Servicing The Fuses - Toro 74402 Operator's Manual

1. Tip the seat forward to see the battery.
2. Look at the side of the battery. The electrolyte
must be up to the Upper line (Figure 32 ). Do not
allow the electrolyte to fall below the Lower line
(Figure 32 ).

3. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery
in Electrical System Maintenance, page 26.
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 26.
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 32 ).
4. Slowly pour distilled water into each battery cell
until the electrolyte level is up to the Upper line
(Figure 32 ) 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 32 )
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).
3. Lower line
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 34 ).

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 32 ).
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 32 ).
5. Slide the red terminal boot onto the positive (red)
battery post.
6. Secure the battery with the hold-down (Figure 32 ).

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.
