Spark Plug Maintenance
After every 50 hours clean the spark plug with a brush. If the insulator on the spark plug is damaged replace
it immediately. Check the spark plug gap with a feel gauge, the gap should be 0.7-0.8mm. If adjustment is
necessary bend the side electrode carefully. Check the spark plug gasket is in good condition or replace with a
new one. Screw in the spark plug to the bottom first by hand and then tighten by using a spark plug wrench. If
a new spark plug is used, twist a 1/2 more turn after impacting the gasket. If using the original gasket, twist 1-8
- 1/4 more turn.
Caution:
The spark plug eliminator should be serviced at least once every 100 hours of operation so as to keep it in good
condition.
Warning:
The muffler is very hot hen the engine is running and remains hot for a prolonged period after the engine has
stopped. Only service after the engine cools down completely.
Unscrew two nuts and remove the exhaust elbow from the engine body.
Unscrew five screws from the muffler guard and take it out.
Unscrew from the spark plug eliminator and separate the muffler.
Clean the spark eliminator mesh with a wire brush.
Reinstall the spark plug eliminator in reverse order of removal.
Caution:
Be careful not to damage the spark plug eliminator. Never use a damaged spark eliminator.
