5.3 Preparing to drill using the drill stand
WARNING
Risk of injury! The drill stand can rotate or topple if not securely fastened.
▶ Before using the diamond core drilling machine, secure the drill stand to the work surface with anchors
or with a vacuum base plate.
▶ Use only anchors suitable for the base material and comply with the anchor manufacturer's instructions.
▶ Use a vacuum base plate only when the work surface is suitable for securing the drill stand by the
vacuum method.
The drill stand and the machine can be fastened either using the vacuum base plate or the DD M12 S
accessory set, i.e. using an HKD-D M12x50 anchor, the DD-LR-CLS clamping spindle and the DD-LR-CLN
nut.
WARNING
Water running out presents a risk of electric shock! The spray guard cannot be used when the machine
is mounted on the drill stand. The machine is therefore not protected against entry of water when mounted
on the drill stand.
▶ Never drill in an upwards direction with the machine mounted on the drill stand!
The side handle and spray guard (if fitted) must be removed before using the machine on the drill stand.
