Bosch Power Tools

The battery is equipped with a NTC temperature 
control which allows charging only within a tem-
perature range of between 0 ° C and 45 ° C. A 
long battery service life is achieved in this man-
ner.
A significantly reduced working period after 
charging indicates that the battery is used and 
must be replaced.
Observe the notes for disposal.

Auxiliary Handle (GSR 18 VE-2 /
GSB 18 VE-2) (see figure A)

f

Operate your machine only with the auxilia-
ry handle 5.

The auxiliary handle 

5

 can be set to any position 

for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 

5

 in 

counterclockwise direction and swivel the auxil-
iary handle 

5

 to the desired position. Then 

retighten the bottom part of the auxiliary handle 

5

 by turning in clockwise direction.

The clamping band 

11

 of the auxiliary handle 

must be seated in the corresponding groove.

Changing the Tool (see figure B)

f

Before any work on the machine (e. g., 
maintenance, tool change, etc.) as well as 
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. 

Unintentional actuation of the On/Off 

switch can lead to injuries.

The drill spindle is locked when the On/Off 
switch 

10

 is not pressed. This makes quick, con-

venient and easy changing of the tool in the drill 
chuck possible.
Open the keyless chuck 

1

 by turning in rotation 

direction 

n

, until the tool can be inserted. Insert 

the tool.
Firmly tighten the collar of the keyless chuck 

1

by hand in rotation direction 

o

 until the locking 

action (“click”) is no longer heard. This automat-
ically locks the chuck.
The locking is released again to remove the tool 
when the collar is turned in the opposite direc-
tion.

Replacing the Drill Chuck

f

Before any work on the machine (e. g., 
maintenance, tool change, etc.) as well as 
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. 

Unintentional actuation of the On/Off 

switch can lead to injuries.

Removing the Securing Screw (see figure C)

The keyless chuck 

1

 is secured with a securing 

screw 

13

 against unintentional loosening from 

the drill spindle. Completely open the keyless 
chuck 

1

 and unscrew the securing screw 

13

 in 

rotation direction 

n

. 

Please note that the se-

curing screw has a left-hand thread.

Removing the Drill Chuck (see figure D)

Clamp the short end of an Allen key 

14

 into the 

keyless chuck 

1

.

Place the machine on a stable surface (e. g. a 
workbench). Hold the machine firmly and loos-
en the keyless chuck 

1

 by turning the Allen key 

14

 in rotation direction 

n

. Loosen a tight-seated 

keyless chuck by giving the long end of the Allen 
key 

14

 a light blow. Remove the Allen key from 

the keyless chuck and completely unscrew the 
keyless chuck.

Mounting the Drill Chuck (see figure E)

The keyless chuck is mounted in reverse order.

The drill chuck must be tightened with a 
tightening torque of approx. 32 Nm.

Screw the securing screw 

13

 in anti-clockwise 

direction into the opened keyless chuck, tight-
ening torque approx. 6 – 9 Nm. Always use a new 
securing screw, as the threads are covered with 
a thread-locking compound that loses its effect 
after multiple usage.

Dust/Chip Extraction

f

Dusts from materials such as lead-containing 
coatings, some wood types, minerals and 
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
