2. Look at the side of the battery. The electrolyte must be
up to the "UPPER" line (Fig. 42). Do not allow the
electrolyte to get below the "LOWER" line (Fig. 42).
3. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery,
page 37.

Danger
Battery electrolyte contains sulfuric acid which is
a deadly poison and causes severe burns.
Do not drink electrolyte and avoid contact with
skin, eyes or clothing. Wear safety glasses to
shield your eyes and robber gloves to protect
your hands.
Fill the battery where clean water is always
available for flushing the skin.
Follow all instructions and comply with all
safety messages on the electrolyte container.
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. 42).
4. Slowly pour distilled water into each battery cell until
the level is up to the "UPPER" line (Fig. 42) 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. 42) 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 36.
2. Check the electrolyte level; refer to Checking
Electrolyte Level, page 36.
3. Make sure the vent caps are installed in the battery.
Charge the battery for 1 hour at 25 to 30 amps or 6
hours at 4 to 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 (Fig. 43).
