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.
5.3.1 Fitting the water collector holder
Drilling is permissible only under the following conditions:
The supplied water collector holder is fitted and adjusted to match the length of the core bit used.
A core bit sealing ring that matches the diameter of the core bit must be fitted in the water collector
holder.
1. Unplug the supply cord from the power outlet.
2. Push the water collector holder into the opening provided at the front of the machine until it engages with
a click.
3. Use the slider to set the correct length range for the core bit used. Set the slider to the 150 position for
core bits with a length of up to 150 mm and set it to 300 for core bits with a length of 300 mm or 600 mm.
5.3.2 Fastening the machine and drill stand with the vacuum base plate
WARNING
Risk of injury Hazard presented by a falling diamond core drilling machine.
▶ When drilling horizontally, the drill stand must be secured additionally by a chain.
5.3.2.1 Positioning the vacuum base plate
1. Mark the center of the hole to be drilled with a cross. The lines of the cross should be longer than the
diameter of the water collector.
The water collector has four protruding marks that can be aligned with the cross.
2. Turn the 4 leveling screws on the vacuum base plate until they project approx. 5 mm below the underside
of the vacuum base plate.
3. Position the vacuum base plate at a distance of 21 cm from the hole center.
4. Connect the vacuum connector on the vacuum base plate to the vacuum pump.
5. Switch on the vacuum pump.
6. Keep the vacuum release valve pressed in while correcting the position of the vacuum base plate.

5.3.2.2 Fastening the drill stand on the vacuum base plate

1. Switch on the vacuum pump.
2. Use the clamping spindle to fasten the drill stand on the vacuum base plate.
3. Level the drill stand by turning the two leveling screws.
