(3) When wide material is cut with angle, it will
be fi rmly camped by fi xing a steel board
like Fig. 7 to the vise (B).
3. Moving the stationary vise-jaw (Fig. 8)
The vise opening is set at the maximum of
170 mm when shipped from the factory.
In case an opening of more than 170 mm
is required, move the vise to the position
shown by the chain line after unscrewing
the two bolts. The maximum opening can
be set in two steps 205 mm and 240 mm.
When the cutting material is excessively
wide, the vise can be eff ectively used by
repositioning the stationary side of the
vise-jaws.
4. How to use metallic block (Fig. 9)
When the cut-off wheel has a reduced
outer diameter, insert between the vise (A)
and (B) a metallic block slightly smaller
than the dimension of workpiece being cut
to use the cut-off wheel economically.
