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.
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.
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.
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.

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.
