FUNCTIONAL DESCRIPTION OF CONTROLS:

Upper (recovery) Tank (1) - Waste water recovered from carpet is deposited here inside of a bladder (34). Area outside of waste water bladder (34) is utilized for extra clean solution capacity. The batteries and Vac Motor Filters (32) can be accessed by opening this tank to the side.

Recovery Tank Dome Lid (2) - Point of entry for waste water into bladder. Also houses Automatic Float Shut-Off (33) which shuts off vacuum port to vac motors when bladder is full. Remove this lid to rinse out the waste water bladder or to fill the solution tank.

Battery Fuel Gauge (3) - Shows current state of charge of batteries. A double-flashing light indicates low batteries, charge immediately. NOTE: When the battery fuel gauge shows double-flashing lights, all systems shut down except the wheel drive system.

Master Key Switch (4) - Main power switch.

Pump Switch (5) - This button is used to select the mode of operation for the solution system. There are 3 modes of operation for this system. The modes are AUTO / OFF / ON. Following is a description of each mode.

AUTO MODE: In this mode the solution flow will be turned ON whenever the brush is lowered and the machine is moving forward. The solution flow will be turned off when the machine is not moving, moving in reverse or the brush is raised.

OFF MODE: In this mode the solution flow is turned off.

ON MODE: This mode is for accessory use. The pump is ON at all times as long as the Master Key Switch (4) is ON.

Vacuum Switch (6) - This button is used to select the mode of operation for the vacuum system. There are 3 modes of operation for this system. These modes are AUTO / OFF / ON. Following is a description of each mode.

AUTO MODE: In this mode the vacuum will be turned ON whenever the brush is lowered and the Master Key Switch (4) is ON. While in this mode the vacuum will remain on for 10 seconds after the brush is raised.

OFF MODE: In this mode the vacuum is off.

ON MODE: This mode is for accessory use. The vacuum is ON at all times as long as the Master Key Switch (4) is ON.

Hourmeter (7) - Displays number of hours machine has been used. NOTE: The hourmeter only runs when the vac motors are running.

Brush Pressure Indicator (8) - This meter should be reading 8-15 amps (green zone), readings outside this range indicate the need for brush height adjustment. Speed Control Knob (9) - Turn this knob clockwise to increase maximum speed range and counter-clockwise to decrease maximum speed range.

Operator Control Handle (10) - Operator holds onto this handle to maneuver the machine.

Drive Paddle (11) - The operator can make the machine go forward by pushing forward on it, or reverse by pulling backward on it. The speed is variable depending on how far forward or backward the paddle is moved. The brush and pump will operate when the brush deck is in the “DOWN” position and the drive paddle is engaged in either direction, both will stop 1 second after the drive paddle is released. NOTE: The pump does not run when the drive paddle is in the reverse position.

Brush Deck Lift Lever (12) - This lever is used to raise or lower the brush deck. Both pump and vacuum turn ON when the brush deck is lowered and turn OFF when it is raised if their switches are in the AUTO position. NOTE: Machine must be moving forward to activate pump, forward or reverse to activate brush. Vacuum system shuts off 10 seconds after raising the brush deck.

Upper Tank Latch (13) - This latch is used to secure the Upper Tank (1) to the machine to prevent the tank from opening while operating the machine since the Operator Control Handle (10) is mounted to the upper tank.

Accessory Port (14) - This is used to connect external accessories.

Circuit Breakers (15)

6 Amp-Control Circuit - Provides overload protection. If it trips, it will pop out. To reset, wait one minute and press the button back in. If any breaker trips repeatedly, have the machine serviced.

40 Amp-Vac Motors - Provides overload protection to machine’s vacuum motors. If it trips, it will pop out. To reset, wait one minute and press the button back in. If any breaker trips repeatedly, have the machine serviced.

20 Amp-Brush Motor - Provides overload protection to machine’s brush motor. If it trips, it will pop out. To reset, wait one minute and press the button back in. If any breaker trips repeatedly, have the machine serviced.

20 Amp-Drive Motor - Provides overload protection to machine’s wheel drive motor. If it trips, it will pop out. To reset, wait one minute and press the button back in. If any breaker trips repeatedly, have the machine serviced.

Battery Charger Connector (16) - Plug battery charger into this port to charge batteries.

Recovery Tank Drain Hose (17) - Used to empty the recovery tank. NOTE: Hold the end of the hose above the water level in the tank to avoid sudden, uncon- trolled flow of waste water when removing plug.

Pick-Up Tool (18) - Removes excess solution from carpet after scrubbing.

Brush Height Adjustment Knob (19) - Used to adjust the height of the brush deck. Turn clockwise to raise the brush deck and counter-clockwise to lower the brush deck. NOTE: Use this adjustment knob in conjunction with the Brush Pressure Indicator (8).

Brush Deck (20) - Contains brush drive motor and brush.

Solution Drain Hose/Level Indicator (21) - Used to empty the solution tank and show current level of solution in tank, graduations are marked on the side of the machine next to the hose.

Solution Fill Cap (22) - The solution tank can be filled at this location or through the front opening at the top of the Upper Tank after removing the Recovery Tank Dome Lid.

Vacuum Hose (23) - This hose connects to the vac motor assembly in order to create a vacuum inside the waste water bladder.

Recovery Hose (24) - This hose connects between the Pick-Up Tools (18) and the Recovery Tank Dome Lid (2) to bring waste water into the bladder.

Nozzle Selector Knob (25) - Use this knob to select either Maintenance Mode or Restoration Mode. NOTE: The Speed Control Knob (9) has two corresponding settings.

Maintenance Mode: Lower solution flow, higher travel speed. Recommended for frequent surface cleaning.

Restoration Mode: Higher solution flow, lower travel speed. Recommended for less frequent deep cleaning. Stabilizer Caster (26) - This caster provides stability to the unit when opening the Upper (recovery) Tank (1).

Rear Caster (27) - These two casters along with the main drive wheel bear the weight of the machine and allow easy maneuvering around corners. Lower (solution) Tank Flush-Out Cap (28) - This cap allows access to the Lower (solution) Tank for the purpose of flushing with clean water. Brush Access Door (29) - The power brush can be removed or installed via this door.

Brush Access Door Latch (30) - Unsnap this latch to allow access to the power brush.

Deck Release Knob (31) - Pull this knob out and slide Brush Deck out to the right until it latches in place. This allows cleaning under shelves, railings, etc. Vac Motor Filters (32) - Intake filters for vacuum motor assembly. Refer to the maintenance chart for maintenance intervals.

Automatic Float Shut-Off (33) - The float shut-off blocks the vacuum port when the Waste Water Bladder (34) is full. You can tell when the float closes by the sudden change in sound of the vacuum motors. When the float closes, the recovery tank must be emptied. The machine will not pickup water with the float closed. Waste Water Bladder (34) - Contains waste water as it is recovered from carpet. Total capacity of 30 gallons (113.5 Liters).

Roller Bumper (35) - This is a 3 position slide-out bumper to aid in machine maneuvering along walls.

InLine Pump Filter (36) - This filter removes debris from the solution prior to flowing through the pump. Drain solution prior to cleaning this filter. Lower (solution) Tank (37) - This tank in combination with the upper tank brings total solution capacity to 40 gallons (151.4 Liters).
