Practical advice

Marking the Cutting Line (see figure P)
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 (6) without pressing the lock-off
button (5).
– 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 24). Vibra-
tions during intensive use, for example, can cause the laser
beams to become misaligned.
Permissible workpiece dimensions
Maximum workpiece dimensions:
Mitre angle
Bevel angle
45° (left/right)
45° (left)
45° (left)
45° (right)
45° (right)
45° (left)
45° (right)
Minimum workpiece dimensions (= all workpieces that can
be secured left or right of the saw blade using the supplied
screw clamps (41)): 100 x 40 mm (length x width)
Maximum cutting depth (0°/0°): 66 mm
Adjusting the Depth Stop (Sawing the Groove) (see
figure Q)
The depth stop needs to be adjusted if you wish to saw a
groove.
– Swivel the depth stop (39) forwards.
– Swivel the tool arm by the handle (7) into the required
position.
– Turn the adjusting screw (38) until the end of the screw
touches the depth stop (39).
– Slowly guide the tool arm upwards.
Sawing workpieces of the same length (see figure R)
The left or right length stop (36) can be used for easily saw-
ing workpieces of the same length.
– Turn the length stop (36) upwards.
– Set the saw table extension (23) to the required work-
piece length.
Special workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, there
should be no gap between the workpiece, fence and saw
table.
If necessary, you will need to manufacture special fixtures.

Replacing insert plates (see figure S)
The insert plates (14) can become worn after prolonged use
of the power tool.
Replace faulty insert plates.
– Bring the power tool into the work position.
– Unscrew the screws (54) using a commercially available
cross-headed screwdriver and remove the old insert
plate (14).
– Insert the new insert plate and screw the screws (54) in
tight again.

Adjusting the laser

Note: To test the laser function, the power tool must be con-
nected to the power supply.
While adjusting the laser (e.g. when moving the tool
u
arm), never activate the on/off switch. Starting the
power tool accidentally can lead to injuries.
Height x width
– Bring the power tool into the work position.
[mm]
– Turn the saw table (12) to the 0° detent (20). The lever
66 x 305
(17) must be felt to engage in the detent.
66 x 215
To ensure precise cuts, the laser beams must be checked
and adjusted as necessary after intensive use.
42 x 215
Experience and suitable special tools are required for this.
20 x 215
A Bosch after-sales service point will handle this work
42 x 305
quickly and reliably.

Checking (see figure T1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the tool arm downwards using the
handle (7).
– Position the workpiece so that the teeth of the saw blade
line up with the cutting line.
– Hold the workpiece in this position and slowly guide the
tool arm back up.
– Clamp the workpiece.
– Turn on the laser beams using the switch (6) without
pressing the lock-off button (5).
The laser beams must be at the same distance from the
marked cutting line on the workpiece left and right along the
entire length, even if the tool arm is being guided down-
wards.
Removing the Laser Protection Cap (see figure T2)
– Unscrew the two screws (55) of the laser protection
cap (8) using a hex key/slotted screwdriver (43) and re-
move the laser protection cap.
Adjusting the Lateral Deviation when Moving the Tool
Arm (see figures T3−T4)
– Loosen the fastening screw (56) (by approx. one to two
turns).
Do not unscrew the screw completely.
– Move the laser housing (57) right or left until the laser
beams no longer laterally deviate when the tool arm
moves downwards.
– Hold the laser housing (57) in this position and retighten
the fastening screw (56).
