Adjusting the bevel width and height
The bevel height can be adjusted
using the support plate and is
metered by means of the marker
on the graduated collar.
1 = Support plate.
2 = Knurled nut.
3 = Adjusting collar.
4 = Scale.
5 = upper limitation stone
a) Loosen knurled screw (2).
b) Turn support plate (1) until desired bevel height is achieved on graduated collar. The line markings on
the scale indicate the approximate bevel height in millimetres (one marking line is approx. 1mm). Use the
markings on the adjusting collar for fine adjustment. The distance from one marking line to the next
corresponds to approx. 0.1mm of chamfer height.
c) Tighten knurled screw (2).
d) The upper limitation stone (5) limited the bevel width
The bottom mark on the scale corresponds to a bevel height of approx. 1mm. It is
recommended to establish the exact chamfer height using a test job.
Graduated Collar:
On assembly, the device is adjusted to zero position. Zero position means a bevel height of 0.
