Maintenance
Spark Plugs
Inspect spark plugs after the break-in period and every
15,000 miles (24,000 km) thereafter. Replace spark plugs
every 30,000 miles (48,000 km). Always replace spark plugs
in pairs.
1. Make sure the engine has cooled to room temperature.
2. Turn the power switch off.
3. Pull upward on the spark plug boots (not the wires) to
remove the boots.
CAUTION! Wear eye and face protection when using pressurized
air.
4. To prevent debris from entering the spark plug holes,
use compressed air to clean the area around the plugs
before removing them.
Tool: 12 mm plug socket
Tip: Both spark plugs should have the same light or medium tan
color deposits. The electrodes should be square with sharp
edges.
5. Reinstall the spark plugs or install new plugs.
6. Reinstall the spark plug boots.
