MOUNTING INSTRUCTIONS FOR ER-COLLETS PER DIN STD 6499 Assembling instructions: Collet groove Insert groove of collet into eccentric ring of the clamping nut at the mark on the bottom of the nut. DIN 69871 Push collet in the direction of the arrow until it clicks in place. Screw nut with collet onto toolholder. We Eccentric ring recommend to tighten the nut with a torque wrench. ISO 60 Disassembling instructions: After the nut is unscrewed from the toolholder, press on the face of the collet while simultaneously pushing sideways on the back of the collet until it disengages MA S 403 BT from the clamping nut. Improper  assembly  can  permanently  destroy  the  concentricity of the collet  and may result in a dama- ged clamping nut. DIN 2080 Note: Only mount nuts with correctly inserted collets! Never place the collet into the holder without first assembling it into the nut. HSK-A Never  clamp  oversize  tool  shanks!  e.g. Insert tool the full length of the collet for best never use a Ø 12–11 mm collet to clamp a results  if  possible.  However,  never  insert  tool  Ø 12.2 mm shank. Instead, use the next size up (in this less  than  2/3  of  the  collet  bore  length.  Improper  VDI example, a ø 13-12 mm collet). tool  insertion  can  permanently  deform  the  collet and will result in poor runout.
