General Safety Information

  • Do not open the housing. By opening the housing, serious personal injury may be caused and you can damage the product, which will affect the product's warranty.
  • Do not use parts which have not been supplied or recommended by FARO.
  • Only replacement parts authorized by FARO may be used according to the instructions obtained from FARO. 
  • Do not expose the FARO Laser Scanner and its accessories to extreme temperatures. The ambient temperature must not be lower or higher than given in the specifications. Do not use the FARO Laser Scanner near heat sources such as radiators, heat registers, or other products (including amplifiers) that produce heat.
  • Do not immerse the FARO Laser Scanner and its accessories into water. Liquid in the product enclosure can lead to damage, fire, or electric shocks.
  • Properly dispose of the product and batteries in accordance to the national regulations. For more information, see Disposal on page 152.
  • Do not use the FARO Laser Scanner and its accessories in an explosive atmosphere. Do not operate the instrument in the presence of flammable gases or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard.
  • Do not use the FARO Laser Scanner in vicinity of strong magnetic or electrical fields.
  • Before operating the FARO Laser Scanner and its accessories in hazardous areas, contact the local safety authorities and safety experts.
  • For outdoor use, use the Power Block battery as the power supply and ensure that the device is protected from rain or spray water. The scanner should be used in a non-condensing environment.
  • When the product is transferred from a cold to a significantly warmer environment, water may condense on some elements inside the scanner. To avoid this, we recommend placing the scanner in an airtight plastic bag before bringing it from a cold to a significantly warmer environment. This allows the condensation to form on the bag and not inside the scanner. If you do not have the possibility to pack the scanner airtight, wait until observable condensation water evaporates from the scanner before switching the FARO Laser Scanner on.
  • Properly dispose of the product and batteries in accordance to the national regulations.
  • Do not operate the scanner while the external power supply is plugged in. The power cable might damage the turning scanner.

Electrical Safety

  • Do not open the housing. Dangerous high voltages are present inside the enclosure. Only qualified service personnel should open the housing. Never push objects of any kind into this product through openings as they may touch dangerous voltage points or cause short circuits. This could result in a fire, electric shock, and damage to the product.
  • This product should be operated only from the power source or a battery supplied or recommended by FARO. Ensure that the specifications of the AC converter are met by your line voltage. If you do not know the power line voltage in your area, consult your local power company.
  • To avoid electrical shock, use the power supply unit in dry indoor environments only. 

Power Block Battery Safety Measures

Following safety measures must be followed when working with the Power Block battery:

  • Only use the charger recommended by FARO to charge the battery.
  • Do not charge or discharge damaged batteries.
  • Do not charge the battery in the FARO Laser Scanner when it is stored in the transport case.
  • Do not use wet or dirty batteries in the FARO Laser Scanner or with the charger. • Charge within limits of 0°C (32°F) and 45°C (113°F) temperature. Recommended charging temperatures: 10°C (50°F) to 30°C (86°F).
  • Discharge within limits of -20°C (-4°F) and 60°C (140°F) temperature. Recommended operating temperatures: 5°C (41°F) to 40°C (104°F).
  • Insert or remove batteries from the laser scanner in dry and dust-free environments only.
  • When the FARO Laser Scanner is not in use for a longer period of time, remove the battery.
  • Store the battery only when it is charged (at least 50% charge state).
  • Storage temperatures: -20°C (-4°F) to 45°C (113°F), storage humidity range: 0% to 80%. Store in a well ventilated area.
  • Do not store with metal objects. A short circuit can cause a fire. Do not bring metal objects into contact with the batteries' terminals. The terminals may short circuit and generate heat in this condition.
  • Do not immerse batteries into water or fire (danger of explosion).
  • Dispose of batteries in accordance with environmental regulations. Contact your local waste disposal management authority for guidelines concerning lithium ion batteries.

Power Dock Battery Charger Safety Measures

  • Observe the following safety measures when working with the FARO Power Dock battery charger:
  • Do not charge any batteries other than the FARO Power Block batteries in the FARO Power Dock charger.
  • Regularly check plug, cord, and the charger itself. In case of damage contact the FARO Customer Service.
  • Do not bring metal objects or fluids into contact with the charger terminals. The terminals may short circuit and generate heat in this condition.
  • To avoid electrical shock, use the charger and the power supply unit in dry indoor environments only. • Do not operate the charger in an environment allowing exposure to moisture, combustible fluids or gases. Danger of explosion!
  • The charger should be kept in a dry room, out of the reach of children.

Mechanical Safety

  • Rotating Mirror - The mirror unit rotates with high speed while scanning and for a short period after the scan. While the mirror is rotating keep distance to the product and do not touch the rotating mirror unit with your hands, fingers or any objects at the risk of personal injury and damage to the FARO Laser Scanner.
  • General Use - The FARO Laser Scanner may only be used when set on a flat and stable surface. Injuries may result if the FARO Laser Scanner overturns. Only use equipment recommended by FARO and follow the setup instructions in this manual or in the manual of the manufacturer of the equipment. Do Not Open the Housing By opening the housing serious personal injury can be caused and you can damage the product.
  • Cart Usage - If using a cart, move the setup with special care. Never move the cart by pulling the power cables. Pushing or pulling of the cart with too much force, sudden stops, or an uneven surface can cause an upset of the FARO Laser Scanner.
  • Rotating Scanner - The FARO Laser Scanner will rotate clockwise up to 360 degrees when performing a scan. Ensure that the scanner head of the FARO Laser Scanner can rotate freely and will not hit any objects during the scan.
  • Replacement Parts - Only replacement parts authorized by FARO can be used according to the instructions obtained from FARO. Do not use parts which have not been supplied or recommended by FARO.
