Changing the Tool
Before any work on the machine itself, pull
the mains plug.
With the SDS-max tool holder, simpler and easier
tool changing is possible without additional aids.
Grease the insertion end of the tool reg-
ularly.
The dust protection cap 1 prevents to a large ex-
tent the entry of drilling dust during operation.
When inserting the tool, take care that the dust
protection cap 1 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
