SAFETY RULESAND PRECAUTIONS

Because a chain saw is a high-speed wood-cutting tool, special safety precautions must be observed to reduce the risk of personal accidents. Careless or improper use may cause serious injury.

: WARNING! :_:

A. KNOW YOUR SAW

1 Read your Owner's Manual carefully until you

completely understand and can follow all

safety rules and operating instructions before

attempting to operate the unit. : . _i

:2. Restrict the use of your saw to adult users

who Understand and follow the safety rules,

....precautions, and operating instructions

B. PLAN AHEAD

Wear personal protective gear. At- ways use steel-toed safety foot-

wear with nomsliP soles snug-

.......: fitting clothing :with reinforced

cutting resistant inserts; heavy-duty non'slip

, gloves; appropriate eye protection such as non-

fogging; vented goggles or face screen; an ap-

: ::proved safety hardhat, and sound barriers I ear

- = . plugs or mufflers to protect your: hearing. Regular users should have hearing _hecked regularly, as

:"chain saw noisemay damage hearing. ' "

' 2. Keepchildren, bystanders, and pets out of the

....work area.:Do not allow other people tobe near

::'the chain saw when starting or operating'the chain

saw_:

3. Do not handle or operate a chain saw when you are fatigued, ill, or upset; or if you havetaken

.i :alcohol, drugs or medication. You must be in

good physical conditionand mentally aiert. 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.

4. Do not attempt to use your saw during bad weather conditions such as strong wind, rain, snow, etc., or during darkness.

5. Plan your sawing operations carefully in ad-

vance. DO not start cutting until you have a ctear

' iw0rkarea, secure footing, and if you are felling

•trees, a planned retreat path. :

GUARD AGAINST KICKBACK ..... ,

Kickback can lead to dangerous loss of control of

the saw and possiblY cause serious personal in- 1.

jury. Kickback isthe upwardand backward motion of the guide bar that occurswhen the movingchain con- 2. tacts an object atthe tip oftheguide bar.

To reduce the hazard of kickback:

1. Hold the saw firmly with both hands. Left hand on front handle barl right hand on rear handle

whether you are right-handed or left-handed.

Never use the saw with one hand .......

2. Do not overreach.

3. Do not let the tip of theguide bat contact the ground, another log, branch, Or any other

obstruction.

5. Cut one log atatime.

6. Use extreme caution when. re-entering a pre-

vious cut.

.7. Donot attempt plunge cuts .....

8. Watch for shifting logs' or other forces that

could close a cut and pinch the chain.

9. DO not cut above shoulder height.

10. Follow manufacturer's chain sharpening

and maintenance instructions. Keep the

chain properly tensioned. Check tension at reg- ular intervals with the engine stopped, never

,,, with the engine, running,-Make: Sure the bar

clamp nuts are secure!y:tightened after !ension-

,, .ingthe chaio.. :.,_ .

11. _Use. the Guard Link. Chain and.. Lo-Kick® Guide Bar designed foryour saw to reduce the

hazard of kickback. .......... -

D. AVOID REACTIVE FORCES _ .

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

by :contacting a foreign object in thewood. This results in a reversal of the chain force used to cut

wood and causes the saw tomove inthe opposite di-

•rection Ofchain rotation, resulting in loss of control and possible seriouspersonal injury.

To avoid Pushback:

1. Be extremely aware of situations or obstruc- tions that may cause material to pinch the top of or otherwise stop the chain.

: 2. Do not cut morethan one log at a time.

3. Do not twist the saw as the bar iswithdrawn _ from an under-cut when bucking.

To avoid Pull-In: •

Always begin cutting with the engine at full

throttle and the spike against the wood.

Use wedges made of plastic, wood, or light

alloy (never of steel or iron) to hold the cut open.

E. HANDLE FUEL WITH CAUTION ....

1. Eliminate all sources of sparks or flame in the areas where fuel is mixed, poured, or stored.

There should beno smoking, open ftames, or work that could cause sparks:

2. Mix, pour and store fuel in a well-ventilated area, on bare ground, and in an approved,

marked container.

3. Wipe up all spilled fuel before starting your

saw.

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

5 Do not smoke while handling fuel or while

operating the saw.

6. Turn the engine off and let your saw cool be-

fore removing the fuel tank cap and refueling the unit.

F. OPERATE YOUR SAW SAFELY

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

improperly adjusted, or not completely and securely assembled.

2. Do not operate the saw from a ladder or in a

•tree,

3. Position all parts of your body away to the side of the saw chain protrudingto the leftofcut when

the engine is running.

4. Cut wood Only. Do not use to pry or shove away

limbs, roots or other objects.

5. Make sure the chain will not make contact be-

fore starting the engine. Never try to start the

saw when the guide bar is in aCutor kerr.

