4.3.1 — Clean Spark Arrestor Screen
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen at least once each year (Figure 4-6). If unit is used
regularly, inspect and clean more often.
!
If using the generator on any forest-covered, brush-cov-
ered 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 dam-
aged. DO NOT USE a defective screen. If screen is not dam-
aged, clean it with commercial solvent.
3.
Replace the spark arrestor and secure with the clamp and screw.

4.4 — Valve Clearance
• Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008")
• Exhaust — 0.20 ± 0.02mm (cold) (0.008" ± 0.0008")
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 near-
est service center to have the valve clearance adjusted. This is a very
important step to ensure longest life for the engine.
4.5 — Generator Storage
The generator should be started at least once every 30 days and 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 information
as a guide to prepare it for storage.
*
Allow unit to cool entirely before storage.
