I just had to replace the Flow Regulator valve. At the same time I replaced the tracks and brushes. The paperwork, included with the Flow Regulator, actually gave instructions on how to check the Proper Wheel Speed, which is something I never knew about. In following the instructions the speed indicator made 29 revolutions, which falls into the category of "Flow Too Low". It further says that you should adjust the flow to the cleaner using valves at the equipment pad. This is where I'm lost. Any help would be appreciated.
