DANGER: Battery electrolyte fluid is an extremely
caustic sulfuric acid solution that can cause
severe bums. Do not permit fluid to contact eyes,
skin, clothing, painted surfaces, etc. Wear protec­
tive goggles, protective clothing and gloves when
handling a battery. If you spill the fluid, flush the
affected are immediately with dear water.
DANGER: Do not use any jumper cables or
booster battery to crank and start the generator
engine. If any battery has discharged, remove It
for recharging.
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 MODEL NUMBER and SERIES.
DRIVE BELTS
The engine drives the generator rotor by means of a pulley
and drive belt arrangement. The drive belt and pulleys are war­
ranted for the life of the generator. Drive belt tension was
properly adjusted before the unit was shipped from the fac­
tory. If you suspect that drive belt tension is incorrect, contact
an authorized 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.
• Close the fuel shutoff valve in the fuel supply line and let
the engine “run out of fuel.”
• While the engine is still warm from running, drain the oil com­
pletely. Refill crankcase with SAE 10W30 oil having API
classification “For Service SF.”
• Attach a tag to the engine indicating the viscosity and clas­
sification of the oil in the crankcase.
• Remove spark plug and pour about two or three table­
spoons of clean, fresh engine oil into spark plug threaded
opening. Crank engine several times to distribute oil, then
install and tighten spark plug.
• Remove the battery and store in a cool, dry room on a
wooden board. Never store the battery on concrete or earth
floors.
• Clean and wipe the entire generator.
RETURN THE UNIT TO SERVICE
AFTER STORAGE
To return the unit to service after storage, proceed as follows:
• Check tag on engine for oil viscosity and classification.
Verify that the correct recommended oil is used in engine.
If necessary, drain and refill with proper oil.
• Check battery. Fill all cells to the proper level with distilled
water. DO NOT USE TAP WATER IN THE BAHERY.
Recharge battery to 100% state of charge, or, if defective,
replace the battery.
• Turn OFF all electrical loads, add fuel if necessary, then start
the engine.
• Let the engine warm up.
• Apply electrical loads to at least 50% of the unit’s rated
wattage capacity.
• When engine is thoroughly warmed up, shut it down.
THE GENEFWOR IS NOW READY FOR SERVICE.
