Bosch Power Tools

– Place  the  saw  blade 

24

 onto the mounting flange 

23

. 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 

20

 must correspond.

– Mount  the  clamping  flange 

25

 and screw in the clamping 

bolt 

26

 turning in rotation direction 



. Observe correct 

mounting position of mounting flange 

23

 and clamping 

flange 

25

.

– Press the spindle lock button 

6

 and keep it pressed.

– With the hex key 

5

, tighten the clamping bolt 

26

 turning in 

rotation direction 



. The tightening torque is between 

6 – 9 Nm, which corresponds to hand tight plus ¼ turn.

Dust/Chip Extraction



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



Dust 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 dust can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment 
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– To achieve a high level of dust extraction, use a suitable 

dust extractor together 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 

30 

to the base plate 

7

 with the 

fastening screw 

29

.

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

30

.



The extraction adapter may not be mounted when no 
external dust extraction is connected. 

Otherwise the ex-

traction channel can become clogged.



Neither a dust bag nor a dust box may be connected to 
the extraction adapter. 

Otherwise the extraction system 

can become clogged.

To ensure optimum extraction, the extraction adapter 

30

must be cleaned regularly.

External Dust Extraction

Connect the vacuum hose 

31

 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 wing bolt 

18

. For a smaller cutting depth, pull the ma-

chine from the base plate 

7

; for a larger cutting depth, push 

the machine toward the base plate 

7

. Adjust the desired cut-

ting depth at the cutting-depth scale 

19

. Tighten wing bolt 

18

again.

When setting the cutting depth, use the reference mark 

32

 to 

the side of the cutting-depth scale 

19

.

Adjusting the Cutting Angle

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

13

.

Loosen wing bolt 

10

. Tilt the saw sidewards. Adjust the de-

sired setting at the scale 

9

. Tighten wing bolt 

10

 again.

When setting the mitre angle, use the reference mark 

28

 (up-

per edge of the holder).

Note: 

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

ting indicated on the cutting-depth scale 

19

.

Cutting Marks (see figure F)

The 0 ° cutting mark 

12

 indicates the position of the saw blade 

for right-angled cuts. The 45 ° cutting mark 

11

 indicates the 

position of the saw blade for 45 ° cuts.

Starting Operation

Inserting the battery



Use only original Bosch lithium-ion batteries with the 
voltage listed on the nameplate of your power tool. 

Using other batteries can lead to injuries and pose a fire 
hazard.

Insert the charged battery 

2

 into the handle until it can be felt 

to engage and faces flush against the handle.

Switching On and Off

To 

start

 the machine, 

first

 push the lock-off button for the 

On/Off switch 

3

 and 

then

 press the On/Off switch 

4

 and keep 

it pressed.

To 

switch off

 the machine, release the On/Off switch 

4

.

Note: 

For safety reasons, the On/Off switch 

4

 cannot be 

locked; it must remain pressed during the entire operation.

To save energy, only switch the power tool on when using it.

Run-on Brake

An integrated run-on brake reduces the run-on period of the 
saw blade after switching off the machine.

Temperature Control/Overload Protection Indicator

The red LED indicator 

17

 will help you in protecting the bat-

tery against overheating and the motor against overloading.
