3.10 MAJOR SERVICE MANUAL
To obtain a service manual for your generator, con-
tact Generac or your nearest Generac Authorized
Service Dealer. Make sure to identify your MODEL
NUMBER and SERIES.
3.11 DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. The 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
Authorized Service Dealer.
3.12 EXERCISING THE GENERATOR
Generac recommends that you start and operate the
generator at least once every seven days. Let
the unit run for at least 30 minutes to “exercise”
the engine.
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.
