Section 8. Periodic Maintenance
Schedule
Regularly scheduled maintenance means lower operat-
ing costs and longer service life for the generator set.
The following schedule may be used as a guide. How-
ever, actual operating conditions should determine the
maintenance schedule. In exceptionally dusty or dirty
conditions, certain service periods may have to be re-
duced. Check the condition of the crankcase oil, filters,
etc., frequently, until the proper service time periods are
established.
If any abnormalities in operation, unusual noises from
engine or accessories, loss of power, overheating, etc.
occur, contact the nearest authorized Onan dealer.
Exhaust gas presents the hazard of se-
vere personal injury or death. Inspect the exhaust
system audibly and visually each day, or each time
the generator is started (whichever is sooner). With
the generator set running, momentarily open the ac-
cess cover to inspect the muffler. Shut down the
generator set and have any leaks repaired immedi-
ately.
Failure to disconnect the generator set
battery could result in damage to equipment or seri-
ous personal injury in the event of inadvertent start-
ing. Before beginning any maintenance work on the
engine, generator, control panel, automatic transfer
switch or associated wiring, disconnect the battery,
negative (-) cable first.
Many troubleshooting and mainte-
nance procedures present hazards which can result
in severe personal injury or death. Only qualified
service personnel with knowledge of fuels, electric-
ity, and machinery hazards should perform service
procedures. Review safety precautions on inside
cover page before attempting these maintenance
procedures.
