3.- Assembly
f
Before any work on the machine itself, pull
the mains plug.
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 oned in the groove on the housing handle is positi
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.
3.3.- Carrying Handle (HD15K / HD17K)
The carrying handle 13 can be turned to any posi-
tion. Loosen the knurled nut 14 , turn the carrying
handle 13 around the machine axis to the desired
position and tighten the knurled nut 14 again.
The carrying handle 13 can also be mounted facing
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
the carrying handle
13 in reverse order.
