SAFTEY FIRST
Requirements to be met by the user
The tool is intended for professional use. The tool may be operated, serviced and maintained only by trained, authorized personnel
who have received special instruction regarding the hazards that may be encountered.
Use the tool for the rst time only after you have been trained by a Hilti specialist on how to use it safely.

Personal safety
Never tamper with or modify the tool in any way.
Do not use the tool for purposes for which it was not intended.
Stay alert, watch what you are doing and use common sense when operating the tool.
Do not use the tool if you are not concentrating.
To reduce the risk of injury use only genuine Hilti accessories and spare parts or those of equivalent quality.
Use only fasteners of a type approved for use with the tool.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Never point the tool toward yourself or other persons.
Never press the nosepiece of the tool against your hand or against any other part of your body (or other persons hand or part of
their body).
Drive the fasteners only into structural steel members. Do not attempt to drive fasteners into other materials or into hardened or
brittle steel, cast iron or spring steel.
Pull the trigger only when the nosepiece of the tool is in contact with the working surface and the tool is fully compressed.
When driving fasteners, always hold the fastening tool at right angles to the working surface in order to help prevent the fastener
being deected by the surface.
Never redrive a fastener, as this may cause the fastener to brake.
Keep the grips dry, clean and free from oil and grease.
Never leave a loaded tool unattended.
Always remove the cartridges before cleaning, servicing or carrying out maintenance work on the tool.
Never leave the tool unattended.
When not in use, the tool should be unloaded (cartridge strips removed) and stored in a locked, dry place where it is inaccessible
to children.
Never compress the tool while operating the Pawl, as this presents a risk of injury to the operators hand.
Remove the cartridge strip from the tool carefully. Never attempt to pry a cartridge from the magazine strip or tool.
Do not disassemble the tool while it is hot. If this is unavoidable, wear protective gloves.
Store unused cartridges in a dry place, where they are locked away or high up and out of reach of children.
Do not operate the tool when parts are damaged or when the controls do not function correctly.
Have the tool repaired by Hilti Tool Service.

Personal Protective Equipment (PPE)
Operator and bystanders must wear helmet, eye and ear protection. Hilti recommends the operator wear hand gloves. In addition, all
the jobsite safety requirements (steel toe safety shoes, safety harness, high visibility vest, etc.), deemed necessary by the local regula-
tions and jobsite requirements must be adhered to.

SELECTING THE RIGHT NAIL, TOOL & CARTRIDGE 7
INDEX
A fastener selection guide is
available to aid in selecting
the right nail if doubtful. It
is included in every DX 9
tool case and can also be
ordered separately.
Selecting the right nail, tool and cartridge is a pre-requisite for good quality fastening.
In addition, improper selection can lead to excessive wear on the DX 9 deck fastening tool.
Select the right nail
X-HSN 24 fastener is used for
fastening deck to bar joist and
light gauge steel structure in
the thickness range 1/8”
(3.2 mm) to 3/8” (9.6 mm).

Select the right tool
For the X-HSN 24 nail you
need to use the DX 9-HSN
or the DX 860-HSN tool.

Select the right nail
X-ENP-19 L15MXR fastener
is used for fastening deck to
structural steel 1/4”(6.4 mm)
to full steel.

Select the right tool
For the X-ENP-19 L15MXR
nail you need to use the DX
9-ENP or the DX 860-ENP
tool.

Select the right cartridge
For the X-ENP-19 L15MXR nail and DX 9-ENP or the DX 860-
ENP tool you need to use the 6.8/18 M40 cartridge.

Select the right cartridge
For the X-HSN 24 nail and the DX 9-HSN or the DX 860-
HSN tool you need to use the 6.8/11 M40 cartridge.

See below reference chart to select the right color cartridge based on steel strength and steel thickness by nail type. The num-
ber within the box provides a quick reference for the tool power level. However, due to variability in base steel, check the nail
stand-off by performing test fastenings and adjust the power level accordingly.

FASTENING METAL DECK TO THE STEEL STRUCTURE 10
INDEX
x1
Mark the deck
Marking the deck is import-
ant to fasten on the joist
or beam because you cant
see the joist or beam when
fastening the deck.

Mark the deck
Marking the deck is import-
ant to fasten on the joist
or beam because you cant
see the joist or beam when
fastening the deck.

Load the nail
It is a good practice to
always keep the Nail
Magazine full. This redu-
ces damage to the Piston
Brake/Stop and subsequent
damage to the Nail Detec-
tion Mechanism
Tip: For DX 9-HSN load 6
nail strips and DX 9-ENP
4 nail strips rst and then
always load nails when
cartridge strip runs out.

Align tool with the
deck marking
Align the tool with the
marking prior to fastening.
Piston jam is a reported
problem by our customers.
In most cases is due to
missing the joist or beam
while making the fastening.
Missing the joist and beam
at the time of fastening can
reduce the lifetime of the
Piston and Piston Brake/
Stop. Hence, it is important
to mark the deck and align
the tool with the mark while
fastening.

Compress the tool and
pull the trigger


UNDERSTANDING THE SERVICE INDICATOR
The Hilti DX 9-HSN / DX 9-ENP tool has an integrated digital Service Indicator. The digital Service
Indicator on the DX 9 gives real-time feedback on when to clean and service the tool, maximizing
productivity on the job. The tools operating temperature range is also displayed, helping you to work
at the optimal pace.
The SI displays prompts and eld what it means and the action required is explained below.
The gauge shows the optimal operating temperature
(i.e. working at optimal installation pace). A warning sign
shows when the tool temperature is extremely high.
A tool wrench is displayed when the tool needs to be
sent to Hilti Tool Service Center for maintenance.
A large cleaning brush is displayed
when the tool requires cleaning.
A progression bar with 7 segments indicates
the number of settings since the last cleaning.
