MACHINE CONTROL PANEL (L38, L33 & L28)
Key Switch (See Figure #2, Item "A")
The key switch turns "ON" the power to the control panel. "0" is "OFF" and "1" is "on".
Traverse Speed Control Knob (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.
Brush Head Up/Down Switch (See Figure #2, Item "C")
The brush switch has two positions: "Up" positions the brushes up; "Down" positions the brushes on the
floor. The brush motors will not run until the control handles are activated.
Brush Pressure Knob (See Figure #2, Item "D")
The brush pressure knob is used to increase the pressure on the brushes from the initial scrub position. Turn
the knob counter clockwise to decrease pressure. Trun knob clockwise to increase pressure.
Solution Control Knob (See Figure #2, 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.
Squeegee/Vacuum Switch (See Figure #2, Item "F")
The 3 position squeegee switch positions the squeegee either: (1) Up with vac motor "OFF", (2) Up with vac
motor "ON", or (3) Down with vac motor "ON". The squeegee will automatically raise up when the control
handles are pulled into reverse.
Control Handle (See Figure #2, Item "G")
The control handle controls the direction that the machine moves. It is at the back of the machine. Push
forward to go forward (see figure #3), pull back to move in reverse (see figure #4).
Note: The reverse speed is automatically reduced by approximately 30 percent. Releasing the
control handle to the center position applies a dynamic brake to the traverse motor to slow
the machine down. If the machine is scrubbing and the control handle is released, the
brush motors will stop after two seconds.
Battery Meter (See Figure #2, Item "H")
The battery meter indicates the relative charge on the battery pack. Do not continue to run the machine when
the meter is in "red" area. This will shorten the life of the battery.
Brush Pressure Meter (See Figure #2, Item "I")
The brush pressure meter indicates the relative amount of pressure the brushes or pads are putting on the
floor. To maximize run time on a battery charge, keep the light bars towards the center of the green area. To
avoid damage to the brush motors, do not run the machine in the "red" area.
Hour Meter (See Figure #2, Item "J")
The hour meter indicates the number of hours the machine has operated. It runs only when the machine is
moving forward or reverse.
