FIGURE 27
SCRUB BRUSH REPLACEMENT
1. Raise the scrub brush deck by pressing the “Scrub Brush” Switch on the instrument panel.
2. Press the Brush Latches (A) in to release the scrub brush.
3. Remove old scrub brush.
4. Snap new brush into place.
COVERS AND LATCHES
The covers have been designed to allow access, either by hinge or removal, to all areas of the machine. No maintenance
is required. For lubrication of latches see Lubrication Section.
SOLUTION WARNING LIGHT
The solution warning light will illuminate when the solution tank is empty. This part of the level control system requires no
maintenance. If the system fails to operate, consult the Electrical Troubleshooting Guide.
RECOVERY WARNING LIGHT
The recovery warning will illuminate approximately 5 minutes before loss of vacuum to the recovery tank. This part of
the level control system requires no maintenance, except for daily cleaning of the tank level switch. If the system fails to
operate, consult the Electrical Troubleshooting Guide.
SOLUTION CONTROL (NON-RECYCLING OR STANDARD)
The solution control lever controls the amount of solution applied to the scrubbing brushes. Except for a few drops of oil
applied to the lever pivot every 100 hours, the system should require no major maintenance.
The solution control should shut off completely with the lever in the (rear) “off” position. If complete shut off does not occur,
the control cable should be adjusted.
SOLUTION CONTROL (RECYCLING OR ESP SYSTEM)
In the recycling mode, the solution control lever is also used to activate the detergent pump. If the detergent pump fails
to operate (engine running) when the solution control lever is moved into the low to high range, fi rst check the circuit by
manually activating the switch. If the detergent pump does not operate at this time, a further electrical or mechanical
check is indicated. (See Electrical Troubleshooting Guide or Detergent Pump Troubleshooting).
