SAFETY RULES
WARNING: Always disconnect
spark plug wire when making repairs ex­cept for carburetor adjustments. Be­cause a chain saw is a high-speed wood-cutting tool, special precautions must be observed to reduce the risk of accidents. Careless or improper use of this tool can cause serious injury.
PLAN AHEAD
Restrict the use of your saw to adult
users who understand and can follow safety rules, precautions, and operat­ing instructions found in this manual.
Snug Fitting
Clothing
Safety Shoes
Safety Chaps
Heavy Duty Gloves
Eye Protection
Hearing
Protection
Safety Hat
Wear protective gear. Always use
steel-toed safety footwear with non­slip soles; snug-fitting clothing; safety chaps; 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. Do
not wear loose clothing or jewelry; they can get caught in moving parts.
Keep all parts of your body away from
the chain when the engine is running.
Keep children, bystanders, and ani-
mals a minimum of 30 feet (10 me­ters) away from the work area when starting and using the saw.
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. If you have any condition that might be aggravated by strenuous work, check with doctor before operating.
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
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.
Operate the chain saw only in a well­ventilated outdoor area.
Do not operate saw from a ladder or in a tree.
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.
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.
Stop engine before setting saw down.
Hand carry saw only when engine is
stopped. Carry with muffler away from body; guide bar and chain proj­ecting behind you; guide bar covered with a scabbard.
Do not operate a chain saw that is damaged, 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.
MAINTAIN YOUR SAW IN GOOD WORKING ORDER
WARNING: Disconnect the
spark plug before performing mainte­nance except carburetor adjustments.
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.
Make certain the saw chain stops moving when the throttle trigger is released. For correction, refer to
CARBURETOR ADJUSTMENT.
Keep the handles dry, clean, and free from oil or fuel mixture.
Keep caps and fasteners securely tightened.
Nonconforming replacement compo­nents or the removal of safety devices may cause damage to the unit and
5
possible injury to the operator or by­standers. Use only Craftsman acces­sories and replacement parts as rec­ommended. Never modify your saw.
Maintain chain saw with care.
Keep unit sharp and clean for better
and safer performance.
Follow instructions for lubricating and changing accessories.
Check for damaged parts. Before fur­ther use of the chain saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by a Sears Service Center unless otherwise indicated elsewhere in the operator’s manual.
When not in use, chain saws should be stored in a dry, high or locked-up place out of the reach of children.
When storing saw, use a scabbard or carrying case.
HANDLE FUEL WITH CAUTION
Do not smoke while handling fuel or while operating the saw.
Eliminate all sources of sparks or flame in the areas where fuel is mixed or poured.
Always have fire extinguishing tools available if you should need them.
Mix and pour fuel in an outdoor area and use an approved, marked con­tainer for all fuel purposes. Wipe up all fuel spills before starting saw.
Move at least 10 feet (3 meters) from fueling site before starting engine.
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.
Empty the fuel tank before storing or transporting the unit. Use up fuel left in the carburetor by starting the engine and letting it run until it stops.
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.
GUARD AGAINST KICKBACK
Follow all safety rules to help avoid kickback and other forces which can result in serious injury.
Kickback Path
Clear The Working Area
Avoid Obstructions
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.
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.
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.
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.
6
REDUCE THE CHANCE OF KICKBACK
Recognize that kickback can hap­pen. With a basic understanding of 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.
Keep the working area free from ob­structions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting.
When cutting a branch, do not let the guide bar contact branch or other ob­jects around it.
Keep saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback. Fol­low manufacturer’s chain sharpening and maintenance instructions. Check tension at regular intervals, but never with the engine running. Make sure the bar nuts are securely tightened.
Begin and continue cutting at full speed. If the chain is moving at a slower speed, there is greater chance of kickback occurring.
Use extreme caution when re-enter­ing a previous cut.
Do not attempt cuts starting with the tip of the bar (plunge cuts).
Watch for shifting logs or other forces that could close a cut and pinch or fall into chain.
Use the Reduced--Kickback Guide Bar and Low--Kickback Chain speci­fied for your saw.
Avoid Pinch--Kickback:
Be extremely 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 undercut when bucking.
Avoid Pull--In:
Always begin cutting with the engine at full speed and the saw housing against wood.
Use wedges made of plastic or wood. Never use metal to hold the cut open.
MAINTAIN CONTROL
Never reverse hand positions
Stand
to
the
leftofthe
saw
Thumb on underside of handlebar
Elbow locked
A good, firm grip on the saw with both hands will help you maintain control. Don’t let go. Grip the rear handle with your right hand whether you are right or left handed. Wrap the fingers of your left hand over and around the front handlebar, and your left thumb under the front handlebar. 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 handle when making bucking cuts. Never reverse right and left hand positions for any type of cutting.
Stand with your weight evenly bal­anced on both feet.
Do not overreach. You could be drawn or thrown off balance and lose control of the saw.
Do not cut above shoulder height. It is difficult to maintain control of saw above shoulder height.
KICKBACK SAFETY FEATURES
WARNING: The following fea-
tures are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this danger. Do not rely only on safety devices. Follow all safety rules to help avoid kickback and other forces which can result in serious injury.
Front Hand Guard, 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 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.
Reduced--Kickback Guide Bar, designed with a small radius tip which
7
reduces the size of the kickback dan­ger zone on the bar tip. This type of bar has been demonstrated to signifi­cantly reduce the number and serious­ness of kickbacks when tested in accordance with ANSI B175.1.
Large Radius Tip Guide Bar
Small Radius Tip Guide Bar
Low--Kickback Chain, has met kick­back performance requirements when tested on a representative sample of chain saws below 3.8 cubic inch displacement specified in ANSI B175.1--2012.
Low-KickbackChain
Contoured Depth Gauge
Elongated Guard Link deflects kickback force And allows wood to gradually ride into Cutter
CHAIN BRAKE
Chain Brake, designed to stop the chain in the event of kickback.
WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS­SUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. Kickback is a lightning fast
action which throws the bar and rotat­ing chain back and up toward the op­erator. Kickback can be caused by al­lowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. 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 Sears Service Center. Take your unit to the place of purchase if
purchased from a servicing dealer, or to your nearest Sears Service Center.
Tip contact in some cases may cause a lightning fast reverse REACTION, kicking guide bar up and back toward operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator.
Either of these reactions may cause you to lose control of the saw which could result in serious injury. Do not rely exclusively upon devices built into your saw.
This unit is equipped with an anti­vibration system and is intended for occasional use only.
SAFETY NOTICE: Exposure to vibra­tions through prolonged use of gasoline powered hand tools could cause blood vessel or nerve damage in the fingers, hands, and joints of people prone to circulation disorders or abnormal swell­ings. Prolonged use in cold weather has been linked to blood vessel damage in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of this tool and seek medical attention. An anti-vi­bration system does not guarantee the avoidance of these problems. Users who operate power tools on a continual and regular basis must monitor closely their physical condition and the condition of this tool. CHAIN BRAKE: To comply with Federal OSHA Regulations for Com­mercial Logging, a chain brake is required and shall not be removed or otherwise disabled.
SPARK ARRESTING SCREEN: Your saw is equipped with a temperature limiting muffler and spark arresting screen which meets the requirements of California Codes 4442 and 4443. All U.S. forest land and the states of California, Idaho, Maine, Minnesota, New Jersey, Oregon, and Washington require by law that many internal com­bustion engines to be equipped with a spark arresting screen. If you operate a chain saw in a state or locale where such regulations exist, you are legally responsible for maintaining the operat­ing condition of these parts. Failure to do so is a violation of the law. Refer to the Customer Responsibilities chart in the MAINTENANCE section.

