Noise/Vibration Information

Measured values determined according to 
EN 60745.
Typically the A-weighted noise levels of the 
product are: Sound pressure level 82 dB(A); 
Sound power level 93 dB(A). Uncertainty 
K = 3 dB.

Wear hearing protection!

Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Drilling into metal: Vibration emission value 
a

h

= 6.9 m/s

2

, Uncertainty K = 1.5 m/s

,

Screwdriving: Vibration emission value 
a

h

= 4.0 m/s

2

, Uncertainty K = 1.5 m/s

.

The vibration emission level given in this infor-
mation sheet has been measured in accordance 
with a standardised test given in EN 60745 and 
may be used to compare one tool with another. 
It may be used for a preliminary assessment of 
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However 
if the tool is used for different applications, with 
different accessories or poorly maintained, the 
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total 
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times 
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal working period.
Identify additional safety measures to protect 
the operator from the effects of vibration such 
as: maintain the tool and the accessories, keep 
the hands warm, organisation of work patterns. 

Declaration of Conformity

We declare under our sole responsibility that 
the product described under “Technical Data” is 
in conformity with the following standards or 
standardization documents: EN 60745 accord-
ing to the provisions of the directives 
2004/108/EC, 98/37/EC (until 28 Dec 2009), 
2006/42/EC (from 29 Dec 2009).

Assembly

Changing the Tool

f

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

f

Wear protective gloves when changing the 
tool. 

The drill chuck can become very hot 

during longer work periods.

Keyless Chuck (see figure A)

Hold the rear sleeve 

3

 of the keyless chuck 

1

 tight 

and turn the front sleeve 

2

 in rotation direction 

n

, 

until the tool can be inserted. Insert the tool.
Hold the rear sleeve 

3

 of the keyless chuck 

1

tight and firmly tighten the front sleeve 

2

 by 

hand in rotation direction 

o

, until the locking 

action (click) is heard. The drill chuck is locked 
automatically.
The locking is released again to remove the tool 
when the front sleeve 

2

 is turned in the opposite 

direction.

Screwdriver Tools (see figure B)

When working with screwdriver bits 

8

, a univer-

sal bit holder 

9

 should always be used. Use only 

screwdriver bits that fit the screw head.

Replacing the Drill Chuck

For machines without spindle lock, the drill 
chuck must be replaced through an authorized 
after-sales service agent for Bosch power tools.

The drill chuck must be tightened with a 
tightening torque of approx. 31 – 35 Nm.
