a comparable product.
4.12  OUT OF SERVICE PROCEDURE
4.12.1  REMOVAL FROM SERVICE
If the generator cannot be exercised every seven days, 
and will be out of service longer than 90 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.  Once the unit has shut down, it will signal a low 
oil fault.
4.  Set the generator’s main circuit breaker to its 
OFF (or open) position.
5. Set the Auto/Off/Manual switch to OFF and 
turn off the utility power to the transfer switch. 
Remove the 7.5A and 15A fuses from the genera-
tor control panel. Disconnect the battery cables 
as outlined in “General Hazards” (page 2). Turn 
on the utility power supply to the transfer switch 
in order to power the emergency load centers cir-
cuits while utility power is available.
6.  While the engine is still warm from running, 
drain the oil completely. Refill the crankcase with 
oil. See ”Engine Oil Recommendations,” Section.
7.  Attach a tag to the engine indicating the viscosity 
and classification of the oil in the crankcase.
8.  Remove the spark plug(s) and spray fogging 
agent into the spark plug(s) threaded openings. 
Reinstall and tighten the spark plug(s).
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.
4.12.2 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 recom-
mended oil is used in the engine (see “Engine Oil 
Recommendations”). If necessary, drain and refill 
with the proper oil.
3.  Check the state of the battery. Fill all cells of 
unsealed batteries to the proper level with dis-
tilled water. DO NOT USE TAP WATER IN THE 
BATTERY. Recharge the battery to 100 percent 
state of charge, or, if defective, replace the bat-
tery. See the “Specifications” Section, for type and 
size.
4.  Clean and wipe the entire generator.
5.  Remove the 7.5A and 15A fuses from the genera-
tor control 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 and 15A fuses 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 exer-
cise timer must be reset.
