3.2 Intended use
The product is a hand-held, cordless fastening tool. It is designed to drive specially manufactured fasteners
into concrete, steel, masonry, sand-lime block and other materials suitable for use of the direct fastening
technique. The product is also designed to fasten electrical cables with clips if the appropriate fasteners are
used. Use only approved fasteners in combination with their corresponding fastener guide (see the section
headed "Technical data").
The fastening tool, battery and fasteners together form a technical entity. This means that trouble-free
fastening with this fastening tool can be ensured only when the fasteners specially manufactured for the
purpose by Hilti and the chargers and batteries recommended by Hilti are used. The fastening and
application recommendations made by Hilti apply only when these conditions are observed.
▶ The fastening tool is for hand-held use only.
▶ Misuse must be ruled out. Misuse is understood to include driving fasteners into very soft materials (e.g.
wood) or into excessively hard materials (e.g. high-strength steel or very hard natural stone).
• For this product, use only Hilti Nuron lithium-ion batteries of the B 22 series. For optimum performance,
Hilti recommends the batteries stated in the table at the end of these operating instructions for this
product.
• For these batteries, use only Hilti chargers of the type series stated in the table at the end of these
operating instructions.
3.3 Safety devices
When using the nail magazine, the nail detector prevents triggering without a nail loaded, which could
damage the fastening tool.
The contact pressure safety device is intended to prevent the free flighting of nails (i.e. actuation and driving
a nail when the nosepiece is not in contact with the workpiece). When using a nail magazine, the fastening
tool can be pressed against the surface and triggered only when a nail is loaded in the tool.
3.4 Features
The fastening tool is equipped with an ergonomic, non-slip and vibration-absorbing grip, a belt and scaffold
hook and a support leg. The fastening tool is protected against overload by electronic overload protection
and from overheating by temperature monitoring.
