Adjusting the High-Speed Spring System
The feature that separates the PFM-4000 Flange Machine from all others is the
high-speed spring system. This unique spring system design allows the flange
machine to operate at 4000 rpm with minimal vibration. Ensure the presser foot
and top feed settings are correct before adjusting the spring system. Instructions
for those settings begin on page 52. To adjust the high-speed spring system, refer
to

2
Manually rotate the handwheel until the presser foot touches the needle
plate.
3
Loosen the jam nut.
4
Turn the cylinder shaft clockwise until the roller of the link touches the
presser button.
5
Tighten the jam nut to maintain the proper setting achieved at Step 4.
