Preparations at the workplace

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.
5.1 Securing the drill stand with an anchor
WARNING
Risk of injury due to use of wrong anchors! The machine can break loose and cause damage.
▶ Use anchors suitable for the material on which you are working and observe the anchor manufacturer's
instructions.
Hilti metal expansion anchors M12 and M16 are usually suitable for use as anchors for diamond core
drilling equipment in uncracked concrete. Under certain conditions, however, it may be necessary
to use an alternative fastening method. Contact Hilti Technical Service if you have questions about
secure fastening.
1. Set an anchor that is suitable for the base material. Select the distance to suit the base plate used.

2. Screw the anchor spindle into the anchor.
3. Slip the base plate of the diamond core drilling machine over the spindle and align it.
4. Screw the clamping nut on to the spindle but do not tighten it.
5. Use the leveling screws to level the base plate. Make sure that the leveling screws are firmly seated
against the surface.
6. Use a suitable open-end wrench to tighten the clamping nut on the clamping spindle.
7. Make sure that the diamond core drilling machine is secure.
5.2 Securing the drill stand by vacuum
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.
