1.1 Basic information concerning safety
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
1.1.1 Using cartridges
Use only Hilti cartridges or cartridges of equivalent
quality.
Use of cartridges of inferior quality in Hilti tools may lead
to a build-up of unburned powder, which may explode
and cause sever injuries to operators and bystanders.
Cartridges must fulfill one of the following minimum re-
quirements:
a) The applicable manufacturer must be able to verify
successful testing in accordance with the EU stan-
dard EN 16264 or
b) The cartridges must bear the CE conformity mark
(mandatory in the EU as of July 2013).
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 designa-
tion, the name of the certification authority and the system
test number are printed on the cartridge packaging.
Please refer to the packaging example at:
www.hilti.com/dx-cartridges
1.1.2 Requirements to be met by users
Never attempt to use the tool without first receiving
proper instruction on its use and observance of the
associated safety precautions.Contact your local Hilti
representative for assistance.
1.1.3 Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a direct fastening
tool. Do not use tool while tired or under the influ-
ence of drugs, alcohol or medication. Amomentof
inattention while operating tools may result in serious
personal injury.
b) Avoid unfavorable body positions. Make sure you
work from a safe stance and stay in balance at all
times.

the grip provided. Do not hold the exposed metal
pole of the extensions. This may cause the tool to
malfunction.
c) Press the tool against the working surface at right
angles.
d) Never leave a loaded tool unattended.
e) Always unload the tool (remove cartridges and
fasteners) before cleaning, before maintenance,
before work breaks and before storing the tool.
f) Check the tool and its accessories for any dam-
age. Guards, safety devices and any slightly worn
parts must be checked carefully to ensure that
they function faultlessly and as intended. Check
that moving parts function correctly without stick-
ing and that no parts are damaged. All parts must
be fitted correctly and fulfill all conditions neces-
sary for correct operation of the tool. Damaged
guards, safety devices and other parts must be
repaired or replaced properly at a Hilti service
center unless otherwise indicated in the operat-
ing instructions.
g) Always hold the tool securely and at right angles
to the working surface when driving in fasteners.
This will help to prevent fasteners being deflected
by the working surface.
h) Never use a fastener twice.
i) Never redrive a fastener. This may cause the fas-
tener to break and the tool may jam.
j) Never drive fasteners into existing holes unless
this is recommended by Hilti.
k) Always observe the application guidelines, in-
cluding the minimum thickness of the base ma-
terial, fastener spacing and the minimum edge
distances.
l) Use the spall guard when the application permits.
m) Never pull the fastener guide back by hand as
this could, under certain circumstances, make
the tool ready to fire. This could cause a fastener
or the piston to be driven into a part of the body.
n) Donotdismantlethetoolwhileitishot.
o) The applicable national regulations, especially
those concerning accident prevention, must be
observed.
1.1.5 Work area safety
a) Ensure that the workplace is well lit.
b) Operate the tool only in well-ventilated working
areas.
c) Do not attempt to drive fasteners into unsuitable
materials. Materials that are too hard, e.g. welded
steel and cast iron. Materials that are too soft, e.g.
wood and drywall panel (gypsum board). Materials
that are too brittle, e.g. glass and ceramic tiles. Other
unsuitable materials include: Glass, marble, plastic,
bronze, brass, copper, rock, insulating material, hol-
low brick, ceramic tiles, thin sheet metal (< 4 mm)
and cellular concrete. Driving a fastener into these
materials may cause the fastener to break, shatter or
to be driven right through.
d) Do not use the tool on surfaces with a fire pro-
tection coating thicker than 12 mm (½").
Using the
tool on surfaces with a fire protection coating may
cause the tool to malfunction.
e) Before driving fasteners, check that no one is
present immediately behind the working surface.
f) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
g) Keep the grip section and grip clean, dry and free
from oil and grease.
h) Wear non-skid shoes.
i) Take the influences of the surrounding area into
account. Do not expose the tool to rain or snow.
Do not use the tool where there is a risk of fire or
explosion.
1.1.6 Mechanical safety precautions
a) Select the correct fastener guide and fastener
combination for the job on hand. Failure to use
the correct combination of these items may result
in injury or cause damage to the tool and/or lead to
unsatisfactory fastening quality.
b) Use only fasteners of a type approved for use with
the tool.
c) Do not use a worn or damaged piston or piston
brake. Do not tamper with or modify the piston.
1.1.7 Thermal safety precautions
a) If the tool has overheated, allow it to cool down.

3 Description
3.1 Use of the product as directed
The Hilti DX 351‑CT is a powder-actuated tool designed
for driving nails into concrete, steel and other materi-
als suitable for DX fastening (see Fastening Technology
Manual).
The tool utilizes a captive piston to provide optimum
functional reliability and working safety. The tool features
automatic piston return and cartridge transport powered
by gas pressure resulting from operation of the tool. Nails
of up to 37 mm in length can thus be driven very quickly
and efficiently.
As with all powder-actuated fastening tools, the tool, the
fastener guide, the grip, the fasteners and the cartridges
form a single “technical unit”. This means that trouble-
free fastening with this system can be assured only if
fasteners and cartridges specially manufactured for it, or
products of equivalent quality, are used. The fastening
and application recommendations given by Hilti apply
only when these conditions are observed.
The tool is designed for professional use and may be
operated, serviced and maintained only by trained, au-
thorized 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 avoid the risk of injury use only genuine Hilti fasten-
ers, cartridges, accessories and spare parts or those of
equivalent quality.
Modification of the tool is not permissible.
3.2 Through-shot and ricochet safety device
As a result of the piston principle, the DX 351-CT is
classified as a low-velocity tool. Most excess driving
energy is dissipated inside the tool.
3.3 Drop-firing safety device
The drop-firing safety device is the result of coupling the
firing mechanism with the cocking movement. This helps
prevent the tool firing when dropped onto a hard surface,
no matter at which angle the impact occurs.
3.4 Trigger safety device
The trigger safety device prevents the tool firing when
only the trigger is pulled. The tool can be fired only when
it is pushed fully against the working surface, pointing
upwards, and the grip pressed.
3.5 Contact pressure safety device
The contact pressure safety device prevents the tool firing
unless it is firmly pressed against a surface. The tool can
be fired only when pressed fully against a surface with a
force of at least 140 N.
3.6 Gravitation safety device
The gravitation safety device prevents the tool firing when
in a horizontal position or when pointing toward the floor.
The tool can be fired only when it is pointing upwards.
