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 and Installation (Fig. 33)
1. Remove battery cover from the frame. Loosen bat-
tery retainer securing the back of the battery to the bat-
tery support.
2. Loosen nut on ground cable (--) post first and remove
cable from battery. This should prevent short circuiting
the battery, other components, or the operators hands.
3. Loosen nut on positive (+) cable post and remove
cable from battery.
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 the negative cable.
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.
6. Make sure that rubber boot is properly placed over
positive cable end and positive battery post.
7. Install and secure battery cover after installing bat-
tery.

Battery Inspection and Maintenance
1. Replace battery if case is 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.
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 fifteen (15) minutes
to allow sufficient mixing of the electrolyte.
