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 highest CCA rated battery,
within the
correct BCI group (size), 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 persons knowledgeable of batteries
and the required precautions. Keep unauthorized persons
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 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
and damage electronic components.
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
and disconnect the negative cable first and then the
positive cable.
LUBRICATION & COOLANT
Before starting the engine, check the oil level in the
crankcase. If it is low, refill to the full mark with the proper
weight/grade of oil as recommended by the engine
manufacturer’s maintenance instructions. The necessity of
using the correct oil and keeping the crankcase full cannot
be over emphasized. Failure to do so will cause excessive
engine wear and shorten its useful life.
Before starting the engine, Check the coolant level in
the radiator. If it is low, refill as specified in the engine
manufacturer’s maintenance instructions. The radiator
should be filled to about 1 inch below the filler neck.

NG/LP FUEL CONVERSION
This generator set was tested on both LP and NG at the
factory. Ensure proper fuel configuration before operating.
CAUTION: EQUIPMENT DAMAGE
Do not make any fuel adjustments or governor adjustments
until all pressure readings are in compliance with
specification.
These engine/generator sets are easy to convert between
LP or NG. As the engine timing is controlled by the ECU on
the engine you only need to tell it what fuel you want to
operate on. A small rocker switch has been provide on the
underside of the engine control cabinet for this purpose.
Opening the rocker switch will tell the ECU mounted on
the engine that you are operating on NG Fuel. Closing the
rocker switch will tell the ECU that the fuel being supplied is
LP. The Advance Power Controller has an indicator light for
LP. When this light is on, the engine is set-up for LP, when
the LP light is out the engine is set up for NG. The ECU will
then reprogram the engine to operate on the proper fuel.
