3.13 OUT OF SERVICE PROCEDURE

◆3.13.1 REMOVAL FROM SERVICE

If you cannot exercise the generator every seven days, and it is to be out of service longer than 30 days, pre- pare 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 completely. 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 classification 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 recommend- ed oil is used in the engine (see Section 1.5.4, Page 6). 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 BAT- TERY. 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 neces- sary 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.Your generator is now ready for service.
