SAFETY RULES

Always disconnect

WARNING

spark plug wire and place wire where it cannot contact spark plug to prevent accidental starting when setting up, transporting, adjusting or making repairs except carburetor adjustments. Because a chain saw is a high-speed woodcutting 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

Read this manual carefully until you com-

pletely understand and can follow all safety rules, precautions, and operating instructions before attempting to use the unit. Restrict the use of your saw to adult users

who understand and can follow safety rules, precautions, and operating instructions found in this manual.

Safety Shoes

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-fogging, vented goggles or face screen; an approved safety hard hat; and sound barriers (ear plugs or mufflers) to protect your hearing. Regular users should have hearing checked regularly as chain saw noise can damage hearing. Secure hair above shoulder length. Keep all parts of your body away from the

chain when the engine is running. Keep children, bystanders, and animals a

minimum of 10 Meters away from thework area. Donot allow other people or animals to be near the chain saw when starting or operating the chain saw. Do not handle or operate a chain saw

whenyouare 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.

Safety Hat

Eye Protection

Heavy Duty Gloves

Safety Chaps

Carefully plan your sawingoperation in ad-

vance. Donot 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

Donot operate a chain saw with one hand.

Serious injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use. Operate the chain saw only in a well-venti-

lated outdoor area. Do not operate saw from a ladder or in a

tree, unless you are specifically trained to do so. 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. Do not put pressure on the saw at the endof

the cut. Applying pressure can cause you to lose control when the cut is completed. Stop the engine before setting the saw

down. Do not operate a chain saw that is dam-

aged, improperly adjusted, or not completely and securely assembled. Always replace bar, chain, hand guard, or chain brake immediately if it becomes damaged, broken or is otherwise removed. With the engine stopped, hand carry the

chain sawwith 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

Have all chain saw service performed by a

qualified service dealer with the exception of the items listed in the maintenance sectionof this manual. For example, if improper tools are used to remove or hold the flywheel whenservicingtheclutch, structuraldamage to the flywheel can occur and cause the flywheel to burst. Make certain the saw chain stops moving

when the throttle trigger is released. For correction, refer to CARBURETOR ADJUSTMENTS. Never modify your saw in any way. Use

only attachments supplied or specifically recommended by the manufacturer. Keep the handles dry, clean, and free of oil

or fuel mixture. Keep fuel and oil caps, screws, and fas-

teners securely tightened. Use only JonseredRaccessories and re-

placement parts as recommended.

HANDLE FUEL WITH CAUTION

Do not smoke while handling fuel or while

operating the saw. Eliminate all sources of sparks or flame in

the areas where fuel is mixed or poured. There should be no smoking, open flames, orworkthat could cause sparks. Allow engine to cool before refueling.

Mix and pour fuel in an outdoor area on bare

ground; store fuel in a cool, dry, well ventilated place; and use an approved, marked container for all fuel purposes. Wipe up all fuel spills before starting saw. Moveat least 10 feet (3 meters) from fuel-

ing site before starting engine. 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. Store the unit andfuel in anarea wherefuel

vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.

KICKBACK

Avoid kickback which

WARNING

can result in serious injury. backward, upward orsudden forward motion of the guide bar occurring when the saw chain near the upper tip oftheguide barcontacts any object such as a log or branch, or when the wood closes in and pinches the sawchain in the cut. Contacting a foreign object in the wood can also result in loss of chain saw control.

Rotational Kickback

moving chain contacts an object at the upper 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 toward the operator.

Pinch-Kickback

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 sawto move in theopposite direction of the chain rotation. The saw is driven straight back toward the operator.

Pull-In

contacts a foreign object in the wood in the cut along the bottom of the guidebar andthe sawchainis suddenlystopped. This sudden stopping pulls the saw forward and away fromtheoperatorand could easily cause the operator to lose control of the saw.

Avoid Pinch--Kickback:

Be extremely aware of situations or obstruc-

tions that can cause material to pinch thetop of or otherwise stop the chain. Do not cut more than one log at a time.

Do not twist the saw as the bar is with-

drawn from an undercut when bucking.

Avoid Pull--In:

Always begin cutting with the engine at full

speed and the saw housing against wood. Use wedges made of plastic or wood.

Never use metal to hold the cut open.

REDUCETHECHANCEOF KICKBACK

Recognize that kickback can happen.

With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents. Never let the moving chaincontact any ob-

ject at the tip of the guide bar. 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. Keep your saw chain sharp and properly

tensioned. A looseordull chain canincrease the chance of kickback occurring. Follow manufacturer’s chain sharpening and maintenance instructions. Checktension at regular intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after tensioning the chain. Beginand continue cutting at full speed. If

the chain is moving at a slower speed, there is greater chance of kickback occurring. Cut one log at a time.

Use extreme caution when re-entering a

previous cut. Do not attempt cuts starting with the tip of

the bar (plunge cuts). Watch for shifting logs or other forces that

could close a cut and pinch or fall into chain. Use the Reduced--Kickback Guide Bar

and Low--Kickback Chain specified for your saw.

MAINTAIN CONTROL

Stand to the left of the saw

Never reverse hand positions

Symmetrical Guide Bar

Elbow locked

Thumb on underside of handlebar

Keep a good, firm gripon the saw with both

hands when the engine is running and don’t let go. A firm grip will help youreduce kickback and maintain control of the saw. Keep the fingers of your left hand encircling and your left thumb under the front handlebar. Keep your right hand completely around the rear handle whether your are right handed orleft handed. Keep your left arm straight with the elbow locked. 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. Stand with your weight evenly balanced on

both feet. Stand slightly to the left side of the saw to

keep your body from being in a direct line with the cutting chain. Do not overreach. You could be drawn or

thrown off balance and lose control of the saw. Donot cut above shoulder height. It is diffi-

cult to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES

The following features

WARNING

are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this dangerous reaction. 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.

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 reduce the number and seriousness of kickbacks.

Reduced Kickback Symmetrical Guide Bar

Small Radius Tip

Low--Kickback Chain, designed with a

contoured depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cutter.

Low-Kickback Chain

Handguard, designed to reduce the

chance of your left hand contacting the chain if your hand slips offthe front handlebar. 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 kickback occurs.

WARNING

ANY OF THE DEVICES BUILT INTOYOUR 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 kickback chain and bar as original equipment. Repairs on a chain brake should be made by an authorized servicing dealer. Take your unit to the place of purchase if purchased from a servicing dealer, or to the nearest authorized master service dealer.

Tip contact in some cases may cause a

lightning fast reverse REACTION, kicking the guide bar up and back toward the operator. Pinching the saw chain along the top of the

guide bar may push the guide bar rapidly back toward the operator. Either of these reactions maycause youto

lose control of the saw which could result in serious injury. Do not rely exclusively uponthesafety devices built into your saw.

Contoured Depth Gauge

Elongated Guard Link Deflects Kickback Force And Allows Wood To Gradually Ride Into Cutter

DO NOT RELY UPON

Large Radius Tip

CHAIN BRAKE

Chain brake, designed to stop the chain in

the event of kickback.

Your chain saw is

WARNING

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.
