specifically trainedto do soo

•Position all parts of your body to the left of cut and

away from the chain when the engine is running,

.Cut wood only. Do not use yoursawto pryorshoveaway

limbs,roots,or other objects,

• Make sure the chain will not make contact with any

object while starting the engine. Nevertry to start the

saw when the guide bar is in a cutor keff,

.Use extreme caution when cuttingsmall size brush and

saplings. Slender material can catch the chain and be

whippedtoward you or pull you off balance..

-Be alert for springbeck when cutting a limb that is under

tension so you wilt not be struck by the limb or saw when

the tension inthe wood fibersis released.

• Do not put pressure on the saw at the end of a cuL

Applying pressurecan cause you to lose control whenthe

cut is completed.

Stop the engine before setting the saw down.

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.

. Make certain the chain stops moving when the throttle

trigger is released. For correction, refer to "Carburetor

Adjustments:'

.Stop the saw if the chain strikes a foreign object.

Inspectunitand repairor replace partsas necessary,

GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury.

KICKBACK WARNING:

KICKBACK CAN OCCUR WHEN THE

MOVING CHAIN CONTACTS AN OBJECT AT

THE UPPER PORTION OF THE TIP OF THE

GUIDE BAR OR WHEN THE WOOD CLOSES

IN AND PINCHES THE CHAIN IN THE CUT.

CONTACT ATTHE UPPER PORTION OFTHE

TIP OF THE GUIDE BAR 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 TOWARDTHE OPERATOR. IF

THE CHAIN IS PINCHED ALONG THE TOP

OF THE GUIDE BAR, THE GUIDE BAR CAN

BE DRIVEN RAPIDLY BACK TOWARD THE

OPERATOR. EITHER OFTHESE REACTIONS

CAN CAUSE LOSS OF SAW CONTROL

WHICH CAN RESULT IN SERIOUS INJURY.

DO NOT RELY ONLY ON THE SAFETY

DEVICES PROVIDED WITH YOUR SAW. AS A

CHAIN SAW USER, YOU MUST TAKE SPE-

CIAL SAFETY PRECAUTIONS TO HELP

REDUCETHE CHANCE OF KICKBACK

° Recognize that kickback can happen. With abasic

understandingof kickback, you can reduce the element of

surprise which contributes to accidents,,

•Never let the moving chain contact any object at the tip

of the guide bar. Figure 2.

.Keep the working area free from obstructions such as

othertrees,branches, rocks, fences,stumps,etc. Figure3.

Eliminateoravoid any obstruction that yourchain couldhit

whileyouare cuttingthrougha particularlog or branch_

-Keep your chain sharp and properly tensioned. A loose

or'dutlchaincan increase the chance of kickback to occur.

Followmanufacturer's chain sharpeningand maintenance

instructionsCheck tension at regular intervalswith the

enginestopped, never withthe enginerunning_Make sure

the bar clampnutsare securely tightenedafter tensioning

the chain_

•Begin andcontinue cutting at full throttle. If the chainis

moving ata slower speed, there is greaterchance for kick-

back to occur,

•Cut one log at a time.

•Use extreme caution when re-entering a previous cut,

=Do not attempt plunge cuts.

•Watch for shifting logs orother forcesthat couldclosea

cut and pinchor fat! intochain,.

-Use the Reduced-Kickback Guide Bar and Low-

Kickback Chain specifiedfor your saw.

KICKBACK SAFETY FEATURES

l_ WARNING:

THE FOLLOWING FEATURES ARE INCLUD-

ED ON YOUR SAW TO HELP REDUCE THE

HAZARD OF KICKBACK; HOWEVER, SUCH

FEATURES WILL NOT TOTALLY ELIMINATE

THIS DANGEROUS REACTION. AS A CHAIN

SAW USER, DO NOT RELY ONLYON SAFETY

DEVICES.YOU MUST FOLLOW ALL SAFETY

PRECAUTIONS, INSTRUCTIONS, AND MAIN-

TENANCE IN THIS MANUALTO HELP AVOID

KICKBACK AND OTHER FORCES WHICH

CAN RESULT IN SERIOUS INJURY.

Reduced-Kickback Guide Bar, designed with a small

radiustip which reduces the size of the kickback danger

zone on the guide bar tip. Figure 5. A Reduced-Kickback

Guide Bar is one which has been demonstrated to signif-

icantly reduce the number and seriousness of kickbacks

when tested in accordance with ANSI BI75,1-199l.

