Adjusting the Lateral Deviation while Moving the Tool
Arm: (see figure S4)
– Remove the four screws 62 of the laser protection cap 14
with a cross-head screwdriver.
Note: You have to swing the retracting blade guard back-
ward in order to reach the front screws of the laser protec-
tion cap.
– Loosen both fastening screws 64 (approx. 1–2 turns)
with the hex key (2,5 mm) 60.
Do not completely unscrew the screws.
– Move the laser housing right or left until the laser beams no
longer deviate in lateral direction when moving the tool
arm down.
– After adjusting, check the flush alignment with the cutting
line once more. If required, align the laser beams with the
set screws 57 one more time.
– Hold the laser housing in this position and tighten fasten-
ing screws 64 again.
– Reattach the laser protection cap 14 again.
Checking and Adjusting the Basic Adjustment
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use.
A certain level of experience and appropriate specialty tools
are required for this.
A Bosch after-sales service station will handle this mainte-
nance task quickly and reliably.
Setting the Standard Bevel Angle 0° (Vertical)
– Bring the power tool into the working 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)
– Adjust an angle gauge to 90° and position it on the saw ta-
ble 18.
The leg of the angle gauge must be flush with the saw blade 47
over the complete length.
Adjusting: (see figure T2)
– Loosen clamping lever 7.
– Swing the stop 42 completely inward.
– Loosen the lock nut of the stop screw 65 using a commer-
cial box-end or open-end spanner (size 10 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Tighten clamping lever 7 again.
– Afterwards, retighten the lock nut of the stop screw 65
again.
When the angle indicators 41 and 5 are not in line with the 0°
marks of scale 4 after adjusting, loosen the fastening screws
of the angle indicators with a cross-head screwdriver and
align the angle indicators alongside the 0° marks.
Bosch Power Tools
Setting the Standard 45° Bevel Angle (Leftward)
– Bring the power tool into the working 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 (see "Moving the
Fence", page 35).
– Turn the left-hand stop 3 until the standard 45° bevel angle
engages at the arrow mark.
– Loosen clamping lever 7.
– Swing the tool arm to the left by the handle 12 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
over the complete length.
Adjusting: (see figure U2)
– Loosen the lock nut of the stop screw 66 using a conven-
tional ring spanner or open-end spanner (10 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Tighten clamping lever 7 again.
– Then retighten the lock nut of the stop screw 66.
When the angle indicators 41 and 5 are not in line with the 45°
marks of scale 4 after adjusting, firstly once more check the
0° setting for the bevel angle and the angle indicators. Then
repeat the adjustment of the 45° bevel angle.
Setting the Standard 45° Bevel Angle (Rightward)
– Bring the power tool into the working position.
– Turn the saw table 18 to the 0° detent 25. The lever 22
must be felt to engage in the detent.
– Remove the right-hand adjustable fence 2 (see "Moving
the Fence", page 35).
– Swing the stop 42 completely outward.
– Turn the right-hand stop 3 until the standard 45° bevel an-
gle engages at the arrow mark.
– Loosen clamping lever 7.
– Swing the tool arm to the right by the handle 12 until the
stop screw 67 rests on the stop 3.
Checking: (see figure V1)
– Set an angle gauge to 135° and place it on the saw table
18.
The leg of the angle gauge must be flush with the saw blade 47
over the complete length.
Adjusting: (see figure V2)
– Loosen the lock nut of the stop screw 67 using a conven-
tional ring spanner or open-end spanner (10 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Tighten clamping lever 7 again.
– Then retighten the lock nut of the stop screw 67.
When the angle indicators 41 and 5 are not in line with the 45°
marks of scale 4 after adjusting, firstly once more check the
0° setting for the bevel angle and the angle indicators. Then
repeat the adjustment of the 45° bevel angle.
