SPECIAL SAFETY SECTION

GUARD AGAINST KICKBACK

Kickback is a dangerous reaction that can lead to

serious injury. Do not rely only on the safety

devices provided with your saw. As achain saw

user, you must take special safely precautions to help

keep your cutting jobs free from accident or injury.

A KICKBACK WARNING

Kickback can occur when the moving chain contacts an object atthe upperportionof the tip ofthegulde bar

or when the wood doses inand pinches the saw chain

inthe cut. Contact at the upper portion of the tip of the

guidebarcan causethechaintodig into theobject and

atop the chain for an Instant. The result is a lightning

fast, reverse reaction which kicks the guide bar up and back toward the operator, ff the saw chain ispinched

along the top of the guide bar, the guide bar can be driven rapidly back toward the operator. Either of these re=icti0ns Can Cause io_,sof saw control which

can result in serious injury.

KICKBACK PATH

REDUCE THECHANCE OF KICKBACK

1. ReCognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to

_ccidents.

2. Never let the moving chain contact anyobject atthe

tip of the guide bar. Figure 1.

3. Keep the working area free from obstructions such as other trees, branches, rocks, fences,

stumps, etc. Figure 2. Eliminate or avoid any

- obstruction that your saw chain could hit while you

are cutting through a particular log or branch.

4. Keep your saw chain sharp and properly ten- sioned. Followmanufacturer's chain sharpeningand maintenance instructions.Check tension at regular intervalswiththeenginestopped,neverwiththeengine

running.Make sure the bar clamp nuts are securely

tighter,ed after tensioning the chain. A _ or dull chain can increase the chance of kickback to occur.

5. Begin and continue cutting ait full throttle. If the

chain is moving at a slower speed, there is greater chance for kickback to occur.

6. Cut only one log at a time.

7. Use extreme caution when re-entering a previous cut.

8. Do not attempt plunge cuts.

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

10. Use only the Reduced-Kickback Guide Bar and

Low-Kickback Chain specifiedforyoursaw.

MAINTAIN CONTROL

1. Keep agood firl_ grip on the saw with both hands when the engine is running and don't let go. Figure 3. A firm.grip can neutralize kickback and help you 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

you are right handed or lefthanded. Keep your left

arm straight with the elbow locked.

2. Position your left hand on the front handlebar soit

isIn a straight line with your right hand on the rear

handle when making bucking cuts. Figure 3. Never

reverse right and left hand positions during any lype

ofcutting.

3. Stand with your weight evenly balanced on both feet.

4. Stand slightly to the left side of the saw, to keep

your body from being in a direct line with the

cutting chain. Figure 3.

5. Do not overreach. You could be drawn or thrown

off balance and lose control of the saw.

6. Do not cut above shoulder height. It isdifficultto

maintain control of the saw above shoulder height.

instructionsbeforeattemptingtooperatethe unit.

2. I_estdct the use o'fyour sawto adult userswho under-

stagd and follow the safety rules, precautions, and

operating instructionsinthismanual.

PLAN AHEAD

1. Wear personal protective gear. Figure 4, Alwaysuse

steel-toedsafetyfoQtwearwithnon,slipsoles;snug-fitting clothing;heavy-dutynon-slipgloves;eye protectionsuch

as norvfogging, vented goggtes or face screen; an ap- provedsafetyhardhat,and soundbarriers-- earplugsor mufflersto protect your hearing. Regular users should have headng checked regularlyas chain saw noisecan

damage hearing.

2. Keep children, bystanders, and animals out of the

work area-- aminimum of 30 feet (10 meters). Donot allowother people or animals to be near the chain saw

when startingor operatingthe chain saw.

3. 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. Chaip 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.

_AVOID REACTIVE FORCES

Pinch-Kickback and Pull-in occur when the chain suddenly stopped by being pinched, caught, or

contacting a foi_ign object in the wood. Thisresultsi reversalofthechainforceusedtocutwoodand causesthes

Pull-inpuffs the saw awayfromtheoperator.Eitherreactk canresult inloss ofcontrol and possible serious inju_.

To avoid Pinch-Kickback:

1, Be extremely aware of situations or obstructk

that can cause material to pinch the top of or otf wise stop the chain.

2. Do not cutmore than one log at a time.

3. Do not twist the saw asthe bar iswithdrawnfrom under-cut when bucking.

To avoid Pull-in:

1. Always begin cutting with the engine at full thin and the spur against the wood.

2. Use wedges_nade ofplastic orwood, (never of me

toholdthe cut open.

HANDLE FUEL WITH CAUTION

1. Eliminate allsources of sparks or flame in the ar

where fuel is mixed, poured, or stored. There sh( be no smoking, open flames, orworkthat couldca

sparks."

2. Mix and pour fuelin an outdoor area, on bare grou store fuel ina cool, dry,well-ventilated place; and an approved, marked container for all fuel purpo.,

3. Wipe up all spilled f_el before starting your.,

4. Move at least 10 feet (3 meters) away from fuel fueling site before starting the engine.

5. Oo not smoke while handling fuel or while opera the saw.

6. Turn the engine off and let your saw cool in a I

combustible area, noton dryleaves,straw,paper: Slowlyremove thefuel tank cap and refuelthe unit.

7. Store tool and fuel in an area where fuel vapors

not reach sparks or open flames from water hea electric motors or switches, furnaces, etc.

OPERATE YOUR SAW SAFELY

1. Do not operate a chain saw that is damaged, im-

properly adjusted, or not completely and securely assembled.

2. Operate the chain saw only in outdoor areas.

3. Do not operate the saw from a ladder or in a tree.

4. Position all parts of your body to the left of cut and

away from the saw chain when the engine is running.

5. Cut wood only. Do notcutmetal;plastics,masonry,'non-

woodbu,ding materials, etc.Donotuse yoursaw to pryor shove away limbs,rootsor other objects.

6. Make sure the chain will not makecontact with anyob-

Jectwhile startingthe engine. NeverWto stadthe saw

when the gu'rdebar is in a cutor kerf.

7. Use extreme caution when cutting small size brush

and saplings. Slender material can catchlthe saw chain and be whipped toward you or pull you off

balance.

8. Be alert for springback when cutting a limb that is

under tension so you will not be struck by the limb or

saw when the tension in the wood fibers is released.

9. Do not put pressure on the saw st the end of a cut. This can cause you to lose control when the cut is

completed.

10. Stop the engine before setting the saw down.

MAINTAIN YOUR SAW IN GOOD WORKING ORDER

1. Have all chain saw service performed by your Sears Service Center withthee00cept_oftheitems listedinthe

maintenance section of this manual. For example, if improper tools are used to removeor hold the flywheel

when servicing the clutch, structural damage to the

flywheel c_ occurand cause theflywheelto burst.

2. Keep fuel and oil caps, screws and fasteners

securely tightened.

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

4. Make certain the saw chain stops moving when the throttle trigger is released. Forcorrection,refertopage

24 for carburetor idleadjustmentinstructions.

5. Stop the saw if the chain strikes a foreign object. In-

sPect the unitand repair or replace parts as necessary.

6. Disconnect the spark plug before performing any

maintenance except for carburetor adjustments.

7. Never modify your saw in any way. Use only attach- ments supplied or specifically recommended by the

n_nufacturer.

8. Always replace the handguard immediately if it

becomes damaged, or broken or is otherwise removed.

9. Keep vibrstion isolators in good condition. Peri,odically inspectisolatorsfortears,ripsorseparation ofthe'rubber

portionfromthe metal mountings. Have your Sears Ser-

vice Center replace the isolatorsifwornor damaged, if Vibrationincreasesorifmountsdevelopanoutofroundor

swollenshape from exposure to gasolineand/or oil.it is recommendedthat_ isolatorsbe replaced when a failure

toone occurs.

CARRY AND STORE YOUR SAW SAFELY

1. Handcarry the unit with the engine stopped, the Muffler away from your body, and the Guide Barand

"Chain to the rear covered preferably with a scabbard.

2. Before transporUng in any vehicle or storing in any

enclosure, allow your saw to cool completely, cover

the bar and chain and properly secure to avoid turnover, fuel spillage or damage.

