5.2 Securing the drill stand by vacuum
DANGER
Risk of injury if the diamond core drilling machine falls !
▶ Fastening the drill stand to the ceiling only by means of the vacuum securing method is not permissible.
A heavy structural support or a threaded spindle, for example, can serve as an additional means of
fastening.
WARNING
Risk of injury if pressure is not checked !
▶ Before and during drilling, check that the pressure gage pointer remains in the green zone.
In order to use the drill stand with anchor base plate, establish a secure, flat-on-flat connection between
vacuum base plate and anchor base plate. Screw the anchor base plate securely to the vacuum base
plate. Make sure that the core bit selected for use will not damage the vacuum base plate.
If you are going to drill horizontally, use additional means of securing the diamond core drilling machine
(e. g. chain secured to anchor).
Before positioning the drill stand, check that you have sufficient space for assembly and operation.
1. Turn all the leveling screws until they project approx. 5 mm underneath the vacuum base plate.
2. Connect the vacuum connector on the vacuum base plate to the vacuum pump.
3. Locate the center point of the hole to be drilled. Draw a line from the center of the hole to be drilled in
the direction in which the machine is to be positioned.
4. Make a mark on the line at the specified distance from the center of the hole to be drilled.
Distance of marking → page 44
5. Switch on the vacuum pump and press and hold the vacuum release valve.
6. Line up the mark on the base plate with the line.
7. When the drill stand has been positioned correctly, release the vacuum release valve and press the base
plate against the base material.
8. Use the leveling screws to level the base plate.
9. Check that the drill stand is secure.
