WARNING
Use an anchor suitable for the material on which you
are working and observe the anchor manufacturer’s
instructions.
NOTE
Hilti M12 metal expansion anchors are usually suita-
ble 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.
Your Hilti representative will be pleased to provide advice

The position of the through-holes has a direct influence
on the accuracy of the cut. We therefore recommend use
of a diamond core drilling rig for drilling though thick
walls or where only low tolerances are permissible.
Hammer drills may be used on thinner walls or where
the permissible tolerances are greater.
We recommend drilling holes of 16 mm diameter. Hole
diameter, however, must be at least approx. 4% of the
wall thickness.
NOTE
In very thick structures, a slightly tapered cut makes it
easier to remove the part that has been cut out..
Securing the base plate
To ensure efficient and safe operation it is essential that
the saw and, where applicable, the pulley stands are fas-
tened correctly and securely using fasteners of adequate
size.
In applications where the compact wire saw is mount-
ed directly on the object where the cut is to be made, the
exact position of the anchor hole and alignment of the
base plate for an accurate cut can be determined with
the aid of the positioning template.
