8. REPLACING PARTS Rail front-rear position lock screw ●Replacing the rail assembly The rail assembly of this machine can easily be replaced. Escaper If the loaded screws do not smoothly feed after cleaning or if you intend to use a different screw diameter, replace the rail assembly. - Page 20 ●Replacing the brush If the ends of the brush bristles are worn out so that improperly oriented screws cannot be swept away, please replace the brush. To replace the brush, position it as shown. You can adjust its position by rotating the timing shaft. Remove the brush assembly mounting screws and then the brush assembly.
- Page 21 Adjustments to be made after rail assembly/escaper replacement ① .Adjust the clearance between the rail assembly and escaper. ---> Adjust the rail assembly mounting position (front-rear adjustment). The clearance should be minimized. Fine adjustments are needed particularly when the applied screws have a small diameter. For the adjustment procedure, see page 11.
- Page 22 ③ .Adjust the clearance between the rail lateral surface and escaper screw receiver. --> Adjust the escaper screw receiver mounting position (left-right adjustment). Position the escaper screw receiver so that a clearance of about 0.1 to 0.3 mm is provided between the rail lateral surface and escaper screw receiver.
- Page 23 ⑤ .Adjust the positional relationship between the rail groove and escaper groove. ---> Adjust the rail bracket stopper mounting position (left-right adjustment).
