Question about Dewalt D28402K Heavy Duty 4 - 1/2" Small Angle Grinder Kit

1 Answer

My son's Dewalt D28402 angle grinder gets so hot on the metal "gear box" area that you can't leave your had on it. This happens after about 5 minutes of off/on use. Is this normal? Can the lubricant be changed? If so, with what?\r\nthanks

  • 1 Check the grinder before you begin. The newer discs on rotary grinders have patented buttons that allow you to remove the disc without any tools. You may have one like that. In models like this, there's usually a spot to depress and then remove the disc.

  • 2 Turn off the grinder before you attempt to remove and change the disc on your rotary grinder. If it's battery powered, put the grinder in lock position so you can't accidentally turn it on. If it's electric, unplug the grinder from the wall.
  • 3 Look for a nut in the center of the disc. This is a give away that you need to use your special wrench. Sometimes the grinder comes with a tool necessary to loosen and remove the nut. Other times you need to use a wrench.
  • 4 Lock the wheel into place before you begin. You can find a button or switch at the side or back that allows you to do that. When you lock the wheel in place, the disc remains still as you loosen the nut in the center.
  • 5 Remove the nut in the center with either the tool provided with the grinder or a shop tool and lift the disc off your rotary grinder.
  • 6Lift the disc off the rotary grinder. If you have different discs, remember to check for the best fit. Put the nut back on a different way for different discs. Check for a rim and indentation on one side of the nut and a flat side on the other. A visual inspection of the disc for the rotary grinder gives you information about the side to use.

    What do you mean wheel side out? It should look just like the picture, the nut side of the disc threads on first. Depending on what disc you want to put on you may need a spacer that goes on first and then a threaded washer on the outside.

    How do i change wheels


    There usually is a locking pin that stops the wheel from turning. MAKE SURE YOU HAVE THIS UNIT UNPLUGGED!!! Press this button in while slowly rotating the wheel, once it engages the wheel will lock. With your wrench you can now take off the blade. It may have a left handed thread so going clockwise will loosen it.

    My dewalt dw 402 grinder, starts fine, runs for a few minutes and then shuts down. Brushes appear to be fine.


    Pull it apart and clean the armature, you will find something between the brush contacts getting larger and making contact thus shorting it out, so clean the armature with fine point object do not gouge the material out of the area between the copper plates. Also blow out any metal dust you may see.
