Top of page MAINTENANCE Clean the sealing section regularly with compressed air to remove any dust and particles. Lubricate the die (position 18), punch (position 36) and punch ZL (position 31) daily with a thin grade of oil. This will reduce friction and extend the life of the tool as well as the parts. Spray the entire tool daily with a rust preventative, this will prevent any rust formation. Top of page ADJUSTMENTS TO ADJUST SEALING DEPTH Loosen nut (position 42), adjust hexagon socket set screw (position 59) with a hexagon key, turn counter clockwise to increase sealing depth, or turn clockwise to decrease sealing depth, retighten nut. TO ADJUST CLEARANCE BETWEEN THE FEEDWHEEL (POSITION 5) AND GRIPPER (POSITION 37) The clearance between the feedwheel and the gripper should be .020" (.51 mm). If the clearance is more or less than this, it must be adjusted.
