• Offset the base jaws so that they do not project over the outer
edge of the chuck.
• The entire chuck has to be rotated on the draw tube (rod).
• Alternately tighten the mounting screws supplied to fix the
chuck to the spindle nose.
• Check radial and axial runout at the checking edge.
• Check the function and the size of the operating force.
• Move the cylinder into the front position. Unlock the wedge
bars with the jaw change key supplied and insert or offset the
base jaws into the chuck's jaw guidance as shown on markings
1, 2 or 3.
• Check that the base jaw and jaw stroke are easy to move.

• Lift the chuck to in front of the spindle lug using an eye bolt
flush to the center of the spindle.
• Screw the rotating center sleeve (item 18) onto the draw tube
using the enclosed assembly tool as far as this will go.
• Alternately tighten the mounting screws supplied to fix the
chuck to the spindle nose.
• Check radial and axial runout at the checking edge.
• Check the function and the size of the operating force.
• Insert and fasten the protection sleeve (item 4) in the chuck
body with the screws (item 43).
