SOLUTION FLOW CONTROL VALVE REMOVAL

1 Drain the solution tank and also remove the squeegee tool from the machine (this allows the needed room to work on the valve).
2 See Figure 4. Loosen the Hose Clamp (D) and pull the Hose (E) off the valve elbow fitting (F).
3 Remove the Screw (M) that holds together both the water valve shaft arm and the solution valve arm.
4 Separate the control arms and work the shaft up and off the valve to allow the clearance for removal.
5 Turn the valve out of the solution tank connection and remove it from the machine. Note it is not necessary to remove the tank drain hose, just compress
the hose to allow needed clearance to remove the valve.
