SWear protective gear. Always use steeltoed 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 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.

SKeep all parts of your body away from the chain when the engine is running.

SKeep 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.

SCarefully plan your sawing operation in advance. 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

SDo not 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.

S Operate the chain saw only in a well-venti- lated outdoor area.

SDo not operate saw from a ladder or in a tree, unless you are specifically trained to

do so.

SMake 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.

SDo 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.

SDo not operate a chain saw that is damaged, 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.

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

SHave 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 flywheel to burst.

S Make certain the saw chain stops moving when the throttle trigger is released. For correction, refer to CARBURETOR ADJUSTMENTS.

S Never modify your saw in any way. Use only attachments supplied or specifically recommended by the manufacturer.

SKeep the handles dry, clean, and free of oil or fuel mixture.

S Keep fuel and oil caps, screws, and fasteners securely tightened.

S Use only JonseredR accessories and replacement parts as recommended.

HANDLE FUEL WITH CAUTION

SDo not smoke while handling fuel or while operating the saw.

SEliminate 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 engine to cool before refueling.

3

SMix 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.

SMove at least 10 feet (3 meters) from fueling 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.

SStore 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 contacts 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 object in the wood can also result in loss of chain saw control.

SRotational Kickback can occur when the 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.

SPinch-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.

SPull-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:

SBe extremely aware of situations or obstructions 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:

SAlways 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.

Kickback Path

Clear the working area

REDUCE THE CHANCE OF KICKBACK

S Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.

SNever let the moving chain contact any object at the tip of the guide bar.

SKeep the working area free from obstructions 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 maintenance instructions. Check tension 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.

SBegin and 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.

SDo 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

Stand to the the saw

Never reverse hand positions

4

Elbow locked

Thumb on underside of handlebar

SKeep 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 encircling and your left thumb under the front handlebar. Keep your right hand completely around the rear handle whether

your are right handed or left handed. Keep your left arm straight with the elbow locked.

SPosition your left hand on the front handlebar 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.

SStand 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.

SDo not cut above shoulder height. It is difficult 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 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.

SReduced--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

Large Radius Tip

S 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

Contoured Depth Gauge

Elongated Guard Link

Deflects Kickback Force And Allows Wood To Gradually Ride Into Cutter

S Handguard, designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handlebar.

SPosition of front and rear handlebars, designed 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: 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 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.

S Tip contact in some cases may cause a lightning fast reverse REACTION, kicking the guide bar up and back toward the operator.

SPinching the saw chain along the top of the guide bar may push the guide bar rapidly

back toward the operator.

SEither 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

SChain 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.
