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 a chain saw

user, you must take special safely precautions to help

keep your cutting jobs free from accident or injury.

AKICKBACK WARNING

Kickback can occur when the moving chain contacts

an object atthe upperportionof the tip ofthegulde bar

or when the wood doses in and 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 is pinched

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.

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 at the

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

intervalswiththe enginestopped,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 left handed. Keep your left

arm straight with the elbow locked.

2. Position 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. Figure 3. Never

reverse right and left hand positions during any lype

of cutting.

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 is difficult to

maintain control of the saw above shoulder height.

,KNOW YOUR SAW

1. Read your Operator's Manual carefully untilyou com-

pletelyunderstandandfollowagsafetyrotes andoperating

instructionsbefore attemptingto operate the unit.

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

stagd and follow the safety rules, precautions, and

operating instructionsinthismanual.

PLAN AHEAD

1. Wear personal protective gear. Figure 4, Alwaysuse

steel-toed safetyfoQtwearwithnon,slipsoles;snug-fitting

clothing;heavy-dutynon-slipgloves;eye protectionsuch

as norvfogging, vented goggtes or face screen; an ap-

provedsafetyhardhat,and soundbarriers-- ear plugsor

mufflers to protect your hearing. Regular users should

have headng checked regularlyas chain saw noise can

damage hearing.

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

work area-- aminimum of 30 feet (10 meters). Donot

allow other 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. This resultsi

reversalofthe chainforceusedtocutwoodand causesthes

to move inthe opposite directior_of chain rotation.Pine

Kickback drives the saw straightback toward the opera

Pull-inpuffs the saw awayfromthe operator.Eitherreactk

can result 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 is withdrawn from

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 of plastic orwood, (never of me

to holdthe 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:

Slowly remove the fuel 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-

wood bu,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 isin a cut or 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 alimb 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 withthe e00cept_ 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_ occur and cause the flywheelto 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,referto page

24 for carburetor idle adjustmentinstructions.

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

sPect the unit and 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 isolatorsif worn or damaged, if

Vibrationincreases orifmountsdevelopan outofroundor

swollenshape from exposure to gasoline and/or oil.it is

recommended that_isolatorsbe replaced when a failure

to one 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 use of

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 logging purposes.

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.

• The chain stretches during use, especially

when new. Check tension:

each time the saw is used

more frequently when the chain is new

as the chain warms up to normal operatingtem-

perature

•Chain tensioning procedure:

1. Holdthe t{poftheGuideBarupandturntheAdjusting

Screw justuntilthe chain does notsag beneath the

Guide Bar.Figure 14.

NOTE: Turn s_:rew clockwise to tighten ten-

sion. Turn screw counterclockwise to loosen

tension.

2..Check the tension by lifting the chain from

the Guide Bar atthe center of the bar. Figure

15.

3. Continue turning the Adjusting Screw until

the tension is correct.

4. Holdthe tipof the Guide Barupand securely tighten

the Bar Clamp Nutswiththe Scrench.

5. Recheck tension.See Figure 15.

• 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.

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 chain and/or

discolorationof the guide 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

amount of Diesel Fuel #1 or Kerosene. Bar and

chain lubricantmust be freeflowingfortheoilsystem

to pump enough oil for adequate lubrication,

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

each tank of fuel mixture. If less oil is used,

check for a pluggedoilhole inthe 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

USING THE POWER SHARP®SYSTEM (MODEL 358.356101)

i i i| i i ii i ii ii ii i] i iii i

Model 35_.356101 is equipped with a Power Sharp®

System that will perform approximately 80% of the

sharpening necessary for t;,a saw chain. The Power

Sharp ® System utilizes a built-in gdnding stone to

sharpen the cuttertop platesand setdepth gauges. As

the built-in sharpener is used, the cutter side plates

graduallywillbe altered.Aboutevery3rd to 5thtime the

Power Sharp® Systemis used, hand filing is required

to correct the cutter side plates and depth gauges.

• Sharpen the saw chain when:

--wood chips become small and powdery.

Wood chips made by the chain should be

about the size of the teeth of the chain.

--saw cuts to one side.

--saw has to be forced through the cut.

ICAUTiON: 1Ai_ays wear -' ......y..vvu_ v,,'hOn _'''";"_

the chain. The chain can be sharp enough to cut

you, even when it is too dull to cut wood.

• Always replace the sharpening stone when

•--sparks are no longer seen at full adjust-

ment

--only 1/4 inch of stone is remaining

--stone has become cracked or damaged.

--a new chain is installed. The used stone

will be worn to the shape of the old chain

and can cause excessive wear to anew

chain. Replacement chain comes supplied

with Stone Cartridge Replacement #69099.

Refer to"Replaceor Remove the Stone and

Carrier Assembly" in this section.

