Dremel 7700 Problems and Solutions

some common problems with the Dremel 7700 and their solutions:

Problem: Dremel not spinning properly.

Solution:

Unplug the tool.
Check to see if the shaft spins freely. If not, you may have a bearing problem.
You can sometimes free up a bad bearing with light oil, but noisy bearings mean mechanical damage and it should be replaced as soon as possible.
If the bearings are bad, then the whole armature will need to be replaced.

Problem: Dremel bit keeps falling out.

Solution:

The most likely reason your drill bit keeps coming loose is the chuck on your drill is worn out and not locking properly.
To fix this, you can try cleaning the chuck with a wire brush and then tightening it again. If that doesn't work, you may need to replace the chuck.
Another possibility is that the bit is not compatible with the chuck. Make sure that the bit is the correct size and type for the chuck.

Problem: Dremel battery not working.

Solution:

The first thing you should do is check the battery contacts for corrosion. If they are corroded, you can clean them with a pencil eraser or a small wire brush.
If the contacts are clean and the battery still doesn't work, then the battery may be dead. You can try charging the battery or replacing it.

Problem: Dremel overheating.

Solution:

If your Dremel is overheating, it is likely because you are using it on a high setting for too long.
To prevent overheating, try using a lower setting or taking breaks to let the tool cool down.
You should also make sure that the vents on the tool are not blocked.

I hope this helps!
