Adjusting the flush alignment (see figure S2)
1. Adjusting the right-hand laser beam:
– Turn the set screw (59) with the hex key (60) until the
right-hand laser beam is flush with the marked cutting line
on the workpiece along the entire length.
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 set screw (61) with the hex key (60) until the
left-hand laser beam is at the same distance from the
marked cutting line 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.
Adjusting the parallelism (see figure S3)
– Remove the four screws (62) from the laser protection
cap (14) with a cross-headed screwdriver.
Note: To reach the front screws of the laser protection
cap, you must swing the retracting blade guard (15)
backwards.
– Remove the laser protection cap (14).
– Loosen the fastening screw (63) (by approx. 1–2 turns)
using the hex key (60). 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 (63).
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If necessary, align the laser beams
with the set screws (59)/(61) once more.
– Reattach the laser protection cap (14).
Adjusting the lateral deviation when moving the tool arm
(see figure S4)
– Remove the four screws (62) from the laser protection
cap (14) with a cross-headed screwdriver.
Note: To reach the front screws of the laser protection
cap, you must swing the retracting blade guard (15)
backwards.
– Loosen the two fastening screws (64) (by approx. 1–2
turns) using the hex key (60).
Do not completely unscrew the screws.
– Move the laser housing right or left until the laser beams
no longer laterally deviate when the tool arm moves
downwards.
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If necessary, align the laser beams
with the set screws (59)/(61) once more.
– Hold the laser housing in this position and retighten the
fastening screws (64).
– Reattach the laser protection cap (14).

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 (18) to the 0° detent (25). The lever
(22) must be felt to engage in the detent.
Checking (see figure T1)
– Set an angle gauge to 90° and place it on the saw table
(18).
The leg of the angle gauge must be flush with the saw blade
(47) along its entire length.
Setting (see figure T2)
– Loosen the clamping lever (7).
– Swing the stop (42) all the way in.
– Loosen the lock nut of the stop screw (65) with a com-
mercially available ring or open-ended spanner (10 mm).
– Turn the stop screw as far in or out as needed until the leg
of the angle gauge is flush with the saw blade along its en-
tire length.
– Re-tighten the clamping lever (7).
– Then re-tighten the lock nut of the stop screw (65).
If the angle indicators (41) and (5) are not in line with the 0°
marks on the scale (4) 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 (18) to the 0° detent (25). The
lever (22) must be felt to engage in the detent.
– Remove the left-hand adjustable fence (2)
– Turn the left-hand stop (3) until the standard 45° mitre
angle engages at the arrow mark.
– Loosen the clamping lever (7).
– Swivel the tool arm by the handle (12) to the left until the
stop screw (66) rests on the stop (3).
Checking (see figure U1)
– Set an angle gauge to 45° and place it on the saw table
(18).
The leg of the angle gauge must be flush with the saw blade
(47) along its entire length.
Setting (see figure U2)
– Loosen the lock nut of the stop screw (66) using a com-
mercially available box-ended or open-ended spanner
(size 10 mm).
– Turn the stop screw (66) as far in or out as needed until
the leg of the angle gauge is flush with the saw blade along
its entire length.
– Retighten the clamping lever (7).
