Spark Plug Maintenance
The spark plug is essential for proper engine operation. The spark plug should be intact, free of deposits,
and properly gapped. A bad or incorrectly installed spark plug can cause engine damage. To inspect the spark plug:
1. Remove the spark plug by pulling on the spark plug cap.
2. Unscrew the spark plug from this chainsaw by using the included spark plug wrench.
3. Inspect the spark plug. If it is cracked and/or chipped, install a new spark plug. A RCJ6Y spark plug is recommended.
4. Measure the spark plug electrode gap with a gauge. The gap should be (0.023
-
0.027
inches) (0.6~0.7 mm)
.
5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base and then re-gap the spark plug.
6. Screw the spark plug back into place on this chainsaw by using the included spark plug wrench.
7. Replace the spark plug cap.
Cleaning the Air Filter
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally verify that the air filter is free of excessive dirt. The air filter will
require more frequent cleaning when operating this chainsaw in extremely dusty areas.
To clean the air filter, remove the foam filter element from the chainsaw and wash it in warm water and household dish detergent. Thoroughly rinse and dry. Pour a
small amount of motor oil onto the filter, ring out ALL excess oil, and reinstall the foam filter element in the chainsaw.
To locate the air filter, unscrew the two bolts attaching the bottom air filter cover, located below the choke lever, to access the foam filter element.
Modifying the Carburetor
The carburetor is factory set and CANNOT be modified.
Emptying the Carburetor
To store this chainsaw for extended time, the fuel needs to be drained from the carburetor.
To drain the fuel from the carburetor, turn the fuel valve to the “off” position while the engine is running. The chainsaw will shut down when all the gasoline in the
carburetor has been used.
Do not store gasoline for more than 3 months.