6. Use extreme caution when cutting small size

brush and saplings. Slender materialmay catch the saw chain and be whipped toward you or pull you off balance.

7. 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.

8. Do not put pressure on the saw at the end of a cut. This could cause you to lose control when

the cut is completed.

9. Stopthe engine before setting the saw down.

G, MAINTAIN YOUR SAW :IN GOOD

WORKING ORDER

1. Have all chain saw service performed by your authorized service dealer center, otherthan the

items listed in the maintenance section of this

manual.

2. Keep fuel and oil caps, screws and fasteners securelytightened.

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. If it does not, refer topage 22 for correctcarburetor idle ad-

justment instructions.

5. Stop the saw if the chain strikes aforeign ob-

ject. Inspectthe unitand repair orreplace parts as

necessary.

ments.

Never modify your saw in any way. Use Only attachments supplied or specifically recom- mended by Sears.

H. CARRY AND YOUR SAW

SAFELY

1. Hand carry the unit with the engine stopped, the Muffler away from your body, and the Guide

Bar and Chain to the rearcowered preferably with

a scabbard,

2. Before transporting in anyvehicle or storing in

any enclosure, allow your saw to cool com-

pletely, cover the bar and chainand properly se- cureto avoidturnover, fuel spillage or damage.

3. Drain oil and fuel tank before storing for more

than 30 days.

4. Store ina dry area out of the reach of children and away from where fuel vapors can reach an

open flame from hotwater heaters, furnaces, etc.

Exposure to vibrations through prolonged use of chain saws may produce Whitefinger disease (Raynaud's

phenomenon). This phenomenon reduces the hand's ability to feel and regulate temperature, produces

numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis. An

anti-vibration system designed to reduce engine vibration is available on many Sears models and is

recommended for those using chain saws on a regular or sustained basis.

An anti-vibration system does not guarantee the avoidance of Whitefinger disease, Continual and regular

users should monitor closely their use of chain saws and physical condition.

E. CHAIN TENSION

• 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,

• Chain tension is correct when the chain:

--can be lifted about 1/8" from the Guide Bar

at a point near the middle of the bar, and

•--will move freely around the bar.

• The chain stretches during use, especially

when new. Check tension:

:-- each time the saw isused

w more frequently when the chainis new J as the chain warms upto normal operatingtem-

perature

• The Bar Clamp Nuts must be slightly loose to

tension the chain correctly.

1. Hold the tip of the Guide Bar up and turn the Adjusting Screw. just until the,chain does not sag beneath the Guide Bar, Figureg.

'NOTE: Turn screw clockwise to tighten ten-

sion; Turn screw counterclockwise to loosen

tension .....

• Your chain saw is powered by a two-cycle

engine which requres a fuel mixture of regu-

_lar gasoline anda high quality engine oil spe-

cially made for 2-cycle, air-cooled engines. The internal design of the 2-cycle engine re-

quires lubrication of moving parts. Lubrica- tion is provided when you use the recom-

...... mended mixtureof gasoline and oil, .

• Gasoline must be iclean and not over two months old. After :a sl_ort period of itime,

: 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 oil in the mixture will =fou! the

........ Spark plug.

........... --Too little oil will cause the engine to over-

heat resulting in damage,

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

try to mix fuel directly in the fuel tank.

U'XTURE:

Figure 10

1. USE THE FOLLOWING FUEL MIXTURES:

2. DO NOT USE:

• BIA Oil (Boating Institute of America)

--Does not have proper additives for air- cooled, 2-cycle engines and could cause

damage.

• AUTOMOTIVE OIL-

- Does not have proper additivesfor 2-cycle engines and couldcause damage.

• GASOLINE CONTAINING ALCOHOL-

m Attractswater causing corrosiondamage.

3. HOW TO MIX FUEL

4. IMPORTANT POINTS

a. Pour one-half of the gasoline into an ap-

proved, marked container. Do not try to mix

oil and gasoline directly in the fue! tank.

b. Add entire measure of 2*cycle Engine Oil. c. Mix.

d. Add remainder of gasoline. e. Mix thoroughly for one minute.

Figure 11

G. BAR AND CHAIN OIL

• 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,

--Lack of oil will quickly ruin the bar and

chain.

--Too little oil will cause overheating shown

by smoke coming from the chain and/or discoloration of the guide bar rails.

• Use Sears Bar and Chain Lubricant #71-36554 or clean SAE 30W oil.

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

small amount of Diesel Fuel #1 or Kerosene.

