Carefully disassemble the jaw chuck. To do this, loosen the cam-locks
by turning them clockwise (approx. one third of a turn) using the
clamping key supplied and carefully remove the jaw chuck.
Check the cam-lock studs. Ensure that they are not damaged or
broken during transport. Clean all parts thoroughly. Also clean the
spindle and the cam-locks. Lightly oil the spindle, cam-locks, camlock
studs and chuck body with a suitable machine oil.
Then lift the jaw chuck up to the spindle nose and press on the
spindle. Tighten the cam-lock studs by turning the cam-locks
counterclockwise. After tightening, the cam-lock line should be
located between the two V-marks - see illustration on the left.
If a cam is not within this mark, remove the chuck or face plate and
adjust the height of the cam-lock studs - see the following illustration.
The cam-lock stud is correctly adjusted when the mark (C) carved into
the stud is flush with the back of the chuck.
If the cam-lock line is outside the V markings, adjust the height of the
relevant cam-lock stud.
To do this, first loosen the retaining screw (B), adjust the cam-lock stud
by turning it in/out one full turn at a time and then tighten the
retaining screw firmly again.
If the chuck (clamping device) is correctly fastened, a reference mark
should be attached to the spindle and clamping device so that the
clamping device can always be released and remounted in the same
position to ensure optimum concentricity.
Do not change chucks or face plates between lathes without checking
for correct cam-locking.
WARNING
1.
Clean the inner taper of the spindle holder.
2. Clean the morse taper and the taper of the centering tip.
3. Press the centring tip with the morse taper into the inner taper
of the turning spindle holder.
