Generator Maintenance
The generator’s warranty does not cover items that have
been subjected to operator abuse or negligence. To receive
full value from the warranty, the operator must maintain the
generator as instructed in this manual.
The generator requires the owner to make some adjustments
periodically to correctly maintain it.
Do all of the service and adjustments at least once each
season. Obey the requirements in the Maintenance Schedule
section.
Keep the unit clean. Operate the unit in an environment that
is free of excessive dust, dirt, moisture, or any corrosive
vapors. Do not allow the cooling air inlets and outlets on the
enclosure to become clogged with snow, leaves, or other
foreign material. To prevent generator damage caused by
overheating, keep the enclosure cooling inlets and outlets
clean and unobstructed at all times.
Examine the cleanliness of the unit frequently and clean it
when dust, dirt, oil, moisture, or other foreign substances
appear on its exterior and interior surface. Inspect the air inlet
and outlet openings inside and outside the enclosure tomake
sure that no blockages are in the airflow.
NOTICE: Incorrect treatment of generator can damage it and
shorten its life.
• DO NOT expose generator to excessive moisture, dust,
dirt, or corrosive vapors.
• DO NOT insert any objects through cooling slots.
Clean the Generator
WARNING
Exhaust heat/gases could ignite combustibles causing a fire,

• Keep the area near the generator clean and free of
debris.
NOTICE: DO NOT use direct spray from a garden hose to
clean the generator. Water can enter the engine and the
generator and cause damage.
NOTICE: Periodically inspect the engine exterior for
contamination and potential damage from dirt, leaves,
rodents, spider webs, insects, etc. and remove.
1. Before you clean your generator, you MUST do steps 1–
6 in the Servicing the System section andthen continue
to step 2 in this section.
2. Clean the generatorusing the steps that follow:
a. Wipe the exterior surfaces clean with a damp cloth.
b. Use a soft bristle brush and vacuum cleaner to
loosen and pick up dirt and debris. Use low-pressure
air (not to exceed 25 psi or 175 kPa) to blow away
dirt and debris.
c. Clear any snow, leaves, or debris from the air inlets
and outlets. Keep these openings unobstructed to
prevent generator damage caused by overheating.
3. After you clean your generator, you MUSTdo steps 8–
