GENERAL MAINTENANCE
RECOMMENDATIONS
The Owner/Operator is responsible for making sure that
all periodic maintenance tasks are completed on a timely
basis; that all discrepancies are corrected; and that the unit
is kept clean and properly stored. Never operate a
damaged or defective generator.

Engine Maintenance

See engine manual for instructions.
CAUTION!
Avoid prolonged or repeated skin
contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed areas
with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.

Generator Maintenance

Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a clean dry
environment where it will not be exposed to excessive
dust, dirt, moisture or any corrosive vapors. Cooling air
slots in the generator must not become clogged with snow,
leaves or any other foreign material.
NOTE: Do Not use a garden hose or pressure washer to
clean generator. Water can enter engine fuel system and
cause problems. In addition, if water enters generator
through cooling air slots, some of the water will be
retained in voids and cracks of the rotor and stator
winding insulation. Water and dirt buildup on the generator
internal windings will eventually decrease the insulation
resistance of these windings.

To Clean the Generator

• Use a damp cloth to wipe exterior surfaces clean.
• Soft, bristle brush may be used to loosen caked on dirt
or oil.
• A vacuum cleaner may be used to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and opening on
generator. These openings must be kept clean and
unobstructed.

STORAGE INSTRUCTIONS

The generator should be started at least once every seven
days and allowed to run at least 30 minutes. If this cannot
be done and you must store the unit for more than
30 days, use the following guidelines to prepare it for
storage.

Generator Storage

• Clean the generator as outlined in "To Clean the
Generator."
• Check that cooling air slots and openings on generator
are open and unobstructed.
CAUTION!
Not place a storage cover over a hot generator. Let
the unit cool for a sufficient time before placing the
cover on the unit.

Engine Storage

See engine owner's manual for instructions.

Other Storage Tips

• Do Not store gasoline from one season to another.
• Replace your gasoline can if it starts to rust. Rust and/or
dirt in a gasoline can cause problems when you use
contaminated fuel with this unit.
• Store in clean and dry area.
