3.1 Product overview
3.2 Intended use
The product is a hand-held, cordless fastening tool for indoor use. It is designed to drive specially
manufactured fasteners (nails) 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 Hilti fasteners and 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 of the fastening tool must be ruled out. Misuse of the fastening tool includes triggering in
single-fastener mode without a nail inserted in the fastener guide, driving nails into very soft materials
(e.g. wood), driving single nails when the tool is set to magazine operation, and driving nails into materials
that are too hard (e.g. high-strength steel or very hard natural stone).
▶ Use only Hilti Li­ion batteries of the B 22 series with this product.
▶ Use only Hilti battery chargers of the C 4/36 series to charge these batteries.
3.3 Safety devices
In magazine mode, 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). In magazine mode, the fastening tool can
be pressed against the surface and triggered only when a nail is loaded in the tool.
