Personal protective equipment
▶ You and all other persons in the vicinity must wear suitable eye protection and a hard hat while the tool
is in use.
▶ Wear hearing protection.
➥ Exposure to noise can cause hearing loss.
Personal safety
▶ Observe the information printed in the operating instructions concerning operation, care and maintenance.
▶ Stay alert, watch what you are doing and use common sense when operating a direct fastening tool. Do
not use the tool when you are tired or under the influence of drugs, alcohol or medication. Take a break
if you experience pain or feel unwell. A moment of inattention while operating tools may result in serious
personal injury.
▶ Avoid awkward postures. Make sure you work from a safe stance and stay in balance at all times.
▶ Take breaks between working and do relaxation and finger exercises to improve the blood circulation in
your fingers.
▶ Wear non-skid shoes.
▶ Keep the arms slightly bent while operating the tool (do not straighten the arms).
▶ Keep other people away from the working area, especially children.
Use and care of direct fastening tools
WARNING! Danger of threaded studs penetrating right through! Before driving threaded studs, check
to make sure that no one is present behind or below the object into which the threaded stud is to be driven.
▶ Use the right tool for the work you are carrying out. Do not use the tool for purposes for which it was not
intended. Use it only as directed and when in faultless condition.
▶ Never leave a loaded tool unattended.
▶ Transport and store the tool in a secured toolbox.
▶ Always switch the tool off before cleaning, maintenance, changing the fastener guide, before work breaks
and before storing the tool.
▶ When not in use, the tool should be unloaded and stored in a locked, dry place where it is inaccessible
to children.
▶ Check the tool and the accessories for any damage. Check that moving parts function faultlessly, 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 parts must be properly repaired or replaced by Hilti Service unless otherwise stated in the
operating instructions.
▶ Before beginning work, check the working area (e.g. using a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present. External metal parts of the power tool may become
live, for example, when an electric cable is damaged accidentally.
▶ Do not attempt to drive threaded studs into unsuitable materials.
➥ Unsuitable materials are glass, marble, plastic, bronze, brass, copper, insulating material, hollow
brick, ceramic brick, thin sheet metal (< 4 mm) and cellular concrete. Driving a fastener into these
materials may cause the fastener to break, splinter the material or to be driven right through.
▶ Pull the trigger only when the tool is fully pressed against the working surface at right angles.
▶ When driving fasteners, always hold the fastening tool at right angles to the working surface in order to
prevent the threaded stud being deflected by the surface.
▶ Keep the grips dry, clean and free from oil and grease.
▶ Never drop the tool.
▶ Do not use the tool in places where there is a risk of fire or explosion unless the tool is specially approved
for this type of use.
▶ Secure X-BT fasteners only in holes specially pre-drilled for this purpose.
Workplace
▶ Keep the workplace tidy. Clear the work zone of objects that could cause injury.
➥ Untidiness in the working area can lead to accidents.
▶ Make sure that the working area is well lit and well ventilated.
Mechanical safety rules
▶ Do not tamper with or modify the tool or parts of it, especially the piston.
▶ Use only threaded studs of a type approved for use with the tool.
