Setting up the saw system for various applications
8. 1 Fastening to the base material
– The saw system can only be used efficiently and safely when it is anchored rigidly and securely to the base
material. We recommend the use of Hilti drilling machines and anchor systems.
– The rail supports and angular cutting plates must be fastened using anchors suitable for the base material.
Observe the installation instructions given by the anchor manufacturer for setting the anchors.
– For example, when placing the Hilti HKD M12 metal expansion anchor, a minimum distance of 18 cm to the
nearest edge must be observed. As a rule, the concrete dust should be blown out of the hole and the anchors
set > 5 mm below the concrete surface.
– On masonry etc., for example, Hilti HIT adhesive anchors or through rods may be used.
– On extremely uneven surfaces, suitable shims or packing pieces must be positioned beneath the rail supports
and / or the rail support adjustment screws adjusted accordingly.
– The most frequently used anchor on reinforced concrete:
