Makita 9557HN Problems and Solutions

some common problems with the Makita 9557HN angle grinder and their solutions:

• The grinder is not turning on.
  • Check the power cord. Make sure that the power cord is plugged in all the way and that the outlet is working. You can also try plugging the grinder into a different outlet to see if that fixes the problem.
  • Check the switch. The switch on the grinder may be faulty. To test the switch, unplug the grinder and use a multimeter to measure the voltage at the switch. If there is no voltage, then the switch is bad and needs to be replaced.
  • Check the thermal fuse. The thermal fuse is a safety device that is designed to protect the grinder from overheating. If the thermal fuse is blown, the grinder will not turn on. To test the thermal fuse, unplug the grinder and use a multimeter to measure the resistance across the fuse. If the resistance is zero, then the fuse is blown and needs to be replaced.
• The grinder is not spinning at full speed.
  • Check the brushes. The brushes are the components that transfer electricity to the motor. If the brushes are worn out, the grinder will not spin at full speed. To test the brushes, unplug the grinder and remove the brush housing. The brushes should be about 1/8" long. If they are shorter than that, then they need to be replaced.
  • Check the motor. The motor may be faulty. To test the motor, unplug the grinder and connect a multimeter to the motor terminals. The multimeter should read continuity. If there is no continuity, then the motor is bad and needs to be replaced.
• The grinder is smoking.
  • Check the brushes. If the brushes are worn out, they can cause the grinder to smoke. To test the brushes, follow the instructions above.
  • Check the motor. If the motor is faulty, it can also cause the grinder to smoke. To test the motor, follow the instructions above.

If you have tried all of these solutions and the grinder is still not working, then you may need to take it to a qualified technician for further diagnosis.

Here are some additional tips for troubleshooting your Makita 9557HN angle grinder:

• Always wear safety glasses when using an angle grinder.
