Battery short circuits. Explosion can cause severe injury
or death. Short circuits can cause bodily injury and/or
equipment damage. Disconnect the battery before generator
set installation or maintenance. Remove all jewelry before
servicing the equipment. Use tools with insulated handles.
Remove the negative (--) lead first when disconnecting the
battery. Reconnect the negative (--) lead last when
reconnecting the battery. Never connect the negative (--)
battery cable to the positive (+) connection terminal of the
starter solenoid. Do not test the battery condition by shorting
the terminals together.
Use a 12-volt battery with a minimum rating of 675 cold
cranking amps at --18_C (0_F) The generator set uses a
negative ground with a 12-volt engine electrical system.
Make sure that the battery is correctly connected and
the terminals are tight. See Figure 2-9.
Note: The generator set will not start and circuit board
damage may result if the battery is connected in
reverse.

Cleaning the Battery

To prevent dirt and grime buildup, occasionally wipe the
battery with a damp cloth.
To prevent corrosion, maintain tight, dry electrical
connections at the battery terminals.
corrosion from battery terminals, disconnect the cables
from the battery and scrub the terminals with a wire
brush. Clean the battery and cables with a solution of
baking soda and water. Do not allow the cleaning
solution to enter the battery's cells. After cleaning, flush
the battery and cables with clean water and wipe them
with a dry, lint-free cloth.

Battery Charger

Generator sets are equipped with a factory-installed
battery charger to keep the starting battery fully
charged. Observe the battery polarity when connecting
the battery charger. Check the battery charger fuse and
power supply.
See the Generator Set Operation Manual for
information about battery charger operation and
troubleshooting.

2.8 Storage Procedure

Perform the following storage procedure before taking a
generator set out of service for three months or longer.
Follow the engine manufacturer's recommendations, if
available, for fuel system and internal engine
component storage.
2.8.1

Lubricating System

Prepare the engine lubricating system for storage as
follows:
1. Run the generator set for a minimum of 30 minutes
to bring it to normal operating temperature.
2. Stop the generator set.
3. With the engine still warm, drain the oil from the
crankcase.
4. Remove and replace the oil filter.
5. Refill the crankcase with oil suited to the climate.
6. Run the generator set for two minutes to distribute
the clean oil.
7. Stop the generator set.
8. Check the oil level and adjust, if needed.
2.8.2

Fuel System

Prepare the fuel system for storage as follows:
1. Start the generator set.
2. With the generator set running, shut off the gas
supply.