3. Empty the fuel tank before storing the tool. Use up fuel left in the carburetor by starting the eng-

ine and letting the engine run until it stops.

4. Store in a dry area out of the reach of children and

away from where fuel vapors can reach sparks or an open flame from hotwater heaters,furnaces,etc.

SAVE THESE INSTRUCTIONS

NOTE: Exposure to vibrations through prolonged useof

chain saws may produce Whiteflnger disease (Raynaud's phenomenon). This phenomenon

reduces the hand's ability to feet and regulate

temperature, produces numbness and burning sensations and can cause nerve and circulation

damage and tissue necrosis. An anti-vibration system designed to reduce

engine vibration is recommended for those using chain saws on a-regular or sustained basis and is provided on this saw. However, an antivibration system does not guarantee the avoidance of

•Whitefingerdisease. Continual and regular users must monitor closely their use of chain saws and

physical condition.

Notice: Refer to the Code of Federal Regulations, Section

1910.266(5); 2.5.1 of American National Standard

Safety Requirements for Pulpwood Logging, ANSI

03.1-1978; and relevant state safety codes when

using a chain saw for loggingpurposes.

• Correct chain tension is very important:.

--a loose chain will wear the bar and itself.

--a loose chain can jump off the bar while

you are cutting.

--a tight chain can damage the saw and/or

break.

• The chain stretches during use, especially when new. Check tension:

each time the saw is used

more frequently when the chainisnew

as the chain warms up to normal operatingtem- perature

• Chain tensioning procedure:

1. Holdthe t{poftheGuideBarupandturntheAdjusting Screwjustuntilthe chain does notsag beneaththe Guide Bar.Figure14.

NOTE: Turn s_:rew clockwise to tighten ten- sion. Turn screw counterclockwise to loosen tension.

_i. Store tool and fuelin an area where fuelvapors

cannot reach sparks or open flames from water

heaters, electric motors or switches, furnaces, etc.

2, FUEL MIXTURE

• Yourchainsawispowered byatwo.cycleepgine

which requires afuel mixture of regular unleaded gasoline and a high quality engine oil specially made for2-cycle, air-cooled engines. The internal

design of the 2-cycle engine requires lubrication'of

• "Gasoline must be clean _and not over two months old. After a short period of time, gasoline .begins _to chemically break down

and will form compounds that can cause hard starting and damage in 2-cycle engines.

• The correct measure of gasoline to oil is very important.Too much oit in the mixture •will

foul thespark plug.

I_UTION.:_J Too little oil will cause the engine to

overheat and seize.

• Mix the fuel thoroughly in a container since gasoline and oil do not readily combine. Do not

trytomix fuel directly in the fuel tank°

• AUTOMOTIVE OIL-

•_ Does not have proper additivesfor 2-cycle enginesand cancause damage.

5. HOWTO MIX FUELAND RLL TANK

a, Pour 1/2gallonof regular unleaded gasoline

intoanapproved, marked container.Do nottry

b. Add entiremeasurez)f engine oil.

G, PAR AHD'cHA!" LUBB!¢ANi;

• The guide bar and cutting chain require con- tinuous lubrication in order to remain in

operating condition. Lubrication is provided by the automatic oiler system when the oil

tank is kept filled.

-- Lackof lubricant will quickly ruin the bar and chain.

--Too little lubricant will cause overheating shown by smoke coming from the chainand/or

discolorationoftheguide bar rails,

Use Sears Bar and Chain Lubricant #71-36554 - I qt. or #71-36556 - 1 gal. or clean SAE 30W oil.

In f_eezing weather, oil will thicken, making it necessary to thin bar and chain oil with a small

b. Fill the oil tank each time you refill the fuel

tank to ensure there wiltbe stJfficientoilfor the chainwheneveryou startand runthe saw.

c. The saw will use about 1/2 tank of chain oil for

each tank of fuel mixture. If less oil is used, checkfor a pluggedoilholeinthe guidebar.

d- it is normal tor a small amount of oil to appear

under the saw after the engine stops. This is

due to oil drainingfrom the bar and chainwhen not inuse.
