• Use of setting-up / adjusting devices and equipment or operating procedures other than those specified in these instructions may lead to exposure to hazardous radiation.
  
• 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.
  
• Measurements taken to 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 PLT 300 or accessories toward the sun or other powerful light sources.
  
• Check the PLT 300 before taking important measurements or after it has been dropped or subjected to mechanical effects such as impact or vibration.
  
• When switching distance measuring mode from prism measurement to reflectorless measurement, make sure that no one can look into the lens of the PLT 300.
  
• The PLT 300 may not be used in the proximity of medical instruments.
  
• Use of the PLT 300 in the proximity of expectant mothers or persons with a cardiac pacemaker is not permissible.
  
• Operation of the PLT 300 in the proximity of military installations, airports or radio astronomy facilities is not permissible unless prior permission has been obtained.
  
• Keep the PLT 300 clean and dry at all times.
  

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 PLT 300.
  
• Check that the tripod stands securely and that the PLT 300 is firmly attached to the tripod by the mounting screw.
  
• Use the PLT 300 only within the defined application limits, i.e. do not take measurements from mirrors, stainless steel surfaces or polished stone, etc.
  
• Observe the accident prevention regulations applicable in your country.
  

Electromagnetic compatibility

• The tool may cause interference to other devices (e.g. aircraft navigation equipment).
  
• The tool may be negatively affected by powerful electromagnetic radiation, possibly leading to incorrect operation.
  

Working safely with laser tools

• Do not stare into the beam and do not direct the beam toward other persons. In the event of direct eye contact with the laser beam, close your eyes and move your head out of the path of the beam.
  
• Laser Class 2/Class II 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.
  
• When not in use, laser tools should be stored in a place to which unauthorized persons have no access.
  
• Have the PLT 300 and PLC 300 repaired only by Hilti Service. If the PLT 300 is opened improperly, laser radiation in excess of Class 2 may be emitted.
  

Careful use of battery-powered tools

• Do not expose batteries to high temperatures, the direct heat of the sun, and keep them away from fire. There is a risk of explosion.
  
• Do not disassemble, squash or incinerate batteries and do not subject them to temperatures over 80°C. This presents a risk of fire, explosion or injury through contact with caustic substances.
  
• Do not subject the battery to hard mechanical impacts and do not throw the battery.
  
• Batteries must be kept out of reach of children.
  
• Avoid ingress of moisture. Ingress of moisture may cause a short circuit, resulting in burning injuries or fire.
  
• Under abusive conditions, liquid may be ejected from the battery. Avoid contact with the liquid. If contact accidentally occurs, flush with water. If the liquid contacts the eyes, also seek medical attention. Liquid leaking from the battery may cause irritation or burns.
  
• Use only batteries of the type approved for use with the applicable tool. Use of other batteries or use of the batteries for purposes for which they are not intended presents a risk of fire and explosion.
  
• Store the battery in a cool and dry place. Never store the battery where it is exposed to direct sunlight or sources of heat, e.g. on heaters / radiators or behind glass.
  
• When not in use, keep the battery and the charger away from paper clips, coins, keys, nails, screws or other small metal objects that could cause a short circuit at the battery terminals or the charging contacts. Short-circuiting the contacts on a battery or charger may cause burning injuries or start a fire.
  
• Do not charge or continue to use damaged batteries (e.g. batteries with cracks, broken parts, bent or pushed-in and/or pulled-out contacts).
  
• Recharge only with the charger specified by the manufacturer. A charger that is suitable for a certain type of battery may present a risk of fire when used with other types of battery.
  
• Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
  
• The battery must be insulated or removed from the tool before the tool is shipped or sent by mail. Leaking batteries may damage the PLT 300.
  

General safety rules

• Before beginning measuring work, check that the accuracy of the tools used is adequate for the requirements of the task.
  
• Do not operate the PLT 300 in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Tools and appliances create sparks which may ignite the dust or fumes.
  
• Wear personal protective equipment, always including protective glasses and protective gloves.
  
• Check the PLT 300 and PLC 300 before use for possible damage. Have any damage repaired by Hilti Service.
  
• Stay alert, watch what you are doing and use common sense when working with the PLT 300. Do not use the PLT 300 while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the tool may result in serious personal injury.
  
• Operating and storage temperatures must be observed.
  
• When the PLT 300 or PLC 300 is brought into a warm environment from very cold conditions, or vice-versa, allow it to become acclimatized before use.
  
• Check the accuracy of the PLT 300 after it has been dropped or subjected to other mechanical stresses.
  
• When a tripod or wall mount is used, check that the PLT 300 is correctly and permanently mounted and that the tripod is standing securely on solid ground.
  
• Keep the laser exit window clean in order to avoid measurement errors.
  
• Maintain the PLT 300 carefully. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect operation of the PLT 300. If parts are damaged, have the parts replaced before use of the PLT 300. Poor maintenance is the cause of many accidents.
  
• Although the PLT 300 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 PLT 300 is protected to prevent entry of dampness, it should be wiped dry each time before being put away in its transport container.
  
• As a precaution, check the previous settings or any adjustments you may have made.
  
• Fasten the battery compartment cover carefully so that the battery doesn’t fall out. If battery contact is lost the PLT 300 will switch itself off, possibly leading to loss of data.
