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 requirements:
a) The applicable manufacturer must be able to verify
successful testing in accordance with the EU standard 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 designation, the name of the certification authority and the system
test number are printed on the cartridge packaging.

Never leave a loaded tool unattended.
Store unused cartridges and tools currently not in
use in a dry place where they are not exposed to
high temperatures.
Transport and store the tool in a toolbox that can be
secured to prevent unauthorized use.
Always unload the tool (remove cartridges and
fasteners) before cleaning, before maintenance,
before work breaks and before storing the tool.
When not in use, tools must be unloaded and
stored in a dry place, locked up or out of reach of
children.
Check the tool and its accessories for any damage. 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 sticking and that no parts are damaged. All parts must
be fitted correctly and fulfill all conditions necessary 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 operating instructions.
Pull the trigger only when the tool is fully pressed

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.
Driving a fastener into these materials may cause
the fastener to break, shatter or to be driven right
through.
d) Never attempt to drive fasteners into materials
such as glass, marble, plastic, bronze, brass,
copper, rock, insulation material, hollow brick,
ceramic brick, thin sheet metal (< 4 mm), cast
iron or cellular concrete.
e) Before driving fasteners, check that no one is
present immediately behind or below the working
surface.
f) Keep the workplace tidy. Objects which could
cause injury should be removed from the working area. Untidiness at the workplace can lead to
accidents.
g) Keep the grips dry, clean and free from oil and
grease.
h) Do not use the tool where there is a risk of fire or
explosion unless it has been specially approved
for use under these conditions.

3 Description
3.1 Use of the product as directed
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 is for hand-held use only.
Modification of the tool is not permissible.
The tool may not be used in an explosive or flammable atmosphere unless it has been approved for use under these
conditions.
To avoid the risk of injury use only genuine Hilti fasteners, cartridges, accessories and spare parts or those of
equivalent quality.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
19
Printed: 14.04.2014 | Doc-Nr: PUB / 5125972 / 000 / 02
en
The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used
not as directed.
The tool may be operated, serviced and repaired only by trained personnel. This personnel must be informed of any
special hazards that may be encountered.
As with all powder-actuated fastening tools, the tool, cartridges and fasteners form a technical unit. This means that
trouble-free fastening with this system can be assured only if the Hilti 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 features a 5-way safety system for the safety of the user and all bystanders.
3.2 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. Due to use of this piston principle, the tool is classified as a “low velocity tool”. As approximately
95% of the kinetic energy is absorbed by the piston, the fastener is driven into the base material in a controlled fashion
at much reduced velocity (less than 100 m/s). The driving process ends when the piston is stopped at the end of its
travel. This makes dangerous through-shots virtually impossible when the tool is used correctly.
3.3 Drop-firing safety device
The drop-firing safety device is the result of coupling the firing mechanism with the cocking movement. This prevents
the tool from 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 must be pressed against a
firm surface before a fastener can be released.
3.5 Contact pressure safety device
The tool can be fired only when pressed fully against a firm surface with a force of at least 50 N.
3.6 Unintentional firing safety device
The tool is also equipped with an unintentional firing safety device. This prevents the tool from firing if the trigger is first
pulled and the tool then pressed against the work surface. The tool can be fired only when it is first pressed correctly
against the work surface and the trigger subsequently pulled.

8 Operation
WARNING
Never redrive a fastener. This may cause the fastener
to break and the tool may jam.
WARNING
Driving a fastener may cause flying fragments. The user
of the tool and bystanders must wear protective
glasses and a hard hat. Flying fragments present a
risk of injury to the eyes and body.
CAUTION
The fastener driving action is initiated by ignition of a
propellant charge. The operator and bystanders must
wear ear protectors. Exposure to noise can cause hearing loss.
WARNING
Never make the tool ready to fire by pressing it against a
part of the body (e.g. the hand). This could cause a nail
or the piston to be driven into a part of the body. Never
press the tool against a part of the body.
WARNING
Never drive fasteners into existing holes unless this
is recommended by Hilti (e.g. DX‑Kwik).
CAUTION
If the tool has overheated, allow it to cool down. Do
not exceed the recommended fastener driving rate.
8.1 Procedure if a cartridge fails to fire
If a cartridge fails to fire or misfires, always proceed as
follows:
Keep the nose of the tool pressed at right angles against
the working surface for 30 seconds.
If the cartridge still fails to fire, withdraw the tool from the
working surface, taking care to avoid pointing it toward
your body or toward bystanders.
23
Printed: 14.04.2014 | Doc-Nr: PUB / 5125972 / 000 / 02

