OPERATE YOUR SAW SAFELY

• Do not operate a chain saw with one hand. Serious

injury to the operator, helpers, bystanders or any combi-

nation of these persons may result from one-handed

operation. A chain saw is intended for two-handed use.

• Operate the chain saw only in outdoor areas.

• Do not operate saw from a ladder or in a tree, unless specifically trained to do so.

• Position all parts of your body to the left of cut and away from the saw chain when the engine is running.

• Cut wood only. Do not use your saw to pry or shove away limbs, roots, or other objects.

• 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 or kerr.

• Use extreme caution when cutting small size brush

and saplings. Slender material can catch the saw chain

and be whipped toward you or pull you off balance.

• 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 inthe wood fibers is released.

• Do not put pressure on the saw at the end of a cut. Applying pressure can cause you to lose control when

the cut is compJeted.

• Stop the engine before setting the saw down.

• Keep fuel and oil caps, screws, and fasteners

securely tightened.

i..¢1 iii i1=

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

• Have all chain saw service performed by your Sears

Service Center with the exception of the items listed in

the customer responsibilities 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.

• Make certain the saw 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. Inspect the unit and repair or replace parts as necessary.

• Disconnect the spark plug before performing any maintenance except for carburetor adjustments.

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

ufacturer.

TRANSPORTING AND STORAGE

• Stop the unit before transporting.

• Allow the engine to cool, cover the bar and chain, and secure the unit before storing or transporting in a vehicle.

• Empty the fuel tank before storing or transporting the unit. Use up any fuel left in the carburetor by starting the

engine and letting the engine run until it stops.

• Store unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric

motors or switches, furnaces, etc.

• Store unit so the chain cannot accidentally cause injury.

• Store the unit out of the reach of children.

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 AT THE UPPER PORTION OF THE 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 TOWARD THE 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 OF THESE REACTIONS CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERI-

OUS INJURY. DO NOT RELY ONLY ON THE SAFETY DEVICES PROVIDED WITH

YOUR SAW. AS A CHAIN SAW USER, YOU MUST TAKE SPECIAL SAFETY

PRECAUTIONS TO HELP KEEP YOUR

CUTTING JOBS FREE FROM ACCIDENT OR INJURY.

• Keep your chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback

to occur. Follow manufacturer's chain sharpening and maintenance instructions.Check tension at regular inter-

vals with the engine stopped, never with the engine run- ning. Make sure the bar clamp nuts are securely tight-

ened after tensioning the chain.

• Begin and continue cutting at full throttle, If the chain

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

• Cut one log at a time.

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

KICKBACK SAFETY FEATURES

_ WARNING:

Reduced-Kickback Guide Bar, designed with a small

radius tip 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 signifi-

cantly reduce the number and seriousness of kickbacks when tested in accordance with ANSI B175.1-1991.

• Low-Kickback Chain, designed with a contoured depth gauge and guard link which deflects kickback force and allow wood to gradually ride into the cutter. Figure 5. Low-Kickback Chain is chain which has met kickback

UNDERSTANDING REACTIVE FORCES

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

suddenly stopped by being pinched, caught, or by con- tacting a foreign object in the wood. This sudden stop- ping of the chain results in a reversal of the chain force used to cut wood and causes the saw to move inthe oppo-

site directionof the chain rotation,Either reactioncan result in lossof controland possible serious injury.

• Pinch-Kickback

- occurs when chain on top of guide bar is suddenly

stopped.

- rapidly drives saw straight back toward operator.

° Pull-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 front and rear handlebars, designed with dis- tance between handles and "in-line" with each other. The

spread and "in-line" position of the hands provided by this design work together to give balance and resistance in

controlling the pivot of the saw back toward the operator if kickback occurs.

CUTTING TECHNIQUES (Fig. 20 & 21)

• Overcutting - begin on the top side of the log with the bottom of the saw against the log; exert lightpressure

downward.

• Undercutting - begin on the under side of the tog with

the top of the saw against the log;exert light pressure

upward. During undercutting, the saw will tend to push back at you. Be prepared for this reaction and hold the

saw firmly to maintain control.

