Hilti NURON AG 5D-22 Mode D'emploi page 36

▶ Secure the workpiece. Use clamps or a bench vise to hold the workpiece in position. The workpiece is
thus held more securely than by hand and both hands remain free to operate the product.
▶ Do not use cut-off wheels for grinding.
▶ Tighten the accessory tool and flange securely. If the accessory tool and flange are not tightened
securely, the accessory tool may work loose from the arbor due to the braking effect of the motor after
switching off.
Electrical safety
▶ 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.
▶ Dirty or dusty products that have been used frequently for work on conductive materials should be
checked at regular intervals by Hilti Service. Dust (especially dust from conductive materials) or
dampness adhering to the surface of the power tool may, under unfavorable conditions, lead to electric
shock.
Workplace
▶ Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Pieces of debris could drop out and / or fall down and injure other persons.
▶ Slits cut in load-bearing walls of buildings or other structures may influence the statics of the structure,
especially when steel reinforcing bars or load-bearing components are cut through.
responsible structural engineer, architect or person in charge of the building project before beginning the
work.
Additional notes on the use of the guards
To avoid the risks below always use the correct guard, see the section headed: "Suitability of wheels for the
equipment used".
▶ If the Standard guard with front cover is used for surface grinding, the guard can touch the workpiece
and thus lead to loss of control.
▶ If a wire brush of a thickness exceeding the maximum permissible thickness is used, the wires can snag
on the guard and break.
▶ If the standard guard is used for cutting off metal with an abrasive cut-off wheel, there is an increased
risk of exposure to sparks and particles and to wheel fragments if the wheel breaks.
▶ If the standard guard is used with or without front cover for cutting or for grinding concrete or masonry,
there is a higher dust load and an increased risk of losing control of the product, which can lead to
kickbacks.
2.4 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.
