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 fastening tools and items of equipment that are compatible with each other (base plates,
fastener guides, magazines, pistons and fasteners) and consumables (fasteners and cartridges).
▶ Check the fastening tool and accessories for damage.
▶ Moving parts must be in full working order; make sure that they cannot jam. Comply with the
instructions on cleaning and oiling in these operating instructions → page 29.
▶ 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 22
▶ Use the fastening tool only for the applications defined in the section headed "Intended use" → page 21.
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 Hilti 'Direct Fastening Technology Manual' or the corresponding regional Hilti
'Technical Guide to Fastening Technology'. Always also comply with the operating instructions of the
fastener to be used.
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
▶ 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 25
▶ Do not compress the fastening tool with your hand on the magazine or fastener guide, piston or piston
guide or a loaded fastener. Compressing the fastening tool by hand can make the fastening tool
ready to fire, even without a fastener guide installed. This gives rise to a risk of serious injury for
yourself 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
