3. Description

The tool is designed for professional use in fastening
applications where nails, threaded studs and compo site
fasteners are driven into concrete, steel and sand-lime
block masonry.
The tool works on the well-proven piston principle and
is therefore not related to high-velocity tools. The pis-
ton principle provides an optimum of working and fas-
tening safety. The tool works with cartridges of 6.8/11
caliber.
The piston is returned to the starting position and the
cartridges are fed to the firing chamber automatically
by gas pressure from the fired cartridge. This permits
fastenings to be made very quickly and economically
with nails and threaded studs.
As with all powder-actuated tools, the tool, fastener pro-
gram and cartridge program form a "technical unit".
This means that optimal fastening with this system can
only be assured if the fasteners and cartridges are
specially manufactured for it, or products of equivalent
quality, are used. The fastening and application recom-
mendations given by Hilti are only applicable if these
conditions are observed.
The tool features 5-way safety – for the safety of the
operator and bystanders.
The piston principle
1
The energy from the propellant charge is transferred to
a piston, the accelerated mass of which drives the fastener
into the base material. As approximately 95 % of the
kinetic energy is absorbed by the piston, the fastener is
driven into the base material at much reduced velocity
(less than 100 m/sec.) in a controlled manner. The dri-
ving process ends when the piston reaches the end of
its travel. This makes dangerous through-shots virtual-
ly impossible when the tool is used correctly.
The drop-firing safety device
the firing mechanism with the cocking movement. This
prevents the Hilti DX tool from firing when it is dropped
onto a hard surface, no matter at which angle the impact
occurs.
The trigger safety device
cannot be fired simply by pulling the trigger only. The
tool can be fired only when pressed against the work
surface.
The contact pressure safety device
to be pressed against the work surface with a signifi-
is the result of coupling