•Low-Kickback Chain, designed with a contoured depth

gauge and guard link which deflect kickback force and

allow woodto gradually ride intothe cutter:Figure 5. Low-

KickbackChain is chain which has met kickback perfor-

mance requirements of ANSI B175,,1-1991 when tested

on a representativesample of chain saws below 3.8 cubic

inchdisplacement specified in ANSI B175_1-1991.

MAINTAIN CONTROL

.Keep a good, firm grip on the saw with both hands

when the engine is running and don't let go. Figure4.

A firm gdp can neutralizekickback and help you maintain

control of the saw. Keepthe fingers of your left hand encir-

cling 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.

°Position your left hand on the front handlebar so it is

in a straight line with your right hand on the rear han-

dle when making bucking cuts, Figure4. Never'reverse

right and left hand positions forany typeof cutting.

oStand with your weight evenly balanced on both feet.

, Stand slightly to the left side of the saw to keep your

body from being in a direct line with the cutting chain.

Figure 4.

•Do not overreach. Youcould be drawn or thrown off bal-

ance and losecontrol of the saw.

o Do not cut above shoulder height. It isdifficult to main-

talncontrolof saw above shoulder height.

UNDERSTANDING REACTIVE FORCES

Pinch-Kickback and PulHn occur when the chain is sud-

denly stopped by being pinched, caught, or by contact-

ing a foreign object in the wood_Thisstoppingofthechain

results inareversalof the chainforce usedto cut woodand

causes the saw to move in the opposite direction of the chain

rotation,.Either reaction can result in loss of control and pos-

sible serious injury.

•Pinch-Kickback

-occurs when chain on top of guide bar is suddenly

stopped.

-rapidly drives saw straight back toward operator.

•Puff-In

- occurs when the chain on the bottom of the guide bar is

suddenly stopped,.

-pulls the saw rapidly forward

• Handguard, designed to reduce the chance of your left

hand contacting the chain if your hand slips off the front

handlebar_

•Position of front and rear handlebars, designed with

distance between handlesand "in-line" with each other:

The spread and "imline" positionof the hands providedby

thisdesign work togetherto give balance and resistance

in controllingthe pivotof the saw back toward the opera-

tot if kickbackoccurs

GUIDE BAR AND CHAIN OIL

For maximum guide bar and chain life, we recommend you

use Craftsman chain saw bar oil, If Craftsman bar oil is not

available, you may use a good grade SAE30 oil until you

are able to obtain Craftsman brand.The oil output is auto-

matically metered during operation_ Your saw will use

approximately one tank of bar oil for every tank of fuel mix°

Always fill the bar oil tank when you fill the fuel tank.

GASOLINE

The two-cycle engine on this product requires a fuel mix-

ture of regular unleaded gasoline and a high quality 40:1

2-cycle engine oil (AIR-COOLED) for lubrication of the

bearings and other moving parts.The correct fuetloit mix-

ture is 40:1 (see Fuel Mixture Chart). Too little oil or the

incorrect oil type will cause poor performance and may

cause the engine to overheat and seize.

Gasoline and oil must be premixed in a clean approved fuel

container, Always use fresh regular unleaded gasoline°

This engine is certified to operate on unleaded gasoline.,

IMPORTANT: Experience indicates that alcohol blended

fuels called gasohol (or using ethanol or methanol) car!

attract moisture, which leads to oittgas separation and for-

mation of acids during storage. Acidic gas can damage the

fuel system of an engine while in storage.To avoid engine

problems, the fuel system should be emptied before stor-

age for 30 days or longer° Drain the gas tank, then runthe

fuel out of the carburetor and fuel lines by starting the

engine and letting it run until it stops.. Use fresh fuel next

season. See STORAGE instructionsfor additional informa.-

tion. Never use engine or carburetor cleaner products in

the fuel tank or permanent damage may occur_

FUEL STABILIZER

Fuel stabilizer is an acceptable alternative in minimizing

the formation of fuel gum deposits during storage, Add sta-

bilizer' to gasoline in fuel tank or storage container,. Always

follow the fuel mix ratio found on the stabilizer container,

Run engine at least 5 minutes after adding stabiIizer to

allow the stabilizer' to reach the carburetor.You do not have

to drain the fuel tank for storage if you are using fuel stabi-

lizer.

