MUFFLER AND SPARK ARRESTING SCREEN WARNING: The muffler on this product contains chemicals known to the State of California to cause cancer. As your unit is used, carbon deposits build up on the muffler and spark arresting screen. For normal homeowner use, however, the muffler and spark arresting screen will not require any service. After 50 hours of use, we recommend that your muffler be serviced or replaced by your authorized service dealer. REPLACE SPARK PLUG Replace the spark plug each year to ensure the engine starts easier and runs better. Inspect spark plug every 25 hours of usage. Clean and/or replace as necessary.

CHAIN SHARPENING WARNING: Improper chain sharpening techniques and/or depth gauge maintenance will increase the chance of kickback which can result in serious injury. WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. Conditions which indicate the need for chain sharpening: S Reduction in size of wood chips. The size of the wood chip will decrease as the chain gets duller until it becomes more like a powder than a chip. Note that dead or rotted wood will not produce a good chip. S Saw cuts to one side or at an angle. S Saw has to be forced through the cut. Tools required: S 3/16 inch (4,5 mm) diameter round file and file holder S Flat file S Depth gauge tool 18 TO SHARPEN CHAIN: 1. Disconnect spark plug. 2. Check chain for proper tension. Adjust chain tension if necessary. See CHECK CHAIN TENSION section. 3. Sharpen cutters.
