CONNECTIONS
(Fuel,
Exhaust,
etc.)
Operator should periodically make a complete visual
inspection of the unit while running at rated
load.
Some of the things to check for are as follows:
1.
Check fuel and oil lines for possible leakage.
2.
Inspect exhaust lines and mufflers for possible
leakage and cracks.
3. Periodically or daily drain moisture from conden-
sation traps.
4.
Inspect water lines and connections for leaks and
security.
5. Inspect electrical wires for security.
AC
GENERATOR
There are no brushes, brush springs or collector rings
on these generators, therefore they require very little
servicing.
Periodic inspections, to coincide with
engine oil changes, will ensure good performance.
Inspection: Inspect generator and control box for
loose or broken wires and parts. Check diodes and
printed circuit boards for excessive dust, grease or
moisture. Blow these assemblies out periodically with
filtered,
low pressure, compressed air.
CAUTION
Excessive foreign matter on diodes and heat
sinks will cause overheating and possible
failure.
Generator Bearing
Inspect the bearing for evidence of outer case
rotation every 1000 hours while the unit is running.
MAINTENANCE
Refer to Table 5 for Operator Maintenance Schedule.
Governor oil level should be even with bottom of the
oil level plug. When adding oil to the governor, the oil
should just start to flow out of the oil level plug hole.
Do not overfill.
If unit is used for "prime power," replace the bearing
every 10,000 hours ortwo years. If the unit is used for
"standby," replace the bearing every five years.
Deterioration of the bearing grease due to oxidation
makes this replacement necessary.
If generator requires major repair or
servicing,
contact an authoriz-
ed Onan dealer or distributor.
