SAFETY RULES

WARNING: Always disconnect
spark plug wire and place wire where it can­not contact spark plug to prevent accidental starting when setting up, transporting, ad­justing or making repairs except carburetor adjustments. Because a chain saw is a high-speed wood­cutting tool, special safety precautions must be observed to reduce the risk of accidents. Careless or improper use of this tool can cause serious injury.
PLAN AHEAD
S Read this manual carefully until you com-
pletely understand and can follow all safe­ty rules, precautions, and operating in­structions before attempting to use the unit.
S Restrict the use of your saw to adult users
who understand and can follow safety rules, precautions, and operating instruc­tions found in this manual.
Hearing
Protection
Snug Fitting
Clothing
Safety Shoes
S Wear protective gear. Always use steel-
toed safety footwear with non-slip soles; snug-fitting clothing; heavy-duty, non-slip gloves; eye protection such as non-fog­ging, vented goggles or face screen; an approved safety hard hat; and sound barri­ers (ear plugs or mufflers) to protect your hearing. Regular users should have hear­ing checked regularly as chain saw noise can damage hearing. Secure hair above shoulder length.
S Keep all parts of your body away from the
chain when the engine is running.
S Keep children, bystanders, and animals a
minimum of 10 Meters away from the work area. Do not allow other people or animals to be near the chain saw when starting or operating the chain saw.
S 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. 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.
Safety Hat
Eye Protection
Heavy Duty Gloves
Safety Chaps
S Carefully plan your sawing operation in ad-
vance. Do not start cutting until you have a clear work area, secure footing, and, if you are felling trees, a planned retreat path.
OPERATE YOUR SAW SAFELY
S Do not operate a chain saw with one hand.
Serious injury to the operator, helpers, by­standers or any combination of these per­sons may result from one-handed opera­tion. A chain saw is intended for two-handed use.
S Operate the chain saw only in a well-venti-
lated outdoor area.
S Do not operate saw from a ladder or in a
tree, unless you are specifically trained to do so.
S 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.
S Do not put pressure on the saw at the end of
the cut. Applying pressure can cause you to lose control when the cut is completed.
S Stop the engine before setting the saw
down.
S Do not operate a chain saw that is dam-
aged, improperly adjusted, or not com­pletely and securely assembled. Always replace bar, chain, hand guard, or chain brake immediately if it becomes damaged, broken or is otherwise removed.
S With the engine stopped, hand carry the
chain saw with the muffler away from your body, and the guide bar and chain to the rear, preferably covered with a scabbard.
MAINTAIN YOUR SAW IN GOOD WORKING ORDER
S Have all chain saw service performed by a
qualified service dealer with the exception of the items listed in the maintenance 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 fly ­wheel to burst.
S Make certain the saw chain stops moving
when the throttle trigger is released. For correction, refer to CARBURETOR AD­JUSTMENTS.
S Never modify your saw in any way. Use
only attachments supplied or specifically recommended by the manufacturer.
S Keep the handles dry, clean, and free of oil
or fuel mixture.
S Keep fuel and oil caps, screws, and fas-
teners securely tightened.
S Use only JonseredR accessories and re-
placement parts as recommended.
HANDLE FUEL WITH CAUTION
S Do not smoke while handling fuel or while
operating the saw.
S Eliminate all sources of sparks or flame in
the areas where fuel is mixed or poured. There should be no smoking, open flames, or work that could cause sparks. Allow en­gine to cool before refueling.
3
S Mix and pour fuel in an outdoor area on bare
ground; store fuel in a cool, dry, well venti­lated place; and use an approved, marked container for all fuel purposes. Wipe up all fuel spills before starting saw.
S Move at least 10 feet (3 meters) from fuel-
ing site before starting engine.
S Turn the engine off and let saw cool in a
non-combustible area, not on dry leaves, straw, paper, etc. Slowly remove fuel cap and refuel unit.
S Store the unit and fuel in an area where fuel
vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.
KICKBACK
WARNING: Avoid kickback which
can result in serious injury. Kickback is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar con­tacts any object such as a log or branch, or when the wood closes in and pinches the saw chain in the cut. Contacting a foreign ob­ject in the wood can also result in loss of chain saw control. S Rotational Kickback can occur when the
moving chain contacts an object at the up­per tip of the guide bar. This contact 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.
S Pinch-Kickback can occur when the the
wood closes in and pinches the moving saw chain in the cut along the top of the guide bar and the saw chain is suddenly stopped. 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. The saw is driven straight back toward the operator.
S Pull-In can occur when the moving chain
contacts a foreign object in the wood in the cut along the bottom of the guide bar and the saw chain is suddenly stopped. This sudden stopping pulls the saw forward and away from the operator and could easily cause the operator to lose control of the saw.
Avoid Pinch -- Kickback:
S Be extremely aware of situations or obstruc-
tions that can cause material to pinch the top of or otherwise stop the chain.
S Do not cut more than one log at a time. S Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull -- In:
S Always begin cutting with the engine at full
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.
Kickback Path
Avoid obstructions
Clear the working area
REDUCETHECHANCEOF KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.
S Never let the moving chain contact any ob-
ject at the tip of the guide bar.
S Keep the working area free from obstruc -
tions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting through a particular log or branch.
S Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase the chance of kickback occurring. Follow manufacturer’s chain sharpening and main­tenance instructions. Check tension at regu­lar intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after ten­sioning the chain.
S Begi nand continue cutting at full speed. If
the chain is moving at a slower speed, there is greater chance of kickback occur­ring.
S Cut one log at a time. S Use extreme caution when re-entering a
previous cut.
S Do not attempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
S Use the Reduced-- Kickback Guide Bar
and Low-- Kickback Chain specified for your saw.
MAINTAIN CONTROL
Stand to the left of the saw
Never reverse hand positions

