Working safely with laser tools

  • Laser Class 3/Class III 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.
  • Store laser tools, when not in use, in places to which unauthorized persons have no access.

Electromagnetic compatibility

Although the device complies with the strict requirements of the applicable directives, Hilti cannot entirely rule out the possibility of interference to the device 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). The tool complies with the requirements of Class A; The possibility of interference occurring in a domestic environment cannot be excluded.
Only for Korea: This laser range meter is suitable for commercial and industrial use and for the electromagnetic radiation encountered in this field (Class A). Users must pay attention to this point and make sure that this laser range meter is not used in occupied living areas.

The tool is designed to be used for determining, transferring or checking alignment in the horizontal and inclined planes. The tool is a pipe laser featuring a visible laser beam.
If the tool is set up outside its self-leveling range, the laser beam and the LED on the control panel blink. The direction in which the tool requires to be tilted is also shown in the display.
Three different electric power supply sources may be used. These are the PPA 82 battery (supplied as standard) or the PPA 83 battery holder or PPA 84 external 12 V connecting cable (available as accessories).
The performance of the PPA 82 battery drops at low temperatures. Store the battery at room temperature. Never store it where it is exposed to the heat of the sun, on a heating unit or behind glass, e.g. at a window.
Charging is stopped automatically to protect the battery when the temperature is outside the specified charging temperature range.
The tool is designed to withstand submersion to a depth of up to 5 m for a time of up to 24 hours.

Checking accuracy

  1. Set the laser to an inclination of 0.000%.
  2. Set up a leveling staff at a distance of 1 m (3.3") from the laser tool and another leveling staff at a distance of 60 m (196.85").
  3. Make a note of the heights at which the laser beam strikes the leveling staffs.
  4. Set up an optical level in the middle between the two leveling staffs and read the heights from both staffs.
  5. Calculate the difference between the height readings from the optical level and the laser beam at staffs 1 and 2.
    • If both values are identical, the laser tool is correctly adjusted.
    If the differences X1 and X2 are not within tolerance, please contact your local Hilti Center or representative.
