Servicing The Fuses - Toro 74603 Operator's Manual

2. Look at the side of the battery. The electrolyte
must be up to the Upper line (Figure 31).
Do not allow the electrolyte to fall below the
Lower line (Figure 31).

3. If the electrolyte is low, add the required
amount of distilled water; refer to Adding
Water to the Battery.
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 tractor; refer to
Removing the Battery.
Important: Never fill the battery with
distilled water while the battery installed in
the tractor. 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 31).
4. Slowly pour distilled water into each battery
cell until the electrolyte level is up to the Upper
line (Figure 31) 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 31) 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 32).

5. Install the battery in the tractor and connect the
battery cables; refer to Installing the Battery.
Note: Do not run the tractor with the battery
disconnected, electrical damage may occur.
