2 Safety
2.1 Safety instructions
Basic safety precautions
WARNING! Read all safety instructions and other instructions. Failure to comply with the safety
instructions and instructions can cause serious injuries.
Keep all safety instructions and instructions for future reference.
▶Do not tamper with or modify the fastening tool in any way.
▶Use only items of equipment that are compatible with each other (fastener guide or magazine, piston and
fasteners).
*2253454* 2253454 English 3
▶Check the fastening tool and accessories for damage.
▶Moving parts must be in full working order; make sure that they cannot jam. Keep moving parts oiled.
▶All parts must be correctly installed to ensure faultless operation of the fastening tool. Damaged
parts must be properly repaired or replaced by Hilti Service unless otherwise stated in the operating
instructions.
▶Use only Hilti DX- cartridges, or other suitable cartridges that meet the minimum safety requirements.
→ page 6
▶Do not attempt to drive fasteners into unsuitable base materials, for example material that is too thin, too
hard, or too brittle. Driving a fastener into these materials can cause the fastener to break, splinter the
material or be driven right through. Examples of unsuitable materials are:
▶Weld seams in steel, cast iron, glass, marble, plastic, bronze, brass, copper, insulating material,
hollow brick, ceramic brick, thin sheet metal (< 4 mm) and cellular concrete.
▶Comply with the 'Direct Fastening Technology Manual', the 'Technical Guide' and the operating
instructions of the fastener to be driven.
Requirements to be met by users
▶Only appropriately trained persons who have been duly authorized and informed of the possible hazards
are allowed to operate or service this fastening tool.
▶Wear your personal protective equipment while the tool is in use.
▶Wear suitable eye protection and a hard hat.
▶Wear protective gloves. The fastening tool can get hot in use.
▶Wear ear protectors. The ignition of a propellant charge can damage the hearing.
▶Wear non-skid shoes.
Requirements to be met by the workplace
▶Keep the workplace tidy. Objects which could cause injury should be removed from the working area.
Disorder in the working zone can lead to accidents.
▶Make sure that the working area is well lit and, when working in an enclosed space, make sure it is
adequately ventilated.
Personal safety
▶WARNING! Never press the nosepiece of the fastening tool against your hand or any other part of
the body! Never point the fastening tool toward other persons! → page 7
▶Do not compress the fastening tool with your hand on the magazine, the fastener guide or a loaded
fastener.
▶Compressing the fastening tool by hand can make the fastening tool ready to fire, endangering you
and others.
▶Everyone in the vicinity must wear ear protection, eye protection and a hard hat.
▶Stay alert, watch what you are doing and use common sense when operating a direct fastening tool. Do
not use the fastening tool when you are tired or under the influence of drugs, alcohol or medication. Stop
working if you experience pain or feel unwell. A moment of inattention while operating the fastening tool
can result in serious injury.
▶Avoid working in awkward body positions. Make sure you work from a safe stance and stay in balance
at all times.
▶Keep the arms slightly bent while operating the fastening tool, do not straighten the arms.
▶Keep other people away from the working area, especially children.
Use and care of direct fastening tools
▶Use the fastening tool only for its intended use and only when it is in faultless condition. Do not attempt
to use the tool for purposes for which it is not intended.
▶Do not use the fastening tool in places where there is a risk of fire and explosion.
▶Before driving fasteners, check that there is no electrical wiring, water piping or gas piping behind the
surface into which you want to drive them. For detailed information, request a copy of the 'Direct
Fastening Technology Manual' and the 'Technical Guide' from the local Hilti Store.
▶Before driving fasteners, check behind the object to make sure that no-one is present in line with the
fasteners to be driven. Danger of fasteners penetrating right through!
▶Make sure that the nosepiece of the fastening tool is never pointed toward yourself or other persons.
▶Always use the splinter guard (accessory) for tasks that can produce flying splinters.
▶Hold the fastening tool only by the grip surfaces provided for the purpose.
▶Keep the grip surfaces dry, clean and free from oil and grease.
▶Pull the trigger only when the fastening tool is at right angles to and pressed fully against the work
surface.
4 English 2253454 *2253454*
▶Before starting work, check the selected energy setting.
▶Carry out a test by driving 2 fasteners into the base material you are working on → page 8.
▶When driving fasteners, always hold the fastening tool at right angles to the work surface. This reduces
the risk of a fastener being deflected by the base material.
▶Do not drive fasteners into existing holes unless this is recommended by Hilti (e.g. DX-Kwik).
▶Do not re-use a fastener that was used beforehand - risk of injury! Use a new fastener.
▶Do not attempt to re-drive a fastener that was not driven in deeply enough! The fastener could break.
▶Never leave a loaded fastening tool unattended.
▶Always unload the fastening tool (remove cartridges and fasteners) before cleaning, maintenance,
changing the fastener guide, before work breaks and before storing the tool.
▶Transport and store the fastening tool in the Hilti case intended for the purpose.
▶Store fastening tools that are not in use in a dry, secure place where they are inaccessible to children.
▶Always position the nosepiece of the fastening tool on smooth, flat surfaces free of obstructions and fully
supported by the sub-structure.
▶Comply with the specifications for edge distances and center-to-center distances (see the section
headed 'Minimum distances and edge distances → page 6').
Thermal safety rules
▶Do not exceed the maximum fastener driving rate recommended in the section headed "Technical data".
▶If the fastening tool overheats or if the cartridge strip deforms or melts, remove the cartridge strip and
allow the fastening tool to cool down.
▶Do not dismantle the fastening tool while it is hot. Allow the fastening tool to cool down.
Risk of explosion with cartridges
▶Use only cartridges that are suitable and approved for use with the fastening tool.
▶Remove the cartridge strip when you are going to take a break and when you have finished the job, and
before you transport the fastening tool.
▶Do not use force to remove fasteners and/or cartridges from the magazine strip or the fastening tool.
▶Store unused cartridges in accordance with the storage specifications for PAT cartridges (e.g. dry,
temperature between 5 °C and 25 °C) in a locked storage facility. Follow the instructions for storage in
the safety data sheet of the cartridges.
▶Do not leave unused or partly used cartridge strips lying around. Collect the used cartridge strips and
store the cartridge strips at a suitable location (see also 'Storage of unused cartridges').

3.7 Requirements to be met by cartridges
Use only the Hilti DX cartridges listed in this table, or other suitable cartridges that are compliant with the
minimum safety requirements:
• It is a requirement for EU and EFTA countries that the cartridges must be CE-compliant and must bear
the CE mark of compliance.
• It is a requirement for the USA that the cartridges must be compliant with the stipulations set out in
ANSI A10.3-2020.
• It is a requirement for the non-European member states of the C.I.P. that the cartridge must have C.I.P.
approval for the DX fastening tool used.
• It is a requirement for the remaining countries that the cartridges must have passed the firing-residues
test in accordance with EN 16264 and must have a manufacturer's declaration to this effect.
WARNING! Use of cartridges that do not meet the minimum safety requirements can lead to a build-
up of unburned powder. A sudden explosion and severe injuries to the operator and bystanders can
