Electrical safety
▶ Before use of the pressing tool, all live cables and other equipment carrying electric voltage within the
area in which the user is working are to be switched off. If this is not possible, the corresponding safety
precautions for working in proximity to live cables or equipment must be implemented and observed.
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the product could give you an electric shock or cause an explosion if you
accidentally damage an electric cable or a gas or water pipe.
▶ Do not press live parts, i.e. parts carrying electric voltage. The pressing tool must be considered as being
uninsulated and must therefore be used in combination with personal protective equipment (protective
gloves, protective footwear, protective clothing, etc.) of a type suitable to provide protection for yourself
and other persons in the vicinity.
Power tool use and care
▶ After approx. 50 consecutive pressing operations, switch the pressing tool off and allow it to cool down
for about 15 minutes. Overheating can lead to damage to the pressing tool.
▶ Store the pressing tool in a dry place inaccessible to children and unauthorized persons.
▶ Hilti recommends having the crimping tool overhauled by Hilti Service after 15,000 crimping operations.
▶ Before starting work, check the pressing tool, the pressing jaws (NPR PS) or, as applicable, the pressing
rings (NPR PR) in accordance with the instructions. Inadequately tested pressing tools, jaws or rings can
lead to substandard pressings and are a potential safety risk for the operator.
▶ Make sure that there are no foreign objects (e.g. plaster, grit particles, metal cuttings, etc.) in the pressing
jaws and no parts are damaged. Do not continue to use damaged or distorted pressing jaws!
2.3 Careful handling and use of batteries
▶ Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
▶ Use only batteries that are in perfect working order.
▶ Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶ Do not under any circumstances modify or tamper with batteries!
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶ Never use or charge a battery that has suffered an impact or been damaged in any other way. Check
your batteries regularly for signs of damage.
▶ Never use recycled or repaired batteries.
▶ Never use the battery or a battery-operated power tool as a striking tool.
▶ Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This
can lead to explosions.
▶ Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects.
This can damage the battery and also cause material damage and personal injury.
▶ Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits,
electric shock, burns, fire and explosions.
▶ Use only chargers and power tools approved for the specific battery type. Read and follow the relevant
operating instructions.
▶ Do not use or store the battery in explosive environments.
▶ If the battery is too hot to touch, it may be defective. Put the battery in a place where it is clearly visible
and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Consult Hilti Service or read the
document entitled "Instructions on safety and use for Hilti Li-ion batteries".
Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
