UNPACKING

When receiving the unit, be sure to inspect it carefully for
freight loss or damage. Check the nameplate to be sure it
is what you ordered (proper kW, voltage, fuel, etc.). If you
have questions, contact your local authorized dealer. If
you see evidence of loss or damage at the time of deliv­ery, have the driver sign and describe the loss or damage
in the “memo of loss or damage” section on the freight
bill. Then contact the carrier to get instructions on filing a
claim.

When loss or damage is discovered after the equipment
is delivered, but not seen at the time of delivery, it is
referred to as “concealed damage.” Separate any dam­aged material and contact the carrier for proper proce­dures to file a “concealed damage” claim.

FUEL REQUIREMENTS

See your engine operator's manual for complete type and
fuel grade information.

WARNING -NO BIODIESEL

Filling the Fuel Tank

Standard Trailer - The standard trailer is equipped with a
single 45 gallon fuel tank. Use caution when filling the
tank so as not to overflow the tank into the trailer.

WARNING PERSONAL DANGER

Never refuel a running engine. Always stop the engine
and allow to cool before refueling.

Never allow the fuel tank to run completely empty, as air
may enter the fuel system making it necessary to bleed
the engine when restarting.

COOLANT REQUIREMENTS

The cooling system of this engine has been filled at the
factory with a 50% water and 50% ethylene-glycol
antifreeze and the proper amount of supplemental coolant
additives. This mixture provides engine protection to -37
degrees F.

8190-00

When replenishing coolant or changing coolant refer to
your Isuzu engine manual for the proper type and mixture
of water, antifreeze and supplemental coolant additives.

CAUTION – A battery presents a risk of electrical shock and
high short circuit current. The following precautions must be
observed when working with batteries:

WARNING: EQUIPMENT DAMAGE

Failure to properly follow Isuzu requirements for anti­freeze and supplemental coolant additives can lead to
permanent damage to your engine cylinder liner walls.

BATTERY CONNECTION INSTRUCTIONS

WARNING! EQUIPMENT DAMAGE

FAILURE TO PUT THE ENGINE CONTROL SWITCH IN
THE ‘OFF’ POSITION PRIOR TO CONNECTING THE
BATTERY CABLE(S) MAY RESULT IN DAMAGE TO
THE ECM. (SOLID STATE ENGINE CONTROL MOD­ULE).

INSTALLING THE BATTERY

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.

MINIMUM

Model Voltage BCI Group CCA Rating
RP25 12 24 650

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 application.

CAUTION – PERSONAL DANGER

NEVER dispose of 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.

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.

3. 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.

4. 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
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 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..