• Always remove the sharpening stone if a con-

ventional chain, is-substituted for the ,Power

Sharp sChain. See instructionsforremoving the

Stone Cartridge in this section. Use replace-

ment chain #7I-3638• Foliow "ChainSha_rpeni,_g'

in the Maintenance section•

Am AUTOMATIC SHARPENING

1. Stop the engine.

2. Place the saw on asolid, flat surface and

make sure that the chain will not contact

any object.

3. Adjust the chain with correct tension. Refer to

"Chain Tension"

IMPORTANT: The chain must be tensioned

correctly for proper sharpening to occur•

!

4. Start the engine and operate athalf to three/

quarters throttle during Steps"5 through 8".

NOTE: Saw must be runningathalf to three/

quarters throttle before knob is pressed.

5. :Push the Power Sharp ® __Knob down slowly :

until fully pressed down. Figure20.

NOTE: If stone should contact chain before

knob is fully pressed down, release knob

and turn knob counterclockwise until condi-

tion does not exist. Repeat Step "5" again.

6. Turn knob slowly clockwise until sparks can

be seen as shown in Figure 20.

SPARKS ARE SEEN HERE

Figure 20

NOTE: Proper sharpening occurswhen a light

flow of sparks is seen. Improper sharpening is

shown by a heavy flowof sparks or no sparks

7. Release knob and turn one additional "click'

clockwise.

NOTE: It is important to turn the knob onl_

one "click" each time the knob is pressed.

More turns will result in making the chain dul

instead of sharp.

8. Press knob firmly against chain and hold fo=

10-15 seconds or until sparks can no long el

be seen.

9. Release knob and stop the engine.

i0. Inspect chain cutters.

Items Required:

Gloves flat file

5/32" dia. file vise

file holder screwdriver

NOTE: If abrasive materials such as rocks, nails,

sand or dirt are contacted by the chain, the side

plates should be checked more often. Damage

to the cutters caused by abrasive materials

usually results in discoloration spots where the

chrome has been worn away. Cutter side plates -

should be filed until these spots are removed.

1. Stop the engine.

2. Adjust the chain for proper tension, See "Chain

Tension:'

3. Clamp the bar in a vise to hold the chain

stead','. Do not ctamp the chain.

NOTE: Work at the midpoint of the bar, mov-

TYPES OF CUTTING

IIIHIIIIIIIIIIIIII I I III II

A. BASlC CUTTING TECHNIQUE

1. IMPORTANT POINTS.

a. Cut wood only. Do not cut metal, plastics,

masonry,non-wo_ buiiomgmatedais,et_ Donor

useyoursawto pryorshoveawaylimbs, rootsor

otherobjects.

b. Stop the saw if the chain strikes a foreign

object. Inspect the unit and repair or replace

parts as necessary.

_c. Keep the chain out of dirt and sand. Even a

small amount ofdirt will quickly dulla chain and

..... thus, increase the possibilityof kickback.

A KICKBACK WARNING

Kickbackcan occur when the moving chain contacts an

object at the upper pc rtion of the tip of the guide bar or

when the wood closes in and pinches the saw chain in

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

guide barcan cause the chain to dig into the object and

stop the chain for an instant. The resuit is a lightning

fast, reverse reaction which kicks the guide bar up and

back toward the operator, ff the saw chain is pinched

along the top of the guide bar, the guide bar can be

driven rapidly back toward the operator. Either of these

reactions can cause loss of saw control which can

result in serious injury.

2. UNDERSTAND REACTIVE FORCES

Pinch-Kickbackand Pull-in occur when the chain

is suddenly stopped bybeing pinched, caught, or

by contacting a foreign object in the wood. This

resultsin a reversalofthe chain force used tocutwood

and causesthe sawtomoveinthe Oppositedirectionof

chain rotation.Eitherreactioncan resultin lossofcon-

trql and possible serious injury.

=Pinch-Kickback

--occurs when the chain,ontopof the barissuddenly

stoppedwhen the top of the bar is usedforcutting.

--rapidly drives the saw straight back toward the

operator.

• Pull-In-

--can occur when the chain on the bottom of the

bar is suddenly stopped.

--pulls the sawrapidly forward.

- ii i ij

B. TREE FELLING TECHNIQUES

1. PLAN YOUR SAWING OPERATION CARE-

FULLY IN ADVANCE

a. Clear the work area. You need a clear area all

around the tree where youcan have secure

footing.

b. Study the natural conditions that can cause

the tree to fall in a particular direction:

1.) TheWIND directionand spe_d.

2.) The LEAN ofthe tree.

3.) WEIGHTED withBRANCHES on one side.

4.) SurroundingTREES and OBSTACLES.

c. Look for decay and rot. If the trunk is rotted,

it could snap and fall toward the operator.

