The jaw change key is locked so long as the chuck jaws have not
been moved into the functional area! The functional area means
that the base jaw is engaged by the serration of the wedge bar.
CAUTION
The jaw-change bolt (item 6) may only be turned when the
chuck is in open position.
Risk of damage to the chuck.
CAUTION
The chuck piston (item 3) must not be moved as long as the jaw
change key (item 90) is located in one of the jaw-change bolts
(item 8) for the chuck.
Risk of damage to the chuck.
Base jaw position
Marking lines for jaw positioning are milled into the face side of
the chuck. A single marking line is milled into the jaws. This line
must be exactly above a marking line on the face side of the chuck
when the jaws are changed or shifted.
It is vital that this jaw position is adhered to so that all teeth are
engaged for the force transmission from the wedge bars to the
base jaws or top jaws.
