Additionally, battery and electrical component failure
can be prevented.
CAUTION
When working with batteries, use extreme cau-
tion to avoid splashing or spilling electrolyte.

Battery Removal and Installation (Fig. 48)
1. Unlatch and raise operator’s console panel behind
the operator seat to access battery.
2. Loosen and remove negative cable from battery. Af-
ternegativec able is removed,loosenandremoveposi-
tive cable from battery.
3. Loosen strap that secures battery to machine.
4. Carefully remove battery from machine.
5. Install battery in reverse order making sure to con-
nect and tighten positive c able to battery before con-
necting the negative c able.
NOTE: Beforeconnectingthenegative(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
thereading is 0.1 amp or more, the machine’selectrical
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. Lower and secure operator’s console panel.
1. Negative cable
2. Positive cable
3. Battery strap

Battery Inspection and Maintenance
1. Replace battery if case is cracked or leaking.
2. Check battery terminalposts for corrosion.Use wire
brush to clean corrosion from posts.
IMPORTANT: Before cleaning the battery, tape or
blockvent holes tothe fillercaps andmake surethe
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 s olution ofbaking soda and water,thenrinse
it with clean water.
4. Check that the cover seal is not broken away. R e-
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
distilledwaterbetween the minimum and maximumfill
lines. Charge at 15 to 25 amps for fifteen (15) minutes
to allow sufficient mixing of the electrolyte.
