Adding Water to the Battery
The best time to add distilled water to the battery is
just before you operate the machine. This lets the
water mix thoroughly with the electrolyte solution.
1. Remove the battery from the machine;
refer to Removing the Battery in
Electrical System Maintenance, page 34.
Important: Never fill the battery with
distilled water while the battery is installed
in the machine. Electrolyte could be
spilled on other parts and cause corrosion.
2. Clean the top of the battery with a paper towel.
3. Remove the vent caps from the battery
(Figure 42).
4. Slowly pour distilled water into each battery
cell until the electrolyte level is up to the Upper
line (Figure 42) on the battery case.
Important: Do not overfill the battery
because electrolyte (sulfuric acid) can
cause severe corrosion and damage to the
chassis.
5. Wait five to ten minutes after filling the battery
cells. Add distilled water, if necessary, until
the electrolyte level is up to the Upper line
(Figure 42) on the battery case.
6. Reinstall the battery vent caps.
Charging the Battery
Important: Always keep the battery
fully charged (1.260 specific gravity). This
is especially important to prevent battery
damage when the temperature is below 32°F
(0°C).
1. Remove the battery from the chassis; refer to
Removing the Battery.
2. Check the electrolyte level; refer to Checking
the Electrolyte Level.
3. Make sure that the vent caps are installed in
the battery. Charge the battery for 1 hour at 25
to 30 amps or 6 hours at 4-6 amps. Do not
overcharge the battery.
4. When the battery is fully charged, unplug
the charger from the electrical outlet, then
disconnect the charger leads from the battery
posts (Figure 43).

5. Install the battery in the machine and connect
the battery cables; refer to Installing the
Battery.
Note: Do not run the machine with the
battery disconnected, electrical damage may
occur.
Installing the Battery
1. Position the battery in the tray with the
terminal posts away from the control panel
(Figure 41).
2. Install the positive (red) battery cable to the
positive (+) battery terminal.
3. Install the negative battery cable to the negative
(-) battery terminal.
4. Secure the cables with 2 bolts (1/4 x 3/4 inch),
washers (1/4 inch), and nuts (1/4 inch)
(Figure 41).
5. Slide the red terminal boot onto the positive
(red) battery post.
6. Secure the battery with the hold-down
(Figure 41).

Servicing the Fuses

The electrical system is protected by fuses. It
requires no maintenance; however, if a fuse blows,
check the component/circuit for a malfunction
or short.
Fuse:
• Main F1-30 amp, blade-type
• Charge Circuit F2-25 amp, blade-type
