For quick and precise setting of often used mitre angles,
the saw table 17 engages at the detents of the following
standard angles:
Left
0°
45° 30° 22,5° 15°
– Loosen the locking knob 13 in case it is tightened.
– Turn the saw table 17 left or right by the locking knob until
the requested standard mitre angle engages.
Adjusting Bevel Angles (see figure K)
The bevel angle can be set in the range from 0° to 45°.
– Loosen the lock lever 31.
– Tilt the tool arm by the handle 5 until the angle indicator 53
indicates the desired bevel angle.
– Hold the tool arm in this position and retighten the clamp-
ing lever 31.
For quick and precise setting of the standard angles 0°
and 45°, factory-set stop screws (22 and 21) have been pro-
vided for.
– 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

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
To save energy, only switch the power tool on when using it.
Switching On (see figure L)
– For starting operation, pull the On/Off switch 37 in the di-
rection of the handle 5.
Note: For safety reasons, the On/Off switch 37 cannot be
locked; it must remain pressed during the entire operation.
The tool arm can be guided down only after pressing button 4.
– For sawing, button 4 must be pressed in addition to pull-
ing the On/Off switch.
Switching Off
– To switch off the machine, release the On/Off switch 37.

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 machine parts. Remove any mounted
auxiliary stops or adjust them accordingly.
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The workpiece must al-
ways have a straight edge to face against the fence.
Illuminating the Work Area (Power Light) (see figure M)
Provide for sufficient lighting of the direct working area.
– For this, switch on the lighting unit 24 with the switch 28.

Marking the Cutting Line (see figure N)
A laser beam indicates the cutting line of the saw blade. This
allows for exact positioning of the workpiece for sawing, with-
out having to open the retracting blade guard.
Right
– For this, switch the laser beam on with the switch 29.
– Align the cutting mark on your workpiece with reference to
15° 22,5° 30° 45°
Before sawing, check if the cutting line is still indicated cor-
rectly (see "Adjusting the Laser", page 35). The laser beam,
as an example, can misadjust due to vibrations after intensive
use.
Position of the Operator (see figure O)
 Do not stand in a line with the saw blade in front of the
– Keep hands, fingers and arms away from the rotating saw
– Do not cross your arms when operating the tool arm.
Permissible Workpiece Dimensions
Maximum workpiece sizes:
Minimum workpiece sizes (= all workpieces that can be
clamped left or right from the saw blade with the provided
quick-action clamp 49):160 x 40 mm (length x width)
Cutting depth, max. (0°/0°): 70 mm
