c) Reversing the
BAV jaws
• Turn knurled ring
anti-clockwise and
remove jaws.
• Reverse jaws (bolt
heads facing out-
ward) and reinstall
as follows:
• Jaw 3 in slot 1,
• jaw 2 in slot 2,
• jaw 1 in slot 3
while
• turning the knurled
ring clockwise
again.
d) To speed up
the rotation of the
knurled ring, insert
a 6 mm round bar
or drift punch into
the hole provided for
that purpose in the
face of the knurled
ring and use it as a
crank.
Maintenance
Periodically apply a
small amount of oil
to the scroll thread,
removing the jaws.
Always insert the
bolt heads of the
setting jaws into the
counterbores of the
soft jaws as far as
they will go.
To avoid damage,
do not exceed the
suspension ranges.
Remarks
a) Turning the
steps or outside
diameters of soft
solid jaws
The BAV jaw cutting
attachment may also
be used for turning
solid jaws. In that
case, the user should
drill one hole each, in
the front face of the
jaws. The position of
these holes depends
on the desired step
turning range. (The
position of the hole
to be drilled can
be marked with a
scriber). b) Grinding harde-
ned jaws
Similarly, the BAV
cutting attachment
may be used for re-
grinding jaw steps. In
that case, excessive
dirt on the setting
jaw serrations must
be avoided. (Remove
dust with a brush
from time to time).
c) Working range
At least 2 cutting
attachments are
required to cover the
complete working
range (chucking
range) of the chuck
and jaws.
