2.1 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.
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.
For optimum results and maximum reliability we recommend use of Hilti cartridges or products of equivalent quality.
The following also applies in EU and EFTA countries: For maximum safety with this tool, the cartridges must comply
with the requirements of the applicable C.I.P. tests (source: Comprehensive edition of adopted C.I.P. decisions, Liège,
Belgium, 2005) as well as the cartridge tests described at www.hilti.com/cartridgetest.
The tool features a 5-way safety system for the safety of the user and all bystanders.
2.2 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.
2.3 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 angletheimpactoccurs.
2.4 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.
en
18
Printed: 07.07.2013 | Doc-Nr: PUB / 5125956 / 000 / 00

2.5 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.
2.6 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.

5 Safety instructions
5.1 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.
5.1.1 Requirements to be met by users
a) The tool is intended for professional use.
b) The tool may be operated, serviced and repaired
only by authorized, trained personnel. This per-
sonnel must be informed of any special hazards
that may be encountered.
5.1.2 Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a direct fastening
tool. Don’t use the tool when you are tired or under
the influence of drugs, alcohol or medication. Stop
using the tool if you experience pain or do not feel
well. A moment of inattention while operating the
tool 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.
c) Wear non-skid shoes.
d) Never point the tool toward yourself or other per-
sons.
e) Never press the nosepiece of the tool against your
hand or against any other part of your body (or
other person’s hand or part of their body).
f) Keep other persons, especially children, away
from the area in which the work is being carried
out.
g) Keep the arms slightly bent while operating the
tool (do not straighten the arms).
h) Observe the information printed in the operating in-
structions concerning operation, care and mainten-
ance.
5.1.3 Use and care of powder-actuated fastening
tools
a) Use the right tool for the job. Do not use the tool
for purposes for which it was not intended. Use it
only as directed and when in faultless condition.
b) Never leave a loaded tool unattended.
c) Store unused cartridges and tools currently not in
use in a dry place where they are not exposed to
high temperatures.
d) Transport and store the tool in a toolbox that can be
secured to prevent unauthorized use.
e) Always unload the tool (remove cartridges and
fasteners) before cleaning, before maintenance,
before work breaks and before storing the tool.
f) When not in use, tools must be unloaded and
stored in a dry place, locked up or out of reach of
children.
g) 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 partsfunction 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.
h) Pull the trigger only when the tool is fully pressed
against the working surface at right angles.
i) 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.
j) Never redrive a fastener. This may cause the
fastener to break and the tool may jam.
k) Never drive fasteners into existing holes unless
this is recommended by Hilti.
l) Always observe the application guidelines.
m) Use the fragmentation guard (stabilizer) whenever
allowed by the application.
n) Never pull the fastener guide back by hand as
this could make the tool ready to fire. This could
cause a fastener or the piston to be driven into a
part of the body.
5.1.4 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.
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 work-
ing area. Untidiness at the workplace can lead to
accidents.
g) Keep the grips dry, clean and free from oil and
grease.

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 hear-
ing loss.

WARNING
Never redrive a fastener. This may cause the fastener
to break and the tool may jam.
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.
Remove the cartridge and dispose of it appropriately, i.e.
in a way that rules out further use or misuse.
8.2 Loading the tool 2345
The tool must be cycled and loaded before driving each
fastener.
1. Grip the fastener guide between the thumb and
forefinger and pull it forward in the main axis of the
tool as far as it will go.
2. Insert an unused cartridge in the cartridge chamber.
NOTE Insert the cartridge in the tool gently. Do not
press it in!
3. 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.
4. 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.
2. If you cannot estimate this on the basis of previous
experience, always begin with the lowest power.
Select the lowest power level according to the color
code.
3. Drive a nail.
If the nail does not penetrate deeply enough, use a
more powerful cartridge.
8.4 Driving a fastener 6
WARNING
Always observe the safety rules listed in the operating
instructions.
1. Press the tool against the working surface at right
angles.
2. Drive the fastener by pulling the trigger.
8.5 Unloading the tool 7
WARNING
Never attempt to remove a cartridge from the cart-
ridge chamber by prying it out from behind with a
pointed or sharp object.
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
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. Reg-
ular inspections and maintenance are thus essential
in order to ensure reliable operation. We recommend
that the tool is cleaned and the condition of the pis-
ton 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.

9.1 Care of the tool
WARNING
Do not use a spray or steam/water jet system for
cleaning. Never operate the tool when the ventilation
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 89
NOTE
If the tool is badly fouled, push the piston out of the piston
guide by pushing it from behind, through the cartridge
chamber. Use the ramrod for this purpose.
1. Press the catch fully and, at the same time, pull the
assembly vertically right out of the tool.
2. Tap the assembly lightly on the floor to bring the
piston forward.
3. Hold the fastener guide securely with one hand
and turn the piston guide counterclockwise with the
other hand.
4. Remove the stop ring and pull the piston out.
9.3.2 Checking the piston and stop ring for damage
or wear
NOTE
Never use a worn or damaged piston and do not tamper
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 fastenerguide 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 dam-
aged (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    
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.
9.3.7 Assembling the tool   
