MAINTENANCE
IDLE SPEED ADJUSTMENT
See Figure 21.
If the chain turns at idle, the idle speed screw needs adjusting on the engine. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the chain movement. If the saw chain still moves at idle speed, contact a service dealer for adjustment and discontinue use until the repair is made.
WARNING:
The saw chain should never turn at idle. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the chain, or contact a service dealer for ad- justment and discontinue use until the repair is made. Serious personal injury may result from the saw chain turning at idle.

CHAIN OILER
See Figure 22.
Use Premium Bar and Chain Oil. It is designed for chains and chain oilers and is formulated to perform over a wide temperature range with no dilution required.
Remove the cap and carefully pour approximately 8 oz. of bar and chain oil into the chain oiler tank.
Replace the cap and tighten securely.
Check and refill the chain oiler tank every time the engine is fueled.
NOTE: Do not use dirty, used or otherwise contaminated oils. Damage may occur to the oil pump, bar, or chain.

CHAIN MAINTENANCE
See Figure 23.
For smooth and fast cutting, the chain needs to be main- tained properly. The following conditions indicate that the chain requires sharpening:
Wood chips are small and powdery
Chain must be forced through the wood during cutting
Chain cuts to one side
During maintenance of the chain, consider the following:
Improper filing angle of the side plate can increase the risk of a severe kickback.
Depth gauge (or raker clearance) setting determines the height the cutter enters the wood and the size of the wood chip that is removed. Too much clearance increases the potential for kickback. Too little clearance decreases the size of the wood chip thus decreasing the chain's cutting ability.
If cutter teeth have hit hard objects such as nails and stones, or have been abraded by mud or sand on the wood, have service dealer sharpen chain.