CRAFTSMAN 40:1 2-cycte engine oil (AIR-COOLED) is

specially blended with fuel stabilizers° If you do not use

this Sears oil, you can add a fuel stabilizer to your fuel tank.,

40:1 2-CYCLE AIR-COOLED ENGINE OIL

CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is

strongly recommended.This oil is specially blended with

fuel stabilizers for increased fuet stability (extends fuel life

up to 5 times longer) and reduced smoke,.

If CRAFTSMAN 40:1 2*cycle engine oil (AIR-COOLED) is

not available, use a good quality 2-cycle engine oil (AIR..

COOLED) that has a recommended fuel mix ratio of 40:1.

IMPORTANT! Do not use:

-AUTOMOTIVE OIL.

o BOAT OILS (NMMA, BIA, etc.)

These oils do not have proper additives for 2-cycle (AIR-

COOLED) engines and can cause engine damage

GASOLINE AND OIL MIXTURE

Mix gasoline and oii as follows:

.Consuft chart for correctquantities.

° Do not mix gasolineand oil directly inthe unit'sfuel tank°

FOR ONE GALLON:

•Pour 3.2 ounces of high quality, 40:1 2-cycle engine oil

(AIR-COOLED) into an empty, approved one gallon

gasoline container.

• Add one gallon of regular unleaded gasoline to the gallon

container, then securely replace the cap.

-Shake the container momentarily.

•The mixture is now ready for use. Fuel stabilizer can be

added at this time if desired;follow mixing instructions on

the label.,

OPERATION

GENERAL OPERATION TIPS

•Cut wood only. Do not cut metal; plastics; masonry; non-

wood building materials; etc.

°Stop the saw if the chain strikes a foreign object. Inspect

the saw and repair' or replace parts as necessary.

• Keep the chain out of dirt and sand.,Even a small amount

of dirt wilt quickly dull a chain and thus increase the pos-

sibility of kickback_

To get the "feel" of using your saw before you begin a major

sawing operation, practice cutting a few small logs using

the following technique:

• Accelerate engine to full throttle by squeezing the throttle

trigger' before entering cut.

*Never cut with engine at partial speeds.

•Begin cutting with the saw chassis against the logo

* Keep engine at full throttle during cutting procedure_

° Allow the chain to cut for you; exert only light downward

pressure If you force the cut, damage to the bar, chain,

or engine can result.

o Release the throttle trigger as soon as the cut is com-

pleted, allowing the engine to idle. If you run the unit at

full throttle without cutting, unnecessary wear' can occur

to the chain, bar', and engine.

° To avoid losing control when completing the cut, do not

put pressure on the saw during the end of the cuL

oStop engine before setting unit down after cperationo

OPERATION SAFETY

WARNING:

IF SAW BECOMES PINCHED OR HUNG IN A

LOG, DO NOT 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 OR WOOD INTO THE

CUT UNTIL THE SAW CAN BE REMOVED

EASILY. RESTARTTHE SAW AND CAREFUL-

LY REENTER THE CUT. TO AVOID KICK-

BACK 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.

KICKBACK CAN OCCUR WHEN THE MOV-

ING CHAIN CONTACTS AN OBJECT AT THE

UPPER PORTION OFTHE TIP OFTHE GUIDE

BAR OR WHENTHE WOOD CLOSES IN AND

PINCHES THE SAW CHAIN IN THE CUT.

CONTACT ATTHE UPPER PORTION OFTHE

TIP OF THE GUIDE BAR CAN CAUSE THE

CHAIN TO DIG tNTOTHE OBJECT AND STOP

THE CHAIN FOR AN INSTANT.THE RESULT

IS A LIGHTNING FAST,REVERSE REACTION

WHICH KICKS THE GUIDE BAR UP AND

BACK TOWARD THE OPERATOR. IF THE

SAW CHAIN IS PINCHED ALONG THE TOP

OF THE GUIDE BAR, THE GUIDE BAR CAN

BE DRIVEN RAPIDLY BACK TOWARD THE

OPERATOR. EITHER OFTHESE REACTIONS

CAN CAUSE LOSS OF SAW CONTROL

WHICH CAN RESULT IN SERIOUS INJURY.

