5.3 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 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 suitable for the base material at a distance of 203 mm (8 in) from where the center point
of the drillhole will be.
2. Screw the clamping spindle into the anchor.
3. Back off all leveling screws until the base plate is flush with the surface.
4. Slip the drill stand over the clamping spindle and align the drill stand.
5. Screw the clamping spindle nut on to the clamping spindle but do not tighten it.
6. Level the base plate by turning the 4 leveling screws.
All leveling screws make be seated firmly on the surface.
7. Secure the drill stand by tightening the clamping spindle nut with a 19 mm open-ended wrench.(SW 19)

Fastening the drill stand with the vacuum base plate (accessory)

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.
Make sure that the core bit selected for use will not damage the vacuum base plate.
Before positioning the drill stand, check that you have sufficient space for assembly and operation.
Use the vacuum fastening method only together with core bits ≤ 300 mm (≤ 12 in) in diameter and
when no spacer is fitted.
1. From the center point of the hole to be drilled, draw an orientation line approx. 800 mm (31.5 in) toward
and past where the diamond core drilling machine will be positioned.
