Battery Service
The battery is the heart of the e lectrical system. With
regular and proper service, battery life can be extended.
Additionally, battery and electrical component failure
canbeprevented.
CAUTION
When working with batteries, use extreme cau-
tion to avoid splashing or spilling electrolyte.
Electrolyte can destroy clothing and burn skin or
eyes. Always wear safety goggles and a face
shield w hen working with batteries.

Battery Removal and Installation (Fig. 62)
1. Unlatch and raise operator’s console panel behind
the operator seat to access battery.
2. Loosen and remove negative cable from battery. Af-
ter negative cable is removed, loosen and remove posi-
tive cable from battery.
3. Loosen strap that secures battery to machine.
4. Carefully remove battery from machine.
5. Install battery in reverse order making sure to con-
nect and tighten positive cable to battery before con-
necting the negative cable.
NOTE: Before connecting the negative (ground) cable,
connect a digital multimeter (set to amps) between the
negative battery post and the negative (ground) cable
connector. The reading should be less than 0.1 amp. If
the reading is 0.1 amp or more, the machine’s electrical
system should be tested for short circuits or faulty com-
ponents and repaired.
6. Make sure that rubber boot is properly placed over
positive cable end and positive battery post.
7. Lower and secure operator ’s console panel.
1. Negative cable
2. Positive cable

Battery Inspection and Maintenance
1. Replace battery if case is cracked or leaking.
2. Check b attery terminal posts for corrosion. Use wire
brush to clean corrosion from posts.
IMPORTANT: Before cleaning the battery, tape or
block vent holes to the filler caps and make sure the
caps are on tightly.
3. Check for signs of wetness or leakage on the top of
the battery which might indicate a loose or missing filler
cap, overcharging, loose terminal post or overfilling.
Also, check battery case for dirt and oil. Clean t he bat-
tery with a solution of baking soda and water, then rinse
it with clean water.
4. Check that the cover seal is not broken away. Re-
place the battery if the seal is broken or leaking.
5. Check the electrolyte level in each cell, if possible. If
the level is below the tops of the plates in any cell, fill all
cells with distilled water between theminimum and max-
imum fill lines. Charge at 15 to 25 amps for fifteen (15)
minutes to allow sufficient mixing of the electrolyte.
