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.  

ꢀ

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.

.

With a basic understanding of  

kickback, you can reduce or eli-  

minate the element of surprise.  

Sudden surprise contributes to  

accidents.  

7. Only use replacement bars and  

chains specified by the manu-  

facturer or the equivalent.  

8. Reduced kickback bars and low  

kickback chains are designed  

to reduce the risk of kickback  

injury. Ask your STIHL dealer  

about these devices.  

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 run-  

ning. Use a firm grip with  

thumbs and fingers encircling  

the chainsaw handles.  

%ꢀꢁ2WKHUꢁ6DIHW\ꢁ3UHFDXWLRQV  

1. Do QRW operate a chainsaw with  

one hand! Serious injury to the  

operator, helpers, bystanders,  

or any combination of these  

persons may result from one-  

handed operation. A chainsaw  

is intended to be used with two  

hands.  

A firm grip will help you reduce  

kickback and maintain control  

of the saw.  

Section 5.12 of ANSI B 175.1-1991  

sets certain performance and  

design criteria related to chainsaw  

kickback. STIHL has developed a  

color code system using green and  

yellow to help you select a power-  

head, bar and chain combination  

that complies with the kickback  

requirements of the ANSI Standard.  

See the sections entitled "Safety  

Precautions" and "Specifications"  

of this manual.  

Don’t let go.  

3.  

Make sure the area in which you  

are cutting is free from obstruc-  

tions. Do not let the nose of the  

guide bar contact a log, branch,  

or any other obstruction while  

you are operating the saw.  

2. Do not operate a chainsaw when  

you are fatigued.  

3. Use safety footwear; snug-fitting  

clothing; protective gloves; and  

eye, hearing, and head protect-  

ion devices.

Your STIHL 036 QS is equipped with  

an additional chain braking system  

activated by removing the hand from the  

rear handle. As before, the chain brake  

can be activated manually by pushing  

the front hand guard toward the bar  

nose or by inertia in certain kickback  

situations. In addition, the new system,  

which utilizes a different braking  

mechanism, is designed to stop chain  

rotation within a second of you letting go  

of the rear handle. The locked chain is  

not released until you press down the  

throttle trigger interlock lever again to  

operate the throttle.  

The QS braking system may be  

activated in three ways:  

:DUQLQJꢀ  

Due to the way it functions, the QS  

braking system may cause the saw to  

react in an unaccustomed manner. To  

avoid personal injury during cutting,  

observe the characteristics that make  

the STIHL 036 QS different from saws  

that do not have such a braking system.  

Before operating the STIHL 036 QS for  

the first time, make sure you are familiar  

with how the QS system works. Pay  

special attention to the chapters "Chain  

Brake" and "Starting" in this manual.

the big advantages of this system is  

that the saw chain is locked when  

carrying the running saw by the front

51  

Because a chainsaw 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.  

After Finishing Work  

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.

The use of any chainsaw  

may be hazardous.  

The saw chain has many  

sharp cutters. If the  

cutters contact your flesh,  

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.  

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.

observe the following safety precautions  

and warnings. Read the owner’s  

manual hqꢀthe safety instructions  

periodically.

All safety precautions that are generally  

observed when working with an axe or a

Protect your hands with  

gloves when handling  

saw and saw chain.  

Heavy-duty, nonslip  

gloves improve your grip  

and protect your hands.  

Xhꢁvtꢂꢀ  

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.  

Keep the saw chain sharp and the  

saw, including the AV system, well  

maintained. A dull chain will  

increase cutting time, and pressing  

a dull chain through wood will  

increase the vibrations transmitted  

to your hands. A saw with loose  

components or with damaged or  

worn AV buffers will also tend to  

have higher vibration levels.  

Maintain a firm grip at all times, but  

do not squeeze the handles with  

constant, excessive pressures, take  

frequent breaks.  

Good footing is most  

important in chainsaw  

work. Wear sturdy boots  

with nonslip soles.  

Steel-toed safety boots  

UC@ꢀVT@ꢀPAꢀUC@ꢀT6X  

are recommended.

To reduce the risk of injury to your eyes  

never operate a chainsaw unless wear-

glasses with adequate top and side  

protection complying with ANSI Z 87.1.

ꢀ

Xhꢁvtꢂꢀ  

Always stop the engine before putting a  

chainsaw down or carrying it. Carrying a  

chainsaw with the engine running is  

extremely dangerous. Accidental accel-  

eration of the engine can cause the chain  

to rotate. During operation, the power-  

head muffler and the material around it  

reach extremely high temperatures.  

Avoid touching the hot muffler, you could  

receive serious burns.  

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.  

Wear an approved safety  

hard hat to protect your  

head. Chainsaw noise  

may damage your  

hearing. Always wear  

sound barriers (ear plugs  

or ear mufflers) to protect your hearing.  

Continual and regular users should have  

their hearing checked regularly.

Gasoline is an extremely flammable fuel.  

If spilled and 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.  

Take off the chain guard and inspect for  

safety in operation. For assembly, follow  

the procedure described in the chapter  

"Mounting the Bar and Chain" of your  

owner’s manual.  

