BRUSH LIFT SYSTEM
BRUSH LIFT SYSTEM ADJUSTMENTS
The brush lift system has two adjustments that can be made. The first adjustment is the
length of travel of the actuator ram. This controls how far down it will allow the brush deck
to go. The second adjustment is the upper linkage adjustment that controls how high the
brush deck will lift off the floor .
To access the actuator and its linkage the body of the machine must be tipped back. To
do this you must first drain the solution and recovery tanks completely. Then release the
2 soft latches directly above the scrub deck on either side of the machine. Now use the
handle bars to tip the body of the machine backwards carefully until the strap stops it. After
the adjustments have been made, tip up the body, secure the two soft latches and test the
machine.
BRUSH LIFT ACTUATOR
The actuator must be able to extend enough to lower the brush head down so that it can
reach slight dips in the floor. If the head can not do this the actuator may not be extending
enough. The distance the actuator extends is controlled by a limit switch that is housed
internally in the actuator.
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.