Front Saw Frame"

Figure 21

CUTTING SPEED

• Accelerate engine to full throttle before entering cut by squeezing the throttle trigger.

• Never cut with engine at partial throttle speed.

OPERATION USE/TIPS

• Cut wood only. Do not cut metal; plastics; masonry; men-wood building materials; etc.

• Stop the saw if the chain strikes a foreign object. Inspect the saw and repair or replace parts as neces-

sary.

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

amount of dirt will quickly dull a chain and thus

increase the possibilityof 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 before entering cut by squeezing the throttle trigger.

• Begin cutting with the saw frame against the tog.

- Keep.engine at full throttle during cutting procedure. ° Allow the chain to cut for you; exert only light down-

ward pressure. If you force the cut, damage to the bar, chain, or engine can result.

• 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 cut. Stop engine before setting unit down after operation.

GENERAL 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. RESTART THE SAW AND CAREFULLY RE-ENTER THE CUT. TO

AVOID KICKBACK AND CHAIN DAMAGE,

DO NOT USE A METAL WEDGE. DO NOT

ATTEMPT TO RE-START YOUR SAW WHEN IT IS PINCHED OR HUNG IN A LOG.

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 SAW CHAIN

IN THE CUT. CONTACT AT THE UPPER PORTION OF THE TIP OF THE GUIDE BAR

CAN CAUSE THE CHAIN TO DIG INTO THE 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 OPERA- TOR. EITHER OF THESE 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 contact-

ing 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 possibly serious injury.

TO AVOID PINCH-KICKBACK:

• Be extreme_ aware of situations or obstructions that can cause material to pinch the top of or 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 with the engine at full throttle and the front saw frame against the wood.

• Use wedges made of plastic or wood, (never of metal) to hold the cut open.

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 REMOVE THE

SAW. KEEP EVERYONE AWAY FROM THE

TREE IN ALL DIRECTIONS.

DETERMINE THE NATURAL FALL DIRECTION

• Wind - A tree evenly balanced will fatl in the same direc- tion the wind is blowing.

• Lean - Use a carpenter's level or ptumb bobto determine if tree has a natural lean. A leaning tree will tend to fal! in direction of lean.

• 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.

I CUTrlNG PROCEDURE (Fig. 22)

After determining the Natural Fa_lDirection, 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 Fall Direction.

• Mark your notch cut on the Natural Fall Direction side of the tree approximately 18-24 inches above the ground.

• Cut top of the notch first at a 45 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 cut. Remove notch of wood.

• On the side ofthe tree opposite the notch cut, make the telling cut. The felling cut should be 2 inches above the center point of the notch cut. 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, buI never steel or iron, to avoid kickback and chain damage.

• Cracking sounds, widening of the felling cut, movement in the upper branches are all signs that the tree is ready

to fall

• As tree begins to fall, move ON/STOP switch to "Stop" position, set it down, and move quickly away from

direction of fall.

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

• If the wrong direction of fall is acceptable, carefully remove the fellingwedge. Cut deeper in the notch side 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 fal!. Do so by driving the wedges

deeper into the felling cut.

• Keep everyone away from the tree in aFIdirections and

then seek professional help!

NOTE: For trees less than 6 inches in diameter, make a

single feilingcut on the side away from the direction of fall. Cut through until tree begins to fall. Then turn off saw, set it

down, and move quickly away from direction of fall.

OPERATION USE/TIPS

• Clear the work area of debris where you can have secure footing.

• Make sure there is enough room for the tree to fall. Maintain a distance of 2 !/2 tree lengths from the nearest person or other objects. Engine noise can drown out a

warning call.

• Remove dire, stones, loose bark, nails, staples, and wire from the tree where cuts are to be made.

• Plan to stand on the up-HI side when cutting on a slope.

° Plan a clear retreat path to the rear and diagonal to the

line of fall.

• If unsure about which way a tree will fal!, use the notch cutting method.

• 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 recommend you cut branches below shoulder height

before felling tree. (See Limbing and Pruning).

Be alert to signs that the tree is readyto fall:

. • Cracking sounds.

• Widening of the felling cut.

• Movement in the upper branches.