Symmetrical Guide Bar
Elbow locked
Thumb on underside of handlebar
S Keep a good, firm grip on the saw with both
hands when the engine is running and don’t let go. A firm grip will help you reduce kickback and 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 your are right handed or left handed. Keep your left arm straight with the elbow locked.
S Position your left hand on the front handle-
bar so it is in a straight line with your right hand on the rear handle when making bucking cuts. Never reverse right and left hand positions for any type of cutting.
S Stand with your weight evenly balanced on
both feet.
S Stand slightly to the left side of the saw to
keep your body from being in a direct line with the cutting chain.
S Do not overreach. You could be drawn or
thrown off balance and lose control of the saw.
S Do not cut above shoulder height. It is diffi-
cult to maintain control of saw above shoulder height.
KICKBACK SAFETY FEATURES
WARNING: The following features
are included 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 only on safety devices. You must follow all safety precautions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury. S Reduced--Kickback Guide Bar, designed
with a small radius tip which reduces the size of the kickback danger zone on the bar tip. A Reduced--Kickback Guide Bar has been demonstrated to significantly re­duce the number and seriousness of kick­backs.
Reduced Kickback Symmetrical Guide Bar
Small Radius Tip
S Low--Kickback Chain, designed with a
contoured depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cutter.
Low-Kickback Chain
S Handguard, designed to reduce the
chance of your left hand contacting the chain if your hand slips off the front handle­bar.
S Position of front and rear handlebars, de-
signed with distance 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.
WARNING: DO NOT RELY UPON
ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced-- kickback guide bars and low-- kickback saw chains reduce the chance and magnitude of kickback and are recommended. Your saw has a low kick­back chain and bar as original equipment. Repairs on a chain brake should be made by an authorized servicing dealer. T ake your unit to the place of purchase if purchased from a servicing dealer, or to the nearest au­thorized master service dealer. S Tip contact in some cases may cause a
lightning fast reverse REACTION, kicking the guide bar up and back toward the oper­ator.
S Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly back toward the operator.
S Either of these reactions may cause you to
lose control of the saw which could result in serious injury. Do not rely exclusively upon the safety devices built into your saw.
CHAIN BRAKE
S Chain brake, designed to stop the chain in
the event of kickback.
WARNING: Your chain saw is
equipped with a chain brake that is designed to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them. DO NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK.

Users who operate power tools on a continual and regular basis must monitor closely their physical condition and the condition of this tool.
Protective gloves (not provided) should be worn during assembly.
ATTACHING THE BUMPER SPIKE
The bumper spike may be used as a pivot when making a cut.
1. Loosen and remove the chain brake nuts and the chain brake from the saw.
2. Attach the bumper spike with the two screws as illustrated.
ATTACHING THE BAR & CHAIN (If
not already attached)
WARNING: Recheck each assem-
bly step if the saw is received assembled. Al­ways wear gloves when handling the chain. The chain is sharp and can cut you even when it is not moving!
1. Loosen and remove the chain brake nuts and the chain brake from the saw.
2. Remove the plastic shipping spacer (if present).

