MACHINE CONTROL PANEL S28, S33 & S38
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 battery is being charged when the charger is plugged into an AC outlet. It also
indicates the amount of charge that is left in the batteries while the machine is in use. When the battery charger 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.
