DANGER
Do not dispose of the battery in a fire. The bat-
tery is capable of exploding. Storage batteries
give off explosive hydrogen gas. This gas can
form an explosive mixture around the battery
for several hours after charging. The slightest
spark can ignite the gas and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other injury. Any area that
houses a storage battery must be properly venti-
lated. Do not allow smoking, open flame, sparks,
or any spark producing tools or equipment near
the battery. Discharge static electricity from body
before touching the battery by first touching a
grounded metal surface.
A battery presents a risk of electrical shock and
high short circuit current. The following precau-
tions are to be observed when working on bat-
teries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connecting
or disconnecting battery terminals; and
• 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.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush
thoroughly and immediately with water and seek
medical attention; and
• Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or water. The bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.
3.10 MAJOR SERVICE MANUAL
To obtain a service manual for the generator, con-
tact the nearest Authorized Service Dealer or, go to
www.generac.com. Make sure to identify the 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 suspecting that the drive
belt tension is incorrect, contact an Authorized Service
Dealer.
3.12 EXERCISING THE GENERATOR
The manufacturer recommends starting and operat-
ing 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 the generator cannot be exercised 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.
