2. Description
The tool is designed for professional use in fastening
applications where nails, threaded studs and composite
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 piston principle provides an optimum of working and fastening 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. The use of a nail magazine greatly increases the speed and convenience of fastening with the tool, above all when making large numbers of identical fastenings of all kinds.
As with all powder-actuated tools, the tool, magazine,
fastener program 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 recommendations 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
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
driving process ends when the piston reaches the end
of its travel. This makes dangerous through-shots virtually impossible when the tool is used correctly .
The drop-firing safety device is the result of coupling
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 ensures that the cartridge
cannot be fired simply by pulling the trigger only. The
tool can be fired only when pressed against the work
surface.
3
2
The contact pressure safety device requires the tool
to be pressed against the work surface with a significant force. The tool can be fired only when pressed fully against the work surface in this way.
In addition, all Hilti DX tools are equipped with an unintentional firing safety device . This prevents the tool
from firing if the trigger is pulled and the tool then pressed
against the work surface. The tool can be fired only when
it is first pressed (1.) against the work surface correctly and the trigger then pulled (2.).
