MACHINE CONTROL PANEL 770S, 784S & 795S
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 fl oor. 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 fl oors. To increase brush pressure, fi rst 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 fl ow of cleaning solution to the fl oor. To increase the fl ow turn the knob clockwise. To
decrease the fl ow, 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 (Solo) (See Figure #1, Item “H1”)
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
fl ashing and the brush/pad motors will shut off.
Battery Meter / Charge Indicator Light (I-Drive) (See Figure #1, Item “H2”)
The battery meter indicates the amount of charge remaining in the batteries while the machine is in use.
When the charger is plugged into an AC Outlet, the charge green indicator light will fl ash on and off. When the batteries become fully charged, the
green indicator light will remain on until the charger is unplugged.
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 fi ve 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.
