WARNING!
Be sure you understand the operator controls and their functions.
While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills. Clean only while
ascending (driving up) the ramp.
To Extract...
Follow the instructions in preparing the machine for use section of this manual. Before cleaning in extraction mode the entire area should be cleaned in Sweep
Mode fi rst.
1 See Figure 4. While seated on the machine, adjust the steering wheel to a comfortable position using the Steering Wheel Tilt Adjust Knob (21). The seat can
be adjusted if necessary by tipping up the seat and using the adjustment knob (2).
2 Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights, reference the Battery Condition Indicator (E7) and Hour Meter (E1)
before proceeding.
3 To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (10) to go forward or the rear of the pedal for
reverse. Vary the pressure on the foot pedal to obtain the desired speed.
4 If the machine was last used for sweeping, follow the "To Switch to Extract Mode..." instructions at the end of the "Operating the Machine-Sweep Mode"
section. If the machine was last used in extract mode simply press the Extract ON / OFF Switch (F), Maintenance Mode Switch (G), Restoration Mode
Switch (H) or the Prespray Mode Switch (I) to activate the extraction system. NOTE: Maintenance Mode (G) is the default setting upon initial startup. The
detergent system is OFF by default. It can be turned ON or OFF at any time by pressing the Detergent ON / OFF Switch (C).
5 If either the Maintenance Mode Switch (G) or the Restoration Mode Switch (H) is selected, the brush deck and vacuum shoes are automatically lowered to
the fl oor. When the Drive Pedal (10) is engaged forward, the solution pump, brush motors, vacuum motors and either the maintenance valve or the restore
valve are activated. NOTE: When the Drive Pedal (10) is in neutral or reverse, the solution pump, brush motors and either maintenance valve or the restore
valve turn OFF. After 10 seconds, if the Drive Pedal (10) is not engaged forward, the vacuum motors turn OFF.
If the Prespray Mode Switch (I) is selected, the brush deck is automatically lowered to the fl oor. When the Drive Pedal (10) is engaged forward, the solution
pump, brush motors and the restore valve are activated. The detergent pump will be activated at a specifi c rate. NOTE: When the Drive Pedal (10) is in
neutral or reverse, the solution pump, brush motors, detergent pump and restore valve turn OFF.
6 Begin cleaning by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Turn the
Solution Switch (B) OFF prior to turns to ensure complete extraction of solution from carpet. Adjust when necessary the machine speed according to the
condition of the carpet.
If there is little or no fl uid entering the recovery tank, the solution tank may be empty. Refi ll the solution tank with water.
7 The recovery tank has an automatic fl oat shut-off (27) to prevent solution from entering the vacuum system when the recovery tank is full. When the fl oat
shut-off is activated, the control system will shut down the scrub, vacuum, solution and detergent systems. The Recovery Tank FULL Indicator (E12) will
display. To clear the display, cycle the Key Switch (A). When the fl oat closes, the recovery tank must be emptied. The machine will not pick up water
with the fl oat closed. NOTE: If the control repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a
qualifi ed service technician refer to the service manual to perform this function.
8 When the operator wants to stop cleaning or the recovery tank is full, press the Extract ON / OFF Switch (F). The solution pump, detergent pump and all
three solution solenoids will turn OFF immediately. The deck will raise to its upper limit and the brush motors will turn OFF. After a 3 second delay the
vacuum shoes will raise to the up position. Once the deck is raised, the vacuum motors will turn OFF after a 10 second delay.
9 Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Drain Hose (28) from its rear storage
area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled fl ow of waste water). Refi ll the solution
tank and continue cleaning.
NOTE: Make sure the Recovery Tank Cover (24) and the Recovery Tank Drain Hose (28) cap are properly seated or the machine will not pick-up water correctly.
When the batteries require recharging the Low Voltage Cutout Indicator (E13) will come on. The brushes, pumps and solenoids will turn OFF and the deck will raise up. Transport the
machine to a service area and recharge the batteries according to the instructions in the Battery section of this manual.
