Dispensing scale on the cartridge label: The dispensing scale units described in the instructions for use refer to piston
move ment relative to the scale on the cartridge label.
Dispenser: Robustly constructed dispensers of the type used for silicone sealants may be used. Poor-quality dis-
pensers may not be able to dispense the product correctly and/or wear out quickly. We recommend use of the Hilti
MD 300 dispenser.
The cartridge opens automatically when dispensing begins. Do not, under any circumstances, cut, saw or pierce the
cartridge (this will have a seriously negative effect on the hardening of the product).
Stainless steel anchors (HAS-R, HIS-RN) must be used for outdoor applications.
Installation instructions: Illustration of the sequence of operations: see pictograms 1–12.
Detailed setting data for hollow materials: see table 1; Solid materials: see tables 2–4.

(with cavities). Use of a diamond coring machine to drill the hole is not permissible.
– If the material is solid, the hole must be cleaned immediately before setting the anchor: Blow out twice, brush
out twice with steel wire brush, blow out twice. The holes must be free from dust, water, ice, oil/grease or
other foreign substances. Inadequate hole cleaning = poor loadbearing capacity
