MACHINE OPERATION
When the vehicle motion is stopped the brushes
(including the side brush, if installed) and solution fl ow will
automatically shut off . When the vehicle begins to move
the scrub brushes and the solution automatically resume
operation.
When the scrubber is driven in reverse the squeegee
automatically raises from the fl oor.
MAIN BRUSH SCRUB PRESSURE KNOB
The Main Brush Scrub Pressure is selected
using a rotary control knob which provides three
pressure settings: Light = 200 lb (90,7 kg);
Medium = 300 lb (136,1 kg); and Heavy = 400 lb
(181,4 kg). Upon start-up the system responds
to the last pressure setting used. The scrubbing
pressure can be changed while the scrubber is in
operation.
SIDE BRUSH SCRUB PRESSURE
The optional Side Brush Scrub Pressure is variable and
automatically changes to balance with the setting of the main
brush pressure.
SOLUTION CONTROL KNOB
The solution fl ow is selected using a three
position rotary knob which provides: Off , Low,
and High solution fl ow.
The
Low fl ow setting
is for normal scrubbing,
smooth fl oors, and light dirt. The fl ow rate is .88
gal/hr (3,33 L/hr), providing 2.0 hours of scrub time.
The
High fl ow setting
is for rough fl oors and heavy
or compacted dirt. The high fl ow rate is 1.50 gal/hr
(5,67 L/hr), providing 1.2 hours of scrub time.
Note
: The solution fl ow starts and stops automatically when
the solution fl ow switch is set in the low or high position.
The fl ow can be manually shut off when suffi cient solution is
already on the fl oor.
The side brush solution fl ow starts and stops automatically.
The side brush has only one fl ow rate. The fl ow rate is
factory set, but can be adjusted by turning the slotted screw
on the solution solenoid valve located below the frame just
behind the side scrub brush.
