RULES FOR SAFE OPERATION

KICKBACK SPECIFICS

WARNING:

control of the chain saw and result in serious or fatal injury to the saw operator or to anyone standing close by. Always be alert. Rotational kickback and pinch-kickback are major chain saw operational dangers and the leading cause of most accidents.

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.

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

Kickback can lead to dangerous loss of

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.

KICKBACK SPECIFICS Pinch Kickback

Pinch kickback can occur when the saw chain is pinched along the bottom or top of the guide bar

When pinched on the bottom of the guide bar, it may pull the saw forward, away from the operator

When pinched along he top of the guide bar, it may push the guide bar rapidly back toward the operator.

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 (less than 60 days old) clean unleaded fuel. Follow the instructions car

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 and lead to formation of acids during storage. When using alcoholblended fuel, use fresh fuel.

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow r

• Always use the fresh fuel mix explained in your opera-

• Always shake the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing the

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.

WARNING: Be sure to read the Oil and Fuel Information

Section

understand the oil and fuel information, do not attempt to fuel your unit. For more information contact your local Sears service center at 1-800-4-MY-HOME®.

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 with smoke coming from the chain and 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 the 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 THE ENGINE WARNING: Remove fuel cap slowly when refueling.

This engine is certified to operate on unleaded gasoline. Befor 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. 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline. Included with this saw is a 3.2 ounce container of oil. Pour the entire contents of this container into one gallon of gasoline to achieve the proper fuel mixture. DO NOT use automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow the instructions printed on the oil 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 with fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine when in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner products in the fuel tank or permanent damage can occur. See STORAGE instructions for additional information.

CHAIN BRAKE

Be sure the 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 brake must not move when the engine runs at idle speed. If the chain brake moves at idle speed, refer to CARBURETOR ADJUSTMENT in this manual. Avoid contact with the muffler. A hot muffler can cause serious burns.

IMPORTANT POINTS TO REMEMBER

When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly. For cold weather starting, start the unit at FULL CHOKE; allow the engine to warm up before squeezing the throttle trigger.

DO NOT attempt to cut material with the choke/fast idle lever in the FULL CHOKE position.

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 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) with a small slotted scr

ewdriver as shown in Fig. 11. Turn the screw clockwise to DECREASE oil flow and counterclockwise to INCREASE the flow.

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.

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.

Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D) (Fig. 13).

Start making the upper notch cut (C) on the side of the tree facing the felling direction (E). Be sure you don t make the lower cut too deep into the trunk (Fig. 13).

The notch (C) should be deep enough to create a hinge (F) of sufficient width and strength. The notch should be wide enough to direct the fall of the tree for as long as possible (Fig. 13).

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).

Log supported on 1 end: First, cut from bottom

2. (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.

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. Place the slotted end of the guide bar over the two bar bolts (D, Fig. 23). Be sure adjusting tang (J, Fig. 23) is in lower adjusting hole of the bar.

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

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

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

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

MAINTENANCE AND REPAIR INSTRUCTIONS

SAW CHAIN TENSION ADJUSTMENT

WARNING:

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.

To adjust the saw chain:

1. Loosen the bar retaining nut(s) (B, Fig. 27). Hold nose of guide bar up and turn adjustment screw (D) CLOCKWISE to increase chain tension. Turning screw COUNTERCLOCKWISE will decrease amount of tension on chain. Ensure the chain fits snugly all the way around the guide bar (Fig. 28).

Fig. 28

2. After making adjustment, and while still holding nose of bar in the uppermost position, tighten the bar retaining nuts securely. Chain has proper tension when it has a snug fit all around and can be pulled around by gloved hand.

NOTE: If chain is difficult to rotate on guide bar or if it

binds, too much tension has been applied. This requires minor adjustment as follows:

A. Loosen the bar retaining nuts so they are hand tight.

Decrease tension by turning the bar adjustment screw COUNTERCLOCKWISE slowly
