SAFETY RULES

WARNING: Always disconnect

spark plug wire and place wire where it cannot 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 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

S Read this manual carefully until you completely understand and can follow all safety rules, precautions, and operating instruc-

tions before attempting to use the unit.

SRestrict the use of your saw to adult users who understand and can follow safety

rules, precautions, and operating instructions found in this manual.

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 30 feet (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.

SDo 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.

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

SDo not operate saw from a ladder or in a tree.

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.

SWith 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.

SMake certain the saw chain stops moving when the throttle trigger is released. For correction, refer to CARBURETOR AD-

JUSTMENT.

S Never modify your saw in any way.

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

SKeep fuel and oil caps, screws, and fasteners securely tightened.

SUse only Poulan PRO 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.

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.

STurn 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

3

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 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.

SDo not twist the saw as the bar is withdrawn 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

there is greater chance of kickback occurring.

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).

SWatch for shifting logs or other forces that could close a cut and pinch or fall into chain.

SUse the Reduced--Kickback Guide Bar and Low--Kickback Chain specified for your saw.

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. When cutting a branch, do not let the guide bar contact

branch or other objects around it.

SKeep 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 nuts are securely tight-

ened after tensioning the chain.

SBegin and continue cutting at full speed. If the chain is moving at a slower speed,

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.

SDo 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 danger. 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 when tested in accordance with safety requirements for gasoline powered chain saws as set by ANSI B175.1.

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 has met kickback performance requirements when tested on a representative sample of chain saws below 3.8 cubic inch displacement specified in ANSI B175.1.

SFront Hand Guard, 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.

CHAIN BRAKE AND CKA ANGLE

SChain Brake, designed to stop the chain in the event of kickback.

WARNING: WE DO NOT REP-

RESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. Kickback is a lightning fast action which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may

push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. 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.

STip contact in some cases may cause a lightning fast reverse REACTION, kicking guide

bar up and back toward 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 devices built into your saw.

WARNING: Computed kickback

angle (CKA) listed on your saw and listed in the CKA table below represents angle of kickback

your bar and chain combinations will have when tested in accordance with CSA (Canadian Standards Association) and ANSI standards. When purchasing replacement bar and chain, considerations should be given to the lower CKA values. Lower CKA values represent safer angles to the user, higher values indicate more angle and higher kick energies. Computed angles represented indicate total

energy and angle associated without activation of the chain brake during kickback. Activated angle represents chain stopping time relative to activation angle of chain break and resulting kick angle of saw. In all cases lower CKA values represent a safer operating environment for the user.

The following guide bar and chain combinations meet kickback requirements of CSA Standards Z62.1, Z62.3, & ANSI B175.1 when

used on saws listed in this manual. Use of bar and chain combinations other than those listed is not recommended and may not meet the CKA requirements per standard.
