  Reduced performance in your National Flooring Equipment Other could stem from several causes. The blast wheel or control cage might be worn, requiring replacement. Check and adjust the belt tension. Ensure the valve closes properly; if not, close the valve, stop the motor, and readjust the valve. Make sure the motor reaches maximum speed before opening the valve to avoid admitting too much abrasive. Reduce the feed motion speed if it's too fast. Lastly, verify the motor's rotation direction; if incorrect, turn off control power, wait for the motor to stop, then switch the FWD/REV switch to the opposite position.

  Your National Flooring Equipment Other may be dumping abrasive due to several reasons. One reason may be poor abrasive quality, so use quality abrasives. Also, worn blast wheel or seals, replace blast wheel or adjust/replace seals. The control cage may not be correctly adjusted, align notches to the 9:00 and 11:00 position. The magnets may be at the wrong elevation, adjust elevation of magnets. Too much dust or sand in system, check filter. The valve may be opening too far and allowing too much shot into the blast wheel, causing the Amp draw to be over 25 Amps, reset the valve opening so the maximum Amp draw isn’t higher than 20 Amps on the meter. The blast valve could be stuck open, inspect and remove debris.
