Medium speed (0.45 sec):
SC30, ON: 270 q, OFF: 312q
High speed (0.36 sec):
SC31, ON: 265 q, OFF: 312q

Adjusting insertion chuck height
(When underfeed occurs)
1. Loosen bolt A (x 2) until there is play in
the insertion head upper end stopper.
2. Turn the hand wheel until the cam shaft is
at the 0 q position on the digital sequence
timer, insert a gap gauge the same size
as the discrepancy when the insertion
chuck is in the chucking position,
between the upper stopper and the
insertion head. Without removing the
gauge, tighten bolts A (x 2) until fixing the
stopper in place.
=CHECK=
Fix the upper stopper such that the gap
gauge is flush against both the upper
end stopper and insertion head.
3. Remove the gap gauge and turn the hand
wheel until the cam shaft is at the 90q
position on the digital sequence timer.
4. Loosen bolts B (x 5) from the rear side of
the machine until there is some play in
the insertion head vertical lever.
