Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted sound pressure level of
the product is 75 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed
80 dB(A).
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Drilling into metal: Vibration emission value
2
a =2.5 m/s , Uncertainty K =1.5 m/s
h
Screwdriving: Vibration emission value
2
a <2.5 m/s , Uncertainty K =1.5 m/s
h
The vibration emission level given in this informa-
tion 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 ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing 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 total
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.

Auxiliary Handle (see figure A)
Operate your machine only with the auxiliary
handle 8.
The auxiliary handle 8 can be set to any position
for a secure and low-fatigue working posture.
Turn the wing bolt for adjustment of the auxiliary
handle 7 in anticlockwise direction and set the
auxiliary handle 8 to the required position. Then
tighten the wing bolt 7 again in clockwise direc-
tion.
Adjusting the Drilling Depth
The required drilling depth X can be set with the
depth stop 9.
Loosen the wing bolt for the depth stop adjust-
ment 6 and insert the depth stop rod into the
auxiliary handle 8.
The knurled surface of the depth stop 9 must
face upward.
Pull out the depth stop until the distance be-
tween the tip of the drill bit and the tip of the
depth stop correspond with the desired drilling
depth X.
Retighten the wing bolt for the depth stop adjust-
ment 6 again.