........................ OPERATION

BUCKING

Bucking iscutting a fallen tree to the desired log size.

TYPES OF CU'I-rlNG (Fig. 23)

• Overcutting - begin on the top side of the log with the bottom of the saw against the log; exert light pressure

downward.

• Undercutting - begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During undercutting, the saw will tend to push back at you. Be prepared for this reaction and hold the

saw firmly to maintain control.

Undercut

Figure 23

BUCKING ON THE GROUND (Fig. 24)

• Overcut with a 1/3 diameter cut.

• Roll log over and finish with an overcut using a wedge

to hold open the cut.

BUCKING USING A SUPPORT (Fig. 25 & 26)

Another log or a stand, such as a sawhorse, may be used as supports when bucking.

BEFORE STARTING THE ENGINE:

WARNING:

BE SURE TO READ THE FUEL SAFETY INFORMATION IN THE SAFETY RULES SECTION ON PAGE 2 OF THIS MANUAL

BEFORE YOU BEGIN.

IF YOU DO NOT UNDERSTAND THE FUEL SAFETY SECTION DO NOT

ATTEMPT TO FUEL YOUR UNIT; SEEK

HELP FROM SOMEONE THAT DOES UNDERSTAND THE FUEL SAFETY SECTION OR CALL THE CUSTOMER ASSISTANCE HOTLINE AT 1-800-235-5878.

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 SAE 30

oil until you are able to obtain Craftsman brand. The oil output is automatically metered during operation. Your

saw will use 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 AIR-COOLED engine oil for lubrication of the bearings and other moving parts. The correct fueVoi!

m_xture is 40:1 _see Fue! Mixture Chart). Too little oil- or the incorrect oil type will cause poor performance and may cause the engine to overheat and seize.

FUEL STABILIZER

Fuel stabilizer is an acceptable alternative in minimizing

the formation of fuet gum deposits during storage. Add stabilizer 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 sta-

bilizer to allow the stabilizer to reach the carburetor. You do not have to drain the fuel tank for storage if you are

using fuel stabilizer. CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil is

specially blended with fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer (such as

Craftsman No. 33500) to your fuel tank.

40:1 2-CYCLE AIR-COOLED ENGINE OIL:

CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil is strongly recommended. This oil is specially blended with

fuel stabilizers for increased fuel stability (extends fuel life up to 5 times longer) and reduced smoke.

If CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oi! is

not available, use a good quality 40:1 2-cycle AiR-

COOLED engine oi_ that has a recommended fuel mix

ratio of 40:1.

IMPORTANT! Do not use:

* AUTOMOTIVE OIL . 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

i iiiii ii i

Gasoline and oil must be premixed in a clean approved

fuel container. Always use fresh regular unleaded gaso-

line.

This engine is certified to operate on unleaded gasoline. IMPORTANT: Experience indicates that alcohol blended

fuels called gasohol (or using ethanol or methanol) can attract moisture, which leads to oil/gas separation and formation of acids during storage. Acidic gas can dam- age the fue! system of an engine while in storage. To avoid engine problems, the fuel system should be emp-

tied before storage for 30 days or longer. Drain the gas tank, then run the 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"

instructions for additional information. Never use engine

or carburetor cleaner products inthe fuel tank or perma- nent damage may occur.

Mix gasoline and oil as follows:

• Consult chart for correct quantities.

• Do not mix gasoline and oil directty in the unit's fuel tank.

FOR ONE GALLON: ° Pour 3.2 ounces of high quality, 40:1 2-cycted AIR-

COOLED engine oil into an empty, approved one gallon gasoline container.

• Add one galion of regular unleaded gasoline to the gallon container, then securely replace the cap.

• Shake the container.

• The mixture is now ready for use. Fuel stabilizer can be added at this time if desired; follow mixing instructions

on the label.

FUEL MIXTURE CHART

40:1 Fuel:Oil Mix Ratio

SERVICE AND ADJUSTMENTS

IIIIIll II I I

CARBURETOR ADJUSTMENTS

Carburetor adjustment is critical and if done improperly can permanently damage the engine as well as the car- buretor. Please read all instructions and consultthe Troubleshooting section of this manual before beginning

this process.

