RULES FOR SAFE OPERATION

• Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw’s chain stops moving when the throttle control trigger is released.

Use extreme caution when cutting small-sized brush

• and saplings because slender material may catch the chain saw and whip towards you or pull you off balance.

• When cutting a limb that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released

• Do not cut through nails, rods in the tree, railroad ties or pallates. Inspect a tree that you are going to cut for foreign objects that could cause injury or damage to your chain saw.

• After striking a foreign object, stop the motor and thoroughly inspect for damage. Repair as necessary.

• We do not recommend using the chain saw in a tree or on a ladder.

• All chain saw service, other that the items listed in this instruction manual maintenance instructions, should be performed by competent chain saw service personnel.

• Apply chain brake prior to any repositioning of the operator in the cutting area. As an additional safety precaution, apply the chain brake prior to setting down the saw.

• Never touch the chain or attempt to service the saw while the motor is running. Make sure all moving parts have stopped. Allow the chain saw to cool, as the chain can be hot.

Check the bar and chain at frequent intervals for

• proper adjustment. Make sure the bar and chain are properly tightened and sharpened. Visually inspect for damage. Repair any damage before restarting or operating the chain saw.

WARNING:

KICKBACK may

occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back towards the 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 r esult in serious personal injury .

Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

KICKBACK SAFETY PRECAUTIONS

• With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. Be alert to the potential for kickback at all times.

• Keep a good firm grip on the saw with both hands, the right hand on the rear handle and the left hand on the front handle, when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.

• Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, fence, or any other obstruction that could be hit while you are operating the saw.

• Always cut with the motor running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.

• Use only the correct original equipment manufacturer replacement bars, chains and other parts and accessories. These are available from your authorized service dealer. Use of any unauthorized parts or accessories could lead to serious injury to the user, or damage to the unit, and will void your warranty.

• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.

• Use only the replacement guide bars and low kickback chains specified for your saw to avoid injury.

RULES FOR SAFE OPERATION

OTHER SAFETY PRECAUTIONS

• 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 onehanded operation. A chain saw is intended for twohanded use.

• Do not operate a chain saw if you are fatigued.

• Use safety footwear; snug-fitted clothing; protective gloves; and eye, hearing, and head protection devices.

• Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.

• Do not remove, damage or de-activate any of the safety devices. Never use a damaged, modified, or improperly repaired or assembled chain saw. Check their proper operation regularly. Only use bars and chains of the length indicated in the table herein.

• Never carry out operations or repairs on your own that are other than routine maintenance. For information, contact specialized and authorized workshops only.

• If your chain saw is no longer usable, dispose of it properly without damaging the environment by handing it in to your local dealer who will arrange for its correct disposal.

• Use caution when felling a tree. Make sure you have planned an escape path when felling, and keep all bystanders away.

• Be alert; stop the machine if anyone enters the cutting area, which is usually 3 to 4 feet around the operator.

• Use caution when working in a crew to avoid injury to a fellow worker who may enter the cutting area.

• Only loan your saw to experienced users who are completely familiar with saw operation and correct use. Give other users this manual, which they should read before using the saw. Provide them the operating instructions.

• Shut off the motor before setting down the saw. Do not leave the motor running unattended.

Store the unit in a dry area, locked up, located up high

• and located out of the reach of children to prevent unauthorized use or damage.

• Never douse or squirt the unit with water or any other liquid. Keep handles dry, clean and free from debris. Clean after each use.

• Keep these instructions. Refer to them often and use them to instruct other users. If you loan someone this unit, also loan them these instructions.

• Do not use the unit in the rain, in a storm or in inclement weather. Wait until the storm danger has passed before operation of this product.

ELECTRICAL SAFETY WARNINGS

• Since the tool is double-insulated, a 2-wire extension cord (an extension cord without a ground) may be used. A 3-wire extension cord (an extension cord with a ground) that uses a NEMA type connector (parallel blade, U ground) is recommended. Extension cords are available from your local retailer. Use only roundjacketed extension cords approved for outdoor use.

• This tool is double-insulated. Repair or replace damaged cords.

• To reduce the risk of electrical shock, this unit has a polarized plug (one blade is wider than the other). This unit will fit with a polarized plug in one way only. If the plug does not fit fully into the unit, reverse the plug. If it still does not fit, use a cord with the correct connection. Do not modify the unit in any way.

OPERATING INSTRUCTIONS

FELLING

Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the direction the tree will fall.

WARNING:

and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Fig. 8.

CAUTION:

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.

NOTE: Direction of fall (B) is controlled by the notching

cut. Before any cuts are made, consider the location of larger branches and natural lean of the tree to determine the way the tree will fall.

