Adjusting the Depth of Cut (Fig.D)
Your router is equipped with a high-precision depth adjustment
system including a zero reset ring for both the quick adjuster
and the fineadjuster.
Quick Adjustment using the Graduation with
Zero Reset Ring

Triple Depth Adjustment using the Revolver
Depth Stop
The revolver depth stop
12
can be used to set three different
depths. This is particularly useful for deep cuts, performed
insteps.
‑ Place a depth template between the depth stop
13
and the revolver depth stop
12
to adjust the exact
cuttingdepth.
‑ If required, set all threescrews.
Fine Adjustment
When not using a depth template, or if the depth of cut needs
readjustment, it is recommended to use the fine adjuster
17
.
1. Adjust the depth of cut as describedabove.
2. Set the fine adjuster to zero using the ring
24
.
3. Rotate the fine adjuster
17
to the required position: one
turn corresponds to approximately 1mm and 1mark to
0.1mm.
