GUARD AGAINST KICKBACK
Follow all safety rules to help avoid kickback and other forces which can result in serious injury.
Kickback Path
Avoid Obstructions
Clear The WorkingArea
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
RotationalKickback 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 i n stant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back toward the operator.
S
Pinch-Kickbackcan 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 i n the opposite direction of the chain rotation. The saw is driven straight back toward the operator.
S
Pull-Incan 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.
REDUCETHE CHANCEOF 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 object at the tip of the guide bar.
S
Keep 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 cutting.
S
When cutting a branch, do not let the guide bar contact another branch or other objects around it.
S
Keep saw chain sharp and properly tensioned. A loose or dull chain can
4
Page 5
increase the chance of kickback. Follow manufacturer’s chain sharp­ening and maintenance instructions. Check tension at regular intervals, but never with engine running. Make sure chain brake nuts are securely tightened.
S
Begin and continue cutting at full speed. If the chain is moving at a slower speed, there is greater chance of kickback occurring.
S
Use extremecaution when reenter­ing a 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 specified Reduced-Kickback Guide Bar and Low-Kickback Chain.
Avoid Pinch-Kickback:
S
Be extremely aware of situations or obstructions 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 saw as bar is withdrawn 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.
MAINTAINCONTROL
Stand to the left of the saw
Thumb on underside of handlebar
Elbow locked
Never reverse hand positions
S
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.
S
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. Stand slightly to the left side of the saw to keep your body frombeing in a direct line with the cutting chain.
S
Stand with your weight evenly bal­anced on both feet.
S
Do not overreach. You could be drawn or thrown offbalance and lose control.
S
Do not cut above shoulder height. It is difficult to maintain control of saw above shoulder height.
KICKBACKSAFETY FEATURES
WARNING:
The following fea­tures are included on your saw to help reduce 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.
S
Front Hand Guard: 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: 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.
S
Reduced-Kickback Guide Bar: de­signed with a small radius tip which reduces the size of the kickback dan­ger zone. This type bar has been demonstrated to significantly reduce the number and seriousness of kick­backs.
Small Radius Tip Guide Bar
Large Radius Tip Guide Bar
S
Low-Kickback Chain: has met kick­back performance requirements when tested on a representative sample of chain saws below 3.8 cubic inch dis­placement.

Kick­backis a lightningfastactionwhichthrows thebar and rotatingchain back and up to­ward the operator. Kickback can be causedby allowingcontact of the bar tip in the danger zone with any hard object. Kickback can also be caused bypinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back towardthe operator. Either of these events may cause you to lose con­trolofthesawwhichcould result in serious injury oreven death.
ANY OF THE SAFETYDEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY T O AVOID KICKBACK.
DO NOT RELYUPON
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 baras origi­nal equipment.

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 safety devices built into your saw.
WARNING:
Computed kickback angle (CKA) listed on your saw and listed in the CKA table below represents angle of kickback your bar and chain combinations will have when tested in accordance with CSA (Canadian Stan­dards Association) standards. When purchasing replacement bar and chain, considerations should be given to the lower CKA values. Lower CKA values represent safer angles to the user, high­er values indicate more angle and high­er kick energies. Computed angle repre­sented indicates total energy and angle associated without activation of the chain brake during kickback. In all cases lower CKA values represent a safer op­erating environment for the user.
The following guide bar and chain com­binations meet kickback requirements of CSA Z62.1 and Z62.3when used on saws listed in this manual. Use of bar and chain combinations other than those listed is not recommended and maynot meettheCKArequirementsper standard.

BEFORE STARTINGENGINE
WARNING:
Be sure to read the fuel handling information in the safety rules section of this manual before you begin. Ifyou do not understand the fuel handling information do not at­tempt to fuel your unit. Seek help from someone that does understand the in­formation or contact your Sears Ser­vice Centre.
GUIDE BAR AND CHAIN OIL
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 Craftsmanbar oil is not available, you may use a good grade SAE 30 oil until you are able to obtain Craftsmanbrand. The oil output is automatically meteredduring 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. This engine is certified to operate on un­leaded gasoline. Before operation, gaso-
line must be mixed with a good quality synthetic 2-cycle air-cooled engine oil. We recommend Craftsman brand syn­thetic oil. Mix gasoline and oil at a ratio of 40:1. A 40:1 ratio is obtained by mix­ing 3.2 ounces (95 ml) of oil with 1 gal­lon (4 litres) of unleaded gasoline. In­cluded with this saw is a 3.2 ounce (95 ml) container of Craftsman brand oil. Pour the entire contents of this container into 1 gallon (4 litres)of gasoline to achieve the proper fuel mixture.
USE
automotive oil or marine oil. These
DO NOT
oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Once oil is added to the 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.
IMPORTANT
Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attractmois­ture 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, the fuel system should be emptied before stor­age for30 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. See
STORAGE
instructions for addition-
al information.

