Note
When starting holes, use only core bits or extended core bits 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, the cover (with integrated end stop) must be refitted to the drill stand
in order to ensure that the safety-relevant end-stop function is restored. The safety-relevant end-stop
function becomes inoperative if this component is not fitted.

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
The diamond core drilling machine should not already be mounted on the drill stand when the spacer
is being fitted.
Note
When core bits with a diameter of 300 mm (11 1/2 in) or greater are used, the distance between
the drill stand and the drilling axis must be increased by fitting one or two spacers. The hole center
indicator is no longer functional when spacers are used.
