DO NOT lay tools on top of the battery.
The acid in the electrolyte can cause injury. If the
electrolyte is spilled, make the acid neutral with a
solution of sodium bicarbonate (soda) and water,
then flush the area with water. Acid in the eyes
must be immediately
continuously for 15 minutes, then seek medical
attention.
Batteries generate explosive fumes. Keep the
vents in the caps clean. Keep sparks or open
flames away from the battery area. DO NOT make a
spark from the battery connections. Disconnect
the battery when performing maintenance.
The battery must fit the battery compartment so
the battery restraint panels will operate correctly.
Use spacers to prevent the battery from moving
more than 13.0 mm (0.5 in.) in any direction.
NOTE: Battery water levels can be maintained without
removing the battery from the truck.
Check for loose or broken electrical connections and
damaged wires or cables. Examine the battery case
for damage and leakage. See the battery dealer in the
area to repair any damage to the battery or cables.
Check that the vent caps are clear. Check the level of
the electrolyte daily on a minimum of one cell. Add
only distilled water, as necessary, if the cell is low. If
one cell is low, check the rest of the cells. The correct
level is halfway between the top of the plates and the
bottom of the fill hole. Use a hydrometer to check that

case, connector, and cables for damage, cracks, or
breaks. See the battery dealer in your area to repair
any damage. Keep the battery case and the battery
compartment clean and painted. Leaks and corrosion
from the battery can cause a malfunction in the electric
controls of the lift truck. Use a water and soda solution
to clean the battery and the battery compartment.
Keep the top of the battery clean, dry, and free of
corrosion.
Make sure the battery is the correct weight and voltage
size. Prevent side-to-side movement of the battery by
adjusting the brackets on either side of the battery.
The correct battery is specified in How to Change the
Battery and in the Operating Manual. The Operating
Manual is located in the container on the Drive Unit
cover. This is a permanent reference and must be
available for use at all times.
