Adjusting guide rail position
1. Set a PC board and tighten the hexagon headed
bolts (x 4) enough to hold the board in place.
2. While checking with a gap gauge, move the
guide rail until the distance between the side of
the PC board and the side of the guide rail is
0.3 mm in all places.
3. After making adjustments, retighten the hexagon
headed bolts (x 2) and bolts A (x 2) so as to fix
the guide rail in place. Slide the PC board along
the rails checking to make sure it slides without
catching or incurring other irregularity.
