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 Removal (Fig. 157)
IMPORTANT: Be careful not to damage battery ter-
minal posts or cable connectors when removing the
battery cables.
1. Make sure ignition and all accessories are OFF.
2. Loosen strap and remove battery box cover from
machine.
3. Using two (2) wrenches, loosen cap screw and nut
on ground (−) cable connector first and then remove
ground (−) cable from battery. This should prevent short
circuiting the battery, other components or the opera-
tor’s hands.
4. Loosen cap screw and nut on positive (+) cable con-
nector using two (2) wrenches. Remove positive (+)
cable from battery.
5. Make sure battery vent caps are on tightly.
6. Remove battery from the battery box and machine.
Battery Installation (Fig. 157)
IMPORTANT: To prevent possible electrical prob-
lems, install only a fully charged battery.
1. Make sure ignition and all accessories are OFF.
2. Make sure that battery box is clean and that battery
cables and connections are in good condition.
3. Place battery into battery box and make sure battery
is level and flat.
4. Connect positive (+) cable connector onto positive
battery post. Tighten cap screw and nut using two (2)
wrenches.
5. Connect a digital multimeter (set to amps) between
the negative battery post and the ground (−) cable con-
nector. The reading should be less than 0.1 amp. If the
reading is 0.1 amp or more, the unit’s electrical system
should be tested and repaired.
6. Connect ground (−) cable connector to the negative
battery post. Tighten cap screw and lock nut using two
(2) wrenches.
7. Coat battery posts and cable connectors with Battery
Terminal Protector (Toro Part No. 107−0392) or petro-
leum jelly to prevent corrosion.
8. Install battery cover and secure with strap.
