Festo ATF 55 EB problem with rpm, green/red lamp
« on: October 20, 2019, 08:59 AM »
Hello

Were cutting for a 30 minutes before I noticed that the machine didnt speed up to rpm and that the green lamp that lights when I start the machines turns into red slightly after.

The machine runs but just not runs up to speed and just spins the blade around.

The machines electic house was a little hot before but has been resting for a time now and is now cool again, but still the same problem.

Any ideas?

Sorry, sounds like the motor is burned out. Time to trash the old lady.