STIHL Oilomatic chain, guide bar and  

sprocket must match each other in  

gauge and pitch.  

Before replacing any bar and chain, see  

the sections on "Specifications", kick-  

back and the ANSI B 175.1-1991 chain-  

saw kickback standard in this manual.  

Do not smoke or bring  

any fire or flame near the  

fuel or the chainsaw.  

Note that combustible  

fuel vapors may be ven-  

ted from the fuel system..

Xhꢁvtꢂꢀ  

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 !  

Fuel your chainsaw in well-ventilated  

areas, outdoors only.  

Always shut off the engine and allow it to  

cool before refueling. 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 the risk of burns or other  

personal injury from escaping gas vapor  

and fumes, remove the gas 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.  

Grip the front handle and place the  

muffler away from the body.  

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.  

When removing the scabbard be careful  

not to contact the chain.  

7’ꢀ‰ruvpyr)When 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.  

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.  

Aˆryvt  

Your STIHL chainsaw uses an oil-gaso-  

line mixture for fuel (see chapter "Fuel"  

of your owner’s manual).  

'

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.  

ꢀ

Xhꢁvtꢂ  

Unit vibrations can cause an improperly  

tightened fuel cap to loosen or come off  

and spill quantities of fuel. In order to re-  

duce risk of fuel spillage and fire, tighten  

fuel cap by hand with as much force as  

possible.  

The screwdriver end of  

the STIHL combination  

wrench or other similar  

tool can be used as an aid  

in tightening slotted fuel  

caps.

or other solid surface in an open area.  

Maintain good balance and secure  

footing.  

The †rp‚qrecommended €r‡u‚qꢀfor  

starting your chainsaw allows you to  

start the saw without placing it on the  

ground. Make sure the chain brake is  

engaged, grip the front handle of the  

chainsaw firmly with your left hand.  

Keep the arm on the front handle in a  

locked (straight) position. Hold the rear  

handle of the saw tightly between your  

legs just above the knees. On "QS"  

models, be careful not to disengage the  

chain brake by depressing the interlock  

lever with your leg. Maintain good  

balance and secure footing. Pull the  

starting grip slowly with your right hand  

until you feel a definite resistance and  

then give it a brisk, strong pull.

Your chainsaw is a one-person saw.  

Do not allow other persons to be near  

the running chainsaw. Start and operate  

your saw without assistance. For  

specific starting instructions, see the  

appropriate section of the Owner’s  

Manual. Proper starting methods reduce  

the risk of injury. Do not drop start. This  

method is very dangerous because you  

may lose control of the saw.  

Grip the front handlebar of the saw firmly  

with your left hand and press down.  

For saws with a rear handle level with  

the ground, put the toe of your right foot  

into the rear handle and press down.  

With your right hand pull out the starter  

grip slowly until you feel a definite  

resistance and then give it a brisk, strong  

pull.  

There are two recommended methods  

for starting your chainsaw.

ventilated locations. Ensure proper venti-  

lation when working in trenches or other  

confined areas.  

Even an oil mist (from chain lubrication)  

and sawdust are health hazards.  

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-  

brake is not activated, turn the chain.  

If the upper quadrant of the tip of the bar  

touches any object, it may cause kick-  

back to occur (see section on reactive  

forces). Never attempt to start the chain-  

saw when the guide bar is in a cut or  

kerf.  

ꢀ

Xhꢁvtꢂ  

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.  

The muffler and other parts of the engine  

(e.g. fins of the cylinder, spark plug)  

become hot during operation and remain  

hot for a while after stopping the engine.  

To reduce risk of burns do not touch the  

muffler and other parts while they are  

hot. Operate the saw under good  

visibility and daylight conditions only.  

Don’t work alone. Keep within calling  

distance of others in case help is  

needed.  

After adjusting a chain, start the saw, let  

the engine run for a while, then switch  

engine off and recheck chain tension.  

Proper chain tension is very important at  

all times.  

Xhꢁvtꢂ  

On "QS" models, as soon as you press  

down the interlock lever, the chain brake  

is disengaged and allows the chain to  

run at high speed until you blip the  

throttle trigger and release the interlock  

lever again.  

Your chainsaw is equipped with a chain  

catcher. It is designed to reduce the risk  

of personal injury in the event of a thrown  

or broken chain. From time to time the  

catcher may be damaged or removed.  

To reduce the risk of personal injury,  

do not operate a chainsaw with a  

damaged or missing catcher.  

Inspect buffers periodically. Replace  

damaged, broken or excessively worn  

buffers immediately, since they may  

result in loss of control of the saw.  

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.  

X‚ꢁxvtꢀ8‚qv‡v‚†  

Xhꢁvtꢂ  

Operate the chainsaw under good  

visibility and daylight conditions only.  

When you pull the starter grip, do not  

wrap the starting rope around your  

hands. Do not allow the grip to snap  

back, but guide the starter rope slowly  

back to permit the rope to rewind pro-  

perly. Failure to follow this procedure  

may result in injury to hand or fingers  

and may damage the starter mechanism.  

