6 Manual operation
6.1 Overview
In manual-mode cutting the operator makes all the settings, both before and during cutting.
Measure the outside diameter of the saw blade before installing it. The diameter you enter influences blade
speed of rotation and depth and length of the cut. Installation of the rail, choice of country and system
tolerances influence depth and length of the cut.
Note that the actual depth and length of cut can differ considerably from the values shown or set.

large extent without any further intervention on your part.
