The vibration emission 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
another. It may be used for a preliminary assessment of expo-
sure.
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 poorly maintained,
the vibration emission may differ. This may significantly in-
crease 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 pe-
riod.
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
f
Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle (see figure A)
f
Operate your machine only with the auxiliary handle 8.
The auxiliary handle
8
can be set in 12 positions to achieve a
safe and low-fatigue working stance.
Turn the bottom part of the auxiliary handle
8
in rotation di-
rection
n
and push the auxiliary handle
8
forward until you
can pivot it to the desired position. Then pull the auxiliary han-
dle
8
back again and tighten it by turning the bottom part of
the auxiliary handle in rotation direction
o
.
Adjusting the Drilling Depth (see figure A)
The required drilling depth
X
can be set with the depth stop
9
.
Turn the bottom part of the auxiliary handle
8
in anticlockwise
direction and insert the depth stop
9
.
Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop correspond with the
desired drilling depth
X
.
Afterwards, tighten the bottom part of the auxiliary handle
8
again by turning in clockwise direction.
The knurled surface of the depth stop
9
must face upward.
