket are printed on the  

right for your convenience.  

•

When purchasing these parts, always  

quote the saw model, the part numbers  

and names of the parts.
