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, 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

S 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.

Pull the starter rope sharply with your right hand until the engine starts.

S Restrict the use of your saw to adult users

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

S Wear protective gear. Always use steel-

toed safety footwear with non-slip soles; snug-fitting clothing; safety chaps; heavyduty, 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.

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 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.

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 c utting until you have a clear work area, secure footing, and, if you are felling trees, a planned retreat path.

OPERATE YOUR SAW SAF ELY

S Do 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.

S Do not operate saw from a ladder or in a

tree.

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 completely and s ecurely assembled. Always replace bar, chain, hand guard, or chain brake immediately if it becomes damaged, broken or is otherwise removed.

S Hand carry saw only when engine is

stopped. Carry with muffler away from body; guide bar and chain projecting behind you; guide bar covered with a scabbard.

MAINTAIN YOUR SAW IN GOOD WORKING O RDER

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 flywheel to burst.

S Make certain the saw chain stops moving

when the throttle trigger is released. For correction, refer to CARBURETOR ADJUSTMENT.

S Never modify your saw in any way. 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 McCulloch 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 engine to cool before refueling.

S Always have fire extinguishing tools avail-

able if you should need them.

S 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.

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 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.

S Rotational 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.

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 ob-

structions 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.

ickback Path

S Begin and continue cutting at full speed. If

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

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

Stand to the left of the saw

Thumb on underside of handlebar

Never reverse hand positions

Avoid Obstructions

Clear The Working Area

REDUCE THE CHA NCE 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.

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. When cutting a branch, do not let the guide bar contact branch or other objects around it.

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 nuts are securely tightened after tensioning the chain.

Elbow locked

Thumb on underside of handlebar

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 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.

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 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. 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 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.

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 canalsobecausedby pinchingthesawchain 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. S Tip contact in some cases may cause a light-

ning fast reverse REACTION, kicking guide bar up and back toward operator.

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 c ontrol 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 repres ents 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.
