Battery Service - Toro ProForce 44538 Service Manual

Battery Service

The battery is the heart of the electrical system. With
regular and proper service, battery life can be extended.
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
and eyes. Always wear safety goggles and a face
shield when working with batteries.

Battery Removal and Installation (Fig. 27)
1. Make sure that ignition switch is in the OFF position
and that none of the LED's on Remote Control Module
are illuminated. Loosen strap and remove battery box
cover.
2. Loosen and remove negative cable from battery. Af-
ter negative cable has been removed, loosen and re-
move positive cable.
3. Carefully remove battery from machine.
4. 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).
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.
5. Install battery box cover and secure with strap.

Battery Inspection and Maintenance
1. Check battery case for cracks. Replace battery if
cracked or leaking.
2. Check battery terminals for corrosion. If corrosion
occurs at terminals, disconnect cables. Always discon-
nect negative (--) cable first. Clean cable clamps and
battery terminals separately. Reconnect cables with
positive (+) cable first. Coat battery posts and cable con-
nectors with Battery Terminal Protector (Toro Part No.
107--0392) or petroleum jelly to prevent corrosion.
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 the 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 the level is
below the tops of the plates in any cell, fill all cells with
distilled water between the minimum and maximum fill
lines. Charge at 15 to 25 amps for 15 minutes to allow
sufficient mixing of the electrolyte.