A retreat path (A) should be planned

Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will prevent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make sure no bystanders have entered the range of the falling tree before you push it over.

Felling Cut:

1. Use wooden or plastic wedges (G) to prevent binding the bar or chain (H) in the cut. Wedges also control felling (Fig. 10).

LIMBING

Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting limbs (A) until after the log is bucked (cut) into lengths (Fig. 12). Branches under tension should be cut from the bottom up to avoid binding the chain saw.

When bucking on a slope, always stand on the uphill side.

1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground (Fig. 13).

2. Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig. 14).

3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering. Second, underbuck to meet first cut and avoid pinching (Fig. 15).

NOTE: The best way to hold a log while bucking is to use

a sawhorse. When this is not possible, the log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log being cut is securely supported.

BUCKING

Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway through the log and then make the undercut. This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain.

Fig. 15

BUCKING USING A SAWHORSE

For personal safety and ease of cutting, the correct position for vertical bucking is essential (Fig. 16).

A. Hold the saw firmly with both hands and keep the

saw to the right of your body while cutting.

B. Keep the left arm as straight as possible. C. Keep weight on both feet.

CAUTION:

chain and bar are being properly lubricated.

MAINTENANCE AND REPAIR INSTRUCTIONS

SAW CHAIN TENSION ADJUSTMENT

WARNING:

when handling the saw chain.

Proper tension of saw chain is extremely important and must be checked before starting, as well as during any cutting operation.

Taking the time to make needed adjustments to the saw chain will result in improved cutting performance and prolonged chain life.

NOTE: A new chain and bar will need readjustment after

as few as 5 cuts. This is normal during the breakin period, and the interval between future adjustments will lengthen quickly (Fig. 22).

CAUTION:

TIGHT, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study Fig. 22 for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C).

To adjust the saw chain: NOTE: Make sure the Chain Brake® is disengaged. Disengage the Chain Brake® (D) by pulling it backward

(Fig. 23).

1. Tensioning the chain can be accomplished with relative ease. Turn bar bolt knob (E) counter clock wise. Then turn ring (F) counter clock wise to loosen chain or clock wise to tighten chain (Fig. 24).

Always use protective gloves

If saw chain is TOO LOOSE or TOO

Fig. 23

2. After adjustment and while wearing heavy duty work gloves, move the saw chain back and forth on the guide bar to be sure the chain moves freely and is in proper mesh with sprocket.

NOTE: If the chain is difficult to rotate or if it binds on the

guide bar, too much tension has been applied and must be adjusted as described in step 1.

3. While applying tension to the chain, hold the tip of the bar up and then tighten the bar bolt knob (E).

MAINTENANCE AND REPAIR INSTRUCTIONS

CHAIN AND BAR LUBRICATION

Adequate lubrication of the saw chain during cutting operations is essential to minimize friction with the guide bar.

Your chain saw is equipped with an automatic oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. There is no flow adjustment.

You can check the oil tank level using the inspection slot (D) provided on the right side of the saw. The tank is full when oil is at the top of the slot (Fig. 25).

Fig. 25

CAUTION:

lubrication oil. Running the saw DRY or with TOO LITTLE OIL will decrease cutting efficiency, shorten chain saw life, and cause rapid dulling of the chain and excessive wear of the bar from overheating. Too little is evidenced by smoke or bar discoloration.

Never starve the bar and chain of

The Chain Brake® is a safety feature which is activated if pressure is applied against the guard or when, in the event of kickback, the operator’s hand strikes the lever. When the Chain Brake® is activated, chain movement abruptly stops and the power supply to the motor is immediately cut off.

The purpose of the Chain Brake® is to reduce the possibility of injury due to kickback. The Chain Brake® cannot, however, provide the measure of intended protection if the saw is carelessly operated.

The Chain Brake® is disengaged (chain can move) when the brake is pulled back and locked. This is the normal running position (Fig. 26).

Fig. 26

The Chain Brake® is engaged (chain cannot move) when the brake is in forward position (Fig. 27).

NOTE: The motor will not start if the Chain Brake® is in

the engaged position.

NOTE: The saw chain stretches during use, particularly

when it is new, and occasional adjustment will be needed. A new chain requires more frequent adjustment during the break-in period. This is normal. See Section Saw Chain Tension Adjustment for instructions.

WARNING:

you are cutting, as well as wear the bar and chain. A chain that is too tight can damage the saw. Either situation, chain too loose or too tight, could cause serious personal injury .

