2.1 Safety instructions

2.1.1 Basic information concerning safety

Read all safety instructions and other instructions. Failure to observe the safety instructions and other
instructions may result in electric shock, fire and/or serious injury.
Retain all safety precautions and instructions for future reference. The term "electric tool" used in the
safety instructions refers to your mains-operated (corded) electric tool or battery-operated (cordless) electric
tool.

2.1.2 General safety instructions

▶ Stay alert, watch what you are doing and use common sense when operating an electric tool. Do
not use an electric tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating the electric tool may result in serious personal injury.
▶ Do not render safety devices ineffective and do not remove information and warning notices.
▶ Keep laser tools out of reach of children.
▶ Laser radiation in excess of Class 2 may be emitted if the tool is opened without following the correct
procedures. Have the tool repaired only by Hilti Service.
▶ Laser beams should be projected well above or well below eye height.
▶ Take the influences of the surrounding area into account. Do not use the tool where there is a risk
of fire or explosion.
▶ Statement in accordance with FCC §15.21: Changes or modifications not expressly approved by Hilti
may restrict the user's authorization to operate the equipment.
▶ You must check the accuracy of the tool after it has been dropped or subjected to other mechanical
stresses.
▶ When the tool is brought into a warm environment from very cold conditions, or vice-versa, allow
it to become acclimatized before use.
▶ Make sure that the tool is mounted securely when adapters or accessories are used.
▶ Keep the laser exit aperture clean to avoid measurement errors.
▶ Although the tool is designed for the tough conditions of jobsite use, as with other optical and
electronic instruments (e.g. binoculars, spectacles, cameras) it should be treated with care.
▶ Although the tool is protected to prevent entry of dampness, it should be wiped dry each time
before being put away in its transport container.
▶ Check the tool before using it for important measuring work.
▶ Check the accuracy of the measurements several times during use of the tool.
▶ Ensure that the workplace is well lit.
▶ Do not expose the laser to rain or wet conditions.
▶ Avoid touching the contacts.
▶ Maintain the tool carefully. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the tool's operation. Have damaged parts repaired before
using the tool. Many accidents are caused by poorly maintained tools.

2.1.3 Proper preparation of the working area

▶ Secure the area in which you will be taking measurements. Make sure that the laser beam is not
directed toward other persons or toward yourself while setting up the PR 2-HS A12.
▶ Avoid unfavorable body positions when working from ladders. Make sure you work from a safe
stance and stay in balance at all times.
▶ Readings taken in the vicinity of reflective objects or surfaces, through panes of glass or similar materials
may produce incorrect results.
