HOW TO PREPARE THE MACHINE
FOR OPERATION
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 danger-
ous. 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 electrolyte each time you charge
the batteries. See figure 6.
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 batteries.
Never add acid to a battery after installa-
tion.
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 connec-
tor cleaning tool. Do not allow ammonia or bicarbonate
of soda to get into batteries.
3. Keep the batteries charged.
4. To drain battery compartment: (See figure 7)
a. Always wear protective eye protection and protec-
tive clothing.
b. Add a weak solution of ammonia or bicarbonate of
soda solution to battery compartment to neutralize
any spilled acid.
c. Locate drain hose behind the transaxle.
d. Place hand behind flange and open valve.
e. When empty, close valve.
f. Neutralize any acid spills with ammonia or bicarbon-
ate of soda.
