schedwfe of inspection and ser-
fig hours (Table 1). Keep an
accurate\ logbook Qf^ maintenance, servicing, and
operatingMmie Use the running time meter (optional
equipment)TEr1<eep a record of operation and ser-
vicing. Regular service periods are recommended for
normal service and operating conditions. For con-
tinuous duty, extreme temperature, etc., service more
frequently. For infrequent use, lightduty, etc., service
periods can be lengthened accordingly. Refer to
Figure 17 for engine maintenance information.
W A R N I N G
Before commencing any maintenance work
on the engine, generator, control panel,
transfer switch or associated wiring, disconnect
automatic
batteries. Failure to do so could result in damage to the unit or
serious personal injury in the event of inadvertent starting.
Operator should periodically make a complete visual
inspection with set running at rated load. Some of the
things to check for are as follows:
1. Check all fuel and oil lines for possible leakage.
2. Inspect exhaust lines and mufflers for possible
leakage and cracks.
3. Periodically ordaily, drain moisture from conden-
sation traps.
4. Inspect air shrouds for leaks and security. Besure
cooling fins are clean.
5. Inspect electrical wires and connections for
security and fray damage.
If generator requires major repair or servicing, contact an authoriz-
ed Onan dealer or distributor.
AC GENERATOR
Periodic inspections that coincide with engine oil
changes will ensure good performance.
BEGIN SPEC AA.
When inspecting the rotating rectifier assembly,
make sure diodes are free of dust, dirt and grease.
Excessive foreign matter on these diodes and heat
sinks will cause the diodes to overheat and will result
in their failure. Blow out the assembly periodically,
with filtered, low pressure air. Also check to see that
diodes and leadwires are properly torqued. The
diodes should be torqued to 25 in. Ib. or finger tight
plus a quarter turn. See Figure 1.
BATTERIES
Check the condition of the starting batteries at least
every two weeks. See that connections are clean and
tight. A light coating of non-conductive grease will
retard corrosion at terminals. Keep the electrolyte at
the proper level above the plates by adding distilled
water. Check specific g ravity; recharge if below 1.280.
MAINTENANCE S C H E D U L E
Use this factory recommended maintenance
schedule (based on favorable operating conditions)
to serve as a guide to get long and efficient set life.
Neglecting routine maintenance can result in failure
or permanent damage to the set.

NOTE 1. Water or foreign material in fuel can ruin the injection
system. If daily inspection shows water or excessive dirt
in sediment bowl fuel, handling and storing facilities
should be checked and situation corrected. Primary and
secondary fuel filters must be replaced following correc-
tion of fuel contamination problem.
2. This service must be conducted by trained diesel
injection equipment personnel with suitable test
facilities. Omit this service until these conditions can be
met.
3. Tighten head bolts and adjust valve clearance after first
50 hours on an overhauled engine.
OIL FILTER CHANGE
Place pan under old filter and remove by screwing
counterclockwise. Clean filter mounting area. Install
new filter, oil filter gasket and screw filter on
clockwise until gasket touches mounting base, then
tighten 1/2 turn.
