Assembly
f
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
f
Operate your machine only with the auxilia-
ry handle 10.
The auxiliary handle
10
can be set to any posi-
tion for a secure and low-fatigue working pos-
ture.
– Turn the bottom part of the auxiliary handle
10
in counterclockwise direction and swivel
the auxiliary handle
10
to the desired posi-
tion. Then retighten the bottom part of the
auxiliary handle
10
by turning in clockwise di-
rection.
Changing the Tool
With the SDS-max tool holder, simpler and eas-
ier tool changing is possible without additional
aids.
The dust protection cap
1
largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap
1
is not damaged.
f
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Inserting (see figure A)
– Clean and lightly grease the shank end of the
tool.
The red symbols (open lock and bars) on the
locking sleeve
2
indicate that the tool holder is
open.
– Insert the tool into the tool holder with a
turning motion until it is automatically
locked. The locking sleeve automatically
snaps toward the front and the red ring is no
longer visible. This indicates that the tool
holder is locked.
Removing (see figure B)
– Pull the locking sleeve
2
back until it engag-
es. The red symbols on the locking sleeve can
now be seen again. The locking sleeve re-
mains in this position and the tool can be re-
moved without having to hold the locking
sleeve.
