3.13 OUT OF SERVICE PROCEDURE
3.13.1 REMOVAL FROM SERVICE
If the generator cannot be exercised every seven days, and it is to
be out of service longer than 30 days, prepare the generator for
storage as follows:
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line and allow
the unit to shut down.
3. While the engine is still warm from running, drain the oil com-
pletely. Refill the crankcase with SAE 10W-30 oil having API
classification “For Service SF.”
4. Attach a tag to the engine indicating the viscosity and clas-
sification of the oil in the crankcase.
5. Remove the spark plug and pour two or three tablespoons of
clean, fresh engine oil into the spark plug threaded openings.
Reinstall and tighten the spark plug.
6. Remove the battery and store it in a cool, dry room on a
wooden board. Never store the battery on any concrete or
earthen floor.
7. Clean and wipe the entire generator.
3.13.2 RETURN TO SERVICE
To return the unit to service after storage, proceed as follows:
1. Check the tag on the engine for oil viscosity and classification.
Verify that the correct recommended oil is used in the engine
(see the "Engine Oil Requirements" section). If necessary,
drain and refill with the proper oil.
2. Check the state of the battery. Fill all cells of unsealed batteries
to the proper level with distilled water. DO NOT USE TAP WATER
IN THE BATTERY. Recharge the battery to 100 percent state of
charge, or, if defective, replace the battery.
3. Clean and wipe the entire generator.
4. Reconnect the battery. Observe battery polarity. Damage may
occur if the battery is connected incorrectly.
5. Turn OFF all electrical loads. Add fuel if necessary and then
start the engine.
6. Allow the unit to warm up thoroughly.
7. Apply electrical loads to at least 50 percent of the unit’s rated
wattage capacity.
8. When the engine is thoroughly warmed up, shut it down.
9. The generator is now ready for service.
