Hilti PM 20-CG Manual De Instrucciones Original página 30

▶ Check the accuracy of the product before use and several times during use.
▶ Readings taken in the vicinity of reflective objects or surfaces, through panes of glass or similar materials
can falsify the result of measurement.
▶ Mount the product on a suitable holder or bracket or on a tripod, or set it on a smooth, level surface.
▶ Do not work with surveyor's staffs in the vicinity of high-voltage electricity cables.
▶ Make sure that no other laser measuring tool that can influence your measurements is in use in the
vicinity.
▶ Do not permit the laser beam to project beyond the controlled area.
2.3 Additional safety instructions
▶ Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
▶ To achieve maximum accuracy, project the line onto a vertical, flat surface. To do so, set up the product
at 90° to the surface.
2.4 Electromagnetic compatibility
Although the product complies with the strict requirements of the applicable directives, Hilti cannot entirely
rule out the possibility of interference to the product caused by powerful electromagnetic radiation, possibly
leading to incorrect operation. Check the accuracy of the device by taking measurements by other means
when working under such conditions, or if you are unsure. Likewise, Hilti cannot rule out the possibility of
interference with other devices (e.g. aircraft navigation equipment).
2.5 Laser classification for Class 2 laser products
The product corresponds to Laser Class 2 in accordance with IEC ⁄ EN 60825­1:2014 and in accordance with
CFR 21 § 1040 (FDA). This product may be used without need for further protective measures. Nevertheless,
as with the sun, do not look directly into the light source. If you do inadvertently look into the laser beam,
immediately close your eyes and move your head clear of the laser beam. Do not aim the laser beam at
persons.
2.6 Careful handling and use of batteries
PM 20­CG A12
▶ 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 take apart, squash or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ 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.
