Operating the Machine

10 ENGLISH

1	Follow the instructions in the Preparing the
	Machine for Use section of this manual.
2	Make sure the Solution Fill Cap (22) and the
	Recovery Tank Dome Lid (2) are firmly in place.

3Make sure the Pump Switch (5) and the Vacuum

	Switch (6) are both in the AUTO position.
4	Turn the Master Key Switch (4) ON.
5	Adjust the Nozzle Selector Knob (25) to either the

“maintenance” or “restoration” mode. Set the

Speed Control Knob (9) to the corresponding
Speed Control Knob (9) to the corresponding
“maintenance” or “restoration” setting.

6Lower the Brush Deck (20) to the floor using the Brush Deck Lift Lever (12).

7	When the Drive Paddle (11) is in the neutral
	position, the brush does not run and solution is
	not dispensed. Grip the Operator Control
	Handle (10) and push the Drive Paddle (11)
	forward to start the brush motor and the solution,
	and to move the machine forward. For best

results, move the machine at full speed assuming that step 5 has been completed. Pull the Drive Paddle (11) backward to move the machine in reverse. The brush will turn in the opposite direction while moving the machine in reverse, and solution will not be dispensed.

8Begin cleaning by driving the machine forward in a straight line and overlap each pass by 2 inches (5 cm). Turn the Pump Switch (5) OFF prior to turns to ensure complete extraction of solution from carpet. Guide the right side of the machine along the wall when cleaning the perimeter of the room.

9Watch the fluid entering the Recovery Tank Dome Lid (2). If there is a large amount of suds in the recovery tank, add a defoamer chemical to the recovery tank.

CAUTION!

Empty the recovery tank before the fluid or foam enters the Vacuum Hose (23) at the rear of the Recovery Tank Dome Lid.

If there is little or no fluid entering the recovery tank, check the Solution Drain Hose / Level Indicator (21), the solution tank may be empty. Refill the solution tank with water and the proper ratio of cleaning chemical.

10The recovery tank has an Automatic Float Shut-Off (33) to block the vacuum system when the recovery tank is full. You can tell when the float closes by the sudden change in the sound of the vacuum motors. When the float closes, the recovery tank must be emptied. The machine will not pick up water with the float closed.

11When the operator wants to stop cleaning or the recovery tank is full, raise the Brush Deck Lift Lever (12). This will automatically stop the brush, pump and vacuum motors.

12Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (17) from it’s rear storage area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). Refill the solution tank and continue cleaning.

USING ATTACHMENTS

To use accessory tools, attach the accessory recovery hose to the front port of the Recovery Tank Dome Lid (2). Attach the accessory solution hose to the Accessory Port (14). Connect the other ends of the hoses to the accessory tool. When using accessory tools, raise the Brush Deck

(20)and place the Pump (5) and Vacuum (6) Switches in the ON position.
