Bosch Power Tools

To mount the key type drill chuck 

1

 turn the nut on the drive 

spindle in clockwise direction to the stop. Place the key type 

drill chuck without force onto the drive spindle until it is tightly 

seated. Apply light blows with a rubber hammer onto the face 

side of the key type drill chuck 

1

 to ensure tight seating of the 

chuck. Pay attention that the clamping jaws of the key type 

drill chuck do not project, in order not to damage them.

Mounting the securing screw

Screw the securing screw 

10

 anticlockwise into the open key 

chuck. Always use a new securing screw, as their thread is ap-

plied with a securing adhesive substance, which is rendered 

ineffective after several uses.

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.
– 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.

Reversing the rotational direction (see figure D)

The rotational direction switch 

7

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 

with the On/Off switch 

6

 actuated.

Right rotation:

 For drilling and mixing, push the rotational di-

rection switch 

7

 to the left until it stops.

Left rotation:

 For loosening or mixing, push the rotational di-

rection switch 

7

 to the right until it stops.

Switching On and Off

To 

start

 the machine, press the On/Off switch 

6

 and keep it 

pressed.
To lock the 

pressed

 On/Off switch 

6

, press the lock-on button 

5

.

To 

switch off

 the machine, release the On/Off switch 

6

 or 

when it is locked with the lock-on button 

5

, briefly press the 

On/Off switch 

6

 and then release it.

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

Adjusting the Speed

The speed of the switched-on power tool can be variably ad-

justed, depending on how far the On/Off switch 

6

 is pressed.

Light pressure on the On/Off switch 

6

 results in a low rotation-

al speed. Further pressure on the switch results in an increase 

in speed.

Work Instructions for Drilling

Use drilling lubricant or cutting oil for cooling and lubrication, 

and to avoid overheating or jamming of the drill bit.
When drilling diameters > 10 mm, drill a pilot hole with a small 

drilling diameter. This allows you to reduce the feed pressure 

and the power tool is strained less.
For drilling in metal, use only perfectly sharpened HSS drill 

bits (HSS = high-speed steel). The appropriate quality is guar-

anteed by the Bosch accessories program.
The machine vice, which is available as an accessory, enables 

secure clamping of workpieces. This prevents the workpiece 

from turning and any accidents this would cause.

Work Instructions for Mixing



Do not use the power tool in a stand. 



Avoid splashing around the material being stirred.  

Oth-

erwise, you could slip and lose control over the power tool.



Avoid continuous operation of the power tool at re-
duced speed. 

Otherwise the motor of the power tool could 

overheat.

To release the lock-on button 

5

, briefly press the on/off 

switch 

6

 and then let it go. This will prevent the power tool 

from restarting unintentionally (risk of injury).
Selection of the stirrer paddle is dependent on the material 

that is to be stirred.
For materials with low viscosity, e. g. emulsion paint, varnish-

es, adhesive, grouting compound, cement slurry, use a stirrer 

paddle with a left-hand spiral. The material is moved from the 

top downwards in a stirrer paddle with a left-hand spiral. The 

stirrer paddle is pushed upwards. Materials with low viscosity 

are mixed in a way which minimises splattering.
For materials with high viscosity, e. g. plaster, concrete, ce-

ment, screed, filler, epoxy resin, use a stirrer paddle with 

right-hand spiral. The material is moved from the bottom up-

wards in a stirrer paddle with a right-hand spiral. The stirrer 

paddle works its way into the mixture. Materials with high vis-

cosity are mixed thoroughly.
While mixing, move the power tool in an up and down motion. 

Clean the stirror paddle after use.



Store the power tool in a safe place. Ensure that it can-
not fall over. 

Otherwise, the machine may become dam-

aged.
