Maximum permissible speeds
valid for relevant genuine Wohlhaupter
accessories
When using the serrated tool body, serrat-
ed slides and insert holder, the tool slider
must first be set to 0 on the scale (center).
The required diameter can then be set
using the slot in the insert holder.
The tool adjustment is then used to finalize
the adjustment procedure. Slider displace-
ment should be kept to a minimum.
Any deviation to this procedure means
that the quoted permissible speeds are not
valid.
