Belt Tracking Sensor
The U-shaped bracket includes an air pressure sensor that senses when the belt is displaced into this area. The sanding belt MUST be positioned into the U-shaped bracket when it’s threaded onto the machine - failure to position the belt Into the U-shaped bracket will destroy the belt when first powered on. This air pressure sensor then activates the tracking system which pivots the upper roller sending the belt in the opposite direction. If the air pressure sensor on this mechanism is too low, it will not sense the belt moving into this area, and the result will be the belt continues sideways into the U-shaped bracket tearing the belt.
