Instructions

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.

Shut off the engine before setting the chain saw down.

•

• 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 engine and thoroughly inspect for damage. Repair as necessary.

• Keep the handles dry, clean and free of the oil/fuel mixture

• 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.

• Use the right tool. Only use this chain saw for its intended purpose, to cut wood.

• Do not overreach. Always keep proper footing and balance.

• Always hold the unit with both hands when operating. Keep a firm grip on all handles or grips.

• 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 engine 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.

KICKBACK SAFETY PRECAUTIONS

WARNING:

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 result 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.

• 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 engine 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 engine 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.

KICKBACK SPECIFICS

Beware of:

Pinch Kickback

A = Pull B = Solid objects C = Push

KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when 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 toward the operator.

PINCHING the saw chain along the BOTTOM of the guide bar may PULL the saw forward away from the operator. PINCHING the saw chain along the TOP of the guide bar may PUSH the guide bar rapidly back toward the operator.

Any of these reactions may cause you to lose control of the saw, which could result in serious personal injury.

OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate. It forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 60 days old).

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• Always use the fresh fuel mix explained in your

operator's manual

• Always agitate the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing

the unit

Using Fuel Additives

The bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit.

If unavailable, use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL®Gas Stabilizer or an equivalent. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel according to the instructions on the container. NEVER add fuel additives directly to the unit's fuel tank.

CAUTION:

maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

For pr operation and

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios.

NOTE: One gallon (3.8 liters) of unleaded gasoline mixed

with one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio.

lever (C)] firmly (Fig. 10).

Chain Lubrication

Adequate lubrication of the saw chain is essential at all times to minimize friction with the guide bar. Never starve the bar and chain of oil. Running the saw with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and cause excessive wear of bar from overheating. Too little oil is evidenced by

Fig. 8

smoke, bar discoloration or pitch build-up.

Automatic Oiler

Your chain saw is equipped with an automatic gear driven oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. As the engine speed increases, so does the oil flow to the bar pad. The amount of oil flowing to the bar and chain may be changed by turning the adjustment screw (D) as shown in Fig. 11. Turn the screw clockwise to DECREASE oil flow and counterclockwise to INCREASE the flow.

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. 12.

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. 14).

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. 16). 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. 17).

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. 18).

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. 19).

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. 19

BUCKING USING A SAWHORSE

For personal safety and ease of cutting, the correct position for vertical bucking is essential (Fig. 20).

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.

While the saw is cutting, be sure the

injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start.

A good preventive maintenance program of regular inspection and care will increase life and improve performance of your chain saw. This maintenance checklist is a guide for such a program.

Cleaning, adjustment, and part replacement may be required, under certain conditions, at more frequent intervals than those indicated.

MAINTENANCE AND REPAIR INSTRUCTIONS

INSTALL THE GUIDE BAR

CAUTION:

USE THE ORIGINAL STYLE BAR with the oil passage hole (A) as illustrated in Fig. 21.

1. Make sure the Chain Brake® lever is pulled back into the DISENGAGED position (Fig. 21).

2. Remove the 2 bar retaining nuts (B) at front of the Chain Brake® cover (C). Remove outer guide bar plate (M, Fig. 27) by pulling straight out (Fig. 22).

Fig. 21

To ensure the bar and chain receive oil, ONLY

INSTALL THE SAW CHAIN

WARNING:

when handling the saw chain.

1. Spread chain out in a loop with cutting edges (E) pointing CLOCKWISE around loop (Fig. 24).

2. Slip the chain around the sprocket (F) behind the clutch (G). Make sure the links fit between the sprocket teeth (Fig. 25).

3. Guide the drive links into the groove (H) and around the end of the bar (Fig. 25).

4. The chain will be tight so you will have to rotate the clutch clockwise by hand so the chain engages the bar sprocket.

5. Replace the outer guide bar plate (I) so the bent edges (top and bottom) are directed away from the chain (Fig. 27).

6. Install spike on Chain Brake® cover as shown in Fig. 27 (Optional accessory).

7. Install the Chain Brake® cover (Fig. 27). Make sure the chain does not slip off of the bar. Install the 2 nuts hand tight and follow instructions in Tension Adjustment.

NOTE: The guide bar retaining nuts are installed only

hand tight at this point because saw chain adjustment is required. Follow instructions in Saw Chain Tension Adjustment.

Always use protective gloves
