3.4 SERVICE AIR CLEANER
The engine will not run properly and may be damaged if using a
dirty air cleaner. Clean or replace the air cleaner paper filter every
200 hours or once a year (Figure 13). Clean or replace more often
if operating under dusty conditions.
To clean or replace paper air filter:
• Remove air cleaner cover; then remove the paper filter.
• Clean paper filter by tapping it gently on a solid surface. If the
filter is too dirty, replace it with a new one. Dispose of the old
filter properly.
• Clean air cleaner cover, then insert new paper filter into the base
of the air cleaner. Re-install air cleaner cover.

NOTE:
3.5 CLEAN SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen every 100 hours or at least once each year (Figure
14). If unit is used regularly, inspect and clean more often.
If using the generator on any forest-covered,
brush-covered or grass-covered unimproved
land, it must equipped with a spark arrestor.
The spark arrestor must be maintained in good
condition by the owner/operator.
Clean and inspect the spark arrestor when the engine is at ambient
temperature as follows:
• Insert a flat blade screwdriver through the slot on the side of
the muffler heat shield to access the spark arrestor clamp.
Loosen the clamp and remove the spark arrestor screen from
the muffler.
• Inspect screen and replace if torn, perforated or otherwise
damaged. DO NOT USE a defective screen. If screen is not
damaged, clean it with commercial solvent.
• Replace the spark arrestor and tighten the clamp.
