Timing Procedures
Setting the Synchronizer
To sew properly, the PFM-4000 Flange Machine synchronizer has only
one
correct
position. This is set by the factory prior to shipping and typically does not require
adjustment. If an adjustment is necessary, refer to
and do the
following:
1
Activate the main sewing pedal to turn the machine one revolution.
2
Remove the synchronizer cover. To do this, grasp the bottom and lift
upward.
3
Loosen the locking screw.
4
Hold the needle positioning disks in place and rotate the handwheel,
ensuring the needles reach their lowest position. Continue holding the disks
and rotating the handwheel until the needle eyes are on an even level with
the needle plate.
5
When the correct setting is achieved, tighten the locking screw securely and
replace the cover.
