HOW TO PREPARE THE MACHINE FOR OPERATION

How To Install The Batteries

The 38, 33 and 28 Encore machines use six 6-volt or

three 12-volt batteries. The batteries are located in

the battery compartment under the recovery tank.

To Install the batteries, follow this procedure:

1. Turn key switch off.

2. Make sure both tanks are empty.

3. Disconnect the hoses from the recovery tank

(upper tank) & unplug the vac motor.

Remove the recovery tank.

4. Place the batteries in the solution tank as

shown in figures 8a - 8d.

WARNING: Lifting batteries without

help could result in an

injury. Get help to lift the

batteries. The batteries are

heavy.

WARNING: Working with batteries can

be dangerous. Always

wear eye protection and

protective clothing when

working near batteries.

NO SMOKING!

6. Join the connector from the battery pack to

the connector on the control panel. See

figure #9.

7. Install the tank, reconnecting hoses and

replace the two screws attaching the

solution tank to the rear of the frame.

NOTE: Charge the batteries before using the

machine.

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 dan-

gerous. Always wear eye protec-

tion 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 figure #10.

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,

Figure #34

Figure #35

1.Turn "ON" the key switch.

2. Start with the brush head up/down switch in the "Up"

position and the brush pressure knob set to minimum,

fully counter clockwise. This should cause the brush

head to be in the full "Up" position.

3. Install the proper brushes or pads and pad drivers for

the machine.

4. Leave the brush pressure knob set to minimum, fully

counter clockwise. Switch the brush head up/down

switch to the "Down" position. This should cause the

brush head to travel down to the floor until the brush

position switch (47422A) is closed. At this time the

brush head actuator will stop running down.

5. Check at the front of the machine to see if the brushes

or pads are completely flat on the floor. The screw, that

goes through the brush head actuator tube (69188A),

should be at the top of the 1.25 inch slot in the tube. If

the brushes or pads are not on the floor, or the screw

is not at the top of the slot, the brush position switch

(47422A) needs to be loosened and moved up or down

in the slot on the switch mount bracket (65972A).

Retighten the brush position switch.

6.Keep the brush pressure knob set to minimum, fully

counter clockwise. The brush head will need to be

raised and lowered again with the brush up/down

switch. Check to see if the adjustment put the brushes

or pads on the floor and kept the screw at the top of the

tube. If no, repeat step #5 until this step is completely

accomplished.

Replacing a Defective Brush Head Hall Affect Sensor
