Drop the employed screws into the rail groove. Slide the screws to the passage
window section and check or adjust the passage plate height. Check that the 
clearance between the passage window upper end and the screw heads is not 
greater than about 0.5 mm and that the screws can pass the passage window.
If the above requirements are not met, repeat above adjustment
procedures as needed. 
After adjustment is completed, tighten the passage plate retaining screw. If the  
screw applied has a relatively short shank, fine adjustments may be needed. For 
screws having a relatively long shank, however, coarse adjustments will suffice.

Drop about 10 applied screws into the rail groove.
Tilt this machine or operate it so that the screws are delivered to the rail assembly 
stopper.
If the shutter is closed or there is no clearance between the holding plate
(screw guide 1) and screw heads, the screws will not be able to move. The 
screws can move when the shutter is open with an adequate clearance provided 
between the holding plate (screw guide 1) and screw heads.
When the clearance is 0 to 1 mm, the holding plate (screw guide 1) height needs 
no further adjustment.
NOTE: If the rail stopper captures a screw and brings the vibration to a stop 
            immediately, adjust the timer setting control on the rear side of the unit.
