hearing. Regular users should have hearing checked regularly as chainsaw noise can damage hearing. Secure hair above shoulder length.

Keep all parts of your body away from the chain when the engine is running. Keep children, bystanders, and animals a minimum RIPHWHUVIHHWDZD\IURPWKHZRUNDUHD'R not allow other people or animals to be near the chainsaw when starting or operating the chainsaw. Do not handle or operate a chainsaw 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. Chainsaw work is strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a chainsaw. Carefully plan your sawing operation in advance. Do not start cutting until you have a clear work area, secure footing, and, if you are felling trees, a planned retreat path.

Do not operate a chainsaw with one hand. Serious injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed operation. A chainsaw is intended for two-handed use. Operate the chainsaw only in a well-ventilated outdoor area. Do not operate saw from a ladder or in a tree.

0DNHVXUHWKHFKDLQZLOOQRWPDNHFRQWDFWZLWKDQ\ 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 the engine before setting the saw down. Do not operate a chainsaw 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.

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 chainsaw control. ROTATIONAL KICKBACK 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 Pinch kickback can occur when 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 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.

REDUCING 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 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, QHYHUZLWKWKHHQJLQHUXQQLQJ0DNHVXUHWKHEDU nuts are securely tightened after tensioning the chain. Begin and continue cutting at full speed. If the chain is moving at a slower speed, there is greater chance of kickback occurring. Use wedges made of plastic or wood. Never use metal to hold the cut open. Cut one log at a time.

KICKBACK SAFETY FEATURES

a WARNING! The following features are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this danger. As a chainsaw 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.

REDUCED KICKBACK GUIDE BAR

The reduced-kickback guide bar is designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip. LOW-KICKBACK CHAIN A low-kickback chain is designed with a contoured GHSWKJDXJHDQGJXDUGOLQNZKLFKGHÀHFWNLFNEDFN force and allow wood to gradually ride into the cutter.

downward pressure. If you force the cut, damage to the guide 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, guide bar, and engine. It is recommended that the engine QRWEHRSHUDWHGIRUORQJHUWKDQVHFRQGVDWIXOO 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.

PLANNING a 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

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 chainsaw 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. 0DNHVXUHWKHUHLVHQRXJKURRPIRUWKHWUHHWRIDOO 0DLQWDLQDGLVWDQFHRIWUHHOHQJWKVIURPWKH nearest person or other objects.

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. 0DNHWKHQRWFKFXWE\FXWWLQJWKHWRSRIWKHQRWFK

complete the notch by cutting the bottom of the notch. Once the notch is cut remove the notch of wood from the tree. After removing the wood from the notch, make the felling cut on the opposite side of the notch. This is GRQHE\PDNLQJDFXWDERXWFHQWLPHWHUVLQFKHV 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.

(BUCKING) Bucking is the term used for cutting a fallen tree to the desired log size. a 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. ,03257$1732,176 Cut only one log at a time. Cut shattered wood very carefully; sharp pieces of ZRRGFRXOGEHÀXQJWRZDUGRSHUDWRU 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

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.

TYPES OF BUCKING CUTS

Overcutting begins on the top side of the log with the bottom of the saw against the log. When overcutting use light downward pressure. Undercutting involves cutting on the underside of the log with top of saw against the log. When undercutting

a 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. a 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. 12,03257$1732,176

Avoid being struck by the branch or the saw when the tension LQWKHZRRG¿EHUVLVUHOHDVHG 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. PRUNING a 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.

CHECK FOR DAMAGED OR WORN PARTS

Contact an authorized service dealer 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 SRVLWLRQ0DNHVXUHHQJLQHVWRSVWKHQUHVWDUW 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.

CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING. 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 DQGPDNHFXWWLQJGLI¿FXOW After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole.

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

&\OLQGHUFRYHUGLUHFWVFROGDLURYHUWKHF\OLQGHU 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. 15CHAIN SHARPENING The cutter The cutting part of the saw chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two, the depth gauge setting (C). When you sharpen a cutting tooth there are four important factors to remember:
