6.1.3 Fastening the drill stand with an anchor 5 6
WARNING
Use an anchor suitable for the material on which you
are working and observe the anchor manufacturer's
instructions.
NOTE
Hilti M16 metal expansion anchors are usually suitable for
fastening diamond core drilling equipment to uncracked
concrete. Under certain conditions it may be necessary
to use an alternative fastening method. Please contact
Hilti Technical Service if you have any questions about
secure fastening.
1. If using the anchor base plate, set an anchor suitable
for the applicable base material at a distance (ideally)
of 267 mm (10 ½ ") from the center of the hole to be
drilled or, if using the combination base plate, at a
distance of 292 mm (11 ½ ") from the hole center.
2. Screw the clamping spindle into the anchor.
3. Place the drill stand base plate over the spindle and
align it.
4. Screw the clamping nut onto the spindle but do not
tighten it.
5. Level the base plate by turning the four leveling
screws. Take care to ensure that the leveling screws
make firm contact with the underlying surface.
6. Use a suitable open-end wrench to tighten the
clamping nut on the clamping spindle.
7. Make sure that the drilling system is secured reliably.
