BRUSH LIFT SYSTEM
If the brush head lifts too high when it is in the full-raised position it may not have enough
travel to extend low enough to reach into recesses in the floor. If the machine exhibits this
condition, lower the overall brush height by backing out the screw on the upper suspension
arm.
LINKAGE ADJUSTMENT
If the brush deck is out of adjustment and it can not be remedied with the limit switch ad-
justment there is a provision for adjusting the linkage. At the top of the brush deck lift
linkage there is a bolt that is secured with a jamb nut. This bolt is used to increase or de-
crease the raised height of the deck. If too much adjustment is made to this screw to lift the
head, the deck may not have enough travel to reach and put pressure on the ground.
ACTUATOR ADJUSTMENT
To access the limit switch in the actuator remove the black rubber strip on the face of it.
Loosen the set screw just enough for the switch to slide. To increase the travel of the deck
slide the limit switch down toward the floor. To increase the travel slide the limit switch
up towards the top of the machine. When the switch is repositioned gently tighten the set
screw and replace the black rubber strip.
Remove this
black rubber
strip to gain
access to the
limit switch.
