Battery Service - Toro Multi Pro 1750 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 or
eyes. Always wear safety goggles and a face
shield when working with batteries.
Battery Specifications
BCI Group 26 Battery
300 Amp Cranking Performance at 0
28 minute Reserve Capacity at 80
Electrolyte Specific Gravity (fully charged): from 1.250
to 1.280
Electrolyte Specific Gravity (discharged): 1.240
Battery Removal (Fig. 94)
1. Park machine on a level surface, stop spray pump,
stop engine and engage parking brake. Remove key
from ignition switch.
2. Disconnect negative (black) cable from battery first
to prevent short circuiting the battery, other components
or operator's hands. Then disconnect positive (red)
cable.
3. Remove flange nuts and battery hold down rod.
4. Make sure that battery filler caps are on tightly.
5. Remove battery from chassis to a service area. This
will minimize possible battery damage and allow better
access for battery inspection and service.
Battery Installation (Fig. 94)
1. Make sure the key is removed from ignition switch.
2. Position the battery on the battery base with its posts
toward the right side of the machine.
3. Secure positive cable (red) to positive battery post
with cap screw and flange nut.
4. Connect a digital multimeter (set to amps) between
the negative battery post and the negative cable (black)
connector. The reading should be less than 0.1 amp. If
the reading is 0.1 amp or more, the electrical system
should be tested and repaired.

5. Secure negative cable (black) to negative battery
post with cap screw and flange nut.
6. Secure the battery to the machine with flange nuts
and battery hold down rod. Do not over tighten flange
nuts.
7. Apply battery terminal protector (see Special Tools in
this chapter) on battery posts and cable connectors to
reduce corrosion after connections are made.

Battery Inspection and Maintenance
1. Check battery for cracks. Replace battery if cracked
or leaking.
2. Check battery terminal posts for corrosion. 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.
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.
