MAINTENANCE
Use a clean cloth to remove loose dirt from around the fuel tank cap and empty the fuel tank. The fuel
tank cap contains a check valve. If the performance improves when the fuel tank cap is loosened, the
check valve may be faulty. Replace the fuel tank cap if required.
A clogged fuel lter will cause poor engine performance. Replace the fuel lter if required as it is a non-
serviceable part. Please contact your nearest service center for replacing this fuel lter.
SPARK PLUG REPLACEMENT (See Figs. 26-29)
The spark plug for this engine may be replaced using an identical or equivalent spark plug as provided
with the tool. The spark plug gap should be set at 0.026 in. (0.65 mm). Replace annually with a
recommended or equivalent replacement part.
■ Remove the spark plug cap. Fully cover the spark plug using the provided socket wrench. Rotate
the wrench counter clockwise to remove the spark plug (Fig. 26 & 27).
■ Check the spark plug for fouling, worn and rounded center electrode. Clean the plug or replace with
a new one. DO NOT use a blowing tool to clean as the movement of dirt may damage the engine.
■ Adjust spark plug gap by bending outer electrode (Fig. 28).
■ Reinstall the cleaned or new spark plug by turning it clockwise into place (Fig. 29).
