3. When drilling overhead, use the retaining clip on the side handle to secure the water collection hose.
5.3 Preparing to drill using the drill stand
WARNING
Risk of injury.
The drill stand may tip over or rotate if inadequately fastened.
▶
Before using the diamond coring machine, fasten the drill stand securely to the working surface
with an anchor or with a vacuum base plate.
▶
Use only anchors of a type suitable for the applicable material and observe the installation
instructions issued by the anchor manufacturer.
▶
Use a vacuum base plate only when the working surface is suitable for fastening the drill stand by
way of the vacuum fastening 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!
Note
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
Note
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.
Note
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.
