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 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. 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
engine control is in the “stop” position. This should be your last step
before initial start-up.
A customer supplied 12 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.

WARNING: EQUIPMENT DAMAGE:
All of these units are 12 Volt and they are all negative ground.
Permanent damage will occur if they are connected to a 24 Volt system
or a positive ground system. If you are using the truck batteries to start
these units, you may have to disable the charging system to keep it
from interfering with the vehicle charging system.
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:
