The vibration level given in this information sheet
has been measured in accordance with a standard-
ised 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 represents
the main applications of the tool. However if the
tool is used for different applications, with different
accessories or insertion tools or is poorly main-
tained, 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 ac-
tually doing the job. This may significantly 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.

Assembly
Before any work on the machine itself, pull the
mains plug.
Auxiliary Handle
Operate your machine only with the auxiliary
handle 10.
The auxiliary handle 10 can be set to any position
for a secure and low-fatigue working posture.
– Turn the bottom part of the auxiliary handle 10 in
counterclockwise direction and swivel the auxil-
iary handle 10 to the desired position. Then
retighten the bottom part of the auxiliary handle
10 by turning in clockwise direction.
Adjusting the Drilling Depth (see figure A)
The required drilling depth X can be set with the
depth stop 11.
– Press the button for the depth stop adjustment 9
and insert the depth stop into the auxiliary han-
dle 10.
