Battery Service
The battery is the heart of the electrical system. With
regular and proper service, battery lifecan 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.
Electrolytecan destroy clothingand burn skinor
eyes. Always wear safety goggles and a face
shield when working with batteries.

Battery Removal and Installation (Fig. 85)
1. Open battery cover to access battery.
2. Loosen and remove negative cable from battery. Af-
ter negative cable is removed, loosen and remove posi-
tive cable.
3. Loosen battery retainer and then 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.
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. Secure battery to machine with battery retainer.
Close battery cover.

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.
5. If the battery electrolyte is accessible, check the
electrolyte levelin each cell. If the level is below the tops
of the plates in any cell, fill all cells with distilled water
betweenthe minimumand maximum fill lines.Charge at
15 to 25 Amps for fifteen (15) minutes to allow sufficient
mixing of the electrolyte.
