the cut allowed.
11. Define whether an overcut should be made at the start of the cut.
◁
When overcutting, the cut is extended so that the set length of cut is also reached, as far as possible,
at the reverse side of the wall being cut through.

If the starting point of the cut is in the direction of the plus sign, as viewed from the saw head center
mark, set the distance as a positive value. If the opposite is the case, set the distance as a negative
value. When you define an obstacle, the plausibility of your entry defining the distance from the saw
head is checked. If the value you enter is too low, it is corrected to the required minimum distance.
◁
The corrected value is shown on the screen if a correction is made.
14. Use <<OK>> to confirm your settings.