Bar and chain oil must be free flowing for the oil system to pump enough oil .for adequate

lubrication.

ao Eliminate all sources of sparks or flame in

the areas where fuel is mixed, poured, or

stored. There should be no smoking, open

flames or work that could cause sparks.

b. Mix, pour and store fuel in an approved,

marked, container and in a well-ventilated area. Gasoline vapors are harmful to your

health and are a serious fire hazard. Use a fun- nel or spout when pouring fuel.

c. Avoid overfilling the fuel tank. Allow3/4 inch

for ex pansion. Tighten Fuel Cap securely. Fig-

ure 11.

d. Wipe up all fuel spills. Wipe off any fuel spil-

led on the saw. Completely dry the saw before using.

e. Move at least 10 feet (3 meters) away from

fueland fueling site before starUng the en-

gine.

1. USE THE FOLLOWING:

30°F or above Lubricant -- undiluted. 30°F - 0° F --

95% lubricant to 5% Diesel

Fuel #1 or Kerosene.

Below 0°F

90% lubricant to 10%

Diesel Fuel #1 or Kerosene.

2. HOW TO FILL THE OIL TANK

a. Stop the engine. b. Turn saw on its side with oil cap up. Figure

12.

c. Loosen cap slowly and wait for pressure in

the tank to be released before removing the cap.

d. Fill the oil tank. e. Replace the oil cap securely.

FILLTHE TANK EACH

THE FUEL TANK IS FILLED

Figure 12

3. IMPORTANT POINTS TO REMEMBER

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

tank to ensure there wilt be sufficient oi! for the chain whenever you start and run the

saw.

The saw will use about 112 tank of chain oil

for each tank of fuel mixture. If tess oil is used, check for a plugged oil hole in the guide bar. ; •

It is normal for a small amount of oil to ap- pear under the saw after the engine stops.

This is due to oil draining from the bar and

chain when not in use.

USING YOUR SAW .... i

A. CONTROL DEVICES

Understanding the control devices on your saw

is an important part of learning how to properly

and safely operate the unit. Figure 13. _

1: The ignition Switch is a!oggte switch which

is moved up for the "Start" position and mov- ed down for the' "Stop" i_osition.

2. The two-position Choke helps to start the saw by controlling the air flow to the fuel

system.

3. The Trigger accelerates and controls the speed of the engine and is designed to be

used with the Throttle Lock.

prevents the Trigger from becoming accident- ly engaged. The Throttle Lock must be press-

ed before the Trigger can be activated.

5;The Throttle Detent Button holds the Throttle

Lock and Trigger in position while the engine is being started. Release the Throttle Detent Button after the engine is started by lightly squeezing the trigger.

B. STARTING INSTRUCTIONS

1. IMPORTANT POINTS

a. Push down onthe throttle lockout, squeeze

the trigger, press and hold down the throt-

tle detent button, then slowly release the trigger.

b. Engage choke according to "Starting In-

structions" below.

c. Hold saw firmly with the saw chain free to

turn without contacting any object. Figure

14.

d. Pull starter rope quickly, using no more

than 15-18 inches of rope per pull. Using the

full length of the starter,rope may cause it to

break, Do not let the starter rope snap back.

Hold the handle and let the rope rewindslowly.

e. Release the throttle detent button after en-

gine starts, allowing the engine to idle. The

chain must not move when the engine runs at idle speed, if correction is required_' refer to

CarburetorAdjustments, page 22.

C. CONTROLLING KICKBACK ........

Kickback isa dangerous reaction thatcancause serious personal injury. Carefully study this man-

ual before you make the first cut with your new

saw. "Youmust understand what causes kickback,

.how you can reduce the chance of kickback, and how :you can remain in the best control of the saw if

kickback does occur.

1. _WHAT CAUSES KICKBACK :

Kickback can occur when the moving chain

- __contacts an object at the tip or nose of the

guide bar. This contact causes the chain to dig

_-_.into the object and stops the chain for an instant. The result is a lightning fast, reverse reaction

which kicks the saw tip up and back toward the operator. The operator can lose control of the saw and the cutting chain can cause serious personal

injury if it contacts any part of the body.

Figure 15

AVOID OBSTRUCTIONS

2. REDUCETHE CHANCE OF : :,:

KICKBACK

a. Recognize that kickback can happen. By

understanding and knowing about kickback,

you are better equipped to deal with an occur-

rence.

b. Never let the moving chain contact any ob-

ject at the tip ofthe guide bar. Figure 15.

c. Keep the working area free from obstruc-

tions such as other trees, branches, rocks, fences, stumps, etc. Figure 16. Eliminate or

avoid any obstruction that your saw chain could hit while you are cutting through a par-

kickback and help you maintain controlof the

saw. Keep the fingers ofyour lefthand encirc-

ling and your left thumb under the front han-

dlebar. Keep your right hand completely

around the rear handle whether you are right

:handed or/eft handed. Keep your left arm

straight with theelbow locked.

b. Position your left hand on the front han-

dlebar so it is in a straight line with your

right hand on the rear handle. Figure 17. Never reverse rightand lefthand position.

keep your body from being in a direct line

with the cutting chain; Figure 17.
