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 (see figure A)
 Operate your machine only with the auxiliary handle 9.
 Before any work, make sure that the wing bolt 21/18 is
tightened. Loss of control can cause personal injury.
You can mount the auxiliary handle 9 in 4 different positions
in order to achieve a safe work posture that minimises your fa-

auxiliary handle 9 in the required position over the drill chuck
onto the spindle collar of the power tool.
Turn the wing bolt 21/18 clockwise to retighten it.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the depth stop
23.
Press the button for depth stop adjustment 22 and insert the
depth stop into the auxiliary handle 9.
The knurled surface of the depth stop 23 must face down-
ward.
Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop corresponds with the
desired drilling depth X.
Drill Assistant
Attaching the Drill Assistant (see figures C–D)
The Drill Assistant 10 can be used with and without dust col-
lection device 13. Use of the dust collection device 13 is lim-
ited to drill bits with a diameter of 12 mm and a length of
120 mm.
Attach the dust collection device 13 to the mounting 26.
Press the unlocking button 8 to release the Drill Assistant 10
from its parked position.
Guide the Drill Assistant 10 over the drill chuck onto the spin-
dle collar of the power tool.
Lock it by turning the wing bolt 18 in clockwise direction.
