In areas where the Bluetooth® wireless technology is
u
not allowed to be used, the Bluetooth® Low Energy
Module GCY 42 and the button cell must be removed.
The free end of long and heavy workpieces must have some-
thing placed underneath it or be supported.
Do not saw warped/bent workpieces. The workpiece must
always have a straight edge to face against the fence.
Only saw materials which are permitted within the scope of
the intended use.
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
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 M)
Two laser beams indicate 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.
– To do this, switch on the laser beams by briefly pressing
the on/off switch (65) without pressing the lock-off
button (2).
– Position your mark on the workpiece between the two
laser lines.
Note: Before sawing, check if the cutting line is still indic-
ated correctly (see "Adjusting the laser", page 29). Vibra-
tions during intensive use, for example, can cause the laser
beams to become misaligned.
Position of the operator (see figure N)
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.
Replacing insert plates (see figure O)
The insert plates (10) can become worn after prolonged use
of the power tool.
Replace faulty insert plates.
– Bring the power tool into the work position.
– Loosen the screws (66) using the hex key (18) 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 (66) 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 new
left-hand insert plate.

Sawing
Sawing without slide movement (cutting off) (see
figure P)
– Slide the glide arm (34) all the way back and secure it in
this position.
Make sure that the depth stop (28) is pressed all the way
in and that the adjusting screw (27) fits through the re-
cess without touching the depth stop when moving the
glide arm.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the required mitre and/or bevel angle as necessary.
– Switch on the power tool.
– Slowly guide the glide arm (34) downwards using the
handle (1).
– Saw through the workpiece applying uniform feed.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the glide arm (34) upwards.
Sawing with Slide Movement (see figure Q)
Maintain a firm grip on the handle before switching
u
the power tool on and during the entire sawing pro-
cess. Ensure that the movement of the glide arm is
controlled during sawing. The glide arm is very easy to
move and a moment of inattention could result in serious
injury.
– Unlock the glide arm (34).
Check if the complete glide mechanism is operative by
sliding the glide arm (34) back and forth.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the required mitre and/or bevel angle as necessary.
