4. Using the collet wrench, turn the collet clockwise until it contacts the piston taper.
5. Tighten the collet locking screw. Do not overtighten.
6. To close the collet closer, insert a workpiece in the collet, and connect the supply to the control valve.
WARNING:
Do not close the closer without the workpiece in the collet.
7. Adjust your supply pressure to a level that assures effective workholding only. Continuously operating the closer at
maximum pressure will decrease the service life of the seals and collet.
WARNING: Pressure to this closer above 250 psi air or 207 psi hydraulic (7 bar air, 83 bar hydrualic)
may overstress the 5C collet.
8. To open the collet, actuate the valve.
Maintenance
If, over a period of time, you experience a decrease in clamping force even though pneumatic or hydraulic pressure remains
unchanged, remove the collet block from service, disassemble, and replace any damaged or worn o-rings.
