How To Prepare the Machine For Operation
Battery Maintenance
The electrical power to operate the machine comes from the storage bat-
teries. 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 4).
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 the batteries.
3. Keep the batteries charged.
