will cause engine damage. When mixing fuel follow the instructions printed on the container. 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 attract moisture 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, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the en- gine and let it run until the fuel lines and carbu- retor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner prod- ucts in the fuel tank or permanent damage may occur.

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 refer to CAR- BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns.

To stop the engine, move the ON/STOP switch to the STOP position.

To start the engine, hold the saw firmly on the ground as illustrated below. Make sure the chain is free to turn without contacting any object.

Use only 15! ---18!of rope per pull. Hold saw firmly while pulling starter rope

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 cut material with the choke/fast idle le- ver at the FULL CHOKE position.

STARTING A COLD ENGINE (or a warm engine after running out of fuel)

NOTE: In the following steps, when the cho- ke/fast idle lever is pulled out to the full ex- tent, the correct throttle setting for starting is set automatically.

1.Move ON/STOP switch to the ON posi- tion.

2.Pull the choke/fast idle lever out to the full extent.

3.Slowly press the primer bulb 6 times.

4.Pull the starter rope quickly with your right hand 5 times; then push the choke/ fast idle lever in completely (to the OFF CHOKE position).

5.Pull the starter rope quickly with your right hand until the engine starts.

6.Allow the engine to run for approximately 5 seconds. Then, squeeze and release the throttle trigger to release the fast idle, allowing the engine to idle.

2.Pull the choke/fast idle lever out to the full extent to set the throttle, then return the choke/fast idle lever to the OFF CHOKE position.

3.Pull the starter rope quickly with your right hand until the engine starts.

4.Squeeze and release the throttle trigger to release the fast idle, allowing the en- gine to idle.

STARTING A FLOODED ENGINE

The engine may be flooded with too much fuel if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by fol- lowing the warm engine starting procedure listed above. Insure the ON/STOP switch is in the ON position. Starting could require pulling the starter rope handle many times depending on how badly the unit is flooded. If engine fails to start refer to the TROUBLE-

SHOOTING TABLE.

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 should be replaced by an authorized service dealer if any part is worn to less than 0,02! (0,5 mm) thick. Repairs on a chain brake should be made by an authorized ser- vice dealer. Take your unit to the place of pur- chase if purchased from a servicing dealer, or to the nearest authorized master service dealer.

SThis saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs.
