Bosch GSB 120-LI Professional Problems and Solutions

some common issues and problems with the Bosch GSB 120-LI Professional drill and their solutions:

  • The drill does not turn on. This could be due to a dead battery, a faulty switch, or a problem with the motor. To troubleshoot, first check the battery to make sure it is charged. If the battery is charged, try cleaning the switch contacts with a pencil eraser. If that does not work, the motor may need to be replaced.
  • The drill does not drill straight. This could be due to a bent chuck, a worn collet, or a problem with the gearbox. To troubleshoot, first check the chuck to make sure it is not bent. If the chuck is not bent, try tightening the collet. If that does not work, the gearbox may need to be replaced.
  • The drill overheats. This could be due to prolonged use, a high-resistance load, or a problem with the cooling system. To troubleshoot, first stop using the drill and allow it to cool down. If the drill continues to overheat, try using a lower torque setting or a shorter drill bit. If that does not work, the cooling system may need to be repaired or replaced.
