Onan CCKB User Manual

DUST AND DIRT
Keep set clean. Keep cooling system clean.
2. Service air cleaner as frequently as necessary.
3. Change crankcase oil every 100 operating hours.
4. Keep oil and gasoline in dust-tight containers.
5. Keep governor linkage clean.
6. Clean generator brushes, slip rings and com¬
mutator — do not remove normal (dark brown)
film. Do not polish.
EXTENDED OUT-OF-SERVICE PROTEC¬
TION
Generator sets removed from service for extended
periods of time (over 30 days) should be protected
from rust and corrosion. Onan recommends the
following protective procedure:
1. Run set until thoroughly warm with generator
under at least 50 percent load. Stop engine by
shutting off fuel supply to allow engine to drain
fuel lines and carburetor.
2. Drain oil base while still warm. Refill and attach a
tag indicating viscosity of oil used.
3. Remove spark plugs. Pour 1-ounce of rust in¬
hibiting oil (or SAE #10 oil) into each cylinder.
Crank engine over several times, install spark
plugs.
4. Service air cleaner.
5. Clean throttle and governor linkage; protect by
wrapping with a clean cloth.
6. Plug exhaust outlets to prevent entrance of
moisture, bugs, dirt, etc.
7. Clean off dirt and dry entire unit. Coat parts likely
to rust with a light film of oil or grease.
8. Disconnect battery and follow standard battery
storage procedure. Apply a film of non-
conductive grease (e.g., vaseline) to battery cable
terminal lugs.
9. Fill fuel tank to prevent condensate contamina¬
tion.
10. P r ovide a suitable protective cover for the entire
unit.
WARNING If smoke while servicing batteries.
Explosive gases are emitted from
batteries in operation. Ignition of these gases can cause
severe personal injury.
4. Connect batteries.
5. Verify that no loads are connected to the
generator.
6. Start engine.
After engine has started, excessive blue smoke will be
exhausted and the engine wili run rough untii the rust inhibitor
or oil has burned away.
7. After start, apply load to at least 50 percent of
rated capacity.
8 Check all gauges for correct reading. Unit is
ready for service.
RETURNING UNIT TO SERVICE
1. Remove cover and all protective wrapping.
Remove plug from exhaust outlet.
2. Check tag on oil base and verify that oil viscosity
is still correct for existing ambient temperature.
3. Clean and check battery. Measure specific gravity
(1.260 at 25° C [77° F] ) and verify level to be at
split ring. If specific gravity Is low, charge until
correct value is obtained. If level Is low, add
distilled water and charge until specific gravity is
correct. DO NOT OVERCHARGE.
