Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.
Switching on (see figure K)
– To start the tool, press the on/off switch (31) and keep it
pressed.
Note: For safety reasons, the on/off switch (31) cannot be
locked; it must remain pressed during the entire operation.
Only by pressing the locking lever (13) can the tool arm be
guided downwards.
– For sawing, you must therefore press the locking
lever (13) in addition to pressing the On/Off switch (31).
Switching off
– To switch off, release the on/off switch (31).
Starting current limitation
The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the starting current limit-
ation has failed. The power tool must be sent to the after-
sales service without delay. For addresses, see: After-sales
service and advice on using products.

Practical advice

General sawing instructions
Always tighten the locking knob (21) and the clamp-
u
ing lever (7) firmly before sawing. Otherwise the saw
blade can become wedged in the workpiece.
For all cuts, it must first be ensured that the saw blade
u
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.
Only saw materials which are permitted within the scope of
the intended use.
Do not saw warped/bent workpieces. The workpiece must
always have a straight edge to face against the fence.
The free end of long and heavy workpieces must have some-
thing placed underneath it or be supported.
Make sure that the retracting blade guard operates properly
and that it can move freely. The retracting blade guard must
open when the tool arm is guided downwards. When the tool
arm is guided upwards, the retracting blade guard must
close again over the saw blade and lock in the uppermost po-
sition of the tool arm.
Marking the cutting line (see figure L)
Two laser beams indicate the cutting width of the saw blade.
This allows for exact positioning of the workpiece for sawing,
without having to open the retracting blade guard.
– Switch on the laser beams with the switch (32).
– Position your mark on the workpiece between the two
laser lines.

Note: Before sawing, check if the cutting width is still indic-
ated correctly Adjusting the Laser. Vibrations during intens-
ive use, for example, can cause the laser beams to become
misaligned.
Position of the operator (see figure M)
Do not stand in line with the saw blade in front of the
u
power tool. Always stand to the side of the saw blade.
This protects your body against possible kickback.
– Keep hands, fingers and arms away from the rotating saw
blade.
– Do not reach one hand across the other when in front of
the tool arm.

– 89 mm
– 100 mm (with vertical distance stop (53))
Maximum cutting width (0°/0°):
– 320 mm
– 350 mm (with horizontal distance stop (54))
Replacing the Insert Plates (see figure O)
The red insert plates (19) can become worn after prolonged
use of the power tool.
Replace defective insert plates.
– Bring the power tool into the work position.
– Loosen the screws (55) using the hex key (4 mm) and re-
move the old insert plates.
– Insert the new right-hand insert plate.
– Screw the insert plate as far as possible to the right with
the screws (55) so that the saw blade does not come into
contact with the insert plate over the entire length of the
possible slide motion.
– Repeat the work steps in the same manner for the left-
hand insert plate.
