MOUNTING INSTRUCTIONS FOR ER-COLLETS PER DIN STD 6499 Assembling instructions: DIN 69871 Insert groove of collet into eccentric ring of the Collet groove clamping nut at the mark on the bottom of the nut. Push collet in the direction of the arrow until it clicks in place. Screw nut with collet onto toolholder. We recommend to tighten the nut with a torque wrench. Eccentric ring ISO 60 Disassembling instructions: After the nut is unscrewed from the toolholder, press MAS 403 BT on the face of the collet while simultaneously pushing sideways on the back of the collet until it disengages 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.
