9. Install the spark plug carefully, by hand, to avoid cross-threading.
10. After a new spark plug has been seated by hand, it should be tightened 1/2 turn with a wrench to
compress its washer. If a used plug is being reinstalled, it should only require 1/8 to 1/4 turn after
being seated.
11. Reinstall the spark plug cap on the spark plug securely.
12. Reinstall the spark plug maintenance cover.
• The spark plug must be securely tightened. An improperly tightened plug can become very hot and possibly
damage the generator.
• Never use a spark plug with an improper heat range.
• Always use an A7RTC resistor-type spark plug. Using a non-resistor spark plug will interfere with AC output
and the electronics, and may prevent the engine from starting.
