4) Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark
plug with a wire brush if it is to be reused.
5) Measure the plug gap with a feeler gauge. Correct as necessary by carefully bending the side
electrode.
The gap should be: 0.70-0.80 mm (0.028-0.031 in).
6) Check that the spark plug washer is in good condition, and thread the spark plug in by hand to
prevent cross-threading.
7) After the spark plug is seated, tighten with a spark plug wrench to compress the washer. If
installing a new spark plug, tighten I/2 turn after the spark plug seats to compress the washer. If
reinstalling a used spark plug, tighten I/8 -1/4 turn after the spark plug seats to compress the
washer.
NOTICE
The spark plug must be securely tightened. An improperly tightened spark plug can
become very hot and could damage the engine. Never use spark plugs which have an
improper heat range. Use only the recommended spark plugs or equivalent.

When transporting the generator, turn the engine switch and the fuel valve OFF. Keep the
generator level to prevent fuel spillage. Fuel vapor or spilled fuel may ignite.
Not turn the machine to any side, and keep the machine under horizontal position during the
transporting process.
