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.
Note: Never fill the battery with distilled water while the
battery installed in the machine. The electrolyte could be
spilled on other parts and cause corrosion.
1. Remove the battery from the machine.
2. Clean the top of the battery with a paper towel.
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 5 to 10 minutes after filling the battery cells, then
add distilled water, if necessary, until the electrolyte
level is up to the upper line (Fig. 61) on the battery
case.
6. Install 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 the 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 on page 45.
2. Ensure that the filler caps are installed in battery.
3. Charge battery for a minimum of 1 hour at 6 to
10 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).
