Adding Water To The Battery; Charging The Battery - Toro 72211 Operator's Manual

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.
2. Clean the top of the battery with a paper towel.
Note: Never fill the battery with distilled water
while the battery installed in the tractor. Electrolyte
could be spilled on other parts and cause corrosion.
3. Remove the vent caps from the battery (Figure 46 ).

4. Slowly pour distilled water into each battery cell
until the level is up to the upper line (Figure 46 )
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 46 )
on the battery case.
6. Reinstall battery vent caps.

Charging the Battery

Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks
and flames away from battery.
3. Lower line
Important: Always keep the battery fully
charged (1.265 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
Electrolyte Level.
3. Make sure the filler caps are installed in battery.
Charge battery for a minimum of 6 to 10 amps for
one hour. If the battery is in the fully discharged
condition, then the charging requirement is 3 amps
for 6 hours.
Important: Never over charge the battery.
Excessive charging will shorten the battery life.
4. When the battery is fully charged, unplug the
charger from the electrical outlet, then disconnect
the charger leads from the battery posts (Figure 47 ).

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.
