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 once a year (Figure 19). Clean or replace more often if operating under dusty conditions. Clean foam pre-cleaner every month or more often under dusty conditions.

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 as follows:

• Remove the screen retaining bracket by removing the screw.
