Noise/Vibration Information

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 90 dB(A); sound power level
101 dB(A). Uncertainty K=3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745:
2
Chiselling: a =17.5 m/s , K=1.5 m/s
h
The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running 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 pat-
terns.

Assembly
 Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 6.
The auxiliary handle 6 can be set to any position for a secure
and low-fatigue working posture.
2
.
– Turn the bottom part of the auxiliary handle 6 in counter-
clockwise direction and swivel the auxiliary handle 6 to the
desired position. Then retighten the bottom part of the
auxiliary handle 6 by turning in clockwise direction.
Changing the Tool
With the SDS-plus tool holder, simple and convenient tool
changing is possible without additional aids.
The dust protection cap 1 largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap 1 is not damaged.
 A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Inserting (see figure A)
– Clean and lightly grease the shank end of the tool.
– Insert the tool in a twisting manner into the tool holder until
it latches itself.
– Check the latching by pulling the tool.
Removing (see figure B)
– Push back the locking sleeve 2 and remove the tool.

Dust/Chip Extraction

 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
– To start the machine, press the On/Off switch 5 and keep
it pressed.
– To lock the pressed On/Off switch 5, press the lock-on
button 4.
