Marking the Cutting Line (see figure
A laser beam indicates the cutting line of the
saw blade. This allows for exact positioning of
the workpiece for sawing, without having to
open the retracting blade guard.
– For this, switch the laser beam on with the
switch 37.
– Align the cutting mark on your workpiece
with reference to the right-hand edge of the
laser line.
– Before sawing, check if the cutting line is still
indicated correctly (see "Adjusting the La-
ser", page 65). The laser beam, as an exam-
ple, can misadjust due to vibrations after in-
tensive use.
Position of the Operator (see figure
Do not stand in a line with the saw blade in
front of the machine. Always stand aside of
the saw blade. This protects your body
against possible kickback.
– Keep hands, fingers and arms away from the
rotating saw blade.
– Do not cross your arms when operating the
tool arm.
