  • The saw won't start. Make sure that the saw is plugged in properly and that the circuit breaker is not tripped. If the saw still won't start, check the brushes. The brushes are located in the motor housing and they can wear out over time. If the brushes are worn out, they will need to be replaced.
  • The saw is making a loud noise. This could be a sign of a problem with the bearings. The bearings are located in the motor housing and they help to reduce friction. If the bearings are worn out, they can make a loud noise and cause the saw to vibrate. If you hear a loud noise coming from your saw, it's best to take it to a qualified technician to have the bearings replaced.
  • The saw is not cutting straight. This could be a sign of a problem with the blade. The blade is located in the saw's head and it's responsible for cutting the wood. If the blade is dull or damaged, it can cause the saw to cut unevenly. To check the blade, remove it from the saw and inspect it for any signs of damage. If the blade is dull, you can sharpen it using a sharpening stone or a power sharpener. If the blade is damaged, it will need to be replaced.
  • The saw is not making a cut. This could be a sign of a problem with the saw's trigger. The trigger is located on the saw's handle and it's responsible for activating the motor.
