Bosch Power Tools

Approved Grinding Tools

All grinding tools mentioned in these operating instructions 
can be used.

The permissible speed [min

-1

] or the circumferential speed 

[m/s] of the grinding tools used must at least match the values 
given in the table.

Therefore, observe the permissible 

rotational/circumferen-

tial speed

 on the label of the grinding tool.

Rotating the Machine Head



Before any work on the machine itself, pull the mains 
plug.

The machine head can be 
rotated with respect to 
the machine housing in 
90 ° steps. In this man-
ner, the On/Off switch 
can be brought into a 
more convenient posi-
tion for special working 
situations, e. g., for cut-
ting operations using the 
cutting guide with dust 
extraction protection 
guard 

21

 or for left-hand-

ed persons.

Completely unscrew the four screws. Rotate the machine 
head carefully, 

without removing it from the housing,

 to the 

new position. Screw in and tighten the four screws again.

Dust/Chip Extraction



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.

– As far as possible, use a dust extraction system suitable 

for the material.

– 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 mate-
rials to be worked.



Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

Operation

Starting Operation



Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the 
nameplate of the machine. Power tools marked with 
230 V can also be operated with 220 V.

When operating the machine with power from mobile genera-
tors that do not have sufficient reserve capacity or are not 
equipped with suitable voltage control with starting current 
amplification, loss of performance or untypical behavior can 
occur upon switching on.
Please observe the suitability of the power generator being 
used, particularly with regard to the mains voltage and fre-
quency.

Switching On and Off

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

To 

start

 the power tool, press the On/Off switch 

4

 forward 

and then down.

To 

lock-on

 the pressed On/Off switch 

4

, push the On/Off 

switch 

4

 further forward.

To 

switch off

 the power tool, release the On/Off switch 

4

, or 

when it is locked, briefly press the On/Off switch 

4

 and then 

release it.

Switch Version without Lock-on (country-specific):

To 

start

 the power tool, press the On/Off switch 

4

 forward 

and then down.

To

 the machine, release the On/Off switch 

4

.



Check grinding tools before using. The grinding tool 
must be mounted properly and be able to move freely. 
Carry out a test run for at least one minute with no load. 
Do not use damaged, out-of-centre or vibrating grind-
ing tools. 

Damaged grinding tools can burst and cause in-

juries.

Kickback stop

In case of a sudden drop in speed, e.g., 
caused by a jammed disc while cutting, the 
power supply to the motor is electronically 
interrupted.

To 

restart the operation

, switch the 

On/Off switch 

4

 to the Off position and start 

the machine again.
