Hilti NURON NRC 6-22 Mode D'emploi page 10

▶ To restart a power tool that is stuck in the workpiece, center the saw blade in the kerf and make sure that
no teeth are snagged in the workpiece. If the saw blade is jammed it can flick out of the kerf or cause
kickback when the power tool is restarted.
▶ Support large rebar to reduce the risk of kickback from a jammed saw blade. Large rebar can bend
under its own weight.
▶ Do not use a dulled or damaged saw blade. A saw blade with dulled or misaligned teeth causes increased
friction, binding of the saw blade and kickback due to a narrow kerf.
Power tool use and care
▶ Never use the product without the blade cover.
▶ Tighten the insert tool and clamping flange securely. If the insert tool and clamping flange are not
tightened securely, the insert tool can work loose from the arbor due to the braking effect of the motor
as it slows down after being switched off.
▶ Match the forward pressure of the product to the saw blade and the workpiece. In this way you prevent
the saw blade from stalling and possibly causing kickback.
▶ Start cutting only after the product has reached maximum speed. Touching the saw blade to the
workpiece before starting the motor overloads and damages the saw blade, possibly resulting in serious
injury.
▶ Do not cut material that in size exceeds the cutting capacity of the product.
▶ Make sure the saw blade is not deformed, chipped, cracked or worn out. Do not use a saw blade that
exhibits damage or wear. Cutting under such conditions can cause further damage to the blade, chip
collection bag with the adapter, and even result in serious injury.
▶ Use only saw blades approved for the product that correspond to the specifications in the technical data.
Using the saw blade for other applications can cause excessive wear, detachment of the blade, low
cutting performance and abnormal generation of heat, resulting in damage to the saw blade and serious
injury.
▶ Do not use the product to cut material that is not specified in Intended Use → page 7.
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 an explosion could result 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
▶ 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 starting work.
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.
