3.3.7 SPARK ARRESTOR

The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen at least once each year (Figure 9). 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 as follows:
1. Remove clamp and spark arrestor from 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 clamp.

3.5 VALVE CLEARANCE

• Intake — 0.10 ± 0.02mm (cold), (0.004" ± 0.0008" inches)
• Exhaust — 0.15 ± 0.02mm (cold) (0.006" ± 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.

3.6 GENERAL

be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
