DeWalt D28402K Problems and Solutions

some common issues and solutions for the DeWalt D28402K angle grinder, as explained by an expert:

• The grinder won't turn on. This is usually caused by a faulty switch. To check the switch, you will need a multimeter. Set the multimeter to the continuity setting and touch one probe to the brush terminal and the other probe to the switch terminal. If you get a reading, then the switch is good. If you don't get a reading, then the switch is faulty and needs to be replaced.
• The grinder is smoking. This is usually caused by a bearing that is going bad. To check the bearings, you will need to remove the grinder's side covers. Once the covers are removed, spin the grinder's armature by hand. If you feel any roughness or binding, then the bearings need to be replaced.
• The grinder is not spinning at full speed. This is usually caused by a dirty or clogged air filter. To clean the air filter, you will need to remove it from the grinder. Once the air filter is removed, blow it out with compressed air or vacuum it clean. If the air filter is still dirty after cleaning, then it needs to be replaced.
• The grinder is making a strange noise. This could be caused by a number of things, such as a loose nut, a bent shaft, or a worn bearing. To diagnose the noise, you will need to listen carefully to the grinder while it is running. Once you have identified the source of the noise, you can take the necessary steps to fix it.
