4.11 OUT OF SERVICE PROCEDURE

‹4.11.1 REMOVAL FROM SERVICE

If the generator cannot exercise every seven days, and it is to be out of service longer than 90 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.Once the unit has shut down, it will signal a fault on the control panel.

4.Set the Auto/Off/Manual switch to OFF and turn off the utility power to the transfer switch.

5.While the engine is still warm from running, drain the oil completely. Refill the crankcase with SAE 15W-40 oil having API Service Class SG, SH or SJ.

6.Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase.

7.Remove the spark plug(s) and spray fogging agent into the spark plug(s) threaded openings. Reinstall and tighten the spark plug(s).

8.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.

9.Clean and wipe the entire generator.

‹4.11.2 RETURN TO SERVICE

To return the unit to service after storage, proceed as follows:

1.Verify that utility power is turned off to the transfer switch and that the Auto/Off/Manual switch is set to OFF.

2.Check the tag on the engine for oil viscosity and classification. Verify that the correct recommended oil is used in engine, see Section 4.2.1. If necessary, drain and refill with the proper oil.

3.Check the battery. Fill all cells to the proper level with distilled water. DO NOT USE TAP WATER IN THE BATTERY. Remove the battery before charging. Recharge the battery to 100 percent state of charge, or, if defective, replace the battery with a 12-volt DC Group 27F battery rated for 90 amp hours (part # 058665).

4.Clean and wipe the entire generator.

5.Reconnect the battery. Observe battery polarity. Damage may occur if the battery is connected incor- rectly.

6.Open the fuel shutoff valve.

7.Start the unit by moving the Auto/Off/Manual switch to MANUAL. Allow the unit to warm up thoroughly.

8.Stop the unit and set the Auto/Off/Manual switch to AUTO.
