Working Advice
General Sawing Instructions
For all cuts, it must first be ensured that the
saw blade at no time can come in contact
with the fence, screw clamps or other ma-
chine parts. Remove possibly mounted aux-
iliary stops or adjust them accordingly.
Protect the saw blade against impact and shock.
Do not subject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The work-
piece must always have a straight edge to face
against the fence.
Illuminating the Work Area
(see figure K)
Provide for sufficient lighting of the direct work-
ing area.
– For this, switch on the lighting unit 45 with
the switch 30.
Marking the Cutting Line
(see figure L)
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 29.
– Align the cutting mark on your workpiece
with reference to the right-hand edge of the
laser line.
Note: Before sawing, check if the cutting line is
still indicated correctly (see "Adjusting the La-
ser", page 45). The laser beam, as an example,
can misadjust due to vibrations after intensive
use.
Hand Positioning
(see figure M)
Keep hands, fingers and arms away from the ro-
tating saw blade.
Do not cross your arms when operating the tool
arm.