Page 9
Never use engine or carburetor clean­er products in the fuel tank or perma­nent damage may occur. See the
STORAGE
section for addition-
al information.
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 referto

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 inch (0.5 mm) thick. Repairs on a chain brake should be made by your Sears Service Centre.Takeyour unit to the place of pur­chase or to the nearest Sears Service Centre.
S
This saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs.
S
The inertia--activated chain brake is ac­tivated if the front hand guard is pushed forward, either manually (by hand) or automatically (by sudden movement).
S
If the brake is already activated, it is dis­engaged by pulling thefronthandguard back toward the front handle as far as possible.
S
When cutting with the saw, the chain brake must be disengaged.

WARNING:
When performing the following procedure, the engine must be turned off.
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 w eight of the saw to let the tip of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.
OPERATINGTIPS
S
Check chain tension before first use and after 1 minute of operation. See
CHAIN TENSION
MAINTENANCE
in the
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 thefollowing steps.This will help you 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 wearcan occur.
S
To avoid losing control when cut is complete, do not put pressure on saw at end of cut.
S
Stop engine before setting saw down.
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.
S
Carefully plan your sawing operation in advance.
S
Clear the work area. You need a clear area all around the tree so you can have secure footing.
10
Page 11
S
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.
S
Study the natural conditions that can cause the tree to fall in a particular direction. These conditions i nclude:
S
The wind direction and speed.
S
The lean of the tree. The lean of a tree might not be apparentdue 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.
S
Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator.
S
Make sure there is enough room for the tree to fall. Maintain a distance of
2-1/2
tree lengths from the nearest person or other objects. Engine noise can drown out a warning call.
S
Remove dirt,stones, loose bark, nails, staples, and w ire from the tree where cuts are to be made.
Plan a clear retreat path
Direction of Fall

FELLING LARGE TREES
(6 inches 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 tofall in the direction of the notch.
NOTE: If treehas 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 TREE
S
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. See illustration. Once the notch is cut, re­move the wedge of wood from tree.
First cut

NOTE: Before felling cut is complete, use wedges to open the cut when necessary to control the direction of fall. To avoid kickback and 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 ofthe 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 retreatpath.

use your saw to cut down a partially fallen tree.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.
CUTTINGA FALLENTREE (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.

IMPORTANTPOINTS
t
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 logs into a clear area before cutting them.
BUCKINGTECHNIQUES
WARNING:
If saw becomes pinched or hung in a log, don’t tryto 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 saw and carefully reenter the cut. Do not use a metal wedge. Do not at­tempt to restart your saw when it is pinched or hung in a log.
Use a wedge to remove pinchedsaw
Turnsaw 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.

Undercuttinginvolves 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.
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.

LIMBINGAND PRUNING
WARNING:
Be alert forand 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.
IMPORTANTPOINTS
S
Watch out for springpoles. Springpoles are small size limbs which can whip towardyou, or pull you offbalance. Use extreme cau­tion when cutting small size limbs.
S
Be alert forspringback. 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
Frequently clear branches out of the way to avoid tripping over them.
LIMBING
S
Limb a tree only after it is cut down.
S
Leave the larger limbs underneath the felled tree to support the tree as you work.
S
Startat the base of the felled tree and work toward the top, cutting branches and limbs. Remove small limbs withone cut.
S
Keep the tree between you and the chain.
S
Remove larger,supporting branches with the cutting techniques described
BUCKING WITHOUT A SUPPORT.
in
S
Always use an overcut to cut small and freely hanging limbs. Undercut­ting could cause limbs to fall and pinch the 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 first cut
1/3
of the way through the bottom of the limb. This cut will make the limb sag so that it falls easily on the second cut.
S
Next make a second cut an overcut
all the way through the limb.
S
Finish the pruning operation by using an overcut so that the stump of the limb protrudes 1 to 2 inches from the trunk of the tree.

GENERALRECOMMENDATIONS
The warranty on this unit does not cov­er items that have been subjected to operator abuse or negligence. To re­ceive full value fromthe warranty, the operator must maintain unit as instruct­ed in this manual. Various adjustments will need to be made periodically to properly maintain your unit.
S
Once a year, replace the spark plug, air filter element, and check guide bar and chain for wear. A new spark plug and air filter element assures proper air-fuel mixture and helps your engine run better and last longer.
CHECK FOR DAMAGEDOR WORN PARTS
Contact your Sears Service Centre 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.
