The values specified are typical but without im‐
plied guarantee.
In some materials, flame, plasma and laser cut‐
ting techniques can lead to hardening of the
edges of the workpiece being machined. This can
result in significant deviations from the specified
reference values.

The bevel height (a) is set by adjusting the position
of the guide plate. The height setting can be read
from the fixed main scale
collar

Release clamping screw
Rotate the guide‐plate unit until the required
bevel height has been set as shown by the fixed
main scale in combination with the vernier

scale on the collar .

Re‐tighten clamping screw
Once the bevel height has been set, a bevel should
be milled on a test sample to check whether fur‐
ther height adjustments are required. These may
be necessary because the precision of the scale is
approximately ± 1 mm, depending on the type of
milling head fitted.
