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.
