Maintenance
Spark Plugs
Replace spark plugs at the intervals recommended in the
periodic maintenance table beginning on page 53.
Always replace spark plugs in pairs.
1. Make sure the engine is at room temperature.
2. Pull upward on the spark plug boot (not the wire) to remove the boot.
CAUTION!
Wear eye and face protection when using pressurized air.
3. To prevent debris from entering the spark plug hole, use compressed air to clean the area
around the plugs before removing them. Remove the spark plugs.
Tool:
5/8-inch plug socket
Tip:
Both spark plugs should have the same light or medium tan color deposits. The electrodes should
be square with sharp edges.
4. Reinstall the spark plugs or install new plugs. Apply anti-seize compound sparingly to
the threads.
