2 Description
2.1 Use of the product as directed
The product is a hand-held, battery-actuated fastening tool for indoor use. It is designed to drive specially-
manufactured 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 be used to fasten electric cables, so long as fasteners suitable
for this purpose are used. Use only approved fasteners in conjunction with the fastener guide designed for use with
these specific fasteners (see "Technical data" section).
The fastening tool, battery and fasteners form a single technical unit. This means that trouble-free fastening operation
can be ensured with this fastening tool only when it is used in conjunction with the Hilti fasteners specially designed
and manufactured for it and with the batteries and chargers recommended by Hilti. The fastening and application
recommendations given 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 up for magazine operation, and driving nails into materials that are too hard (e.g. high-strength steel or
very hard natural stone).
The tool is designed for professional use and may be operated, serviced and maintained only by trained, authorized
personnel. This personnel must be informed of any special hazards that may be encountered. The tool and its ancillary
equipment may present hazards when used incorrectly by untrained personnel or when used not as directed.
To help avoid the risk of injury, use genuine Hilti accessories and tools.
Observe the national health and safety requirements.
2.2 Safety devices
When using the nail magazine, the nail detection feature prevents triggering without a nail loaded, which could damage
the fastening tool.
The contact pressure safety device prevents nail free-flighting (i.e. actuation and driving a nail when the nosepiece
is not in contact with the workpiece). When using a nail magazine, the tool can be pressed against the surface and
triggered only when a nail is loaded in the tool. In single-fastener driving mode, the fastening tool can be pressed
against the surface only when the single-fastener mode switch has been pressed.
2.3 Features
The fastening tool is equipped with an ergonomic, non-slip, vibration-absorbing grip, a support leg with scaffold hook
as well as overload protection and temperature monitoring systems.
