Section 4: Maintenance

Corrosion Protection

Regular scheduled maintenance should be conducted to
perform a visual inspection of the unit for corrosion.
Inspect all metal components of the generator. Example:
Base frame, enclosure, brackets, alternator can, the
entire fuel system (inside and outside of the generator)
and fastener locations. If there is corrosion found on
generator components (i.e. regulator, engine/alternator
mounts, fuel plenum, etc.), replace parts as necessary.
Periodically wash and wax the enclosure using
automotive type products. Do not spray the unit with a
hose or power washer. Use warm, soapy water and a soft
cloth.Frequent washing is recommended in salt water/
coastal areas. Spray engine linkages with a light oil such
as WD-40.
