Bosch Power Tools

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 machine into the transport position.
– Turn the saw table 

18

 to the 0 ° detent 

17

. The lever 

15

must be felt to engage in the detent.

Checking:

 (see figure  S1)

– 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 

9

over the complete length.

Adjusting:

 (see figure S2)

– Loosen the lock lever 

16

.

– Loosen set screws 

60

 and 

61

 with the supplied open-end 

spanner 

3

 (10 mm).

– Loosen set screw 

62

 (approx. 3 turns) with the supplied 

hex key 

35

 (4 mm).

– Screw  set  screw 

59

 (10 mm) in or out until the leg of the 

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

– Retighten the lock lever 

16

 again.

Afterwards, tighten set screw 

62

 first, and then set screws 

60

 and 

61

.

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 the supplied cross-head screwdriv-
er 

35

 and align the angle indicators alongside the 0 ° marks.

Setting the Standard 45 ° Bevel Angle (Leftward)

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

18

 to the 0 ° detent 

17

. The lever 

15

must be felt to engage in the detent.

– Pull the left fence extension 

21

 completely outward. 

– Loosen the lock lever 

16

 and tilt the tool arm leftward to 

the stop (45 °) by the handle 

7

.

Checking:

 (see figure T1)

– 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 

9

over the complete length.

Adjusting:

 (see figure T2)

– Screw  set  screw 

63

 (10 mm) in or out until the leg of the 

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

– Retighten the lock lever 

16

 again.

When the angle indicators 

33

 and 

24

 are not in line with the 

45 ° marks of scale 

32

 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.

Adjusting the Clamping Force of Lock Lever 16 
(see figure T2)

The clamping force of lock lever 

16

 can be readjusted.

Checking:

– The clamping force of the clamping lever must securely 

hold the position of the tool arm at any bevel angle.

Adjusting:

– Loosen the lock lever 

16

.

– Turn set screw 

64

 in anticlockwise direction with the sup-

plied open-end spanner 

3

 (17 mm) to reduce the clamping 

force, or increase the clamping force by turning in clock-
wise direction.

– Adjust a vertical bevel angle, retighten lock lever 

16

 and 

check if the desired clamping force has been reached.

Adjusting the Clamping Force of Clamp 5 (see figure  U)

The clamping force of the handle clamp 

5

 can be readjusted.

Checking:

– The clamping force of the clamp must securely hold the 

handle in any of the 4 possible positions.

Adjusting:

– Open clamp 

5

.

– Turn both set screws 

65

 in anticlockwise direction with the 

supplied hex key 

2

 (1.5 mm) to reduce the clamping force, 

or increase the clamping force by turning in clockwise di-
rection.
Always adjust both set screws to the same height.

– Shut  clamp 

5

 and check if the desired clamping force has 

been reached.

Aligning the Angle Indicator (Horizontally) (see figure V)

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

18

 to the 0 ° detent 

17

. The lever 

15

must be felt to engage in the detent.

Checking:

The angle indicator 

66

 must be in alignment with the 0 ° mark 

of the scale 

40

.

Adjusting:

– Loosen the fastening screw of the angle indicator with the 

supplied cross-head screwdriver 

35

 and align the angle in-

dicator alongside the 0 ° mark.

– Retighten the screw again.

Aligning the Fence

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

18

 to the 0 ° detent 

17

. The lever 

15

must be felt to engage in the detent.

Checking:

 (see figure W1)

– Adjust an angle gauge to 90 ° and position it flush with the 

saw blade 

9

 between the fence 

20

 and the saw blade on 

the saw table 

18

.

The leg of the angle gauge must be flush with the fence over 
the complete length.
