At the lower spindle speeds and at
smaller tool diameters an increased
risk of workpiece kickback exists.
The maximum permissible speed
-1
(rpm, /min, min ) marked on each
tool may never be exceeded.
Router bits may only be operated in
the highest spindle speed (10000
rpm).
The speed is set by changing the V-
belt location on the pulleys (Fig 7).

Speed range:
4000, 6000, 8000, 10000 RPM
The chosen spindle speed can be
seen on the viewing window.
