▶ Measurements taken from surfaces with low reflectivity in highly reflective surroundings
may be inaccurate.
▶ Measurements taken through panes of glass or other objects may be inaccurate.
▶ The measurement may be incorrect if the conditions under which the measurement is
taken change rapidly, e.g. due to people walking through the path of the laser beam.
▶ Do not point the product toward the sun or other powerful light sources.
▶ The product and its ancillary equipment may present hazards when used incorrectly
by untrained personnel or when used not as directed.
▶ To avoid the risk of injury, use only genuine Hilti accessories and additional equipment.
▶ Observe the information printed in the operating instructions concerning operation,
care and maintenance.
▶ Never use the product without having received the appropriate instruction on its use
or without having read this documentation.
▶ Due to the principle employed, the results of measurements may be negatively affected
by the surrounding conditions. This includes, e.g. close proximity to equipment that
generates powerful magnetic or electromagnetic fields, taking measurements from
unsuitable surfaces and use of unsuitable reflectors.
▶ Measurements to plastic foam surfaces, e.g. polystyrene foam, to snow or to highly
reflective surfaces, etc. may result in incorrect readings.
2.2 Proper preparation of the working area
▶ Avoid unfavorable body positions when working from ladders. Make sure you have a
safe stance and that you stay in balance at all times.
▶ Secure the site at which you are taking measurements and take care to avoid directing
the laser beam toward other persons or toward yourself.
▶ Use the product only within its specified limits. Do not direct the laser beam toward
mirrors, stainless steel, polished stone or similar surfaces.
▶ Keep the laser exit window clean in order to avoid measurement errors.
▶ Observe the accident prevention regulations applicable in your country.
2.3 Electromagnetic compatibility
Although the laser range meter complies with the strict requirements of the applicable
directives, Hilti cannot entirely rule out the possibility of interference to the laser
range meter caused by powerful electromagnetic radiation, possibly leading to incorrect
operation. Accuracy must be checked 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). The laser
range meter complies with the requirements of class A: The possibility of interference
occurring in a domestic environment cannot be excluded.
2.4 Working safely with laser tools
▶ Laser Class 2 tools may be operated only by appropriately trained persons.
▶ Laser beams should not be projected at eye height.
▶ Precautions must be taken to ensure that the laser beam does not unintentionally
strike highly reflective surfaces.
▶ Precautions must be taken to ensure that persons do not stare directly into the beam.
▶ The laser beam must not be allowed to project beyond the controlled area.
▶ Switch the laser tool off when it is not in use.
▶ Activate the locking function in the tool settings in order to prevent unauthorized
persons, especially children, from activating the laser beam.
