BAR AND CHAIN LUBRICATION

season. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar.

Only use Bar and Chain Oil for bar and chain lubrication.

STARTING

STARTING 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. Make sure the chain is free to turn without contacting any object.

Use only 40 --- 45 cm 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.

NOTE: Do not cut material with the choke/ fast idle lever at the FULL CHOKE position.

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

NOTE: In the following steps, when the choke/fast idle lever is pulled out to the full extent, 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 (to the FULL CHOKE position).

3.Pull starter rope sharply with your right hand a maximum of 10 times. Then, pro- ceed to the next step.

NOTE: If the engine sounds as if it is trying to start before the 10th pull, stop pulling and immediately proceed to the next step.

4.Push the choke/fast idle lever in to the HALF CHOKE position.

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

6.Allow the engine to run for approximately 5 seconds. Then, squeeze and release throttle trigger to allow engine to return to idle speed.

STARTING A WARM ENGINE

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

2.Pull the choke/fast idle lever out to the HALF CHOKE position.

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

4.Squeeze and release the throttle trigger to allow engine to return to idle speed.

DIFFICULT STARTING (or starting a flooded engine)

The engine may be flooded if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by following the warm engine starting procedure listed above. Ensure the ON/STOP switch is in the ON position. Starting could require many pulls depending on how badly unit is flooded. If engine still fails to start, refer to the TROUBLESHOOTING TABLE.
