Why my Fukuda Laser Level will not power on?

  Kayla PhelpsAug 6, 2025
  If your Fukuda Laser Level won't power on, start by checking the batteries. Dead standard batteries or flat rechargeable batteries are common culprits, as are polarity errors from incorrect battery installation. Always double-check the polarity. Try a fresh set of batteries, avoiding mixing different types or old and new batteries. Also, using a non-original charger can seriously damage the batteries, internal charge circuit, or the laser itself. It's recommended to contact the manufacturer to purchase the correct OEM charger. In addition, ensure that laser beam reflections cannot bounce back to the detector.

  Rachel CooperAug 12, 2025
  If your Fukuda Laser Level detector isn't detecting the laser beam, several factors could be at play. First, check the detector's battery; a low battery may need replacing. Ensure that the FRE-205 is spinning and producing a visible red beam. Verify a clear line of sight without obstructions and confirm that both the laser level and detector are within their specified operating range. Lastly, make sure the protective lighthouse glass is clean and free of dust and dirt.

  Ronnie BellAug 28, 2025
  If your Fukuda FRE-205 Laser Level won't self-level, first, reposition it to ensure it's within ±5 degrees of level. If that doesn't work, try the Factory Reset procedure on page 23. If problems persist, please contact the Service Department: 08000 869 769 who will be able to how to send it for repair.
