Flex Overheating?

[duffthebluff]

Hello AG!

I bought my Flex 3401 just recently, however I was doing my first job with Flex and just around 10 mins of using the polisher it wouldnt start. I noticed that the metal housing that holds the backing plate is hot. I waited for around 20 mins or so for the metal to cooldown then it started again. After I buffed one portion, my flex didnt start again.Is my Flex overheating?

The Flex does get quite warm during use. Most will tell you to check the felt ring to make sure it is oiled.

I have a Flex 3401 too. I have had no heating issues. However, that being said, the main culprit from the heating issue for the Flex or any DA is the gauge of the electrical cord. I know I use a heavier duty extension cord and it even has a protection strip in case of overload.

Check into that after you check the oiling of the felt tip ring on the Flex. I just put WD-40 around the felt ring and that seems to reduce the heat.

But IMO the most important thing is to make sure you have the proper gauge electrical cord connected to the Flex.

Check that out

On the flex you need to,take the backing plate off and use some 3 in 1 oil on the white ring around the housing. This will,help with overheating. Also remember with the flex you do not need a lot of downward pressure. I had the same issue with the flex and the housing was getting hot to the touch and was getting burnt. I was at a detailing meet which had the rep there from flex. He explained that oiling the white ring and using less pressure and going slower will help.

This past weekend I did a detail and used my flex and followed his recommendation and no heat build up on the flex housing.
Just some information.

In regards to the extension cord I use a 50' 12 gauge extension cord and that did not have any bearing on the heat build up.

what gauge cord are you using?

what gauge cord are you using?

Only 10 minutes of use and it shut off is more likely the extension cord than felt ring.

Oh, I dont use any extension cords, is that required? I do use a step down transformer thats rated 3000W because I have the 120v model and I live in a 220v country.

I am not an expert, however, the power converter and the fact your country is a 220v country might be the issue. I do know that AGO carries a specific 220v Flex 3401.

But IMO, I think this is the case....

buy a 50ft 12gauge extension cord...

Thanks for the replies, my option really doesnt include in getting a new flex 3401 for 220V, however I got myself a different transformer thats rated for 12 amperes, I'll be trying that one out if it resolves my issue.
