2. Adjust the rail to the desired position.
3. Tighten the screw at the top at the brace and the screw at the bottom at the pivot joint of the rail.
5.1.6 Extending the rail
Note
When starting a hole, use only a core bit or extended core bit with a maximum total length of 650 mm
(25 1/2 in).
A depth gage on the rail can be used as an additional end stop.
After removing the extension rail, reinstall the cover (with integrated end stop) on the drill stand.
Otherwise the safety-relevant end-stop function is not implemented.
1. Remove the cover (with built-in end stop) from the top end of the rail.
2. Install the cover on the extension rail.
3. Insert the cylindrical connector of the extension rail into the end of the rail of the drill stand.
4. Secure the extension rail by turning the eccentric pin.
5.1.7 Installing the spacer
WARNING
Risk of injury. The fastening may become overloaded.
▶ When one or more spacers are used, the contact pressure must be reduced in order to avoid
overloading the fastening.
Note
When core bits of diameter > 300 mm (11 1/2 in) are used, the distance between drill stand and
drilling axis has to be increased by installing one or two spacers. The hole center indicator is no longer
functional when spacers are used.
Insert the spacer or spacers without the diamond core drilling machine mounted on the drill stand.
1. Lock the carriage on the rail with the carriage lock.
2. Pull out the eccentric pin for locking the diamond core drilling machine on the carriage.
3. Insert the spacer into the carriage.
4. Push the eccentric pin into the carriage until it is seated.
5. Tighten the eccentric pin.
6. Make sure that the spacer is secure.
