INSTALLING THE BATTERY
**** CAUTION ****
In the following battery installation procedure, check
to be sure the selector switch remains in the “off”
position. This should be your last step before initial
start-up.
A customer supplied twelve-volt battery is required to
complete the installation. Installation of the high-
est CCA rated battery, within the correct BCI group
(size), will increase cold weather starting perfor-
mance. Gel batteries should not be used with the
battery tender installed in the generator enclosure.

Installation and servicing of batteries must be
performed or supervised only by personnel knowl-
edgeable of batteries and the required precautions.
Keep unauthorized personnel away from batteries.
When installing or replacing batteries, use the proper
group/size starting battery. The battery should be
a Maintenance Free lead acid design. Deep cycle
batteries will not work for this application.
CAUTION - PERSONAL DANGER
CAUTION - NEVER dispose of a battery in a fire.
The battery is capable of exploding.
CAUTION - DO NOT open or mutilate the battery.
Released electrolyte is known to be harmful to the
skin and eyes and to be very toxic.
These generator sets are all NEGATIVE ground. Be
very careful not to connect the battery in reverse
polarity, as this may short circuit the battery charging
system on the engine.
CAUTION - A battery presents a risk of electrical
shock and high short circuit current. The following
precautions must be observed when working with
batteries.
. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the bat-
tery posts to be sure they are free of corrosion.
4. Always connect the battery positive cable first
and then connect the battery negative cable.
When removing the battery cables from the bat-
tery, reverse the procedure and disconnect the
negative cable first and then the positive cable.
5. Be sure all connections are tight and coat the
terminals and cable ends with dielectric grease.
WARNING - The electrolyte is a diluted sulfuric acid
that is harmful to the skin and eyes. It is electrically
conductive and corrosive. The following precautions
must always be taken.
* Always wear full eye protection and protective
clothing.
* Where electrolyte contacts the skin, wash off im-
mediately with water.
* If electrolyte contacts the eyes, flush thoroughly
and immediately with water and seek immediate
medical attention.
* Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of one pound of bicarbonate of
soda (baking soda) to one gallon of water. The
bicarbonate 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.
DANGER - Explosive Fire Risk
* Never smoke when near batteries.
* Do not cause a flame or spark in the battery area.
* Always discharge static electricity from your body
before touching batteries by first touching a
grounded metal surface.
SERVICING BATTERIES
Batteries used on these units may over time lose
water. This is especially true if you are using a
trickle charger to maintain your battery. When refill-
ing the battery with water, use only distilled water.
Tap water will shorten the service life of the battery.
Never fill the battery above the fill line. Over filling
above the upper level line may cause the electrolyte
to overflow, resulting in corrosion to the engine or
nearby parts. Immediately wash off any spilled elec-
trolyte following the procedure above.
BATTERY CHARGING
Units equipped with electric start have a small fly-
wheel charger built into the engine flywheel assem-
bly for recharging the starting battery. This flywheel
charger generates a small AC current that passes
through a rectifier/regulator assembly on the engine
to produce a DC charging current. This circuit is not
designed to be used as a battery charging circuit to
recharge dead batteries.
