Battery Maintenance
The electrical power to operate the machine comes
from the storage batteries. Storage batteries need
preventative maintenance.
WARNING: Working with batteries can
be dangerous. Always wear
eye protection and protective
clothing when working near
batteries. NO SMOKING!
To maintain the batteries in good condition, follow
these instructions:
1. Keep the electrolyte at the correct level. The
correct level is between 1/4" (1/2 cm) below the
bottom of the tube in each cell and above the
tops of the plates. Check the level of the electro-
lyte each time you charge the batteries. See
figure 10.
NOTE: Check the level of electrolyte prior to charging
the batteries. Be sure the plates in each cell are
covered with electrolyte before charging. Do not top
off the cells prior to charging the battery. Electrolyte
expands during charging. As a result, the electrolyte
could overflow from the cells. Always top off the cells
with distilled water after charging.
CAUTION: Irreversible damage will occur to
the batteries if electrolyte does
not cover the plates. Keep the
electrolyte at the correct level.
CAUTION: Machine damage and discharge
across the tops of the batteries
can occur if the batteries are over
filled. Do not fill the batteries up
to the bottom of the tube in each
cell. Wipe any acid from the
machine or the tops of the batter-
ies. Never add acid to a battery
after installation.
CAUTION: Batteries must be refilled with
distilled water only. Do not use
tap water as it may contain
contaminants that will damage
batteries.
2. Keep the tops of the batteries clean and dry.
Keep the terminals and connectors clean. To
clean the top of the batteries, use a damp cloth
with a weak solution of ammonia or bicarbonate
of soda solution. To clean the terminals and
connectors, use a terminal and connector
cleaning tool. Do not allow ammonia or bicar-
bonate of soda to get into batteries.

3. Keep the batteries charged.
4. To drain battery compartment: (See figure 11)
a. Always wear protective eye protection and
protective clothing.
b. Add a weak solution of ammonia or bicarbon-
ate of soda solution to battery compartment to
neutralize any spilled acid.
c. Pull drain hose out from under transaxle.
d. Place hand behind flange and open valve.
e. When empty, close valve.
f. Replace valve and drain hose on top of
transaxle.
g. Neutralize any acid spills with ammonia or
bicarbonate of soda.
