Scub Sytem - Disc 39Service Manual – SC351
Scrub System, Disc
Functional Description
The disc brush system can be started by the operator.
The disc brush turns counter-clockwise.
The brush system, when turning, cleans/washes the oor surface and assists machine forward movement.
The deck, where brushes suitable for cleaning the particular type of oor are installed, is the main part of the
scrub system. The brush deck is xed and integrated in the machine with a support bracket. The adjusting sys-
tems adjusts the forward speed, while the handwheel on the deck adjusts the machine straight-forward drive.
The brush working pressure is functional to the machine designed balance.
The brush motor (M1) is supplied by vacuum brush motor relay (K1) which is driven by the program selection
knob/rotary switch (SW1) when it is turned to 1, 2 or 3, and the machine start-up enabling push-button (SW2)
is pressed. The circuit is protected by the brush motor fuse (F1).
The system, once activated, uses the solution coming form the solution system, to wash the oor.
To work properly, the brush motor needs the following:
• Program selection knob/rotary switch (SW1) turned to 1, 2 or 3
• Machine start-up enabling push-button (SW2) pressed
• Charged batteries (the red LED must not be ashing).
• Battery charger is completing path to battery negative for B2
When necessary, to use the squeegee in the opposite direction, pry on the handlebar and slightly lift the deck
while the brush is turning. The rubber pads mounted into the deck allow the mechanical rotation by creating
friction on the rotating brush. When the deck is turned by 180° start to scrub/dry by drawing the machine.
To resume working in the normal forward direction, push the machine forward until the brush deck returns
to the original position.
