DeWalt DWE4120 Problems and Solutions

some common issues and problems with the DeWalt DWE4120 and their solutions:

Issue: The saw doesn't start. Solution: Check the power cord to make sure it's plugged in properly. If it is, check the circuit breaker to make sure it's not tripped. If the saw still doesn't start, check the switch to make sure it's turned on.

Issue: The saw starts but won't cut. Solution: Check the blade to make sure it's sharp and properly aligned. If the blade is sharp and aligned, check the belt to make sure it's not damaged or worn out. If the belt is damaged or worn out, replace it.

Issue: The saw makes a strange noise. Solution: Listen carefully to the noise to try to identify where it's coming from. If the noise is coming from the motor, it could be a sign of a problem with the bearings. If the noise is coming from the blade, it could be a sign of a problem with the alignment. If you can't identify the source of the noise, take the saw to a qualified technician for diagnosis.

Issue: The saw won't stop. Solution: This is a serious safety hazard, so it's important to fix it immediately. First, try to turn off the saw by pressing the switch. If that doesn't work, unplug the saw from the power outlet. If the saw still won't stop, you'll need to take it to a qualified technician for repair.

Issue: The saw blade gets hot. Solution: This is normal for a saw blade, especially when it's being used heavily. However, if the blade gets too hot, it could warp or crack. To prevent this, make sure to take breaks often to let the blade cool down. You should also avoid using the saw on materials that are too hard or abrasive.

Issue: The saw blade wobbles. Solution: This is a sign of a problem with the blade alignment. To fix it, you'll need to adjust the blade alignment screws. There are usually two screws, one on each side of the blade. Turn the screws clockwise to tighten the alignment, and counterclockwise to loosen it. Once the blade is aligned properly, the wobble should go away.