AVOID REACTIVE PINCH FORCES

Pinch-Kickback and Pull-In occur when the chain is sud-

denly stopped by being pinched, caught, or by contacting

a foreign object in the wood, 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. Pinch-Kickback drives the saw

straight back toward the operator. Pull-in pulls the saw

away from the operator: Either reaction can result in loss of

control and possibty serious injury°

TO AVOID PINCH-KICKBACK:

•Be extremely aware of situations or obstructions that can

cause material to pinch the top of cr otherwise stop the

chain_

= Do not cut more than one log at a time

= Do not twist the saw as the bar is withdrawn from an

under.cut when bucking°

TO AVOID PULL-IN:

,, Always begin cutting withthe engine at full throttle and

the saw housing against wood.

= Use wedges made of plastic or wood, (never' of metal) to

hold the cut open,

OPERATION

TREE FELLING

WARNING:

IF THE TRUNK OR LIMBS ARE ROTTING,

THEY CAN FALL UNEXPECTEDLY AND

CAUSE SERIOUS INJURY.

AS YOU MAKE YOUR FELLING CUT, IF THE

SAW APPEARS TO BE BINDING, THE TREE

IS STARTING TO FALL IN THE WRONG

DIRECTION. IMMEDIATELY STOP THE SAW

AND USE A FELLING WEDGE AND MAUL

(HAMMER) TO FORCE THE FELLING CUT

OPEN. THE WEDGE WILL HOLD THE

FELLING CUT OPEN ALLOWING YOU TO

REMOVETHE SAW. KEEP EVERYONE AWAY

FROM THE TREE IN ALL DIRECTIONS.

DETERMINETHE NATURAL FALL DIRECTION

•Wind - Atree evenly balanced will fall in the same direc-

tion the wind is blowing.

• Lean - Use a carpenter's level or plumb bob to deter-

mine if tree has anatural leanoA leaning tree will tend to

fall in direction of leano

•Shape - A tree will tend to fall towards side that is more

heavily branched.

• Other Factors - Contacting or nearby trees, buildings, or

wires can influence the direction the tree will fall.

CUTTING PROCEDURE (Fig. 22)

After determining the Natural Fall Direction, the tree should

be cut as follows:

IMPORTANT: BEFORE FELLING A TREE, MAKE SURE

YOU HAVE AT LEAST 3 FELLING WEDGES AND A

MAUL (HAMMER) AVAILABLE FOR USE IF NEEDED°

• Use some means to visually mark the Natural Fail

Direction,

• Mark your notch cut on the Natural Fall Direction side of

the tree approximately 18-24 inches above the ground,r

•Cut top of the notch first at a45 degree angle° Saw

through 1/3 of the width of the tree,

• Cut bottom of the notch at a 45 degree angle until you

meet the top notch cuL Remove notch of wood.

•On the side of the tree opposite the notch cut, make the

felling cut.The foiling cut should be 2 inches above the

center point of the notch cuL Before the felling cut is

complete, use wedges to open the cut when necessary

to control the direction of the fall.. Use wood or plastic

wedges, but never steel or iron, to avoid kickback and

chain damager

• Cracking sounds, widening of the felling cut, movement

inthe upper branches are all signs that the tree is ready

to fall,

• As tree begins to fall, turn off saw, and move quickly

away from direction of fall.

Figure 22

If your chain saw binds in the felling cut, you have three

options:

•If the wrong direction of fall is acceptable, carefully

remove the felling wedge°Cut deeper in the notchside of

the tree until tree starts to fall.

. If the wrong direction of fall is not acceptable, attempt to

use one or more felling wedges to force the tree in the

original direction of fall Do so by driving the wedges

deeper into the felling cut°

•Keep everyone away from the tree in all directions and

then seek professional help!

FELLING TiPS

• Clear the workarea ofdebris where you can have secure

footing,.

.Make sure there is enough room for the tree to fall,

Maintain a distance of 2 1/2 tree lengths from the near-

est person or other objects. Engine noise can drown out

a warning call

•Remove dirt, stones, loose bark, nails, staples, and wire

from the tree where cuts are to be made.

°Plan to stand on the up-hill side when cutting on a sloper

• Plan a clear retreat path to the rear and diagonalto the

line of fall.

* Large buttress roots should be removed prior to notch

cut.

.Use a wedge if there is any chance that the tree will not

fall in the desired direction.

.We recommendyou cut branches below shoulder height

before felling tree,,(See Limbing and Pruning).

Be alert to signs that the tree is ready to fall:

•Cracking sounds.

• Widening of the felling cut.

•Movement in the upper branches_

-Look for decay and rot. If the trunk is rotted,it can snap

and fall toward the operator..

