Support the chuck while turning three
camlocks 1/4 turn counter-clockwise with
the chuck key enclosed in the tool box.

surface.

3.

Inspect the camlock studs. Make sure
they have not become cracked or broken
during transit. Clean all parts thoroughly
with solvent. Also clean the spindle and
camlocks.

4.

Cover all chuck jaws and scroll inside the