10. Pull guide bar forward until chain is snug in guide bar groove. Ensure all drive links are in the bar groove.
11. Now, install chain brake making sure the adjusting pin is positioned in the lower hole in the guide bar. Remember this pin moves the bar forward and backward as the screw is turned.
12. Install chain brake nuts and finger tighten only. Once the chain is tensioned, you will need to tighten chain brake nuts.
CHAIN TENSION (Including units with chain already installed)
NOTE
: When adjusting chain tension, make
sure the chain brake nuts are finger tight only. Attempting to tension the chain when the chain brake nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the chain adjust­ment tool (bar tool) to move the chain around the bar. If the chain does not rotate, it is too tight. If too loose, the chain will sag below the bar.
Chain Brake Nuts
Adjusting the tension:
Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw.
Chain Adjustment
Tool (Bar Tool)
Always check chain tension each time you use and refuel your saw. You can adjust the chain tension by loosening the chain brake nuts and turning the adjusting screw 1/4 of a turn while lifting up on the bar. S If chain is too tight, turn adjusting screw 1/4
turn counterclockwise.
S If chain is too loose, turn adjusting screw
1/4 turn clockwise.

OPERATING YOUR UNIT

BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
information in the safety rules before you be­gin. If you do not understand the safety rules, do not attempt to fuel your unit. Contact an authorized service dealer.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri­cation. 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 bar. Only use Bar and Chain Oil for bar and chain lubrication.
Oil Cap
Fuel mix ca p
FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling. This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 0,125 liter of oil with 5 liters of unleaded gasoline. DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules relating to fuel before fueling your unit.

IMPORTANT
Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the en­gine and let it run until the fuel lines and carbu­retor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner prod­ucts in the fuel tank or permanent damage may occur.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling the front hand guard back toward the front han­dle as far as possible. The chain brake must be disengaged before cutting with the saw.
WARNING: The chain must not
move when the engine runs at idle speed. If the chain moves at idle speed refer to CAR­BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns. To stop the engine, move the ON/STOP switch to the STOP position. To start the engine, hold the saw firmly on the ground as illustrated below. Make sure the chain is free to turn without contacting any object.
Use only 15--- 1 8 of rope per pull. Hold saw firmly while pulling starter rope.
IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly. For cold weather starting, start the unit at full choke; allow the engine to warm up before squeezing the throttle trigger.
NOTE: Do not cut material with the choke/fast
idle lever at the FULL CHOKE position.
STARTING A COLD ENGINE (or a warm engine after running out of fuel)

OFF HALF
DIFFICULT STARTING (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by pushing the choke/fast idle lever in completely (to the OFF CHOKE position) and then following the warm engine starting procedure listed above. Ensure the ON/ STOP switch is in the ON position. Starting could require pulling the starter rope handle many times depending on how badly the unit is flooded. If engine fails to start, re­fer to the TROUBLESHOOTING TABLE.
CHAIN BRAKE
WARNING: If the brake band is worn
too thin it may break when the chain brake is triggered. With a broken brake band, the chain brake will not stop the chain. The chain brake should be replaced by an authorized service dealer if any part is worn to less than 0,02(0,5 mm) thick. Repairs on a chain brake should be made by an authorized ser­vice dealer. Takeyour unit to the place of pur­chase if purchased from a servicing dealer, or to the nearest authorized master service dealer. S This saw is equipped with a chain brake.
The brake is designed to stop the chain if kickback occurs.

