COOLANT
WARNING: PERSONAL INJURY:
Never open a hot radiator cap.
Before starting the engine, check the coolant level in the radiator
overflow. If it is low, refill as needed. For additional information on
engine coolant requirements, see engine manufacturer’s maintenance
instructions.
INSTALLING THE BATTERY
CAUTION:
In the following battery installation procedure, check to be sure the
DSE7310 is in the “stop” position. This should be your last step before
initial start-up.
A customer supplied Group 24/350 CCA 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.

Installation and servicing of batteries must only be preformed or
supervised 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 application.
CAUTION: PERSONAL DANGER:
NEVER
dispose a battery in a fire. The battery is capable of exploding.
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
first and then the positive cable.
5. Be sure all connections are tight and coat the terminals and cable
ends with dialectic grease.
WARNING:
The electrolyte is diluted sulfuric acid that is harmful to the skin
and eyes. It is electrically conductive and corrosive. The following
precautions must always be taken.
1. Always wear full eye protection and protective clothing.
2. Where electrolyte contacts skin, wash off immediately with water.
3. If electrolyte contacts the eyes, flush thoroughly and immediately
with water and seek immediate medical attention
4. 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:
1. Never smoke when near batteries.
2. Do not cause a flame or spark in the battery area.
3. Always discharge static electricity from your body before touching
batteries by first touching a ground 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. Different types of batteries require various types
of maintenance. Refer to the battery manufacturer for specific
recommendations.
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. Depending on your battery
type, check the electrolyte in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a discharged
condition.
CONNECTING BATTERY CHARGER & BLOCKHEATER
A three-stage battery charger is provided standard on this unit. The
charger is an Automatic Battery Charger & Maintainer. This charger
has three rates of charging. During the first mode, known as Bulk
charging, the charging current is limited to 10 Amps at a voltage of up
to 14 Volts. The yellow LED will be on constantly during this stage.
When the charging rate drops to 2.5 Amps, the charge will enter the
ABSORPTION charging mode. During this mode, the yellow LED will
be flashing. The charging voltage is held at 14 Volts and the charging
rate gradually reduces the amount of current (Amps) flowing to the
battery to 100% charged state. The battery can be left on this mode
indefinitely. During this mode, the green LED will be on constantly.
This charger is mounted under the customer connection on the control
side of the generator and plugged into the receptacle mounted in
the AC connection cabinet. The battery charger receptacle is to be
powered by a GFCI circuit and installed in accordance to the US
National Electric Code. It is suggested that this circuit be fused to 20
Amps.
