MAJOR SERVICE MANUAL
To obtain a service manual for your generator, order it from
your dealer/distributor or contact the factory. Be sure to iden
tify
your unit’s MODEL NUMBER and SERIAL NUMBER.
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 form the fac
tory. If you suspect that drive belt tension is incorrect, contact
an autorized service facility.
EXERCISING THE GENERATOR
Generac recommends that you start and operate the gener
ator at least once every seven days. Let the unit run for at
least 30 minutes to “exercise” the engine.
OUT OF SERVICE PROTEQION
If you cannot exercise the generator every seven days and it
is to be out of service longer than 30 days, prepare the gen
erator for storage as follows;
• Start the engine and let it warm up.
• While the engine is still warm from running, drain the oil com
pletely. Refill crankcase with recommended oil. See
“Specifications.”
• Attach a tag to the engine indicating the viscosity and clas
sification of the oil in the crankcase.
• Remove spark plugs and add about 1/2 ounce (15ml) of
clean, fresh engine oil into spark plug threaded openings.
Crank engine several times to distribute oil, then install and
tighten spark plugs.
• Remove the battery and store in a cool, dry room on a
wooden board. Never store the battery on any concrete or
earthen floor.
• Clean and wipe the entire generator.
