Solution Filter Cleaning

4. Unscrew the solution filter cover
5. Remove and clean the screen.
6. Re-assemble in the reverse order. Make sure the gasket is seated properly in the filter cover.

Resetting the Solution Flow Adjustment Knob

NOTE: The solution valve has approximately (5) full 360 degree turns of adjustment from OFF to Maximum.
The solution flow adjustment knob allows only about (1) full turn of adjustment. The factory setting is at the
mid-range of the solution valve. Some customers want more solution flow (i.e. for unfinished concrete floors),
while some customers may want less solution flow (i.e. for VCT)
1. Use a pliers to grip the brass knob stop.
2. Use a #2 phillips screwdriver to remove the screw that holds the pin. (Directly under the pin)
3. Turn the solution adjustment flow knob to get the desired amount of solution flow. Clockwise for LESS
flow, Counter-clockwise for MORE solution flow. NOTE: Do not adjust the knob too far. If you adjust
the knob to the Minimum or Maximum position of the solution valve, it can get stuck.
4. Replace the brass knob stop.
