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
2
a =6.9 m/s , Uncertainty K=1.5 m/s
h
Screwdriving: Vibration emission value
2
a =4.0 m/s , Uncertainty K=1.5 m/s
h
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.

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