•Check for broken or dead branches which can fal! on

youwhile cutting

• Be extremely cautious with partially fallen trees that may

be poorly supported. When a tree doesn't fatl completely,

set the saw aside and pull down the tree with a cable

winch, block and tackle, or tractorr,TOavoid injury, do not

cut down a partially fallen tree with your saw.

OPERATION

BUCKING

Bucking is cutting a fallen tree to the desired log size,,

TYPES OF CUTTING (Fig. 23)

.Overcutting - begin on the top side of the log with the

bottom of the saw chassis against the log; exert light

pressure downward.

,, Undercutting - begin on the underside of the log withthe

top of the saw chassis against the log; exert light pres-

sure upward. Dudng undercutting, the saw will tend to

push back at you,,Be prepared for this reaction and hotd

the saw firmly to maintain control,

BUCKING TIPS

*Cut only one log at a time.

•Cut shattered wood very carefully. Sharp pieces of wood

could be flung toward the operator.

,Use a sawhorse to cut small Iogs. Never allow another

person to hold the log while cutting and never hold the

log with your leg or foot.

,Do not cut in an area where logs, limbs, and roots are

tangled such as in a blown down area. Drag the logs into

a clear area before cutting by pulling out exposed and

cleared logs first.

,Give special attention to logs under strain to prevent the

saw from pinching. Make the first cut on the pressure

side to relieve the stress on the log.

GAS CHAIN SAW STORAGE INSTRUCTIONS

If your chain is to be stored for aperiod of time, clean it

thoroughly prior to storage. Remove any dirt, sawdust,

Ieaves, oil, grease, etcoStore in a clean dry area°

• Clean the entire unit.

•CIean air filter. Refer to "Customer Responsibilities?

•Inspect the bar clamp area and clean any dirt, sawdust,

grass, or debris that has collected. Inspect the guide bar

and chain; replace a guide bar that is bent, warped,

cracked, broken, or damaged in any other way. Replace

a damaged or worn chain.

= Lightly oil external metal surfaces to prevent rust from

forming.

•Apply a coating of oil to the entire surface of the guide

bar and chain; wrap it in heavy paper or cloth.

° Be sure all handles and guards are in place and are

securely fastened. Replace any damaged parts.

FUEL SYSTEM

Never use engine or carburetor cleaner products in the fuel

tank or permanent damage may occur to fuel system com-

ponents. Follow these instructions:

• Drain the fuel from the unit into an approved fuel con-

tainer

• Drain the fuel lines and carburetor by starting the engine

and letting it run until it stops.

° Allow the engine to cool before storage.

IMPORTANT: it is important to prevent gum deposits from

forming in essentialfuel system parts such as the carbure-

tor,fuel filter,fuel hose or tank during storage.. Also, expe-

rience indicatesthat alcohol blended fuels, those that use

ethanol or methanol (called gasohol or oxygenated fuel),

canattract moistureand form acidic gas which will damage

your engine°To avoid engine problems, the fuel system

should be emptiedbefore storage of 30 days or longer.

Fuel stabilizer is an acceptable alternative in minimizing

the formation of fuel gum deposits during storage. Add sta-

bilizer to the gasoline in the fuel tank or fuel storage con-

tainer.Always follow the mix instructionsfound on stabilizer

containers. Run engine at least 5 minutes after adding sta-

bilizer to allow the stabilizer to reach the carburetor°

CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is

specially blended with fuel stabilizer.r If you do not use this

Sears oil, you can add a fuel stabilizer to your fuel tank.

INTERNAL ENGINE

•Remove spark plug and pour I teaspoon of 40:1 2_cycle

engine oil (AIR-COOLED) through the spark plug open-

ing_Slowly pull the starter rope 8 to 10 times to distribute

oil to inner engine surfaces.

•Replace spark plug with a new one of the recommended

type and heat range. Refer to "Product Specifications°"

•Ctean air filter. Refer to "Customer Responsibilities_"

•Re-install all covers and hardware removed for access;

tighten all screws and fasteners.

Replace any damaged, broken, or worn parts.

• t.ightly oif external meta! surface to prevent rust from

forming,.

•Use fresh fuel having the proper gasoline to oil ratio at

the beginning of the next season,

OTHER

•Do not store gasoline from one season to another,

• Replace your gasoline can if your can starts to rust. Rust

and/or dirt in your fuel system will cause problems.

,Store your unit in a wel! ventilated area and covered, if

possible, to prevent dust and dirt accumulation. Do not

cover with plastic, Plastic cannot breathe and will induce
