Battery Service
The battery is the heart of the electrical system. With
regular and proper service, battery life can beextended.
Additionally, battery and electrical component failure
can be prevented.
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 when working w ith batteries.

Removal (Fig. 30 and 31)
IMPORTANT: Be careful not to damage terminal
posts or cable connectors when removing the bat-
tery cables.
1. Remove battery cover from the frame. Loosen bat-
tery retainer securing the back of the battery to the bat-
tery support.
2. Loosen nut on ground cable (--) first and remove
ground cable from battery. This should prevent shortcir-
cuiting the battery, other components or the operators
hands.
3. Loosen nuton positive cable (+) and removepositive
cable from battery.
4. Make sure battery vent caps are on tightly.
5. Remove battery from the battery compartment to a
service area to allow better access for service.
Inspection, Maintenance and Testing
1. Perform the following inspections and maintenance:
A. Check for cracks. Replace battery if cracked or
leaking.
B. Check battery terminal posts for c orrosion. 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.
C. 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 over-
filling. Also, check battery case for dirt and oil. Clean
the battery with a solution of baking soda and water,
then rinse it with clean water.
D. Check that the cover seal is not broken away. Re-
place the battery if the seal is broken or leaking.
E. Check the electrolyte level in each cell.If the level
is below the tops of the plates in any cell, fill all cells
with distilled water between the minimumand maxi-
mum fill lines. Charge at 15 to 25 amps for 15 min-
utes to allow sufficient mixing of the electrolyte.
