Hilti BX 3-BT Original Operating Instructions page 9

▶ 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.
Thermal safety rules
▶ Do not exceed the recommended maximum fastener driving rate (see the section headed "Technical
data").
▶ If the tool has overheated, allow it to cool down.
▶ Do not dismantle the tool while it is hot. Allow the tool to cool down.
2.4 Battery use and care
▶ Observe the special regulations and instructions applicable to the transport, storage and use of Li-ion
batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. In this case, place the product in a non-flammable
location, well away from flammable materials, where it can be kept under observation and allowed to
cool down. In this case, always contact your Hilti Service.
