7. Turn the “HEAD BRAKE” switch OFF (RELEASE).
8. Rotate the handwheel to set the cycle timer to 233°.
9. Turn the “HEAD BRAKE” switch ON (LOCK).
10. Combine thickness gauges properly and check that the gap
between the head and anvil is within the range of PCB
thickness + 0.25.
=REMARKS=
Check the clearance at two consecutive cycles because
a 2-cycle cam is incorporated.
11. If there is some clearance or if the PCB is being pressed down, loosen the nut bolt and rotate the slide
block to adjust the insertion guide height. (Insert an Allen wrench in the hole of the slide block and rotate it
to make adjustment.)
12. When adjustment is completed, tighten the nut bolt.
