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.

 

 

 

 

 

 

Correct Fill

 

 

 

 

 

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

Figure 4

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 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 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

 

 

 

 

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 bicarbonate of soda to get into the batteries.

3.Keep the batteries charged.
