MACHINE CONTROL PANEL L28, L33 & L38
Key Switch (See Figure #2 Item "A")
The key switch turns "ON" the power to the control panel. "O" is "OFF" and "I" is "ON".
Traverse Speed Switch (See Figure #2, 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.
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.
Charge Indicator Light (See Figure #2, Item "H")
When the charger is plugged into an AC Outlet, the charge green indicator light will flash on and off. When the batteries
become fully charged, the green indicator light will remain on until the charger is unplugged.
One Touch (See Figure #2, Item "I")
The one touch button is a green button that lowers and raises the brush head and squeegee with one touch. NOTE: For
more information about the one touch feature see the section "How to Operate the Machine".
LCD Display (See Figure #2, Item "J")
The main display indicates the state of battery charge, brush head, solution and squeegee status. It will also display
machine run hours and error codes. NOTE: When the battery charger gets too low the battery display will begin flashing
and the brush/pad motors will shut off.
Display Button (See Figure #2, Item "K")
Pressing the black display button will toggle between the main machine functions and the hour meter. The hour meter
indicates the number of hours the machine has operated. It displays brush motor, vacuum motor, traverse motor and
total key on hours.)
