• Lift the locking pin B upwards from the groove and turn it for 90° in any direction. This
unlocks the locking device.
• Turn the knob C counterclockwise, until the max. clamping range is reached.
• Turn the locking pin B back for 90° until it engages in the groove again.
• Insert the milling jar and press lightly into the centering point A.
• Gently turn the knob C clockwise, until the milling jar just fits, free of play, in the
holder. Then continue to turn the knob clockwise for 1 - 2 clicks, while at the same
time the locking pin B is raised and lowered.
The engaged locking pin prevents automatic opening of the milling jar holder.
If the locking pin B cannot be pulled upwards to release it, unlocking should not be forced
with any tool. Otherwise the locking pin can break off. Briefly retighten the knob C in the
clockwise direction and the locking pin can then move freely again.
To remove the milling jar, lift the locking pin B, turn it for 90° and turn the knob C in the
direction to loosen it.