^ꢀXhꢁvtꢂ  

Your chainsaw produces  

poisonous exhaust fumes  

as soon as the combusti-  

ble engine is running.  

These gases (e.g. carbon  

monoxide) may be colorless and odor-  

less.  

To reduce the risk of serious or fatal  

injury from breathing toxic fumes, never  

run the chainsaw indoors or in poorly

Xhꢁvtꢂ  

Avoid stumbling on obstacles such as  

stumps, roots or rocks and watch out for

Do not operate your chainsaw with the  

starting throttle lock engaged. Cutting

control of the saw or chain speed.  

Do not cut any material other than wood  

or wooden objects. Use your chainsaw  

for cutting only. It is not designed for  

prying or shoveling away limbs, roots or  

other objects. When sawing, make sure  

that the saw chain does not touch any  

foreign materials such as rocks, fences,  

nails and the like.  

Position the chainsaw in such a way that  

your body is clear of the cutting attach-  

ment whenever the engine is running.  

Stand to the left of cut while bucking.  

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 help  

you 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 most common reactive forces are  

– kickback,  

– pushback,  

– pull-in.  

Such objects may be flung off, damage  

the saw chain or cause the saw to kick-  

back.  

Fvpxihpx)  

Kickback occurs when  

the upper quadrant of the  

bar nose contacts a solid  

object or is pinched.  

In order to keep control of your saw,  

always maintain a firm foothold. Never  

work on a ladder, or on any other  

insecure support. Never use the saw  

above shoulder height.  

Srhp‡v‰rꢀs‚ꢁpr†ꢀvpyˆqvtꢀxvpxihpx  

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.

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.  

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 chain saw.  

When a kickback occurs, the guidebar  

may rotate around the front handle.  

If the cutting position is such that the  

operator’s left hand ist gripping the front  

handle behind the hand guard, and if the  

left hand rotates around the front handle  

and pushes forward the front hand  

guard, which is the Quickstop activating  

lever, this contact will activate the Quick-  

stop. The chain brake on most new  

model STIHL chain saws can also be  

activated by inertia. On QS" models, the  

interlock lever and the throttle trigger on  

the rear handle act as a third means of  

activation. See the chapter entitled

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.

straight. If the saw begins to pinch, insert  

a wedge to open the cut. On the last cut,  

do not cut the hinge.  

First, cut a large, wide felling notch.  

Make a plunge cut in the center of the

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.  

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 re-  

cess is

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.  

With the saw at full throttle, insert the  

guide bar in the trunk.

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.  

If you are inexperienced with a chainsaw,  

plunge-cutting should not be attempted.

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.  

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.  

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.

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.  

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

Additionally, the daily maintenance  

schedule for your chainsaw set forth in  

your STIHL Owner’s Manual should be  

strictly followed.  

(see chapter "Chain Brake").  

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.  

For the proper and effective operation of  

the chain brake the brake band and  

clutch drum must be kept free of dirt,  

grease and other foreign matter which  

may reduce brake performance on the  

drum.  

Store chainsaw in a dry place and away  

from children. Before storing for longer  

than a few days, always empty the fuel  

tank.  

For these reasons, each STIHL chain-  

saw should be returned to trained  

personnel such as your STIHL servicing  

dealer for periodic inspection and  

servicing of the brake system according  

to the following schedule:  

Heavy usage - every three months,  

Moderate usage - twice a year,  

Occasional usage - annually.

resistant to aging (e.g. STIHL Bioplus)  

since it will otherwise quickly turn to  

resin. This results in hard deposits that  

are difficult to remove, especially in the  

area of the chain drive, clutch and chain.  

It may even cause the oil pump to seize.  

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.  

Thoroughly clean the oil filler cap  

and the area around it to ensure  

that no dirt falls into the tank.

checked and serviced regularly by  

trained personnel (e.g. STIHL dealer)  

at the following intervals:  

If the engine idling speed is set too high,  

the chain may start to rotate when the  

hand guard is pulled back.

A factory new machine should not be  

run at high revs (full throttle off load)  

for the first three tank fillings. This avoids  

unnecessary high loads during the  

break-in period.

As all moving parts have to bed in  

during the break-in period, the frictional  

resistances in the engine are greater  

during this period. The engine develops  

its maximum power after about 5 to 15  

tank fillings.  

Tension is correct when chain fits snugly  

against the underside of the bar and can  

still be pulled along the bar by hand.

Avoid touching the tie straps and  

drive links with the file.  

Rotate the file at regular intervals  

while filing -

this avoids one-sided wear.

If you use a file holder or the FG 1:  

Leave the chain on the bar.  

Clamp the bar in a vise if necessary.  

Lock the chain - push hand guard  

forward  

To rotate the chain - pull hand  

guard against front handle  

Sharpen chain frequently, take  

away as little metal as possible -  

two or three strokes of the file are  

usually enough  

If the cutters are not the same length,  

they will have different heights. This  

makes the chain run roughly and can  

cause it to break.
