The “impact drilling” operating
mode may only be used if the key-
less chuck is not attached!
Changing the tool
The tool holder with SDS Plus adapter
allows you to change the attachment tool
easily and conveniently without use of ad-
ditional tools.
The attachment tool is freely movable for
technical reasons. This causes a concen-
tricity deviation during idling but this has
no effect on the accuracy of the bore hole
since the drill centres itself automatically
while drilling.
The device is capable of using various drill
bit types featuring a hexagonal or cylind-
rical shaft thanks to the keyless chuck with
SDS Plus adapter.
The dust protection cap (2) largely prevents
the ingress of drilling dust into the tool
holder during operation. Ensure the dust
protection cap (2) is not damaged when
inserting tools.
If damaged, the dust protection cap
must be replaced immediately. It is re-
commended for this to be performed
by customer service.
