Onan CCK Series Operator's Manual And Parts Catalog

OPERATION
BEFORE STARTING
Be sure the crankcase has been filled with oil to the
"FULL” mark on the oil level indicator. Refer to the
Maintenance Section for the recommended oil changes
and complete lubricating oil recommendations.
ELECTRIC STARTING
Push the START-STOP switch to its "START” posi¬
tion. Release the switch as soon as the engine starts.
If the engine fails to start at first try, inhibitor oil
used at the factory may have fouled the spark plug.
Remove the plug, clean in a suitable solvent, dry
thoroughly and install. Heavy exhaust smoke when
the engine is first started is normal and is caused
by the inhibitor oil.
If the battery charge condition is too low to crank
the engine, the plant can be started manually. Set
the control box switch (located inside the control
box) to its manusl start position. Pull the rope with
a fast, steady pull to crank the engine. Do not jerk.
After starting, return the control box switch to the
electric start position to avoid discharging the battery.
APPLYING LOAD
If practical, allow plant to warm up before connecting
a heavy load. Continuous generator overloading may
cause high operating temperatures that can damage
the wlDdings. Keep the load within nameplate rating.
STOPPING
1. Push start-stop switch to stop position.
2. Release switch when plant stops. If stop circuit
fails, close fuel valve.
BREAK-IN PROCEDURE
Controlled break-in with the proper oil and a con¬
scientiously applied maintenance program will help
to assure satisfactory service from your Onan electric
plant.
When operating engine for the first time, use the
following sequence using MS/DG oil:
1. One half hour at 1/2 load.
2. One half hour at 3/4 load.
3. Full load.
4. Change crankcase oil after the first 50 hours of
operation.
BATTERY CHARGING
The battery charge rate is automatically controlled
by a voltage regulator. The high charge rate was set
at the factory for average operating conditions. If
frequent starts and short operating periods require
an increased charge rate, adjust by moving the slide
clip on the adjustable resistor in the control box. Do
not exceed Samps.
INFREQUENT SERVICE
If the plant is used infrequently, extended shutdown
periods can result in difficult starting. Run the plant
at least 30 minutes every week to eliminate hard
starting.
HIGH TEMPERATURES
1. See that nothing obstructs air flow to and from
the plant.
2. Keep cooling fins clean. Air housing should be
properly installed and undamaged.
3. Kee|^ ignition timing properly adjusted.
LOW TEMPERATURES
1. Use correct SAE No. oil for temperature conditions.
Change oil only when engine is warm. If an
unexpected temperature drop causes an emergency,
move the plant to a warm location or apply heat
externally.
2. Use fresh, standard grade gasoline. Protect
against moisture condensation. Below 0°F adjust
carburetor main jet for slightly richer fuel mixture.
3. Keep ignition system clean, properly adjusted and
batteries in a well charged condition.
4. Partially restrict cool air flow, but use care to
avoid overheating.
OUT-OF-SERVICE PROTECTION
Protect a plant that is to be out-of-service (or more
than 30 days as follows:
1. Run the plant until thoroughly warm.
2. Turn off fuel supply and run until plant stops.
3. Drain oil from oil base while still warm. Refill
and attach a warning tag stating oil viscosity used.
4. Remove each spark plug. Pour loz. (two table¬
spoons) of rust inhibitor (or SAE #50 oil) into
each cylinder. Crank engine slowly (byi-hand)
several times. Install spark plugs.
5. Service air cleaner.
6. Clean governor linkage and protect by wrapping
with a clean cloth.
7. Plug exhaust outlet to prevent entrance of moisture,
dirt, bugs, etc.
8. Wipe generator brushes, slip rings, etc. Do not
apply lubricant or preservative.
9. Wipe entire unit. Coat rustable parts with a light
film of grease or oil.
10. I f battery is used, disconnect and follow standard
battery storage procedure.
