INSTRUCTIONS FOR USEA - ENGLISH
2a Normal Scrub Mode: The scrub pressure will default to Normal. Press the Scrub Pressure Increase Switch (M+) once for Heavy Scrub or twice for Extreme
Scrub mode. The solution ow has settings that coincide with the scrub pressure, it will increase and decrease along with the scrub pressure.
NOTE: The solution ow rate can also be increased or decreased independently of the scrub pressure by pressing the Solution Flow Increase Switch (F+)
or Solution Flow Decrease Switch (F-), observe the Solution Flow Rate Bar Graph (C10). Any subsequent scrub pressure adjustments will reset the solution
ow rate to default.
2b Floor Finish Removal Mode: Ensure there is a red pad attached directly to the xed pad driver and that the maroon SPP pad is not attached to the xed pad
driver. In this mode Floor Finish Removal Mode Indicator (C30) appears. The machine will automatically set all machine parameters for this mode as follows;
• Lowest solution ow
• Highest scrub pressure
• No Detergent
• Drive speed set to 50 ft/min [15.2 M/s]. Floor Finish Removal Speed Indicator (low) (C32) appears
Pressing the Speed Limiter Switch (L) will do the following;
• Lowest solution ow
• Highest scrub pressure
• No Detergent
• Drive speed set to 65 ft/min [19.8 M/s]. Floor Finish Removal Speed Indicator (high) (C33) appears
3 The scrub, solution, vacuum and detergent (with EcoFlex) systems are all automatically enabled and will start when the Drive Pedal (3) is activated. Any
individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
NOTE: When operating the machine in reverse the squeegee automatically raises.
Detergent: See “Detergent System Preparation and Use (EcoFlex) for detailed information regarding adjustment and use.
4 Begin scrubbing 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). Adjust the
machine speed and solution ow when necessary according to the condition of the oor. Push the Timed Solution Off Paddle (O) before entering a turn to
temporarily turn off the solution ow. The Solution Flow Rate Bar Graph (C10) will be replaced by a 5 second countdown timer showing how long the solution
ow will be off. Push paddle again before timer runs out to cancel solution off.
NOTE: While scrubbing the maximum machine speed can be set by pressing the Speed Limiter Switch (L). Adjust the machine to the desired speed using
the Drive Pedal (3) then press the Speed Limiter Switch (N). The operator can now press the pedal all the way forward without increasing the machine speed
thereby reducing operator fatigue. The machine Speed (C5) is shown on the display. The speed limit will be in effect every time you scrub until the speed
limiter switch is pressed again (while scrubbing) to disable the speed limit.
CAUTION!
To avoid damaging the oor, keep the machine moving while the brushes are turning.
5 When scrubbing, check behind the machine occasionally to see that all of the waste water is being picked up. If there is water trailing the machine, you may
be dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.
6 For extremely dirty oors, a one-pass scrubbing operation may not be satisfactory and a “double-scrub” operation may be required. This operation is the
same as a one-pass scrubbing except on the rst pass the squeegee (33) and scrub deck blades (AA) are in the up position see Side Blade - Double Scrub
Position. Press the Vacuum Switch (G) to raise the squeegee.
This allows the cleaning solution to remain on the oor to work longer. The nal pass is made over the same area, with the squeegee and side blades
lowered to pick up the accumulated solution
7 The recovery tank has a Shutoff Float (25). When the tank is full the oat is activated and closes the inlet so no more water can enter the recovery tank.
When the oat is activated the operator may notice a change in the sound of the vacuum motor or will notice machine is no longer picking up water. When
the shutoff oat is activated, the recovery tank must be emptied. The machine will not pick up water with the oat activated but no machine functions will turn
off.
OPERATING THE MACHINE (REV)
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.
To Scrub...
Follow the instructions in “Starting the Machine” section and drive the machine to the start point for cleaning.
1 See Figure 3-2. Press the One-Touch Scrub ON Switch (M) the brushes and squeegee are automatically lowered to the oor. The Floor Finish Removal
Prompt Screen (C28) will appear along with the 5 Second countdown timer (C29).
For Normal Scrub Mode - wait until the 5 second timer expires (do not press One-Touch Scrub ON Switch (M) a second time).
For Floor Finish Removal Mode - Press One-Touch Scrub ON Switch (M) a second time before the 5 second timer expires.
