Start-up Pump Tuning Procedure
1. Connect the tool’s solution hose to the quick disconnect.
2. Turn the ignition switch to the “ON” position.
You do not need to start the unit since vacuum is not needed for this procedure.
3. Select “CARPET/UPH.” on the Solution Control switch.
4. With the pump still on, disconnect the solution hose from the Flex unit.
The pump should run for about 3 to 5 seconds and then switch o.
5. Leave the hose disconnected.
