30 seconds.
2. If the cartridge still fails to fire, withdraw the tool from
the working surface, taking care that it is not pointed
towards your body or bystanders.
3. Manually advance the cartridge strip one cartridge.
Use up the remaining cartridges on the strip. Remove
the used cartridge strip and dispose of it in such a
way that it can be neither reused nor misused.
● If 2–3 cartridge misfires occur in succession (with-
out clearly audible noise of the cartridge firing and the
fastener being driven with significantly less power), proceed as follows:
1. Stop using the tool immediately.
2. Unload and disassemble the tool (see 8.3).
3. Check that the correct combination of fastener guide,
piston and fastener are used (see 6.2).
4. Check the buffer, piston and fastener guide for wear
and replace the parts if necessary (See 6.3 and 8.4).
5. Clean the tool.
6. Do not continue to use the tool if the problem persists after carrying out the steps described above.
Have the tool checked and repaired if necessary at a
Hilti repair center.
● Never attempt to pry a cartridge from the magazine
strip or the tool.
● Keep the arms flexed when the tool is fired (do not
straighten the arms).
● Never leave the loaded tool unattended.
● Always unload the tool before beginning cleaning,
servicing or changing parts and before storage.
● Unused cartridges and tools not presently in use must

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 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.
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.
The contact pressure safety device requires the tool
to be pressed against the work surface with a signifi-

cant 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.).
