The torque for the set screw fastening is 0.686 N.m (7 kgf.cm).
If the set screw is fastened with too much torque, the screw
section might be deformed.
The caution applies to the other screw removals and attachments.
(a) The attachment position to be changed is marked on the pitch
selecting section.
(b) Tape feeders such as TF-2411, TF-3211 and TF-4411 are for two
or more feedings, so attach the tape feed link at 12 mm for the 24
mm pitch or at 16 mm for the 32 mm pitch.
