2 Safety
2.1 Safety precautions
In addition to the information relevant to safety provided in the individual sections of these operating
instructions and the information provided in the operating instructions of whichever type of rotating
laser is being used, the following instructions must also be strictly observed at all times.
General safety instructions
Do not render safety devices ineffective and do not remove information and warning notices.
Proper preparation of the working area
▶ Secure the site in which you are taking measurements and take care to avoid directing the beam
towards other persons or towards yourself when setting up the appliance.
▶ When performing alignment work on ladders, avoid postures to which you are unaccustomed.
Make sure you work from a safe stance and stay in balance at all times.
▶ Ensure that the tool is set up on a stable, level surface (not subject to vibration).
▶ Use the tool only within its specified limits.
▶ Take care to ensure that no parts of the body are located under the tripod when the tripod is set
up or in operation.
▶ Do not use the tripod as a hoist or lifting aid.
▶ Keep children away. Keep other persons away from the working area.
▶ When setting up the tripod in enclosed spaces (indoor rooms), check the suitability of the floor on
which it stands, as the tripod could gouge scratches into the floor.
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 tool 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).
General safety measures
▶ Check the condition of the device before use. If the device is found to be damaged, have it repaired at a
Hilti Service Center.
▶ Always keep the PRA 90 threaded rod free from objects of any kind, including parts of the body or
dirt.
▶ Do not put your fingers or other parts of the body into the tubes of the tripod legs or other points
at which injuries may be caused.
▶ Although the appliance is designed for use on job sites under tough conditions, it should be
handled with care, in the same way as other electrical appliances.
▶ Although the device is protected to prevent entry of dampness, it should be wiped dry each time
before being put away in its transport container.
▶ Only use the AC adapter for connecting to the power supply.
▶ Ensure that the appliance and AC adapter do not present an obstacle that could lead to a risk of
tripping or personal injury.
▶ Ensure that the workplace is well lit.
▶ Check extension cords at regular intervals and replace them if found to be damaged. Do not touch
the AC adapter if the extension cord or AC adapter are damaged while working. Disconnect the
supply cord plug from the power outlet. Damaged supply cords or extension cords present a risk of
electric shock.
▶ Avoid body contact with earthed or grounded surfaces such as pipes, radiators, cookers, stoves
and refrigerators. There is an increased risk of electric shock if your body is grounded.
▶ Do not expose the supply cord to heat, oil or sharp edges.
▶ Never operate the AC adapter when it is dirty or wet. Dust (especially dust from conductive
materials) or dampness adhering to the surface of the AC adapter may, under unfavorable
conditions, lead to electric shock. Dirty or dusty tools or appliances should thus be checked by
Hilti Service at regular intervals, especially if used frequently for working on conductive materials.
