ADJUSTING THE SCRUB DECK (See Figure 37)
Adjust the center of the rod end to 3.5” from the frame.
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.
SOLUTION LOW WARNING LIGHT
The solution low warning light will illuminate when the solution tank is low.  This part of the level control system
requires no maintenance.  If the system fails to operate, consult the Electrical Troubleshooting Guide.
RECOVERY HIGH WARNING LIGHT
The recovery high 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 knob controls the amount of solution applied to the scrubbing brushes.
The solution control should shut off completely with the knob in the  “off” position.  If complete shut off does not
occur, the control valve 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, first
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 required (see Electrical Troubleshooting Guide or Detergent Pump
Troubleshooting).
