If the holding plate (screw guide1) height needs to be adjusted, pro
-
ceed as directed below.
Tilt this machine or operate it so that the screws are delivered to the
rail assembly stopper. If there is no clearance between the holding
plate (screw guide1) and screw heads, the screws cannot move.
The screws can move while the shutter is open with an adequate
clearance provided between the holding plate (screw guide 1) and
screw heads.
If the screws do not move to the escaper section, loosen the bit guide
assembly retaining screw, and rotate the bit guide assembly up-down
adjustment screw counterclockwise with the accessory Allen wrench
to move the holding plate (screw guide 1) upward. Adjust the holding
plate (screw guide 1) height by rotating the bit guide assembly height
adjustment screw to provide a clearance of 0 to 1 mm between the
holding plate (screw guide 1) and the head of the screws.
When performing the above adjustment procedure, ensure that the
gap between the holding plate (screw guide 1) and rail is uniform.
Please make sure that the gaps between the holding plate and the
rail are the same on the rear end and the front end. After completion
of adjustment, be sure to tighten the bit guide assembly retaining
screw.
If the employed screw has a relatively short shank, fine djustments
are needed. For screws having a relatively long shank, however,
coarse adjustments will suffice.
4-5. Checking and Adjusting the Rail Assembly
Check the position of the stopper and sensor.
- Ensure that the rail is fixed so that “A” portion of the stopper is 0mm
to 0.5mm ahead of the sensor optical axis.
- If adjustment is necessary, adjust it front and rear by loosening the
rail front-rear position lock screw
