Additional safety instructions for pressing tools
Personal safety
▶ Use the product only if it is in perfect working order.
▶ Never tamper with or modify the tool in any way.
▶ Never carry out crimping / pressing work on parts of a gas supply network unless express approval has
been given by the system supplier for use of this tool in conjunction with specially tested and approved
fittings.
▶ If you notice oil escaping, cease working with the tool and consult Hilti Service. Immediately remove the
leaked oil.
▶ Check that the locking pin is pushed in all the way and securely engaged.
▶ Make sure that there are no foreign objects (e.g. plaster, grit particles, metal cuttings, etc.) in the crimping
/ pressing jaws and no parts are damaged. Do not continue to use damaged or distorted crimping /
pressing jaws!
▶ Throughout the crimping / pressing operation, take great care to keep your hands and fingers well clear
of the crimping / pressing head.
▶ Switch the crimping / pressing tool on only after bringing it to the working position.
▶ Always hold the crimping / pressing tool firmly with both hands on the grips provided for the purpose.
▶ Keep the retaining strap and the tether clean and dry.
▶ Before starting work, check the crimping / pressing tool and the NPR PM crimping / pressing
jaws in accordance with the instructions. Inadequately tested tools and jaws can lead to substandard
crimpings / pressings and are a potential safety risk for the operator. Crimping / pressing tools must
undergo inspection by Hilti service at the latest every 15,000 crimping / pressing operations and at least
once a year. Crimping / pressing jaws must undergo servicing by Hilti service at least once a year.
▶ After crimping / pressing, pressure-test the tubing system to ensure that it is free of leaks (resulting from
misuse of the tool, for example).
Electrical safety
▶ Before use of the power tool, all live cables or other items 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 using the crimping / pressing tool, make sure there are no concealed electric cables or gas or
water pipes in the working area. External, metallic or electrically live parts can give you an electric shock
if you inadvertently damage electric cables or gas or water pipes.
▶ Do not crimp live parts. The tool must be considered to be uninsulated and must therefore be used
in conjunction 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 crimping / pressing operations, switch the power tool off and allow it to
cool down for about 15 minutes. Overheating can lead to damage to the power tool.
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.
