DeWalt DWE6421 Problems and Solutions
some common issues and solutions for the DeWalt DWE6421 random orbital sander:
Issue: The disk pad will not hold sandpaper in place.
Solution:
- Make sure that the sandpaper pad is a hook and loop (also known as velcro) pad. The disk pad on the DWE6421 is a hook and loop style pad, and if the sandpaper pad is not a hook and loop pad then it will not stick to the pad.
- If the sandpaper pad is a hook and loop pad, check to see if any debris is on the disk pad. Debris can build up on the disk pad and not allow the sandpaper pad to stick. Try blowing the disk pad out with compressed air or some other cleaning method. While cleaning the disk pad, be sure to wear proper eye protection.
- If the disk pad looks worn or old, it may be time to replace it. A new disk pad will have a better grip on the sandpaper and will help to prevent it from coming off.
Issue: The sander stops working.
Solution:
- Check the power cord to make sure that it is plugged in properly.
- Check the switch to make sure that it is turned on.
- If the sander still stops working, it may be a problem with the motor. In this case, you will need to contact a DeWalt service center for assistance.
Issue: The sander is not collecting dust properly.
Solution:
- Make sure that the dust shroud is properly attached to the sander.
- Check the dust bag to make sure that it is not full. If the bag is full, empty it and replace it with a new one.
- If the dust shroud and bag are properly attached and the sander is still not collecting dust properly, it may be a problem with the fan. In this case, you will need to contact a DeWalt service center for assistance.
Issue: The sander is making a strange noise.
Solution:
- If the noise is a high-pitched whine, it may be a problem with the bearings. In this case, you will need to contact a DeWalt service center for assistance.
- If the noise is a loud clunking sound, it may be a problem with the motor. In this case, you will also need to contact a DeWalt service center for assistance.
