      If your Blastrac Floor Machine won't start and the green control light is off, several issues could be the cause. First, ensure that your connected dust collector has sufficient suction power and is turned on. Next, inspect the dust hose and its connections for any blockages or damage. Also, check the measuring point inside the dust hose connection for blockages. Verify that the air hoses and connections are free from blockages or twists. Examine the filter and replace it if it's clogged. Lastly, confirm that the differential pressure switch is correctly set to -10mbar.

      Jessica BeanAug 7, 2025
      Excessive vibration and unusual noises in your Blastrac Floor Machine can stem from a few key issues. Start by checking for worn or broken grinding tools and replace them. Next, inspect the bearing on the axle drive shaft and replace it if defective. Finally, examine the coupling for any debris deposits and clean it thoroughly.

      Sandra DoyleAug 13, 2025
      If your Blastrac Floor Machine motor triggers while running, it could be due to a motor protection switch triggered by an overload. Try reducing the additional load. If that doesn't solve the problem, the motor itself might have a defect, so you should check the motor.

    Why is my Blastrac Floor Machine having reduced or no grinding performance?
    • L
      Lisa OwenAug 20, 2025
      Reduced or no grinding performance in your Blastrac Floor Machine can occur if the grinding tools have reached their maximum permissible wear. If this is the case, replace the worn parts. Another reason may be that the grinding tool is not appropriate for the surface application. Replace the grinding tools with appropriate ones for the surface you are treating.

    How to troubleshoot if Blastrac Floor Machine motor does not switch on?
    • K
      Kathleen JohnsonAug 27, 2025
      If the motor of your Blastrac Floor Machine does not switch on, first check the mains power supply and switch it on again, as a missed phase could be the cause. If the issue persists, a defective component might be the problem. In this case, you should find the fault and replace the defective component.
