Key Switch (See Figure #1, Item "A")

The key switch turns "ON" the power to the control panel. "0" is "OFF" and "I" is "ON". Traverse Speed Switch (See Figure #1, Item "B")

The speed control varies from low to high speed. To increase the speed, turn the knob to the right. To decrease the speed, turn the knob to the left.

Brush Up/Down Switch (See Figure #1, Item "C") The brush switch has two positions: "Up" positions the brushes up; "Down" positions the brushes on the floor. The brush motors start when the brushes are down and the traverse switch is depressed.

Increase Brush Pressure Switch (See Figure #1, Item D) This switch is used to increase the brush pressure. Increased brush pressure may be required when stripping or cleaning heavily soiled floors. To increase brush pressure, first lower the brushes by pressing the brush up/down switch (Item "C") to the down position. This will lower the brushes to the normal scrub position. To increase brush pressure, press and hold the switch (Item "D") until the desired brush pressure is reached or the brush deck stops moving downward. To reposition the brush pressure to normal scrub, press the brush up/down switch (Item "C") to the up position and after the brush deck is completely raised, then return the switch to the down position for normal scrub.

Solution Control Knob (See Figure #1, Item "E") The solution control knob regulates the flow of cleaning solution to the floor. To increase the flow turn the knob clockwise. To decrease the flow, turn the knob counter-clockwise.

Forward Switch (See Figure #1, Item "F") The forward switch turns the traverse motor "on" and if the brush motors are in the down position, it also activates the brush motors and solution control module. Either the right or the left switch can be used.

Reverse Switch (See Figure #1, Item "G") The reverse switch, when used in conjunction with one of the forward switches, causes the machine to reverse direction. The reverse speed is 70% of the forward speed.

Charge / Battery Meter (See Figure #1, Item "H") The charge/battery meter indicates the amount of charge that is left in the batteries while the machine is in use. When the battery pack gets too low the red light will begin flashing and the brush/pad motors will shut off.

Circuit Breakers (See Figure #1, Item "I"-"M") The circuit breaker reset buttons are located on the control panel. The breakers are located as follows: Item I & J Brush Motors (35A); Item K - Traverse Motor (30A); Item L - Vac Motor (25A); Item M - Actuator Motor, Brush Head (5A)

If a circuit breaker trips, determine which motor is not operating and turn the key switch "OFF". Wait five minutes and push the reset button back in. Turn the key switch "ON", and try again. An authorized service person should be contacted if the breaker trips again.

Hour Meter (See Figure #1, Item "N") The hour meter indicates the number of hours the machine has operated. It runs only when the machine is moving forward or reverse.

The speed control varies from low to high speed. To increase the speed, turn the knob to the right. To decrease the speed, turn the knob to the left.

Squeegee Up/Down Switch (See Figure #2, Item "C") The squeegee switch is used to raise and lower the squeegee and to turn on and off the vacuum motor. The squeegee will lower and the vacuum motor will turn on when the switch is placed in the lower position. To raise the squeegee, place the switch in the up position. The vacuum motor will stop, after a short delay, when the switch is placed in the up position.

The middle switch position is used for the one touch control. The squeegee will raise and lower and the vacuum will turn on and off automatically when the one touch control function is used. NOTE: The squeegee switch must be in

the middle position for the squeegee and vacuum to operate properly with the one touch feature. Brush Up/Down Switch (See Figure #2, Item D)

To lower brush head, push the brush switch in the down (+) position. To increase brush pressure, continue to push the brush switch in the down (+) position until the desired pressure is reached or until brush head travel stops. The brush motors will start and solution will flow (provided the solution is turned "ON") when the machine begins to traverse. To raise the brush head, push the brush switch in the up (-) position until the brush head travel stops or desired position is reached.

Solution Flow Control (See Figure #2, Item "E") The solution flow switch regulates the flow of chemical solution to the floor. To increase the flow, push the solution flow switch in the down (+) position until desired flow is reached. To decrease the flow, push the solution flow switch in the up (-) position until the desired flow is reached. To shut off the solution, push the solution flow switch in the up (-) position until no indicators are visible on the display. NOTE: DO NOT run dry! NOTE: No solution will flow when

the machine does not traverse. Forward Switch (See Figure #2, Item "F")

The forward switch turns the traverse motor "on" and if the brush motors are in the down position, it also activates the brush motors and solution control module. Either the right or the left switch can be used.

Reverse Switch (See Figure #2, Item "G") The reverse switch, when used in conjunction with one of the forward switches, causes the machine to reverse direction. The reverse speed is 70% fo the forward speed.

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 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 6.35mm 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 #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 overflow 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.

Correct fill level

Figure #7

CAUTION: Machine damage and discharge

across the tops of the batteries can occur if the batteries are filled above the bottom of the tube in each cell. 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: Tap water may contain contami-

nants that will damage batteries. Batteries must be re-filled 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.
