The maximum ambient temperature for your
generator is 48.9° C (120° F).
3.9 DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. The drive train,
drive belt and pulleys are warranted for the life of the
generator. Drive belt tension was properly adjusted
before the unit was shipped from the factory. If you
suspect that drive belt tension is incorrect, contact a
Generac/Guardian Authorized Dealer.
3.10 ATTENTION AFTER SUBIVIERSION
If the generator has been submerged in water,
it
MUST NOT
be started and operated. Following
any submersion in water, have a Generac/
Guardian Authorized Dealer thoroughly clean and
dry the generator.

3. Once the unit has shut down, it will signal a low
oil fault.
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 oil. See "Engine Oil Recommendations,”
section 3.3.1 (page 11).
6. Attach a tag to the engine indicating the viscos­
ity 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, diy
room on a wooden board. Never store the bat­
tery on any concrete or earthen floor.
9. Clean and wipe the entire generator.
♦ 5.11.2 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 recom­
mended oil is used in the engine (see section
3.3.1, page 11). 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 “Specifications,” section 1.7 (page 6),
for type and size.
4. Clean and wipe the entire generator.
5. Reconnect the battery. Observe battery polarity.
Damage may occur if the battery is connected
incorrectly.
