LUBRICATION
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 use the
proper oil and keep the crankcase properly filled will cause
excessive engine wear and shorten its useful life.
COOLANT
Before starting the engine, check the coolant level in radiator. If it
is low, refill as specified in the engine manufacturer’s mainte-
nance instructions. The radiator should be filled to about 1 inch
below the filler neck. For additional information on engine coolant
requirements see engine manufacturer’s maintenance instruc-
tions.
INSTALLING THE BATTERY
**** CAUTION ****
EQUIPMENT DAMAGE - In the following battery installation
procedure, check to be sure the selector switch remains in the
“stop” position.
A customer supplied twelve-volt BCI group 24 battery rated 650
CCA (minimum) is required to complete the installation. Install
the highest CCA rated battery available for best cold weather
starting performance.
****WARNING*****
EQUIPMENT DAMAGE - Always connect the positive battery
cable first and the negative cable last. When disconnecting a
battery always disconnect the negative cable first and the
positive cable last. Failure to follow these steps can cause
arcing at the battery post which can cause damage to both the
engine and the engine control module.
Observe polarities: Connect the positive (+) battery terminal to
the (+) cable from the control panel; the negative (-) battery
terminal is connected to the negative cable (ground) from the
engine generator assembly.
NOTE: Alway 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.
Below is a table of the fuel pressure readings at each reference in
the system.

Notice the preceding tables give two (2) different units of
measuring fuel pressure. The first is with a pressure gauge
calibrated in ounces per square inch. The second and most
accurate is the use of a simple water manometer. A manometer
is calibrated in inches of water column.
LP LIQUID WITHDRAWAL SYSTEMS
When installing a unit equipped the LP liquid withdrawal a
primary regulator is not required on the supply tank. The supply
line is connected to a liquid withdrawal valve on the supply tank
and run directly to the fuellock strainer mounted on the engine
generator set. Normally a 3/8 inch copper line is acceptable for
this type of fuel installation. You must be sure that the valve you
have connected to on the supply tank is in fact a liquid supply
valve and has a drop tube inside the tank that is pulling fuel from
the bottom of the supply tank. Before starting the unit you must
confirm that you have a good liquid supply at the unit. Engine
generators sets equipped for liquid withdrawal will not run
properly when supplied with high pressure vapor fuel.
