Generator Service
General
Under normal conditions generator service will not be
requiredonaregularbasis.Ifoperatingunderextremely
dusty and dirty conditions, use DRY compressed air to
blow out the generator at frequent intervals. Do this with
the generator set operating and direct the stream of air
in through the cooling slots at the end of the generator.
Because of the generator set design, brush service
should be practically nonexistent. The brushes operate
at a very low amperage and should last indefinitely.
Abrasive dust on the slip rings could, however shorten
the life of the brushes. If brush replacement becomes
necessary due to poor or no AC output, contact an
Authorized Service Dealer to have this done.
The end bracket bearing should be replaced every
10,000 hours of operation. Service more frequently if
bearing inspection indicates excessive rotor end play or
bearing damage from corrosion or heat build-up. The
endbracketbearingissealedandrequires noadditional
lubrication. All generator service must be performed by
an authorized service dealer.
Storage Procedure
1. Drain the oil (while hot) from the crankcase, then
refill with regular grade oil. See Section 3, “Oil
Selection” in this manual.
2. Drain the fuel from the fuel tank to prevent
accumulated moisture from mixing with the fuel.
3. Check the engine coolant level and specific
gravity. See Section 3, “Cooling System” for
additional information.
4. Disconnect battery (negative lead first) and place
in storage.
5. Seal all openings in the engine with
non-absorbent adhesive tape. Mask off all areas
to be used for electrical contact.
6. Clean exterior surface of the generator. Spread a
light film of oil over unpainted metallic surfaces
which could rust or corrode.
