To 

switch off

 the machine, release the On/Off 

switch 

5

 or when it is locked with the lock-on but-

ton 

4

, briefly press the On/Off switch 

5

 and then 

release it.

Adjusting the Speed/Impact Frequency 
(GSB 18-2 RE)

The speed/impact rate of the switched on power 
tool can be variably adjusted, depending on how 
far the On/Off switch 

5

 is pressed.

Light pressure on the On/Off switch 

5

 results in 

low speed/impact rate. Further pressure on the 
switch increases the speed/impact rate.

Preselecting the Speed/Impact Frequency 
(GSB 18-2 RE)

With the thumbwheel for speed preselection 

6

, 

the required speed/impact frequency can be 
preselected even during operation.
The required speed/impact frequency depends 
on the material and the working conditions, and 
can be determined through practical testing.

Working Advice

f

Apply the power tool to the screw/nut only 
when it is switched off. 

Rotating tool inserts 

can slip off.

Tips

After longer periods of working at low speed, al-
low the machine to cool down by running it for 
approx. 3 minutes at maximum speed with no 
load.
For drilling in tiles, set the selector switch 

2

 to 

the “Drilling” symbol. Do not switch over to the 
symbol “Impact Drilling” or work with impact un-
til after drilling through the tile.
Use carbide tipped drill bits when working in 
concrete, masonry and brick wall.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS = high-speed steel). The 
appropriate quality is guaranteed by the Bosch 
accessories program.
Twist drills from 

2,5 – 10

mm can easily be sharp-

ened with the drill bit sharpener (see accesso-
ries).

Soft Grip

The gripping surface (soft grip) 

3

 reduces the 

danger of slipping and thereby improves the grip 
on the machine and the handling.
At the same time, the rubber coating achieves a 
vibration-reducing effect.

Maintenance and Service

Maintenance and Cleaning

f

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

f

For safe and proper working, always keep 
the machine and ventilation slots clean.

If the machine should fail despite the care taken 
in manufacturing and testing procedures, repair 
should be carried out by an after-sales service 
centre for Bosch power tools.
In all correspondence and spare parts order, 
please always include the 10-digit article number 
given on the type plate of the machine.

ing a new 3-pin plug to the 2-wire cable.

The wires in the cable are coloured according to 
the following code:

Do 

not

 connect the blue or brown wire to the 

earth terminal of the plug.

Important:

 If for any reason the moulded plug is 

removed from the cable of this power tool, it 
must be disposed of safely.
