Battery Removal and Installation (Fig. 60)
1. Raise and support operator seat. Remove battery
access panel.
2. Loosen and remove negative cable frombattery.Af-
ternegative cableisremoved, loosenandremoveposi-
tive cable.
3. Loosen battery strap that secures battery to ma-
chine.
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 negative cable.
NOTE: Before connecting the negative (ground) cable
to the battery, connect a digital multimeter (set to DC
Amps)betweenthenegativebatterypostand thenega-
tive (ground) cable connector. The reading should be
lessthan0.1 amp. Ifthereading is 0.1 amp or more,the
machine’s electrical system should be tested for short
circuits or faulty components and repaired.
6. Secure battery with battery strap. Install battery ac-
cess panel. Lower and secure operator seat.

Battery Inspection, Maintenance and Testing
1. Perform 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 ofwetness or leakage on the top
ofthebatterywhichmightindicatealooseormissing
filler cap, overcharging, loose terminal post or over-
filling.Also, check battery case for dirtandoil. Clean
the battery with a solution of baking soda and water,
then rinse it with clean water.
D. Checkthatthecoversealisnotbrokenaway.Re-
place the battery if the seal is broken or leaking.
E. Checktheelectrolytelevelineachcell.Ifthelevel
is below the tops of the plates in any cell, fill all cells
withdistilledwaterbetweentheminimumandmaxi-
mum fill lines. Charge at 15 to 25 amps for 15 min-
utes to allow sufficient mixing of the electrolyte.
