– Loosen the fastening screw (62) (by approx. 1–2 turns)
using the hex key (59). 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 (62).
– Check the flush alignment with the cutting line again fol-
lowing adjustment. If necessary, align the laser beams
with the set screws (58)/(60) once more.
– Reattach the laser protection cap (15).
Adjusting the lateral deviation when moving the tool arm
(see figure T4)
– Remove the four screws (61) from the laser protection
cap (15) with a cross-headed screwdriver.
Note: To reach the front screws of the laser protection
cap, you must swing the retracting blade guard (16)
backwards.
– Loosen the two fastening screws (63) (by approx. 1–2
turns) using the hex key (59).
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 (58)/(60) once more.
– Hold the laser housing in this position and retighten the
fastening screws (63).
– Reattach the laser protection cap (15).
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 (20) to the 0° detent (27). The lever
(24) 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
(20).
The leg of the angle gauge must be flush with the saw blade
(49) along its entire length.
Setting (see figure U2)
– Loosen the clamping lever (8).
– Slide the stop (45) all the way back.
– Loosen the lock nut of the stop screw (64) using a com-
mercially available box-ended or open-ended spanner
(size 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 (8).
– Then re-tighten the lock nut of the stop screw (64).
If the angle indicators (44) 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 (20) to the 0° detent (27). The
lever (24) 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 (8).
– Swivel the tool arm by the handle (13) to the left until the
stop screw (65) rests on the stop (3).
Checking (see figure V1)
– Set an angle gauge to 45° and place it on the saw table
(20).
The leg of the angle gauge must be flush with the saw blade
(49) along its entire length.
Setting (see figure V2)
– Loosen the lock nut of the stop screw (65) using a com-
mercially available box-ended or open-ended spanner
(size 10 mm).
– Turn the stop screw (65) 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 (8).
– Then retighten the lock nut of the stop screw (65).
If the angle indicators (44) and (5) are not in line with the
45° marks on the scale (4) following adjustment, first check
the 0° setting for the bevel angle and the angle indicators
once more. Then repeat the adjustment of the 45° bevel
angle.
Setting the Standard 45° Bevel Angle (right)
– Bring the power tool into the work position.
– Turn the saw table (20) to the 0° detent (27). The
lever (24) must be felt to engage in the detent.
– Remove the right-hand adjustable fence (2)
– Pull the stop (45) all the way forward.
– Turn the right-hand stop (3) until the standard 45° bevel
angle engages at the arrow mark.
– Loosen the clamping lever (8).
– Swivel the tool arm by the handle (13) to the left until the
stop screw (66) rests on the stop (3).
Checking (see figure W1)
– Set an angle gauge to 135° and place it on the saw table
(20).