MAINTENANCE AND REPAIR INSTRUCTIONS

GUIDE BAR MAINTENANCE

Frequent lubrication of the guide bar is required. Proper maintenance of the guide bar, as explained in this section, is essential to keep your saw in good working condition.

WARNING:

disconnected before performing any maintenance on your saw.

Sprocket Tip Lubrication

CAUTION:

been pre-lubricated at the factory. Failure to lubricate the guide bar sprocket tip as explained below will result in poor performance and seizure, voiding the manufacturer’s warranty.

Lubrication of the sprocket tip is recommended after each saw use. Always thoroughly clean guide bar sprocket tip before lubrication.

The Lube Gun (optional) is recommended for applying grease to the guide bar sprocket tip. The Lube Gun is equipped with a needle nose tip which is necessary for the efficient application of grease to the sprocket tip.

Maintenance Procedures

Most guide bar problems can be prevented merely by keeping the chain saw well maintained. Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily resulting in uneven bar wear. As the bar wears unevenly, the rails widen, which may cause chain clatter and difficulty in making straight cuts.

Insufficient guide bar lubrication and operating the saw with chain that is too tight will contribute to rapid bar wear.

To help minimize bar wear, the following guide bar maintenance procedures are recommended:

BAR WEAR - Turn guide bar frequently at regular intervals (for example, after 5 hours of use), to ensure even wear on top and bottom of bar.

BAR GROOVES - Bar grooves (or rails which support and carry the chain) should be cleaned if saw has been used heavily or if saw chain appears dirty. Rails should always be cleaned every time saw chain is removed.

OIL PASSAGES - Oil passages on the bar should be cleaned to ensure proper lubrication of the bar and chain during operation. This can be done using a soft wire small enough to insert into the oil discharge hole.

NOTE: The condition of the oil passages can be easily

checked. If the passages are clear, the chain will automatically give off a spray of oil within seconds of starting the saw. Your saw is equipped with an automatic oiler system.

Cleaning Bar Rails

1. Remove sprocket cover, bar and chain. Refer to the Install the Guide Bar/Saw Chain section.

2. Using a screwdriver, putty knife, wire brush or other similar instrument, clear residue from the rails on the guide bar. This will keep the oil passages open to provide proper lubrication to the bar and chain (Fig. 29).

3. Reinstall the bar, chain, sprocket cover and bar bolt knob. See Section Install the Guide Bar / Saw Chain for more information.

To lubricate the sprocket tip:

Unplug the chain saw from the power source.

1. NOTE: It is not necessary to remove the saw chain to

4. Make sure that the Chain Brake® is deactivated.

lubricate the guide bar sprocket tip. Lubrication can be done on the job.

WARNING:

when handling the saw chain.

Using the Lube Gun (optional), insert tip of lube gun into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Fig. 28).

Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has been greased.

Always use protective gloves

MAINTENANCE AND REPAIR INSTRUCTIONS

CHAIN MAINTENANCE

WARNING:

specialized training for dealing with kickback (see Safety Precautions), always use a low-kickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not completely eliminate kickback. A lowkickback or “safety chain”, should never be regarded as total protection against injury.

A low-kickback saw chain should always be used in conjunction with other kickback protection devices such as the Chain Brake®/Hand Guard furnished with your unit.

Always use a replacement saw chain designed as “lowkickback” or a saw chain which meets the low-kickback performance requirements of ANSI (American National Standards Institute).

A standard saw chain (a chain which does not have the kickback reducing guard links) should only be used by an experienced professional chain saw operator.

What is a Low-Kickback Saw Chain?

A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1.

By keeping the Chain Brake® and saw chain in good working condition and correctly serviced as recommended in this manual, you will be able to maintain the safety system of your chain saw over the life of the product.

Chain Tension

Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand.

Breaking in a New Saw Chain

A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly.

Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. This is normal. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. See your Authorized Service Center to have this repair performed.

Unless you have experience and

WARNING:

removed from a loop of chain. This could cause damage to the sprocket.

Never have mor than 3 links

Chain Lubrication

Always make sure the automatic oiler system is working properly. Keep the oil tank filled with Genuine Factory Parts Chain, Bar and Sprocket Oil.

Adequate lubrication of the bar and chain during cutting operations is essential to minimize friction with the guide bar.

Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar discoloration.

Chain Sharpening

Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be professionally sharpened by the nearest Authorized Service Center. If you feel comfortable sharpening your own saw chain, special tools are available from your Authorized Service Center.

WARNING:

inoperative any safety device furnished with your unit. The Chain Brake® / Hand Guard and low-kickback saw chain are major safety features provided for your protection.

Never remove, modify or make
