No Power coming from tool

Hi Kevin,

It's hard to say without seeing the tool but from what I can tell from your post is that you need a new battery or new charger.

When you put the battery on the charger it should blink. When the battery is fully charged the lights should be solid green. If the battery has had enough time to charge it should be good to go. From my research this seems like a common problem with that model.

Not sure how long you've had this tool but it does come with a 2 year warranty.

3 "flashing" lights means the battery is to hot for use.

If you have a defective unit you can contact dremel and they may send you a replacement.

Hi Kevin,

From my research I can say that you probably have a faulty battery or charger.

The green lights blink when the battery needs charged. If the batter was given enough time to charge the lights will be solid green.

I know your tool should come with a 2 year warranty. I would check into that if it's within the time frame.

Hi Kevin,

This is not the battery.

I have the same problem with a 8200. Bought a 8220 (latest model) and its new battery causes the same 3 flashing lights in the 8200 but the old 8200 battery works fine in the 8220.

Therefore the tool itself is bad.

My ginour mini rotary tool stopped working and 3 red lights stay on can I fix it myself?

I have the sam problem but if you slam the battery in quickly it will go on and work you can control speed but the on off switch doesn't work unfortunately. You have to remove battery again when you're done using it to turn off. I lower speed to lowest setting then remove battery to turn off. Hope this helps get some more use

I have had the same issue on my Dremel 8220, took it apart and found the on/off micro switch is knackered, bought a new one from RS components and fitted it, all tested. Switch was £3.68 and postage was £6.95 (a bit steep) but all working again.
