Bosch GEX 125 AC Professional Problems and Solutions

some common issues and problems with the Bosch GEX 125 AC Professional and their solutions:

  • The sander won't start. This is usually caused by a faulty power cord or a problem with the trigger switch. To check the power cord, plug it into another outlet and see if the sander starts. If it does, then the power cord is not the problem. To check the trigger switch, use a multimeter to test for continuity. If there is no continuity, then the trigger switch needs to be replaced.
  • The sander is not sanding evenly. This is usually caused by a dull sanding disc. To check the sanding disc, look for any cracks or chips. If the sanding disc is damaged, then it needs to be replaced. You can also try adjusting the sanding speed to see if that helps.
  • The sander is making a loud noise. This is usually caused by a bearing that is going bad. To check the bearings, listen for any grinding or rattling noises coming from the sander. If you hear any noises, then the bearings need to be replaced.
  • The sander is smoking. This is a serious problem and should not be ignored. Smoking can be caused by a number of things, including a short circuit, overheating, or a fire. If your sander starts smoking, immediately unplug it and turn it off. Do not use the sander again until you have identified and fixed the problem.
