ADJUST FRONT SUPPORT
On machines equipped with a front support, always
use both the support and the stress block. After
clamping the front support, insert the stress block
directly under the table on the inside of the front
support. If the table is set at or near its lowest position,
or if machine is equipped with a universal table, the
stress block will not fit beneath the table and should be
applied to the clamp outside of the support.
The vise may be swiveled by loosening the four
clamping bolts of bottom plate. Tighten bolts securely
before beginning to shape.
