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.
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 machine. Electrolyte could be
spilled on other parts and cause corrosion.
3. Remove the vent caps from the battery (Fig. 61).
4. Slowly pour distilled water into each battery cell until
the level is up to the upper line (Fig. 61) 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 (Fig. 61) on the battery
case.
6. Reinstall battery vent caps.
Charging the Battery
Warning
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks
and flames away from battery.
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, page 48.
2. Check the electrolyte level; refer to Checking
Electrolyte Level, page 47.
3. Make sure the filler caps are installed in battery.
Charge battery for 10 to 15 minutes at 25 to 30 amps
or 30 minutes at 4–6 amps.
4. When the battery is fully charged, unplug the charger
from the electrical outlet, then disconnect the charger
leads from the battery posts (Fig. 63).

5. Install the battery in the machine and connect the
battery cables; refer to Installing the Battery on
page 48.
Note: Do not run the machine with the battery
disconnected, electrical damage may occur.
Adjusting the Mower Level
1. Position mower on a flat surface. Stop the engine, set
the parking brake, remove the key and disconnect the
spark plug wire(s) from the spark plug(s).
2. Check tire pressure of all four (4) tires. If needed,
adjust to 13 psi (90 kPa)
3. Set anti–scalp rollers to top holes or remove them
completely for this adjustment.
4. Raise the deck to the transport position and take all
force off of the two large deck lift springs by loosening
nut in front of each spring (Fig. 64).
