DeWalt DW420 Problems and Solutions

some common issues and problems with the DeWalt DW420 and their solutions, as provided by experts:

The saw blade does not spin. This is usually caused by a problem with the switch or the belt. To check the switch, unplug the saw and use a multimeter to test for continuity between the two terminals. If there is no continuity, the switch needs to be replaced. To check the belt, make sure that it is properly installed and that it is not damaged. If the belt is damaged, it needs to be replaced.
The saw blade wobbles. This is usually caused by a loose arbor nut. To tighten the arbor nut, you will need a wrench. First, unplug the saw and remove the blade. Then, use the wrench to tighten the arbor nut until it is snug. Be careful not to overtighten the nut, as this could damage the saw.
The saw makes a loud noise. This could be caused by a number of things, such as a loose belt, a worn-out bearing, or a problem with the motor. To troubleshoot the noise, you will need to listen carefully to the saw and try to identify the source of the noise. If you can't identify the source of the noise, you may need to take the saw to a qualified repair technician.
The saw stops working. This could be caused by a number of things, such as a blown fuse, a tripped breaker, or a problem with the motor. To troubleshoot the problem, you will need to check the fuse box and the breaker box. If the fuse or breaker is tripped, reset it and see if the saw starts working. If the saw still doesn't start working, you may need to take it to a qualified repair technician.

Here are some additional tips from experts for preventing problems with the DeWalt DW420:
