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.

NOTE: Before connecting the negative (ground) cable,
connect a digital multimeter (set to amps) between the
negative battery post and the negative (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 com-
ponents and repaired.
5. Make sure that rubber boot is properly placed over
positive cable end and positive battery post.