The chain brake activates manually if the front hand guard is pushed forward. The chain brake is disengaged by pulling the front hand guard back toward the front handle as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch during the first 15 minutes of operation. You should check your chain tension each time before you start the chain saw. See CHAIN TENSION under the
MAINTENANCE section.
WARNING: If the saw is oper-
ated with a loose chain, the chain could jump off the guide bar and result in serious injury to the operator and/or damage the chain making it unusable.
BEFORE STARTING ENGINE
WARNING: Muffler is very hot
during and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so.
WARNING: Be sure to read the
fuel handling information in the safety rules section of this manual before you begin. If you do not understand the fuel handling information do not at­tempt to fuel your unit. Seek help from someone that does understand the in­formation or call the customer assis­tance help line at 1-800-235-5878.
GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication. The chain oiler provides continuous lubrication to the chain and guide bar. Be sure to fill the bar oil tank when you fill the fuel tank (Capacity = 6.8 fl. oz.). 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. 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
approximately one tank of bar oil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank.
FUELING ENGINE
WARNING: Remove fuel cap
slowly when refueling. IMPORTANT: This equipment is de­signed to operate on unleaded gasoline with a minimum 87 octane (R+M/2 method), with ethanol blended up to 10% maximum by volume (E-10). Before operation, gasoline must be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 50:1. Craftsman brand synthetic oil is recommended. Mix gasoline and oil at a ratio of 50:1. A 50:1 ratio is obtained by mixing
2.6 fluid ounces of oil with 1 gallon of
unleaded gasoline. DO NOT USE auto­motive oil or marine oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on con­tainer. Once oil is added to gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. CAUTION: Never use straight gasoline in your unit. This will cause permanent engine damage and void the limited warranty. Do not use alternate fuels such as ethanol blends above 10% by volume (E-15, E-85) or any methanol blended fuel. Use of these fuels can cause major engine performance and durability problems.

