CAUTION
When working with batteries, use extreme cau-
tion to avoid splashing or spilling electrolyte.
Electrolyte can destroy clothing and burn skin
and eyes. Always wear safety goggles and a face
shield when working with batteries.

A. Check battery case for cracks. Replace battery if
cracked or leaking.
Removal and Installation (Fig. 16)
B. Checkbatteryterminalsforcorrosion.Ifcorrosion
occurs at terminals, disconnect cables. Always dis-
connect negative (--) cable first. Clean cable clamps
and battery terminals separately. Reconnect cables
with positive (+) cable first. Coat battery posts and
cable connectors with Battery Terminal Protector
(Toro Part No. 107--0392) or petroleum jelly to pre-
vent corrosion.

OFF position. Remove key from the ignition switch.
Loosen strap and remove battery box cover.
Make sure that Processor ignition switch is in the

ter negative cable has been removed, loosen and re-
move positive cable from battery.
Loosen and remove negative cable from battery. Af-
IMPORTANT: Before cleaning the battery, tape
or block vent holes to the filler caps and make
sure the caps are on tightly.

4.
Carefully remove battery from machine.
Install battery in reverse order making sure to con-
nect and tighten positive cable to battery before con-
necting negative cable. Tighten nuts that secure battery
cables from 10 to 15 ft--lb (14 to 20 N--m).
C. Check for signs of wetness or leakage on the top
ofthe battery which mightindicate aloose ormissing
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.
NOTE: Before connecting the negative (ground) cable
to the battery, connect a digital multimeter (set to DC
Amps) between the negative battery post and the nega-
tive (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 components and repaired.
D. Check thatthe cover seal is notbroken away.Re-
place the battery if the seal is broken or leaking.
E. Check theelectrolyte levelineachcell.Ifthelevel
is below the tops of the plates in any cell, fill all cells
with distilled water between the minimum and max-
imum fill lines. Charge at 15 to 25 amps for 15 min-
utes to allow sufficient mixing of the electrolyte.

Install battery box cover and secure with strap.
