SAFETY RULES

WARNING: Always disconnect

spark plug wire and place wire where it can-

not contact spark plug to prevent accidental

starting when setting up, transporting, ad-

justing or making repairs except carburetor

adjustments.

Because a chain saw is a high-speed wood-

cutting tool, special safety precautions must

be observed to reduce the risk of accidents.

Careless or improper use of this tool can

cause serious injury.

PLAN AHEAD

S Read this manual carefully until you com-

pletely understand and can follow all safe-

ty rules, precautions, and operating in-

structions before attempting to use the

unit.

S Restrict the use of your saw to adult users

who understand and can follow safety

rules, precautions, and operating instruc-

tions found in this manual.

S Wear protective gear. Always use steel-

toed safety footwear with non-slip soles;

snug-fitting clothing; heavy-duty, non-slip

gloves; eye protection such as non-fog-

ging, vented goggles or face screen; an

approved safety hard hat; and sound barri-

ers (ear plugs or mufflers) to protect your

hearing. Regular users should have hear-

ing checked regularly as chain saw noise

can damage hearing. Secure hair above

shoulder length.

S Keep all parts of your body away from the

chain when the engine is running.

S Keep children, bystanders, and animals a

minimum of 10 Meters away from the work

area. Do not allow other people or animals

to be near the chain saw when starting or

operating the chain saw.

S Do not handle or operate a chain saw

when you are fatigued, ill, or upset, or if you

have taken alcohol, drugs, or medication.

You must be in good physical condition

and mentally alert. Chain saw work is

strenuous. If you have any condition that

might be aggravated by strenuous work,

check with your doctor before operating a

chain saw.

S Carefully plan your sawing operation in ad-

vance. Do not start cutting until you have a

clear work area, secure footing, and, if you

are felling trees, a planned retreat path.

OPERATE YOUR SAW SAFELY

S Do not operate a chain saw with one hand.

Serious injury to the operator, helpers, by-

standers or any combination of these per-

sons may result from one-handed opera-

tion. A chain saw is intended for

two-handed use.

S Operate the chain saw only in a well-venti-

lated outdoor area.

S Do not operate saw from a ladder or in a

tree, unless you are specifically trained to

do so.

S Make sure the chain will not make contact

with any object while starting the engine.

Never try to start the saw when the guide

bar is in a cut.

S Do not put pressure on the saw at the end of

the cut. Applying pressure can cause you to

lose control when the cut is completed.

S Stop the engine before setting the saw

down.

S Do not operate a chain saw that is dam-

aged, improperly adjusted, or not com-

pletely and securely assembled. Always

replace bar, chain, hand guard, or chain

brake immediately if it becomes damaged,

broken or is otherwise removed.

S With the engine stopped, hand carry the

chain saw with the muffler away from your

body, and the guide bar and chain to the

rear, preferably covered with a scabbard.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

S Have all chain saw service performed by a

qualified service dealer with the exception of

the items listed in the maintenance section of

this manual. For example, if improper tools

are used to remove or hold the flywheel

when servicing the clutch, structural damage

to the flywheel can occur and cause the fly -

wheel to burst.

S Make certain the saw chain stops moving

when the throttle trigger is released. For

correction, refer to CARBURETOR AD-

JUSTMENTS.

S Never modify your saw in any way. Use

only attachments supplied or specifically

recommended by the manufacturer.

S Keep the handles dry, clean, and free of oil

or fuel mixture.

S Keep fuel and oil caps, screws, and fas-

teners securely tightened.

S Use only JonseredR accessories and re-

placement parts as recommended.

HANDLE FUEL WITH CAUTION

S Do not smoke while handling fuel or while

operating the saw.

S Eliminate all sources of sparks or flame in

the areas where fuel is mixed or poured.

There should be no smoking, open flames,

or work that could cause sparks. Allow en-

gine to cool before refueling.

4

S Mix and pour fuel in an outdoor area on bare

ground; store fuel in a cool, dry, well venti-

lated place; and use an approved, marked

container for all fuel purposes. Wipe up all

fuel spills before starting saw.

S Move at least 10 feet (3 meters) from fuel-

ing site before starting engine.

S Turn the engine off and let saw cool in a

non-combustible area, not on dry leaves,

straw, paper, etc. Slowly remove fuel cap

and refuel unit.

S Store the unit and fuel in an area where fuel

vapors cannot reach sparks or open

flames from water heaters, electric motors

or switches, furnaces, etc.

KICKBACK

WARNING: Avoid kickback which

can result in serious injury. Kickback is the

backward, upward or sudden forward motion

of the guide bar occurring when the saw

chain near the upper tip of the guide bar con-

tacts any object such as a log or branch, or

when the wood closes in and pinches the

saw chain in the cut. Contacting a foreign ob-

ject in the wood can also result in loss of

chain saw control.

S Rotational Kickback can occur when the

moving chain contacts an object at the up-

per tip of the guide bar. This contact can

cause the chain to dig into the object,

which stops the chain for an instant. The

result is a lightning fast, reverse reaction

which kicks the guide bar up and back to-

ward the operator.

S Pinch-Kickback can occur when the the

wood closes in and pinches the moving

saw chain in the cut along the top of the

guide bar and the saw chain is suddenly

stopped. This sudden stopping of the

chain results in a reversal of the chain

force used to cut wood and causes the

saw to move in the opposite direction of the

chain rotation. The saw is driven straight

back toward the operator.