tool as far as it will go.
Insert an unused cartridge in the cartridge chamber.
NOTE Insert the cartridge in the tool gently. Do not
press it in!
Then pull the fastener guide all the way back to its
original position.
This movement returns the piston to its original
position, ready to drive a fastener.
Push the nail, head first, into the nose of the tool
from the front until it is held in place in the tool by
the washer on the nail.
NOTE If the cycling action (i.e. pulling out, pushing
back in) is stiff, this indicates that the tool needs to
be cleaned. Service the tool! see section 9.3
The tool is then ready to drive the next fastener.
8.3 Setting the power level
1.
Select the cartridge power level according to the
application to be carried out.

As soon as you have finished the work, check to ensure
that there is no cartridge or nail in the tool. If the tool is
still loaded after finishing the work, remove the cartridge
and the nail from the tool.
NOTE
If a cartridge case remains stuck in the cartridge chamber,
disassemble the tool as described in section 9.3.1 and
use the ramrod to push the cartridge case out of the
cartridge chamber from the front.
9 Care and maintenance
9.1 Care of the tool
CAUTION
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 ensure reliable operation. We recommend
that the tool is cleaned and the condition of the piston checked at least daily when the tool is subjected
to intensive use, and at the latest after driving 3,000
fasteners.
WARNING
Make sure there is no cartridge in the tool before
carrying out maintenance or repairs. Make sure there
is no fastener in the fastener guide.
CAUTION
The tool may get hot during use. You could burn your
hands. Do not dismantle the tool while it is hot. Allow
the tool to cool down.
24
Printed: 14.04.2014 | Doc-Nr: PUB / 5125972 / 000 / 02
WARNING

slots are blocked. Do not permit foreign objects to
enter the interior of the tool.
Clean the outside of the tool at regular intervals with a
slightly damp cloth.
9.2 Maintenance
Check all external parts of the tool for damage at regular
intervals and check that all controls operate faultlessly.
Do not operate the tool if parts are damaged or when the
controls do not function faultlessly. If necessary, the tool
should be repaired by Hilti Service.
Use the tool only with the recommended cartridges. Use
of the wrong cartridges or use of excessively high power
settings may lead to premature failure of parts of the tool.
WARNING
Dirt and residues in DX tools contain substances that
may be hazardous to your health. Do not inhale dust /
or dirt from cleaning. Keep the dust or dirt away from
foodstuffs. Wash your hands after cleaning the tool.
Never use grease for the maintenance/lubrication of
parts of the tool. This may lead to malfunctions. Use
only Hilti lubricant spray or a product of equivalent
quality.
9.3 Servicing the tool
Service the tool if fastener driving power is found to be
inconsistent, if cartridges misfire or if parts of the tool
no longer move or operate smoothly and easily. In other
words, the contact pressure required to make the tool
ready to fire increases, trigger resistance increases, used
cartridges are difficult to remove or the cycling action
becomes stiff.
9.3.1 Disassembling the tool 8 9 10 11
NOTE

with or attempt to modify the piston.
NOTE
Replace the stop ring if it is deformed or damaged.
CAUTION
Continued use of the tool with a deformed stop ring
may result in damage to the fastener guide and piston.
Replace the piston if:
- the piston is broken
- the piston is badly worn or chipped (e.g. a 90° segment
broken away).
- the piston ring is cracked or missing.
- the piston is bent (check by rolling the piston on a
smooth, flat surface).
9.3.3 Checking the fastener guide for wear
Replace the fastener guide if the tubular section is damaged (e.g. bent, widened or cracked).
9.3.4 Checking the O-ring for damage or wear
Replace the O-ring if it is cracked, badly squashed or
missing.
9.3.5 Cleaning 12 13 14 15
CAUTION
Take care to avoid damaging the O-ring with the
brush.
Clean the tool at least once a week or, respectively,
immediately after each period of heavy use (after driving
approx. 3,000 nails).
Use the appropriate brushes to clean the individual parts:
- clean the inside of the housing
- clean the piston guide and the cartridge chamber
- clean the inside and the outside of the fastener guide
Clean the piston and the piston ring until it moves freely.
9.3.6 Lubrication
Spray the cleaned parts lightly with the Hilti lubricant
spray supplied. Use only Hilti lubricant spray or a product
of comparable quality.