CUTTING METHODS

IMPORTANT POINTS
S Check chain tension before first use and af-
ter 1 minute of operation. See CHAIN TEN­SION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair parts as necessary.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain and increase the possibility of kickback.
S Practice cutting a few small logs using the
following techniques to get the “feel” of us­ing your saw before you begin a major sawing operation. S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keep the engine at full speed the entire
time you are cutting.
S Allow the chain to cut for you. Exert only
light downward pressure.
S Release the throttle trigger as soon as
the cut is completed, allowing the en­gine to idle. If you run the saw at full throttle without a cutting load, unneces­sary wear can occur.
S To avoid losing control when cut is com-
plete, do not put pressure on saw at end of cut.
S Stop the engine before setting the saw down.
TREE FELLING TECHNIQUES
WARNING: Do not cut near buildings
or electrical wires if you do not know the di­rection of tree fall, at night since you will not be able to see well, or during bad weather such as rain, snow, or strong winds. as fall is unpredictable.
should be placed on the ground with the en­gine running. Place the saw on firm ground. Grip the rear handle with your right hand and the front han­dle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain brake by turning your left wrist against the hand guard without releasing your grip around the front handle. The chain should stop immediately.
Inertia activating function control
WARNING: When performing the fol-
lowing procedure, the engine must be turned off. Grip the rear handle with your right hand and the front handle with your left hand. Hold the chain saw approximately 14” (35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.
Carefully plan your sawing operation in ad­vance. You need a clear area all around the tree so you can have secure footing. Check for broken or dead branches which can fall on you causing serious injury. Natural conditions that can cause a tree to fall in a particular direction include:
S The wind direction and speed. S The lean of the tree. The lean of a tree
might not be apparent due to uneven or sloping terrain. Use a plumb or level to de­termine the direction of tree lean.
S Weight and branches on one side. S Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator. Make sure there is enough room for the tree to fall. Maintain a distance of from the nearest 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.

FELLING LARGE TREES
(15cmindiameterorlarger)
The notch method is used to fell 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 side of tree, the tree will tend to fall into the notch.

NOTCH CUT AND FELLING THE TREE
S Make notch cut by cutting the top of the
notch first. Cut through of the tree. Next complete the notch by cut­ting the bottom of the notch. See illustra­tion. Once the notch is cut remove the notch of wood from the tree.
Final cut here. 5 cm above
First cut
Notch
Second cut
S After removing the wood from the notch,
make the felling cut on the opposite side of the notch. This is done by making a cut about two inches higher than the center of the notch. This will leave enough uncut wood between the felling cut and the notch to form a hinge. This hinge will help prevent the tree from falling in the wrong direction.
Hinge holds tree on stump and helps control fall
center of notch.

Important points
S Cut only one log at a time. S Cut shattered wood very carefully; sharp
pieces of wood could be flung toward oper­ator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while cutting and never hold the log with your leg or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a clear area before cutting by pulling out ex­posed and cleared logs first.
TYPES OF CUTTING USED FOR BUCKING
WARNING: If saw becomes pinched
or hung in a log, 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 or wood into the cut until the saw can be removed easily. Restart the saw and carefully reenter the cut. Do not attempt to restart your saw when it is pinched or hung in a log.
Turn sa w OFF and use a plastic or wooden wedge to force cut open.
Overcutting begins on the top side of the log with the saw against the log. When overcut­ting use light downward pressure.
Overcutting
Undercutting
Closing of notch
NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to control the direction of fall. To avoid kickback or chain damage, use wood or plastic wedges, but never steel or iron wedges.
S Be alert to signs that the tree is ready to fall:
cracking sounds, widening of the felling cut, or movement in the upper branches.
S As tree starts to fall, stop saw, put it down,
and get away quickly on your planned re­treat path.
S DO NOT cut down a partially fallen tree with
your saw. Be extremely cautious with par­tially fallen trees that may be poorly sup­ported. When a tree doesn’t fall completely, set the saw aside and pull down the tree with a cable winch, block and tackle, or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen tree to the desired log length.
WARNING: Do not stand on the log
being cut. Any portion can roll causing loss of footing and control. Do not stand downhill of the log being cut.
Undercutting involves cutting on the under­side of the log with top of saw against the log. When undercutting use light upward pres­sure. Hold saw firmly and maintain control. The saw will tend to push back toward you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be con­trolled in this position.
First cut on pressure side of log

S Roll the log over and finish with a second
overcut.
S 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.
BUCKING USING A LOG OR SUP­PORT STAND
S Remember your first cut is always on the
pressure side of the log.
S Your first cut should extend
diameter of the log.
S Finish with your second cut.

IMPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slen­der material may catch the saw chain and be whipped toward you or pull you off balance.
S Be alert for springback. Watch out for
branches that are bent or under pressure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping over them.
LIMBING
S Always limb a tree after it is cut down. Only
then can limbing be done safely and prop­erly.
S Leave the larger limbs underneath the
felled tree to support the tree as you work.
S Start at base of the felled tree and work to-
ward the top, cutting branches and limbs. Remove small limbs with one cut.
S Keep the tree between you and the chain
as much as possible.
S Remove larger, supporting branches with
the cutting techniques described in BUCK­ING WITHOUT A SUPPORT.
S Always use an overcut to cut small and
freely hanging limbs. Undercutting could cause limbs to fall and pinch saw.
PRUNING
WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job. S Make your fist cut
the bottom of the limb.
S Next make a 2nd cut all the way through
the limb. Then cut a third overcut leaving
a 1 to 2 inch collar from the trunk of the tree.

AIR FILTER
CAUTION: Do not clean filter in gaso-
line or other flammable solvent to avoid creating a fire hazard or producing harmful evaporative emissions.
Cleaning the air filter:
A dirty air filter decreases engine perform­ance and increases fuel consumption and harmful emissions. Always clean after every 5 hours of operation.
1. Clean the cover and the area around it to keep dirt and sawdust from falling into the carburetor chamber when the cover is removed.
2. Remove the parts as illustrated below.
3. Wash the filter in soap and water. Rinse in clean cool water. Air dry completely before reinstalling.
4. Add a few drops of oil to the filter; squeeze filter to distribute oil.
5. Reinstall parts.

sary to service your bar. A worn bar will dam­age your chain and make cutting difficult. After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Move ON/STOP switch to the STOP posi-
tion.
S Loosen and remove chain brake nuts and
chain brake. Remove bar and chain from saw.
S Clean the oil holes and bar groove after each
5 hours of operation.

S Burring of guide bar rails is a normal
process of rail wear. Remove these burrs with a flat file.
S When rail top is uneven, use a flat file to re-
store square edges and sides.

Replace guide bar when the groove is worn, the guide bar is bent or cracked, or when excess heating or burring of the rails occurs. If replacement is necessary, use only the guide bar specified for your saw in the repair parts list or on the decal located on the chain saw.
SPARK PLUG
The spark plug should be replaced each year to ensure the engine starts easier and runs better. Ignition timing is fixed and non­adjustable.
1. Loosen 3 screws on cylinder cover.
2. Remove the cylinder cover.
3. Pull off the spark plug boot.
4. Remove spark plug from cylinder and discard.
5. Replace with Champion RCJ--7Y spark plug and tighten securely with a 19 mm socket wrench. Spark plug gap should be 0,5 mm.
6. Reinstall the spark plug boot.
7. Reinstall the cylinder cover and 3 screws. Tighten securely.

CHAIN SHARPENING
Chain sharpening is a complicated task that requires special tools. We recommend that you refer chain sharpening to a professional chain sharpener.
CARBURETOR ADJUSTMENTS
WARNING: The chain will be moving
during most of this procedure. Wear your pro­tective equipment and observe all safety pre­cautions. The chain must not move at idle speed. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: S Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Saw will not idle. See IDLE SPEED--T ad-
justing procedure.
Idle Speed-- T
Allow engine to idle. If the chain moves, idle is too fast. If the engine stalls, idle is too slow. Adjust speed until engine runs without chain movement (idle too fast) or stalling (idle too slow). The idle speed screw is located in the area above the primer bulb and is labeled T. S Turn idle speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.
STORAGE
WARNING: Stop engine and allow to
cool, and secure the unit before storing or transporting in a vehicle. 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 with all guards in place. Position so that any sharp object cannot accidentally cause injury to passersby. Store the unit out of reach of children. S Before storing, drain all fuel from the unit.
Start engine and allow to run until it stops.
S Clean the unit before storing. Pay particu-
lar attention to the air intake area, keeping it free of debris. Use a mild detergent and sponge to clean the plastic surfaces.
S Do not store the unit or fuel in a closed area
where fuel vapors can reach sparks or an open flame from hot water heaters, electric motors or switches, furnaces, etc.
S Store in a dry area out of the reach of chil-
dren.
CAUTION: It is important to prevent
gum deposits from forming in essential fuel system parts such as the carburetor, fuel fil­ter, fuel hose, or fuel tank during storage. Al­cohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to fuel mixture separation and formation of acids during storage. Acidic gas can damage the engine.