3. PROCEDURE

Practicecuttingafew small logsusingthefollowing techni-

que toget the "feel" of usingyour sawbeforeyou begina

maior sawingoperation.

a. Accelerate the engine to full throttle just before

entering the cut by squeezingthe throttle trigger.

b. Begin cutting with the spur against the log.

Figure27.

-. c. Keep the engine at full throttle the entire time you

are cutting.

d. Allow the chain to cut for you; exert only light

downward pressure. If you force the cut, damage to

the bar,chain, orengine can result. "

e. Release the throttle trigger as soon as the cut is

d. Check for broken or dead branches whi(

could fall on you while cutting.

e. Make sure thereis enough room for thetree

fall. Maintain adistanceof 21/2tree lengthsfro

the nearestperson orotherobjects.Enginenoi=

can drownoutwarning call.

f. Remove dirt, stones, loose bark, hall

staples, and wire from the tree where cu

are to be made:

g. Plan to stand on the up-hill side when cl

ting on a slope.

h. Plan a,,clear retreat path to the rear ar

diagonal to the line of fall. Figure 28,

t4

2, FELLING SMALL TREES -- LESS THAN

6" IN'DIAMETER

a. If you knowthe directionof fall:

1.) Make a single felling cut on the side away

fromthe directionof fall.

2.) Cut alithe waythrough.

3.) Stop the saw, put it down, and get away

quicklyon yourplanted retreat path.

b. If you are not sure which way the tree will fall,

use the notch method described for felling

iarge trees.

A_,WARNING

DONOTCUT:

near electrical wires or buildings.

if you do not knowthe direction of tree fall.

-- at night since you will not be able to see well.

mduring bad weather _strong wind, snow, rain,

etc.

3. FELUNG LARGE TREES m6" DIAMETER

OR MORE _

The notch method is used to cut large trees. A

notch is cut on the side of the tree in the desired

direction of fall. After a felling cut is made on the

opposite sideof the tree, the tree will tend to fall

into the notch_

NOTE: If the tree has large buttress roots, re-

move before making the notch. Cut into the but-

tresses vertically, then horizontally. Figure 29.

a. Make the notchcuL Figure30.

1.) Cut the bottom of the notch first, through

1/3 of thediameter of the tree.

2.) Complete the notch by making the slant

cut.

3.) Remove the notchof wood.

b.

. C.

Make the felling cut on the opposite side of the

notch about 2" higher than the bottom of the

notch.

Leave enough uncut wood between the felling

cut and the notchto forma hinge. Figure 31.

d*

NOTE: The hinge helps to keep the tree from

twisting andfalling inthe wrong direction.

Use a wedge ifthere is any chance that the tree

will not fall inthe desired direction.

C. BUCKING

Bucking is the term used for cutting a fallen tree

to the desired log size.

1. IMPORTANT POINTS

a. Cut only one log atatim e.

b. Cut shattered wood very carefully. Sharp

pieces of wood could be flung toward the

operator.

c. Use a sawhorse to cut small logs. Never

allow another person to holdthe log while cut-

ting and never holdthelogwith your legor foot.

d. Give special attention to logs under strain to

prevent the saw from pinching. Make the first

cut on the pressureside to relieve the stress on

the log.Figure 32.

e. Do not cut in an area where logs, limbs and

roots are tangled such as in a blown down

area. Drag the logs intoa clear area before cut-

ting by pulling out exposedand cleared logs_

first.

f. Make the f_rst bucking cut 1/3 of the way

through the log and finish with a2/3 cut on

the opposite side. As the log is being cut, it

wilt tend to bend. The saw can become

pinched or hung inthe log if you make the first

cut deeper than 1/3 of the diameter of the log.

2. TYPES OF CUTTING USED Figure33.

-- Overcutting - begin on the top side of the

log with the spur against the log: exert light

pressure downward.

.- Undercutting - begin on the under sideof the

log with the top of the sawagainst the log;exert

light pressure upward. During undercutting,

the saw will tend to push back at you. Be pre-

pared for this reaction and hold the saw firmly

to maintain control.

• AWARNING " _ _I

Never turn the saw upside down to undercut. The

saw cannot be controlled in this position.

_WARNING

If saw becomes pinched or hung in alog, don't try to

force it out. You can lose control of the saw resulting

in injury and/or damage to the saw. Stop the saw,

drive a wedge of plastic orwood into the cut until the

saw can be removed easily. Figure 34, Restart the

saw and carefully reenter the cut. To avoid kickback

and chain damage, do not use a metal wedge. Do

not attempt to restart your saw when it is pinched or

hung in a log.

3. BUCKING--WlTHOUTA SUPPORT

a. Overcutwith a 1/3 diametercut.

