MAINTENANCE
DANGER
Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.
Ethylene glycol base antifreeze is poisonous.
Do not use your mouth to siphon coolant from
the radiator, recovery bottle or any container.
Wash your hands thoroughly after handling.
Never store used antifreeze in an open contain­
er because animals are attracted to the smell
and taste of antifreeze even though it is poiso­
nous to them.
---------- Ék CAUTION ià-------------------------
A Do not use any chromate base rust inhibitor with
ethylene glycol base antifreeze, or chromium
hydroxide ("green slime") will form and cause
overheating. Engines that have been operated
with a chromate base rust inhibitor must be
chemically cleaned before adding ethylene glycol
base antifreeze. Using any high silicate antifreeze
boosters or additives also will cause overheating.
We also recommend that you DO NOT use any
soluble oil inhibitor for this equipment.
3.9 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.
3.10 DRIVE BELT
The engine drives the generator rotor by means of
a pulley and drive belt arrangement. Drive belt ten­
sion 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.
3.11 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. If you cannot exercise the generator every
seven days, and it is to be out of service longer than
30 days, see Section 3.12.
3.12 OUT OF SERVICE PROCEDURE
♦ 5.12.1 REMOVAL FROM SERVICE_______________
Prepare the generator for storage as follows:
1. Start the engine and let it run until it is thor­
oughly warmed up (at least five minutes), then
shut off the engine.
2. While the engine is still warm from running,
drain the oil completely. Refill the crankcase with
the recommended oil (see Section 1.5.3, Page 6).
3. Attach a tag to the engine indicating the viscosity
and classification of the oil in the crankcase.
4. 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.
5. Clean and wipe the entire generator.
♦ 3.12.2 RETURN TO SERVICE____________________

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 1.5.3,
Page 6). If necessary, drain and refill with the
proper oil.
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.
Clean and wipe the entire generator.
Reconnect the battery. Observe battery polarity.
Damage may occur if the battery is connected
incorrectly.
Turn OFF all electrical loads. Add fuel if neces­
sary and then start the engine.
Allow the unit to warm up thoroughly.
Apply electrical loads to at least 50 percent of the
unit’s rated wattage capacity.
When the engine is thoroughly warmed up, shut
it down.
Your generator is now ready for service.
