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.

Adjusting the Laser
Note: 

To test the laser function, the machine must be con-

nected to power.



While adjusting the laser (e.g. when moving the glide 
arm), never actuate the On/Off switch. 

Accidental start-

ing of the power tool can lead to injuries.

– Bring the power tool into the working position.
– Turn the saw table 

38

 to the 0 ° detent 

18

. The lever 

16

must be felt to engage in the detent.

– Switch on the laser beams with switch 

61

.

Checking:

 (see figure T1)

– Draw a straight cutting line on the workpiece.
– Press locking lever 

5

 and slowly guide the glide arm down-

ward with handle 

4

.

– Align the workpiece in such a manner that the teeth of the 

saw blade are in alignment with the cutting line.

– Hold the workpiece in this position and slowly guide the 

glide arm upward.

– Clamp the workpiece.
– Switch on the laser beams with switch 

61

.

Throughout the complete length, the laser beams must have 
the same clearance to the drawn cutting line on the work-
piece, even when lowering the glide arm.

Adjusting the Flush Levelling:

 (see figure T2)

– Using the hex key (2 mm) 

21

, turn the respective adjust-

ment screw 

64

 until the laser beam has the same clearance 

to the drawn cutting line on the workpiece over the com-
plete length.

One rotation in anticlockwise direction moves the laser beam 
from left to right; one rotation in clockwise direction moves 
the laser beam from right to left.

Adjusting the Parallelism:

 (see figure T3)

– Loosen the two screws 

65

 of laser protection cap 

27

 with 

the hex key (4 mm) 

20

.

Note: 

To access the front screw of the laser protection 

cap, the glide arm must be tilted down a little until the hex 
key can be inserted through one of the slots of the retract-
ing blade guard.

– Loosen fastening screw

66

 (approx. 1 – 2 turns) with the 

hex key (2 mm) 

21

.

Do not completely unscrew the screw.

– Move the mounting plate of the laser right or left until the 

laser beams are parallel to the drawn cutting line on the 
workpiece over the complete length.

– Hold the mounting plate in this position and tighten fasten-

ing screw 

66

 again.

– After adjusting, check the flush alignment with the cutting 

line once more. If required, align the laser beams with the 
set screws 

64

 one more time.

– Reattach the laser protection cap 

27

 again.

Adjusting the Lateral Deviation when Moving the Glide 
Arm:

 (see figure T4)

– Loosen the two screws 

65

 of laser protection cap 

27

 with 

the hex key (4 mm) 

20

.

Note: 

To access the front screw of the laser protection 

cap, the glide arm must be tilted down a little until the hex 
key can be inserted through one of the slots of the retract-
ing blade guard.

– Loosen both fastening screws

67

 (approx. 1 – 2 turns) 

with the hex key (2 mm) 

21

.

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 glide 
arm down.

– After adjusting, check the flush alignment with the cutting 

line once more. If required, align the laser beams with the 
set screws 

64

 one more time.

– Hold the laser housing in this position and tighten fasten-

ing screws 

67

 again.

– Reattach the laser protection cap 

27

 again.

Setting the Standard Bevel Angle 0 ° (Vertical)

– Bring the machine into the transport position.
– Turn the saw table 

38

 to the 0 ° detent 

18

. The lever 

16

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

over the complete length.

Adjusting:

 (see figure U2)

– Loosen the lock lever 

17

.

– Loosen both set screws 

68

 (by at least 1 turn) using a sock-

et spanner (size 10 mm).

– Loosen set screw

70

 (approx. 3 turns) with the hex key 

(4 mm) 

20

.

– Screw  set  screw 

69

 with the hex key (4 mm) 

20

 in or out 

until the leg of the angle gauge is flush with the saw blade 
over the complete length.

– Retighten the lock lever 

17

 again.

Afterwards, tighten set screw 

70

 first, and then set screws 

68

.

When the angle indicators 

33

 and 

24

 are not in line with the 

0 °  marks  of  scale 

32

 after adjusting, loosen the fastening 

screws of the angle indicators with a cross-head screwdriver 
and align the angle indicators alongside the 0 ° marks.
