4.
Visually inspect the spark plug. Discard
it if the insulator is cracked, chipped or
fouled.
5.
Measure the plug gap with a feeler
gauge. Correct as necessary by carefully
bending the side electrode. The gap
should be: 0.028 to 0.031 in (0.70 to
0.80 mm)
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 1/2 turn after the spark plug
seats to compress the washer. If reinstalling a used spark plug, tighten
1/8 to 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. Use
only the recommended spark plugs or equivalent.
Optional Spark Arrestor Maintenance
If the generator has been running, the muffler will be very hot. Allow
it to cool before proceeding. The spark arrestor must be serviced
every 50 hours to keep it functioning as designed.
Clean the spark arrestor as follows:
1.
Loosen the screw by the exhaust port of the muffler and remove
the spark arrestor.
2.
Use a brush to remove carbon deposits from the spark arrestor
screen. Inspect the screen for breaks or tears and replace it if
necessary.
3.
Install the spark arrestor in the reverse order of removal.

not place heavy objects on the generator. When transporting the
generator by loading it on to a vehicle, secure to the generator frame
DANGER
Contact with a hot engine or
exhaust system can cause seri-
ous burns or fires. Let the en-
gine cool before transporting or
storing the generator.
