Be careful when removing the battery cables and ensure that you do
not damage the terminal posts or cable connectors.
1. Unlatch, raise the hood and support it.
2. Loosen and remove the negative (-) cable from the battery. After you
disconnect the negative cable from the battery, loosen and remove the
positive cable (+) from the battery.
3. Loosen the flange nut that secures the battery retainer.
4. Carefully remove the battery from the machine.
5. Install the battery in reverse order and ensure to connect and tighten the
positive (+) cable to the battery before connecting negative (-) cable. Use 2
wrenches when tightening the cables.
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 negative (ground) cable connector. The reading should be less than 0.1
A. If the reading is 0.1 A or more, the electrical system of the machine should
be tested for short circuits or damaged components and repaired.
6. Lower the hood and secure it with the latches.
1. Do the following inspections and maintenance:
A. Check for cracks. Replace the battery if cracked or leaking.
B. Check the battery terminal posts for corrosion. Use the wire brush to
clean corrosion from the posts.
Before cleaning the battery, tape or block the vent holes of the
filler caps and ensure that the caps are tight.
C. Check for the 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 the battery case for dirt and oil. Clean
the battery with a solution of baking soda and water, then rinse it with
clean water.
D. Check that the cover seal is not broken away. Replace the battery if the
seal is broken or leaking.
E. Check the electrolyte level in each cell. If the level is below the tops of
the plates in any cell, fill all the cells with distilled water between the
minimum and maximum fill lines. Charge at 15 to 25 A for 15 minutes to
allow sufficient mixing of the electrolyte.
2. Perform the hydrometer test of the battery-electrolyte.
Ensure that the area around the cells is clean before opening the
battery caps.