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 ADJUST-
MENT within this manual. Avoid contact
with the muffler. A hot muffler can cause serious burns.
STOPPING YOUR ENGINE
Release the throttle trigger.
Move ON/STOP switch to the STOP
position.

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 TROU-
BLESHOOTING TABLE or call
1-800-235-5878.
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 must be replaced if any part is worn to less than 0.020”(0.5 mm) thick. Repairs on a chain brake should be made by your Sears Service Center. Take your unit to the place of purchase or to the near­est Sears Service Center.
This saw is equipped with a chain
brake. The brake is designed to stop the chain if kickback occurs.
The inertia--activated chain brake is
activated if the front hand guard is pushed forward, either manually (by hand) or automatically (by sudden movement).
If the brake is already activated, it is
disengaged by pulling the front hand guard back toward the front handle as far as possible.
When cutting with the saw, the chain
brake must be disengaged.
Engaged
Disengaged
Braking function control CAUTION: The chain brake must be
checked several times daily. The engine must be running when performing this procedure. This is the only instance when the saw 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.
OPERATING TIPS
Check chain tension before first use and after 1 minute of operation, and each time before you start the chain saw. See CHAIN TENSION in the
MAINTENANCE section.
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. If the chain jumps off the guide bar, inspect the chain for damaged drive links before reinstalling. Burrs on drive links, which prevent them from entering the groove of the guide bar, can be removed with a flat file.
Keep the chain out of dirt and sand. Even a small amount of dirt will dull a chain, increase the possibility of kick­back, and require chain sharpening or replacement.
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.
Squeeze the throttle trigger and al-
low the engine to reach full speed before cutting.
Begin cutting with the saw frame
against the log.
Keep the engine at full speed the
entire time you are cutting.
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.
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 to the chain, bar, and engine.
12
To maximize operating efficien­cy, do not run the engine for lon­ger than 30 seconds at a time at full throttle.
To avoid losing control when cut is complete, do not put pressure on saw at end of cut.
Stop the engine before setting the
saw down after cutting.
TREE FELLING TECHNIQUES
WARNING: Check for broken or
dead branches which can fall while cut­ting causing serious injury. Do not cut near buildings or electrical wires if you do not know the direction of tree fall, nor cut at night since you will not be able to see well, nor during bad weather such as rain, snow, or strong winds, etc. If the tree makes contact with any utility line, the utility company should be noti­fied immediately.
Carefully plan your sawing operation in advance.
Clear the work area. You need a clear area all around the tree so you can have secure footing.
The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.
Study the natural conditions that can cause the tree to fall in a particular di­rection.
Natural conditions that can cause a tree to fall in a particular direction include:
The wind direction and speed.
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.
Weight and branches on one side.
Surrounding trees and obstacles.
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 fall on you while cutting. 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 a clear retreat path to the rear and diagonal to the line of fall.
Direction of Fall
45_
Plan a clear retreat path
FELLING LARGE TREES
(6 inches (15 cm) in diameter or larger)
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.
NOTE: If the tree has large buttress roots, remove them before making the notch. If using saw to remove buttress roots, keep saw chain from contacting ground to prevent dulling of the chain.
NOTCH CUT AND FELLING THE TREE
Make notch cut by cutting the top of the notch first. Cut through 1/3 of the diameter 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.

Hinge
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 (5 cm) 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.

NOTE: Before felling cut is complete, use wedges to open the cut if necessary to control the direction of fall. To avoid kickback and chain damage, use wood or plastic wedges, but never steel or iron wedges.
Be alert to signs that the tree is ready to fall: cracking sounds, widen­ing of the felling cut, or movement in the upper branches.
As tree starts to fall, stop saw, put it down, and get away quickly on your planned retreat path.
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 size.
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.
IMPORTANT POINTS
Cut only one log at a time.
Cut shattered wood very carefully;
sharp pieces of wood could be flung toward operator.
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.
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.
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. 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.

Turn saw OFF and use a plastic or wooden wedge to force cut open.
Overcutting begins on the top side of the log with the bottom of the saw against the log. When overcutting use light downward pressure.
Overcutting
Undercutting
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 up-
side down to undercut. The saw can­not be controlled in this position. Always make your first cut on the com­pression side of the log. The compres­sion side of the log is where the pres­sure of the log’s weight is concentrated.

