HOW TO PREPARE THE MACHINE FOR OPERATION
Battery Maintenance
The electrical power to operate the machine comes from the storage
batteries. Storage batteries need preventive 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” 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 #7.
NOTE: Check the level of electrolyte prior to charging the batteries. Be
sure the plates in each cell are covered with electrolyte . 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 the electrolyte level
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 fi lled above the bottom of the tube
in each cell. 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!
Tap water may contain contaminants that will damage batteries.
Batteries must be re-fi lled with distilled water only.
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.