If the engine does not start, it may be flooded. If in

doubt, read the section on flooded engine in the starting section of this manual prior to beginning any adjust-

ments.

If you are unsure about adjusting the carburetor or expe-

rience any problem while attempting this process, please

call the 1-800 number listed on the front cover of this manual for further assistance.

The carburetor has been adjusted at the factory for sea

level conditions. Adjustments may become necessary if the unit is used at significantly higher altitudes or if you notice any of the following conditions: ° Chain moves when.the engine runs at idle speed. See

"Idle Speed Adjustment."

• Saw will not idle. See "Idle Speed Adjustment" and "Low Speed Mixture Adjustment."

• Engine dies or hesitates when it should accelerate. See "Acceleration Adjustment."

• Loss of cutting power which is not corrected by air filter cleaning. See "High Speed Mixture Adjustment."

NOTE: Do not attempt to adjust the screw beyond the

stops as damage can occur.

WARNING:

THE CHAIN WILL BE MOVING DURING MOST OF THIS PROCEDURE. WEAR YOUR PROTECTIVE EQUIPMENT AND

OBSERVE ALL SAFETY PRECAUTIONS.

CARBURETOR PRESETS (Fig. 58)

If your engine will not start due to suspected improper carburetor adjustment, the following presets may be required. If used, it is recommended that all steps within

the adjustment procedure be completed in order to assure a propedy set carburetor. If presets are not need- ed, proceed to section "tdle Speed Adjustment."

Very small adjustments can affect engine performance.

It is important to turn the screw a very small amount per adjustment and test performance before making further adjustments. Each adjustment should be no more than

the width of the slot in the adjusting screw.

CAUTION:

DO NOT TURN SCREWS TOO TIGHT;

THIS WILL RESULT IN DAMAGE TO NEEDLE TIPS AND NEEDLE SEATS.

IF CHAIN MOVES WHEN ENGINE IDLES,

TURN IDLE SPEED SCREW COUNTER-

CLOCKWISE UNTIL CHAIN STOPS.

° Turn both low and high speed mixture screws clock-

wise until a slight resistance is felt.

• Turn both mixture screws counterclockwise one full turn.

• Turn idle speed screw clockwise 1/2 turn.

Using these presets, the unit should start and run.

IN "LOW SPEED MIXTURE ADJUST-

MENT," RECHECK IDLE SPEED AFTER EACH ADJUSTMENT. THE CHAIN MUST

NOT MOVE AT IDLE SPEED.

ADJUSTING PROCEDURE

IDLE SPEED ADJUSTMENT

• Allow the warn engine to idle.

• Adjust idle speed screw until engine continues to run

without stalling.

- Turn screw clockwise to increase engine speed if

the engine stalls or dies.

- Turn screw counterclockwise to slow engine down and/or to keep the chain from turning.

• No further adjustments are necessary if the chain does not move at idle speed and if performance is satisfactory.

LOW SPEED MIXTURE ADJUSTMENT

• Allow engineto idle.

• Turn the Low Speed Mixture Screw slowly clockwise until the RPM starts to drop. Note the position.

• Turn the Low Speed Mixture Screw slowly counterclock- wise until the RPM speeds up and starts to drop again,

Note the position,

• Set the Low Speed Mixture Screw at the midpoint between the two positions,

HIGH SPEED MIXTURE ADJUSTMENT IMPORTANT:DO NOT OPERATE ENGINE AT FULL THROTTLE FOR PROLONGED PERIODS WHILE

MAKING HIGH SPEED ADJUSTMENTS AS DAMAGE

TO THE ENGtNE CAN OCCUR.

• Make a test cut.

• Based on performance of the saw while cutting, adjust the High Speed Mixture Screw in 1/16 turn increments

as follows:

- Clockwise ff saw smokes or loses power in the cut.

Do not adjust for best power by sound or speed, but

judge by how well the saw performs in the cut.

- Counterclockwise if the saw has speed while out of the

cut, but dies in the cut or lacks poser while cutting,

• Repeat the test cut.

