**** CAUTION ****
In the following battery installation procedure, check to be sure
the selector switch remains in the “stop” 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 highest CCA rated battery,
within the correct BCI group, will increase cold weather starting
performance.
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 knowledgeable 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 applica-
tion.
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 engine 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.
1. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery 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 battery reverse the procedure,
disconnect the negative cable first and then the positive
cable.
5. Be sure all connections are tight and coat the terminals and
cable end with dialectic 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 immediately
with water.
* If electrolyte contacts the eyes, flush thoroughly and immedi
ately with water and seek immediate medical attention.
* Spilled electrolyte is to be washed down with an acid neutral
izing 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 refilling 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 electrolyte following the procedure above.
NOTE: Always make sure that a new battery is fully charged
before installing it on a generator set. Failure to do so can cause
damage to the engine control module in the generator set.
All connections must be clean and tight. Check the electrolyte
(fluid) in the battery periodically to be sure it is above the plates.
Never allow the battery to remain in a discharged condition.
CONNECTING THE BATTERY CHARGER &
BLOCKHEATER
A three-stage battery charger is provided standard for all 12 volt
standby systems. The standard charger is a Automatic Battery
Charger & Maintainer. This Charger has three rates of charging.
During the first stage, know as BULK Charging, the charging
current is limited to 2 Amps at a voltage of up to 14.5 volts. The
green LED will blink during this stage. During stage two, know as
ABSORPTION Charging, the charging voltage is held at 14.5
volts and the charging rate gradually reduces the amount of
current (amps) flowing to the battery. The green LED will also
blink during this stage. Stage three is called MAINTENANCE
Charging. During this stage the voltage will drop to 13.3 volts and
the charge rate will drop to as low at .1 amps. This keeps your
batteries in a fully charged condition without over charging them.
During this stage the green LED is constantly lit
** NOTICE **
The trickle charger is not intended to recharge a battery which
has become completely discharged. It is designed to produce
just enough current to maintain a fully charged battery.
The battery tender receptacle is to be powered by a GFCI circuit
and installed in accordance with the United States National
Electric Code. These AC wires can be run in the same conduit as
the other AC leads from the generator. It is suggested that this
circuit be fused for 15 amps, then both the battery charger and
the block heater can be connected to the same circuit. A 120 volt
duplex receptacle is mounted on the generator along side circuit
