In addition to the safety precautions listed in the individual sections of these operating instructions, the
following points must be strictly observed at all times.
1.2 Only use Hilti cartridges or cartridges of equivalent quality
The use of cartridges of inferior quality in Hilti tools may
lead to build-up of unburned powder, which may explode and cause severe injuries to operators and bystanders. At a minimum, cartridges must either:
a) Be confirmed by their supplier to have been suc-
cessfully tested in accordance with EU standard EN
16264
NOTE:
● All Hilti cartridges for powder-actuated tools have
been tested successfully in accordance with EN 16264.
● The tests defined in the EN 16264 standard are system
tests carried out by the certification authority using
specific combinations of cartridges and tools.
The tool designation, the name of the certification authority and the system test number are printed on the
cartridge packaging.
or
b) Carry the CE conformity mark (mandatory in the EU
as of July 2013).

● Before using the tool, make sure that no one
is standing behind or below the point where fasteners
are to be driven.
● Keep the grip dry, clean and free from oil and grease.
1.7 General safety precautions
● Operate the tool only as directed and only when it is
in faultless condition.
● If a cartridge misfires or fails to ignite, proceed as follows:
1. Keep the tool pressed against the working surface for
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.
● 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
be stored in a place where they are not exposed to humidity or excessive heat. The tool should be transported
and stored in a toolbox that can be locked or secured to
prevent use by unauthorized persons.
1.8 Temperature
● Do not disassemble the tool while it is hot.
● Never exceed the recommended maximum fastener
driving rate (number of fastenings per hour). The tool
may otherwise overheat.
● Should the plastic cartridge strip begin to melt, stop
using the tool immediately and allow it to cool down.

3. Technical description
The tool is designed for professional use in fastening
applications where specially-designed 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.
Piston return and cartridge transport is fully automatic.
This permits fastenings to be made very quickly and
economically with nails and threaded studs. The use of
a nail magazine (MX27 or MX32) 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 achieved 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 is designed to prevent 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 fully depressed.
The contact pressure safety device requires the tool
to be fully depressed with a significant force. The tool
can be fired only when pressed fully 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 쩸 correctly and 쩹 the trigger then
pulled.

Note:
Do not grind the piston. If the piston is made shorter
the tool will be damaged.
8. Care and maintenance
When this type of tool is used under normal operating
conditions, dirt and residues build up inside the tool
and functionally relevant parts are also subject to wear.
Regular inspections and maintenance are thus essential in order to achieve reliable operation. We recommend that the tool is cleaned and the piston and piston
brake are checked at least weekly when the tool is subjected to intensive use, and at the latest after driving
8,000 fasteners.
Care of the tool
The outer casing of the tool is manufactured from impactresistant plastic. The grip comprises a synthetic rubber
section. The ventilation slots must be unobstructed and
kept clean at all times. Do not permit foreign objects to
enter the interior of the tool. Use a slightly damp cloth
to clean the outside of the tool at regular intervals. Do
not use a spray or steam-cleaning system for cleaning.
Maintenance
Check all external parts of the tool for damage at regular intervals and check that all controls operate properly. Do not operate the tool when parts are damaged or
Printed: 12.08.2013 | Doc-Nr: PUB / 5126242 / 000 / 01

24
en
when the controls do not operate properly. If necessary,
have the tool repaired at a Hilti service centre.
Servicing the tool
The tool should be serviced if:
1. Cartridges misfire
2. Fastener driving power is inconsistent
3. If you notice that:
● contact pressure increases,
● trigger force increases,
● power regulation is difficult to adjust (stiff),
● the cartridge strip is difficult to remove.
CAUTION while cleaning the tool:
● Never use grease for maintenance /lubrication of tool
parts. This may strongly affect the functionality of the
tool. Use only Hilti spray or such of equivalent quality.
● Dirt from DX tool contains substances that could be
endangering your health.
– Do not breath in the dust from cleaning
– Keep dust away from food
– Wash your hands after cleaning the tool
