3.1.- Auxiliary Handle

f Operate your machine only with the auxiliary
handle 11.
Rotating the Auxiliary Handle
The auxiliary handle 11 can be set to any position
for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 11 in
counterclockwise direction and swivel the auxiliary
handle 11 to the desired position. Then retighten
the bottom part of the auxiliary handle 11 by turning
in clockwise direction.
Pay attention that the clamping band of the auxilia-
ry handle is positi oned in the groove on the housing
as intended for.

3.2.- Changing the Tool

The dust protection cap 3 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care that
the dust protection cap 3 is not damaged.
f A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales service.
Inserting SDS-plus Drilling Tools
The SDS drill chuck allows for simple and con-
venient changing of drilling tools without the use
of additional tools.

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.
As a requirement of the system, the SDS drilling
tool can move freely. This causes a certain radial
run-out at no-load, which has no effect on the
accuracy of the drill hole, as the drill bit centres
itself upon drilling.
Removing SDS Drilling Tools
Push back the locking sleeve 4 and remove the
tool.

to the other side. Completely unscrew the knurled
nut 14 and then pull out the hexagon bolt upward.
Pull off the carrying handle 13 to the side and tilt
the remaining clamping element by 180°. Mount
