Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it with a dirty air cleaner.
Replace the air cleaner every 25 hours of operation or
once each year, whichever comes first. Replace more
often if operating under dirty or dusty conditions.
To service the air cleaner, follow these steps:
1. Loosen screws (A) and remove air cleaner cover
(B) (Figure 12).
2. Carefully remove cartridge (C) from base (D).
3. Install clean (or new) air cleaner assembly inside
cover. Dispose of old filter properly.
4. Assemble air cleaner cover onto base and tighten
screws.
Service Spark Plug
Change the spark plug every 100 hours of operation
or once each year, whichever comes first. This will
help your engine to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Check electrode gap with wire feeler gauge and
reset spark plug gap to recommended gap if
necessary (see Figure 13 and Specifications).
4. Replace spark plug if electrodes are pitted,
burned or porcelain is cracked. Use the
recommended replacement spark plug. See
Specifications.
5. Install spark plug and tighten firmly.
Clean Spark Arrester Screen
The engine exhaust muffler has a spark arrester
screen. Inspect and clean the screen every 100 hours
of operation or once each year, whichever comes first.
If you use your generator on any forest-covered,
brush-covered, or grass-covered unimproved land, it
must have a spark arrester. The spark arrester must
be maintained in good condition by the
owner/operator.