S Pull-In can occur when the moving chain

contacts a foreign object in the wood in the

cut along the bottom of the guide bar and the

saw chain is suddenly stopped. This sudden

stopping pulls the saw forward and away

from the operator and could easily cause the

operator to lose control of the saw.

Avoid Pinch -- Kickback:

S Be extremely aware of situations or obstruc-

tions that can cause material to pinch the top

of or otherwise stop the chain.

S Do not cut more than one log at a time.

S Do not twist the saw as the bar is with-

drawn from an undercut when bucking.

Avoid Pull -- In:

S Always begin cutting with the engine at full

speed and the saw housing against wood.

S Use wedges made of plastic or wood.

Never use metal to hold the cut open.

REDUCETHECHANCEOF

KICKBACK

S Recognize that kickback can happen.

With a basic understanding of kickback,

you can reduce the element of surprise

which contributes to accidents.

S Never let the moving chain contact any ob-

ject at the tip of the guide bar.

S Keep the working area free from obstruc -

tions such as other trees, branches, rocks,

fences, stumps, etc. Eliminate or avoid any

obstruction that your saw chain could hit

while you are cutting through a particular log

or branch.

S Keep your saw chain sharp and properly

tensioned. A loose or dull chain can increase

the chance of kickback occurring. Follow

manufacturer’s chain sharpening and main-

tenance instructions. Check tension at regu-

lar intervals with the engine stopped, never

with the engine running. Make sure the bar

clamp nuts are securely tightened after ten-

sioning the chain.

S Begi nand continue cutting at full speed. If

the chain is moving at a slower speed,

there is greater chance of kickback occur-

ring.

S Cut one log at a time.

S Use extreme caution when re-entering a

previous cut.

S Do not attempt cuts starting with the tip of

the bar (plunge cuts).

S Watch for shifting logs or other forces that

could close a cut and pinch or fall into chain.

S Use the Reduced-- Kickback Guide Bar

and Low-- Kickback Chain specified for

your saw.

MAINTAIN CONTROL

Never reverse

hand positions

Stand to the left of

the saw

Thumb on underside of

handlebar

Elbow locked

S Keep a good, firm grip on the saw with both

hands when the engine is running and

don’t let go. A firm grip will help you reduce

kickback and maintain control of the saw.

Keep the fingers of your left hand encir-

cling and your left thumb under the front

handlebar. Keep your right hand com-

pletely around the rear handle whether

your are right handed or left handed. Keep

your left arm straight with the elbow

locked.

S Position your left hand on the front handle-

bar so it is in a straight line with your right

hand on the rear handle when making

bucking cuts. Never reverse right and left

hand positions for any type of cutting.

S Stand with your weight evenly balanced on

both feet.

S Stand slightly to the left side of the saw to

keep your body from being in a direct line

with the cutting chain.

S Do not overreach. You could be drawn or

thrown off balance and lose control of the

saw.

S Do not cut above shoulder height. It is diffi-

cult to maintain control of saw above

shoulder height.

KICKBACK SAFETY FEATURES

WARNING: The following features

are included on your saw to help reduce the

hazard of kickback; however, such features

will not totally eliminate this dangerous reac-

tion. As a chain saw user, do not rely only on

safety devices. You must follow all safety

precautions, instructions, and maintenance

in this manual to help avoid kickback and

other forces which can result in serious

injury.

S Reduced--Kickback Guide Bar, designed

with a small radius tip which reduces the

size of the kickback danger zone on the

bar tip. A Reduced--Kickback Guide Bar

has been demonstrated to significantly re-

duce the number and seriousness of kick-

backs.

S Handguard, designed to reduce the

chance of your left hand contacting the

chain if your hand slips off the front handle-

bar.

S Position of front and rear handlebars, de-

signed with distance between handles and

“in-line” with each other. The spread and

“in-line” position of the hands provided by

this design work together to give balance

and resistance in controlling the pivot of

the saw back toward the operator if kick-

back occurs.

WARNING: DO NOT RELY UPON

ANY OF THE DEVICES BUILT INTO YOUR

SAW. YOU SHOULD USE THE SAW

PROPERLY AND CAREFULLY TO AVOID

KICKBACK. Reduced-- kickback guide bars

and low-- kickback saw chains reduce the

chance and magnitude of kickback and are

recommended. Your saw has a low kick-

back chain and bar as original equipment.

Repairs on a chain brake should be made by

an authorized servicing dealer. T ake your

unit to the place of purchase if purchased

from a servicing dealer, or to the nearest au-

thorized master service dealer.

S Tip contact in some cases may cause a

lightning fast reverse REACTION, kicking

the guide bar up and back toward the oper-

ator.

S Pinching the saw chain along the top of the

guide bar may push the guide bar rapidly

back toward the operator.

S Either of these reactions may cause you to

lose control of the saw which could result

in serious injury. Do not rely exclusively

upon the safety devices built into your saw.

CHAIN BRAKE

S Chain brake, designed to stop the chain in

the event of kickback.

WARNING: Your chain saw is

equipped with a chain brake that is designed

to stop the chain immediately if you get a

kickback. The chain brake reduces the risk

of accidents, but only you can prevent them.

DO NOT ASSUME THAT THE CHAIN

BRAKE WILL PROTECT YOU IN THE

EVENT OF A KICKBACK.
