Battery Service
The battery is the heart of the electrical system. With
regularand proper service,battery lifecan 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 with batteries.

Battery Removal and Installation (Fig. 57)
1. Raise and support hood.
2. Loosen and remove negative (--) cable from battery.
After negative (--) cable is removed, loosen and remove
positive (+) cable.
3. Loosen flange nut that secures battery retainer.
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) between the negative battery postand 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.
6. Lower and secure hood.
Battery Inspection and Maintenance
1. Perform the following inspections and maintenance:
A. Check battery case for cracks. Replace battery if
cracked or leaking.
1. Battery
2. Battery tray
3. Retainer
4. Flange nut
5. Carriage screw
6. Negative battery cable
7. Positive battery cable
8. Fusible link

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.
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
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.
D. Check that the cover seal is not broken away. Re-
place the battery if the seal is broken or leaking.
E. Check theelectrolyte level ineach cell. 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 (see
battery charging in this section).
