machine and adjust it as desired. After that, clamp it in place.

Attaching the Tool
The machine is equipped with an SDS-Plus drill chuck (1). With this chuck tool
changes are executed in a simple and convenient way without tools.
In the SDS chuck the tool bit is guided by two rails, which also provide the
power transfer from the machine to the tool. The tool is retained in the chuck
by a steel ball.
1. Before inserting the tool, pull back the
plastic ring of the chuck. Now insert the
tool.
2. It may be necessary to slightly turn the
tool until the slots in the tool and the
rails in the chuck slide into each other.
Now the tool can be inserted as far as it
will go.
3. Now release the plastic ring. The steel
ball will now hold the tool in place.
4. Check the locking by pulling on the tool. You should be able to move the
tool, but not able to pull it out.
5. To remove the tool, pull back the plastic ring. Now you can pull out the
tool. In the impact drill mode, there will be continuous friction between the
chuck and the tool. It is advisable to grease the shaft of the tool with
machine grease.