• Continue with 1/16 turn adjustments until the saw performance is acceptable while cutting.

° After completing adjustments, check for acceleration.

WARNING:

A CARBURETOR SETTING THAT IS TOO LEAN (CLOCKWISE ADJUSTMENT ON

HIGH SPEED SCREW FOR MAXIMUM

SPEED) WILL CAUSE ENGINE DAMAGE TO ANY 2-CYCLE ENGINE FROM OVER- HEATING AND LACK OF LUBRICATION.

NEVER SET THE HIGH SPEED SCREW SO FAR CLOCKWISE THAT YOU HAVE ENGINE SPEED LACKING POWER TO CUT.

AN EFFECTIVE APPROACH FOLLOWS:

- TURN HIGH SPEED SCREW COUNTER- CLOCKWISE UNTIL ENGINE LOSES

POWER WHILE CUTTING.

-TURN HIGH SPEED SCREW CLOCK- WISE USING 1/16 TURN INCREMENTS

ONLY UNTIL THE ENGINE HAS POWER

WHILE CUTTING.

IF THE ENGINE DOES NOT OPERATE ACCORDING TO THESE INSTRUCTIONS AFTER REPEATING THE ADJUSTING

STEPS, DO NOT USE THE UNIT. FOR

FURTHER ASSISTANCE, PLEASE CALL

OUR CUSTOMER ASSISTANCE HOTLINE AT 1-800-235-5878.

ACCELERATION CHECK

• If the engine dies or hesitates instead of accelerating, turn the Low Speed Mixture Screw 1/16 of a turn at a

time counterclockwise until you have smooth acceleration.

• Check the idle speed for stability and no chain move- ment, Adjust as necessary.

° Recheck for smooth acceleration and stable idle.

Repeat process as necessary for acceptable

performance.

GAS CHAIN SAW STORAGE

INSTRUCTIONS

If your chain saw is to be stored for a period of time,

Clean it thoroughly prior to storage. Remove any dirt, leaves, oil, grease, etc. Store in a clean dry area.

• Clean the entire unit.

• Clean air filter. Refer to "Customer Responsibilities".

• Open the semi-automatic line head assembiy and clean any dirt, grass or debris that has collected.

• Inspect the bar clamp area and clean any dirt, saw- dust, 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.

CAUTION: WEAR PROTECTIVE GLOVES

WHEN HANDLING LINE LIMITER. THE BLADE IS SHARP AND CAN CUT YOU.

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

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

• Be sure all handles and guards are in place and are securely fastened. Replace any damaged parts.

fuel tank or permanent damage may occur to fuel sys- tem components.

Follow these instructions:

• Drain the fuel from the unit into an approved fuet con- tainer.

• Drain the fuel lines and carburetor by starting the

engine and letting it run until it stops.

• Allow the engine to coot before storage. IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts such as the

carburetor, fuel filter, fuel hose or tank during storage.

Also, experience indicates that alcohol blended fuels, those that use ethanol or methanol (called gasohol or oxygenated fuel), can attract moisture and form acidic gas which will damage your engine. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer.

Fuel stabilizer is an acceptable alternative in minimizing

the formation of fuel gum deposits during storage. Add stabilizer to the gasoline in the fuel tank or fuel storage container. AIways follow the mix instructions found on stabilizer containers. Run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the car-

buretor.

CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil is specially blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer (such as CRAFTSMAN No. 33500) to your fuel tank.

INTERNAL ENGINE

• Remove spark plug and pour 1 teaspoon of 40:! 2-

cycle AIR-COOLED engine oil through the spark plug opening. 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".

. Clean air filter. Refer to "Customer Responsibilities".

• Re-install all covers and hardware removed for access; tighten all screws and fasteners.

• Check entire unit for loose screws, nuts, and bolts. Replace any damaged, broken, or worn parts.

• Lightfy oi! external metal 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 wil! cause prob- lems.

, Store your unit in a wetl ventilated area and covered, if

possible, to prevent dust and dirt accumulation. Do not cover with plastic. Plastic cannot breathe and will

induce condensation and eventual rust or corrosion.

IMPORTANT: NEVER COVER UNIT WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