MAINTAINSECUREFOOTING

,,,,111i i , i r ,,,

O. DEBRANCHING AND PRUNING

•Work slowly, keeping both hands on the saw

with a firm grip. Maintain secure footing and bal-

ance.

•Watch out for springpoles. Use extreme caution

when cutting small size limbs. Slender material can

catch the saw chain and be whipped toward you or

pull you off balance.

• Be alert for springback. Watch out for branches

that are bent or under pressure as you are cutting

to avoid being struckby the branchor the saw when

the tension in the wood fibers is released.

• Keep a clear work area. Frequently clear bran-

ches out of the way to avoid trippingoverthem.

AWARNING

Never climb into a tree to debranch or prune. Do not

stand on laUders, platforms, a log or in any position

which can cause you to lose your balance or control of

the saw.

i_ DEBRANCHING ........

a. Always debranch a tree after it is cut down.

Only then can debranching be done safely

and properly.

b. Leave the larger lower limbs to supportthe

tree as you work.

c. Start at the base of the felled tree and work

towards the top, cutting branches and

limbs. Remove small limbs with one cut. Fig-

ure 37.

d. Keep the tree between you and the chain.

Cut from the side of the tree opposite the

branch you are cutting.

e. Remove larger, supporting branch_s with

the 1/3, 2/3 cutting techniques described in

the bucking section.

f. Always use an overcut to cut small and

freely hanging limbs. Undercutting can cause

limbs to fall and pinch the saw,

oPRUNING

a. Limit pruning to limbs shoulder height or

below. Do not cut if branches are higherthan

your shoulder. Get a professional to do the

job.

b. Refer to Figure38 for the pruning tech-

nique.

1.) Undercut 1/3 of the way through the limb

near the trunk ofthe tree.

2.) Finish with an overcut farther out from the

trunk.

3.) Keep out of the way of the falling limb.

.4.) Cut the stump flush near the trunk of the

tree.

_ILWARNING

Be alert for and guard against kickback. Do not allow

the moving chain to aontact any other branches or

objects at the nose of the guide bar when debranching

Orpruning. Allowing such contact can result inserious

injury.

1. CHAIN MAINTENANCE

• Sharpen the chain when:

--wood chips are small and powdery. Wood

chips made by the saw chain should be

about the size of the teeth of the chain.

--saw has to be forced through the cut.

--saw cuts to one side.

ICAUTION:I Always wear gloves when handling

the chain. The chain is sharp enough to cut you

even though it is too dull to cut wood.

a. SHARPENING INSTRUCTIONS

Ite_ns required:

Gloves Medium Flat File

7/32" dis. file Depth Gauge Tool

i:)

2.)

3.)

.

Stop engine and disconnect spark plug,

Adjust the chain for proper tension. See

"Chain Tension':

Work at the midpoint of the bar, moving the

chain forward by hand as each cutter is

filed.

) Sharpen cutters.

a.) Position flat side of file holder (with

7132" round file)on cu_er topplateand depth

gauge. Figure 39.

b. ) Hold the fite holder level with the 30° guide

mark parallel to the center of the chain.

Figure 40.

c.) File from inside toward outside of cutter,

straight across, on forward strokeronly.Use

2 or3 strokes per cutting edge. Figure 40,

d. ) Keep all cutters the same length. Figure 41.

chance of kickback which can result in sedous Injury.

• b. CHAIN REPLACEMENT

1.) Use onlythe Low-Kick Chain specified for

your saw in "Specifications, for replace-

ment chain.

2.) Replace the chain when cutters or links

break.

3.)

4.)

See your Sears Service Center to replace

and sharpen individual cutters for match-

ing your chain.

Always have a worn sprocket replaced by

your Sears Service Center when installing

a new chain to avoid excessive wear to the

chain.

2. GUIDE BAR MAINTENANCE

• Conditions which can require guide bar

maintenance:

--saw cuts to one side

--saw has to be forced through a cut

inadequate oil supply to bar and chain.

'e Check the condition of the guide bar each

time the chain is sharpened. A worn guide

bar will damage the chain and make cut-

ting more difficult.

• Replace the guide bar when:

--the inside groove of the guide bar rails is

worn.

--the guide bar is bent or Cracked.

• Use only the Reduced-Kickback Guide Bar

specified for your saw in "Specifications"

for replacemenL

a. Remove the guide bar to service.

b. Clean oil holes at least once for each

five hours of operation.

c. Remove sawdust from the guide bac

groove periodically with a putty knife oc

a wire. Figure45.

d.

"e.

Remove burrs by filing the side edges

of the guide bar grooves square with a

flat file. Figure46.

Restore square edges to an uneven rail

top by filing with a flat file. Figure39.
