## Discrepancy

(CAN) AFTER AROUND 100 HOURS THE DRIVE LINK SCORES THE SPACER ON THE ROTATING SCISSORS AND THE SPACER AND THE DRIVE LINK HAVE TO BE CHANGED THE SPACER IS BASICALLY SCRAP BUT THE BUSHINGS ON THE DRIVE LINK CAN BE PRESSED OUT AND CHANGED.  WE THINK THAT THIS IS TOO SHORT A TIME FOR THESE PARTS TO BE SCORING AND TO BE CHANGED.
