Bosch Power Tools

Removal of the Saw Blade (see figure A)

For changing the cutting tool, it is best to place the machine 
on the face side of the motor housing.
– Press the spindle lock button 

14

 and keep it pressed.



The spindle lock button 14 may be actuated only when 

the saw spindle is at a standstill. 

Otherwise, the power 

tool can be damaged.

– With the Allen key 

16

, unscrew the clamping bolt 

22

 turn-

ing in rotation direction 



.

– Tilt back the retracting blade guard 

7

 and hold firmly.

– Remove the clamping flange 

21

 and the saw blade 

20

 from 

the saw spindle 

18

.

Mounting the Saw Blade (see figure A)

For changing the cutting tool, it is best to place the machine 
on the face side of the motor housing.
– Clean the saw blade 

20

 and all clamping parts to be assem-

bled.

– Tilt back the retracting blade guard 

7

 and hold firmly.

– Place the saw blade 

20

 onto the mounting flange 

19

. The 

cutting direction of the teeth (direction of arrow on the saw 
blade) and the direction-of-rotation arrow on the retract-
ing blade guard 

7

 must correspond.

– Mount the clamping flange 

21

 and screw in the clamping 

bolt 

22

 turning in rotation direction 



. Observe correct 

mounting position of mounting flange 

19

 and clamping 

flange 

21

.

– Press the spindle lock button 

14

 and keep it pressed.

– Tighten the clamping bolt 

16

 with the Allen key 

22

 by turn-

ing in rotation direction 



. The tightening torque is 

6 – 9 Nm,  which  corresponds  to  hand tight plus ¼ turn or 
3 graduation marks of the marks 

23

 on the blade guard

Dust/Chip Extraction



Before any work on the power tool, remove the battery.



Dusts from materials such as lead-containing coatings, 
some wood types, minerals and metal can be harmful to 
one’s health. Touching or breathing-in the dusts can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered 
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials 
containing asbestos may only be worked by specialists.
– To achieve a high degree of dust extraction, use the vac-

uum cleaner type GAS 25/GAS 50/GAS 50 M for wood 
or GAS 50 MS for wood and/or mineral dust in conjunc-
tion with this power tool.

– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the 
materials to be worked.

Mounting the Extraction Adapter (see figure B)

Fasten the extraction adapter 

26 

to the base plate 

6

 with the 

fastening screw 

25

.

A vacuum hose with a diameter of 35 mm can be connected to 
the extraction adapter 

26

.



The extraction adapter may not be mounted when no 

external dust extraction is connected. 

Otherwise the ex-

traction channel can become clogged.



Do not connect a dust bag to the extraction adapter. 

Otherwise the extraction system can become clogged.

To ensure optimum extraction, the extraction adapter 

26

must be cleaned regularly.

External Dust Extraction

Connect the vacuum hose 

27

 to a vacuum cleaner (accesso-

ry). An overview for connecting to various vacuum cleaners 
can be found at the end of this manual.

The vacuum cleaner must be suitable for the material being 
worked.

When vacuuming dry dust that is especially detrimental to 
health or carcinogenic, use a special vacuum cleaner.

Operation

Operating Modes



Before any work on the power tool, remove the battery.

Adjusting the Cutting Depth (see figure C)



Adjust the cutting depth to the thickness of the work-

piece. 

Less than a full tooth of the blade teeth should be 

visible below the workpiece.

Loosen the clamping lever 

29

. For a smaller cutting depth, 

pull the saw away from the base plate 

6

; for a larger cutting 

depth, push the saw toward the base plate 

6

. Adjust the de-

sired cutting depth at the cutting-depth scale. Tighten the 
clamping lever 

29

 again.

The tightening tension of the clamping lever 

29

 can be readjust-

ed. For this, unscrew the clamping lever 

29

, and screw it back 

again turned offset by at least 30° in anticlockwise direction.

Adjusting the Cutting Angle

It is best to place the machine on the face side of the blade 
guard 

4

.

Loosen wing bolt 

11

. Tilt the saw sidewards. Adjust the de-

sired setting at the scale 

13

. Tighten wing bolt 

11

 again.

Note: 

For bevel cuts, the cutting depth is smaller than the set-

ting indicated on the cutting-depth scale 

28

.

Cutting Marks

The 0 °  cutting mark (

9

) indicates the position of the saw 

blade for right-angled cuts. The 45 °  cutting mark (

10

) indi-

cates the position of the saw blade for 45 °  cuts.

For precise cuts, position the circular saw against the work-
piece as shown in the figure. It is best to carry out a trial cut.