BUCKING WITHOUT A SUPPORT
Overcut through 1/3 of the diameter of the log.
Roll the log over and finish with a second overcut.
Watch for logs with a compression side to prevent the saw from pinch­ing. See illustrations for cutting logs with a compression side.
BUCKING USING A LOG OR SUPPORT STAND
Remember your first cut is always on the compression side of the log. (Refer to the illustrations below for your first and second cut)
Your first cut should extend 1/3 of the diameter of the log.
Finish with your second cut.

LIMBING AND PRUNING
WARNING: Be alert for and
guard against kickback. Do not allow the moving chain to contact any other branches or objects at the nose of the guide bar when limbing or pruning. Allowing such contact can result in serious injury.
WARNING: Never climb into a
tree to limb or prune. Do not stand on ladders, platforms, a log, or in any posi­tion which can cause you to lose your balance or control of the saw.
IMPORTANT POINTS
Work slowly, keeping both hands firmly gripped on the saw. Maintain secure footing and balance.
Watch out for springpoles. Springpoles are small size limbs which can catch the saw chain and whip toward you or pull you off balance. Use extreme cau­tion when cutting small size limbs or slender material.
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.
Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them.
LIMBING
Always limb a tree after it is cut down. Only then can limbing be done safely and properly.
Leave the larger limbs underneath the felled tree to support the tree as you work.
Start at the base of the felled tree and work toward the top, cutting branches and limbs. Remove small limbs with one cut.
Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting.
Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT.
Always use an overcut to cut small and freely hanging limbs. Undercut­ting could cause limbs to fall and pinch the saw.
15
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.
Make your first cut 1/3 of the way through the bottom of the limb.
Next make a 2nd cut all the way through the limb. Then cut a third
overcut leaving a 1 to 2 inch (2.5 to 5 cm) collar from the truck of the tree.

GENERAL RECOMMENDATIONS
The warranty on this unit does not cov­er items that have been subjected to operator abuse or negligence. To re­ceive full value from the warranty, the operator must maintain unit as instructed in this manual. Various adjustments will need to be made peri­odically to properly maintain your unit.
Once a year, replace the spark plug, air filter, and check guide bar and chain for wear. A new spark plug and air filter assures proper air-fuel mixture and helps your engine run better and last longer.
CHECK FOR DAMAGED OR WORN PARTS
Contact your Sears Service Center for replacement of damaged or worn parts. NOTE: It is normal for a small amount of oil to appear under the saw after engine stops. Do not confuse this with a leaking oil tank.
ON/STOP Switch -- Ensure ON/STOP
switch functions properly by moving the switch to the STOP position. Make sure engine stops; then restart engine and continue.
Fuel Tank -- Do not use saw if fuel tank shows signs of damage or leaks.
Oil Tank -- Do not use saw if oil tank shows signs of damage or leaks.

7. Use the screwdriver end of the bar tool to move chain around guide bar.
8. If chain does not rotate, it is too tight. Slightly loosen bar nuts and loosen chain by turning the adjust­ing screw1/4turn counterclock­wise. Retighten bar nuts.
9. If chain is too loose, it will sag be­low the guide bar. DO NOT operate the saw if the chain is loose.
NOTE: The chain is tensioned correctly when the weight of the chain does not cause it to sag below the guide bar (with the chain saw sitting in an upright position), but the chain still moves freely around the guide bar.
WARNING: If the saw is operated
with a loose chain, the chain could jump off the guide bar and result in serious injury to the operator and/or damage the chain making it unusable. If the chain jumps off the guide bar, inspect each drive link for damage. Damaged chain must be repaired or replaced.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING.
CHECK GUIDE BAR
Conditions which require guide bar maintenance:
Saw cuts to one side or at an angle.
Saw has to be forced through the cut.
Inadequate supply of oil to bar/chain.
Check the condition of guide bar each time chain is sharpened. A worn guide bar will damage the 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:
Move ON/STOP switch to STOP.

COOLING SYSTEM
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of:
Air intake on the starter
Air guide plate
Fins on the flywheel
Cooling fins on the cylinder
Cylinder cover (directs cold air over
the cylinder) Clean the cooling system with a brush after each use, more often in demand­ing conditions. A dirty or blocked cool­ing system results in the machine overheating which causes damage to the piston and cylinder.
CHECK CHAIN BRAKE
See CHAIN BRAKE in the OPERATION section.
CLEAN 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 the life and performance of the engine and in­creases fuel consumption and harmful emissions. Always clean your air filter after 10 tanks of fuel or 5 hours of op­eration, whichever comes first. Clean more frequently in dusty conditions. A used air filter can never be completely cleaned. It is advisable to replace your air filter with a new one after every 50 hours of operation, or annually, which­ever comes first.
