Operating The Machine-Sweep Mode - Advance ES4000 Mode D'emploi

A-10 / ENGLISH

OPERATING THE MACHINE-SWEEP MODE

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.
CAUTION!
Sweeping with a dry solution tank could reduce the life of the solution pump that powers the misting system.
FILLING THE SOLUTION TANK
While sweeping the ES4000 uses a misting system which sprays water into the airstream to dampen dust as it is drawn into the recovery tank. It is important that
there be water in the solution tank at all times during sweeping so dust does not escape the system. Refi ll the solution tank before sweeping whenever the batter-
ies have been recharged. Under normal conditions, a full solution tank should be adequate to supply the misting system through an entire battery cycle.
To Sweep...
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 3. 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 extraction, follow the "To Switch to Sweep Mode..." instructions at the end of the "Operating the Machine-Extract Mode" sec-
tion. If the machine was last used in sweep mode simply press the Sweep ON / OFF Switch (D) to activate the sweep system.
5 After turning ON the Sweep System the deck will immediately lower to the fl oor. When the Drive Pedal (10) is engaged in forward or reverse, the solution
pump, brush motors, vacuum motors and the misting chamber valve will turn ON. NOTE: When the Drive Pedal (10) is in neutral, the solution pump, brush
motors and the misting chamber valve turn OFF. After 10 seconds, if the Drive Pedal (10) is not engaged, the vacuum motors 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).
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 quali-
fi 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 Sweep ON / OFF Switch (D). The solution pump and misting chamber valve
will turn OFF immediately. The deck will raise to its upper limit and the brush motors will turn OFF. 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.
To Switch to Extract Mode...
1 See Figure 3. Press the Sweep ON / OFF Switch (D) to turn OFF Sweep Mode.
2 Press Extract ON / OFF Switch (F) to activate Extract Mode.
3 The LCD Display (E) will display screen (E15) and the Horn will beep to indicate that the Recovery Hose (29) needs to be switched to the Wet Pick Up Con-
nection (38).
4 After switching the Recovery Hose (29) to the Wet Pick Up Connection (38) press the Extract ON / OFF Switch (F) to acknowledge the hose change. Press
the Extract ON / OFF Switch (F) again to turn ON Extract Mode
5 Refer to OPERATING THE MACHINE-EXTRACT MODE section for further operating instructions.
