BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in use.
The generator battery should be inspected per the
“Service Schedule,” Section 3.13 (Page 16). The fol
lowing procedure should be used for inspection:
• Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
• Have the state of charge and condition checked by
a Generac authorized Service Dealer.
NOTE:
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batter
ies and the required precautions. Keep unautho
rized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.
DANGER
-A
WARNING A-
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batter
ies give off explosive hydrogen gas. This gas
can form an explosive mixture around the bat
tery 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 ventilated. Do not allow smoking,
open flame, sparks, or any spark producing
tools or equipment near the battery. Discharge
static electricity from your body before touch
ing the battery by first touching a grounded
metal surface.
A battery presents a risk of electrical shock
and high short circuit current. The following
precautions are to be observed when working
on batteries:
• 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.
A
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.
• 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) of 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.
3.7
COOLING SYSTEM
Air intake and outlet openings in the generator com
partment must be open and unobstructed for contin
ued proper operation. This includes such obstructions
as high grass, weeds, brush, leaves and snow.
Without sufficient cooUng and ventilating air flow, the
engine/generator quickly overheats, which causes it to
shut down.
3.8
ENGINE COOLANT
Check the coolant level in the coolant recovery tank at
least once daily or prior to use. Add the recommended
coolant mixture (see Section 1.5.4, Page 6) as neces
sary; the bottle should be kept half full. If desired, you
may add a high quality rust inhibitor to the recom
mended 50-50 coolant mixture. If added consistently,
the recommended mixture will protect the unit against
freezing temperatures.
Periodically remove the radiator pressure cap to
make sure the coolant recovery system is functioning
properly. Coolant should be at the bottom of the radi
ator filler neck. If the coolant level is low. Inspect the
gasket in the radiator pressure cap. Replace the cap,
if necessary. To have the pressure cap tested, contact
a Generac Authorized Service Deader. Inspect the
cooling system and coolant recovery system for leaks.
