NOTE:
3.5.1 CLEAN SPARK ARRESTOR SCREEN (CARB
MODELS)
The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen at least once each year (Figure 17). 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:
1. Remove the spark arrestor screen from the muffler by
loosening the clamp and removing the screw.
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 secure with the clamp and
screw.

3.6 VALVE CLEARANCE

• Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008" inches)
• Exhaust — 0.20 ± 0.02mm (cold) (0.008" ± 0.0008" inches)
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to ensure longest life for the engine.
