DIN 6499 – ISO 15488 Assembly Instructions
The ER Collet must first be inserted into the ER Nut before it can be put onto the Collet Chuck. Never insert the collet into the chuck and then attempt to tighten the nut over – this will damage the assembly. Make note of the high point of the eccentric ring (indicated by a “E” mark on the face of the Nut) and insert the collet such that the groove fits over the ring. Push the collect into position (you will hear a click) as per the illustration on the left. Now it is safe to thread the Nut and Collet assembly into the collet chuck. Disassembly Instructions
Remove the Nut and Collet assembly from the collet chuck and follow the instructions in reverse of the assembly steps. Press on the face of the collet (see red arrows) and push the collet down until the collet removes from the nut.
