Engine Maintenance
Spark Plug
For good performance, the spark plug must be properly gapped and free of
deposits. Replace the spark plug annually.
1.
Disconnect the cap from the spark plug, and remove any dirt from the spark
plug area.
2.
Use the proper size spark plug wrench to remove the spark plug.
3.
Visually inspect the spark plug. Discard the spark plug if there is apparent
wear, or if the insulator is cracked or chipped. Clean the spark plug with a
wire brush if it is to be reused.
4.
Check the gap with a wire gauge. See Figure 16. Spark plug gap should be
0.030 in (0.76 mm). If necessary, reset the gap.
5.
Check that the spark plug washer is in good condition and thread the spark
plug in by hand to prevent cross-threading.
6.
After the spark plug is seated, tighten with a spark plug wrench to compress
the washer.
NOTE: When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer. When reinstalling a used spark plug,
tighten 1/8-1/4 turn after the spark plug seats to compress the washer.
IMPORTANT: The spark plug must be securely tightened. An improperly
tightened spark plug can become very hot and may damage the engine.
7.
Attach the spark plug cap to the spark plug.
Air Filter
Paper filters cannot be cleaned and must be replaced once a year or every 100
operating hours; more often if used in extremely dusty conditions.
Never use gasoline or low flash point solvents for cleaning the air filter
element. A fire or explosion could result.
IMPORTANT: Never run the engine without the air filter. Rapid engine wear will
result.
