Hi, a friend gave me this pendular saw and it has a problem in the control board.
The motor is DC.
I used an hp printer transformer at 32V directly at the motor and it ran fine but slow(need more voltage?)
It was too slow to cut wood so i ordered some replacement parts hoping to make it work.
The problem was when you turn it on it runs a bit slow and 5 sec later it goes full throttle but more than it should by factory(400 to 1600RPM).
Now i swapped the components in the pictures and it doesn't run always when pressing the on button and when it runs it goes full throttle again and stops after 2 sec.
Anyone have an idea of what is happening? a friend told me those large ceramic? capacitors break a lot. or it could be the diodes?
thanks for any help.
