Scrub System
79
Service Manual – SC1500
Brush Motor Contactor
The
Brush Motor Contactor (K2)
controls the
power to the Brush/Pad Motor.
Deck Actuator Assembly
The
Deck Actuator Assembly
uses an electric
Motor
to run a lead screw
that extends and retracts the
Tube
and attached
Plunger
. The
Plunger
is
connected to the Scrub Deck to raise and lower the Scrub Deck to any of
four different positions:
• The fully-retracted (up) position is the Scrub Deck transport position
and is used when the Scrub and Recovery Systems are not active.
• Scrub Deck position 1 is the vacuum-only position. In this position the
Deck Actuator lowers the Scrub Deck just far enough for the squeegee
to contact the floor to pick up wastewater with the Scrub, Solution and
Detergent Systems off.
• Scrub Deck position 2 is the standard scrub pressure position.
• The fully-extended (down) position is the extra scrub pressure position.
