3.6 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 15). 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 be 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:
1. 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.
2. 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.
3. Replace the spark arrestor and tighten the clamp.
