GENERATOR MAINTENANCE
Generator maintenance constists of keeping the unit clean
and dry. Operate and store the unit in a clean dry environ-
ment 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.
Check the cleanliness of the generator frequently and clean
when dust, dirt, oil, moisture or other foreign substances
are visible on its exterior surface
NOTE: We DO NOT recommend using a garden hose to
clean generator_ Water can enter the engine fuel system
and cause problems In additon, if water enters the gener-
ator 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:
o 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.
o Low pressure air (not to exceed 25 psi) may be used
to blow away dirt. Inspect cooling air slots and open-
ings on the generator_ These openings must be kept
clean and unobstructed.
CAUTION: Never insert any object or tool through
the air cooling slots, even if the engine Is not
running. Damage to the unit or personal injury may
result.
Change oil after first 8 hours of operation. Change oil every
50 hours thereafter. If you are using your generator under
dirty or dusty conditions, or in extremely hot weather,
change oil more often,
Change oil while engine is still warm from running, as
follows:
I_ CAUTION: Disconnect spark plug wire from spark ]
