7.  Attach a tag to the engine indicating the viscosity and clas-

sification of the oil in the crankcase.

8.  Remove the spark plug and spray fogging agent into the spark 

plug threaded openings. Reinstall and tighten the spark plug.

9.  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.

10.  Clean and wipe the entire generator. Use only mild soap and 

water to clean the composite enclosure.

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 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 the engine 

(see the Engine Oil Recommendations section). If necessary, 

drain and refill with the proper oil.

3.  Check the state of the battery. Fill all cells of unsealed bat-

teries 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. 

See “Specifications,” for type and size.

4.  Clean and wipe the entire generator. Use only mild soap and 

water to clean the composite enclosure.

5.  Make sure the 7.5A fuse is removed from the generator con-

trol panel. Reconnect the battery. Observe battery polarity. 

Damage may occur if the battery is connected incorrectly.

6.  Open the fuel shutoff valve.
7.  Insert the 7.5A fuse into the generator control panel. Start the 

unit by moving the AUTO/OFF/MANUAL switch to MANUAL. 

Allow the unit to warm up thoroughly.

8.  Stop the unit by setting the AUTO/OFF/MANUAL switch to 

OFF.

9.  Turn on the utility power to the transfer switch.
10.  Set the AUTO/OFF/MANUAL switch to AUTO.
11.   The generator is now ready for service.

NOTE:

If the battery was dead or disconnected, the exercise timer, cur-

rent date and time must be reset.

4.11.3 ACCESSORIES
