forward once depressed. This also allows the operator to automatically load the brush when the scrubdeck is lowered.
Handle Adjustment Knobs
(B) Allows the handle position to be raised or lowered.
Key Switch
(C) Controls the machine’s power (Brush Unload/Off/On) with a key for safety. This switch, when turned counter clock-
wise, operates the auto brush unload when scrubdeck is in the raised position. When it is turned to the on position, the
machine will operate.
Squeegee Lift Lever
(D) When actuated to the top position, the squeegee is lowered and the vacuum motor is turned on. When locked in
the bottom position, the squeegee is raised and the vacumm motor shuts off.
Solution Control Lever
(E) This lever controls the rate at which solution is put down. Moving the lever up will increase the amount of solution.
Moving the lever down will decrease the solution rate. Moving the lever all the way down shuts off solution flow.
Battery Gauge
(F) This gauge displays the remaining battery charge.
Charge Status Indicator
(G) This gauge displays the status of the batteries during charging. The gauge has a readout of 3 LEDs. 1 Green, 1
yellow, 1 Red. Green indicating a full charge, Red indicating the batteries are charging.
