Maintenance

Battery Inspection

NOTE: 

Remove five amp controller fuse from control 

panel.

An authorized operator should inspect the engine battery

monthly. At this time, the battery fluid level should be
checked using a load tester and distilled water added if
needed. Battery cables and connections should also be
inspected for cleanliness and corrosion.
Once every six months, an IASD should inspect the
battery system. At this time, the battery condition and
state of charge should be checked using a load test
battery. The battery should be recharged or replaced as
required.
Battery service is to be performed or supervised by
personnel knowledgeable of batteries and the required

precautions. Keep unauthorized personnel away.
Observe the following precautions when working on
batteries:

Remove watches, rings, or other metal objects.

Use tools with insulated handles.

Wear rubber gloves and boots.

Do not lay tools or metal parts on top of battery.

Disconnect charging source prior to connecting or

disconnecting battery terminals.

NOTE: 

Spilled electrolyte is to be washed down with an 

acid neutralizing agent. A common practice is to use a 
solution of one pound (454 grams) bicarbonate of soda 
(baking soda) to one gallon (3.8 liters) of water. The 
bicarbonate of soda solution is to be added until the evi-
dence of reaction (foaming) has ceased. The resulting 
liquid is to be flushed with water.

NOTE: 

Discharge static electricity before touching bat-

tery by first touching a grounded metal surface.

Battery Installation and Replacement

When required, the battery must be replaced with one of
equivalent size, voltage, and CCA (cold crank amp
capacity). Minimum CCA for this unit is 2200 (2 pairs of 2
1100 CCA 12 volt batteries in series to give 1100 Amps at
24 volts. connected in parallel to provide 2200 CCA at 24
volts). Contact the local IASD for correct battery size. A
new battery must be filled with the proper electrolyte and
be fully charged before install.
Battery cables are connected to the unit at the factory.
Connect cables to battery posts as follows.

1.

Connect battery cable from starter contactor to 
positive (POS or +) battery post.

2.

Connect black battery cable to negative (NEG or -) 
battery post.

3.

Refer to 

Engine and Heater Startup

.

Other Maintenance Checks

The following inspections should be performed by an
authorized service technician, or a properly trained
authorized operator. These maintenance items require a
high level of experience and skill to evaluate and correct.

Inspect engine accessory drive belts

Inspect hoses and connections

Inspect fuel supply system

Inspect exhaust system

Inspect exhaust pipe sleeve
