Setting mitre angles (see figure L)
The mitre angle can be set between 47° (left side) and 47°
(right side).
– Loosen the locking knob (19) if it is tightened.
– Pull the lever (20) and turn the saw table (17) until the
angle indicator (22) shows the desired mitre angle.
– Retighten the locking knob (19).
For quick and precise setting of commonly used mitre
angles, detents (23) are provided on the saw table:
Left
0°
45°; 22.5°; 15°
– Loosen the locking knob (19) if it is tightened.
– Pull the lever (20) and rotate the saw table (17) left or
right to the required detent.
– Release the lever again. The lever must be felt to engage
in the detent.
– Retighten the locking knob (19).
Setting the bevel angle (see figure M)
The bevel angle can be set between 0° and 45°.
– Pull the adjustable fence (25) all the way out.
– Loosen the clamping handle (31).
– Use the handle (9) to swivel the tool arm until the angle
indicator (38) shows the required bevel angle.
– Hold the tool arm in this position and retighten the clamp-
ing handle (31).
End stops are provided on the housing that enable the
standard angles of 0° and 45° to be set quickly and accur-
ately.
– Pull the adjustable fence (25) all the way out.
– Loosen the clamping handle (31).
– To do this, swivel the tool arm by the handle (9) as far as
it will go to the right (0°) (40) or as far as it will go to the
left (45°) (28).
– Retighten the clamping handle (31).
Start-up
Inserting the Battery
Use only original Bosch lithium-ion batteries with the
u
voltage stated on the type plate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
– Push the charged battery (34) down into the battery bay
of the power tool until the battery is securely locked.
Switching on (see figure N)
– To start the power tool, first press the lock-off button
(7). Then press the on/off switch (8) all the way in and
keep it pressed.
Note: For safety reasons, the on/off switch (8) cannot be
locked; it must remain pressed during the entire operation.

Switching off

– To switch off, release the on/off switch (8).

Practical advice

General sawing instructions
Always tighten the locking knob (19) and the clamp-
u
ing handle (31) 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.
Right
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
15°; 22.5°; 45°
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 downward. When the tool
arm is guided upward, the retracting blade guard must close
again over the saw blade.
Only saw materials which are permitted within the scope of
the intended use.
Marking the cutting line (see figure O)
A laser beam shows you 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 beam by briefly pressing
the on/off switch (8) without pressing the lock-off button
(7).
– Align your mark on the workpiece with the right-hand
edge of the laser line.
Note: Before sawing, check if the cutting line is still indic-
ated correctly (see "Adjusting the laser", page 35). The
laser beam can be misplaced due to vibrations from intens-
ive use, for example.
Position of the operator (see figure P)
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.
