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 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 electrolyte each time you charge the
batteries. See fi gure 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 overfl ow 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 fi lled.
Do not fi ll 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
installation.
CAUTION: Batteries must be refi lled 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 bicarbonate of soda to get into batteries.
3. Keep the batteries charged.
4. To drain battery compartment: (See fi gure 7)
a. Always wear protective eye protection and protective 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 fl ange and open valve.
e. When empty, close valve.
f. Neutralize any acid spills with ammonia or bicarbonate of soda.
