For quick and precise setting of often used mi-
tre angles, detents 14 are provided on the saw
table:
Left Right
0°
15°; 22,5°; 15°; 22,5°;
30°; 45° 30°; 45°
– Loosen the locking knob 11 in case it is tight-
ened.
– Pull lever 12 and rotate the saw table 8 left
or right to the requested detent.
– Release the lever again. The lever must be
felt to engage in the detent.
Adjusting Vertical Bevel Angles
(see figure I)
The vertical bevel angle can be set in the range
from 0° to 45°.
– Loosen the clamping lever 21.
– Tilt the tool arm by the handle 5 until the an-
gle indicator 20 indicates the desired bevel
angle.
– Hold the tool arm in this position and retight-
en the clamping handle 21.
For quick and precise setting of the standard
angles 0° und 45°, end stops are provided on
the housing.
– For this, tilt the tool arm by the handle 5 to
the stop toward the right (0°) or to the stop
toward the left (45°).

Starting Operation

Switching On
– For starting operation, pull the On/Off
switch 4 in the direction of the handle 5.
Note: For safety reasons, the On/Off switch 4
cannot be locked; it must remain pressed during
the entire operation.
The tool arm can be guided down only after
pushing the locking lever 35.
– For sawing, the locking lever 35 must be
pushed in addition to pressing the On/Off
switch. (see figure J)

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.
