Generator Maintenance
The generator 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 system as instructed in this manual.
All adjustments in this section should be made at least
once each season. Follow the requirements in the
“Maintenance Schedule” chart above.
Generator maintenance consists of keeping the unit clean
and dry. Operate the unit in an environment where it will
not be exposed to excessive dust, dirt, moisture or any
corrosive vapors. Cooling air louvers on the enclosure
must not become clogged with snow, leaves, or any other
foreign material.
Check the cleanliness of the unit frequently and clean when
dust, dirt, oil, moisture or other foreign substances are
visible on its exterior surface.
NOTE: Do Not use direct spray from a garden hose to
clean generator.Water can enter the engine and cause
problems. In addition, if water enters the generator through
cooling air slots, some water will be retained in voids and
cracks may develop in 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:
CAUTION! Never insert any object or tool
through the air cooling slots, even if the engine is
not running.
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on
dirt, oil, etc.
• 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 openings on
the generator.These openings must be kept clean and
unobstructed.
