– Turn the rear set screw (64) using the hex key (18) until
the entire length of the right-hand laser beam is flush with
the cutting line marked on the workpiece.
This also moves the left-hand laser beam.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
2. Adjusting the left-hand laser beam:
– Turn the front set screw (64) using the hex key (18) until
the left-hand laser beam is the same distance away from
the cutting line marked on the workpiece as the right-
hand laser beam.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
– Reattach the laser protection cap (27).
Adjusting the parallelism (see figure T4)
– Remove the laser protection cap (27).
– Loosen the fastening screw (65) (by approx. 1–2 turns)
using the hex key (18). Do not unscrew the screw com-
pletely.
– Move the laser mounting plate to the right or left until the
laser beams are parallel with the marked cutting line on
the workpiece along their entire length.
– Hold the laser mounting plate in this position and
retighten the fastening screw (65).
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If required, use the set screws (64) to
align the laser beams again.
– Reattach the laser protection cap (27).
Adjusting the side deviation when moving the glide arm
(see figure T5)
– Remove the laser protection cap (27).
– Loosen the two fastening screws (66) (by approx. 1–2
turns) using the hex key (18).
Do not completely unscrew the screws.
– Move the laser housing to the right or left until the laser
beams no longer deviate at the sides when moving the
glide arm down.
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If required, use the set screws (64) to
align the laser beams again.
– Hold the laser housing in this position and retighten the
fastening screws (66).
– Reattach the laser protection cap (27).
Checking and Adjusting the Basic Settings
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use. Experience and suitable special tools are required for
this.
A Bosch after-sales service point will handle this work
quickly and reliably.

Setting the Standard 0° Bevel Angle
– Bring the power tool into the transport position.
– Turn the saw table (38) to the 0° detent (15). The lever
(12) must be felt to engage in the detent.
Checking (see figure U1)
– Set an angle gauge to 90° and place it on the saw table
(38).
The leg of the angle gauge must be flush with the saw blade
(40) along its entire length.
Setting (see figure U2)
– Loosen the clamping handle (13).
– Loosen the two set screws (67) (by at least one turn) us-
ing a socket spanner (10 mm).
– Loosen the set screw (69) (by approx. three turns) using
the hex key (4 mm) (17).
– Tighten or loosen the set screw (68) using the hex key (4
mm) (17) until the leg of the angle gauge is flush with the
saw blade along its entire length.
– Retighten the clamping handle (13). Then tighten the set
screw (69) followed by the set screws (67).
If the angle indicators (33) and (21) are not in line with the
0° marks on the scale (32) following adjustment, loosen the
fastening screws on the angle indicators using a cross-
headed screwdriver and align the angle indicators with the
0° marks.
Setting the Standard 45° Mitre Angle (left)
– Bring the power tool into the work position.
– Turn the saw table (38) to the 0° detent (15). The lever
(12) must be felt to engage in the detent.
– Pull the left-hand adjustable fence (5) all the way out.
– Loosen the clamping handle (13) and swivel the glide arm
to the left stop (45°) by the handle (1).
Checking (see figure V1)
– Set an angle gauge to 45° and place it on the saw table
(38).
The leg of the angle gauge must be flush with the saw blade
(40) along its entire length.
Setting (see figure V2)
– Tighten or loosen the set screw (70) using an open-ended
spanner (8 mm) until the leg of the angle gauge is flush
with the saw blade along its entire length.
– Retighten the clamping handle (13).
If the angle indicators (33) and (21) are not in line with the
45° marks on the scale (32) following adjustment, first
check the 0° setting for the bevel angle and the angle indicat-
ors once more. Then repeat the adjustment of the 45° bevel
angle.
Setting the Standard 45° Mitre Angle (right)
– Bring the power tool into the work position.
– Turn the saw table (38) to the 0° detent (15). The lever
(12) must be felt to engage in the detent.
– Pull the right-hand adjustable fence (5) all the way out.
– Loosen the clamping handle (13).
