Bosch 4000 Table Saw PROBLEM

[732895]

Hi,

I have a Bosch 4000 Table saw, it is between 2 & 3 years old. Serial # 79114 1060.

Well looked after, little use, never got wet. I was using it yesterday to make some rip cuts on some trim. I had just started a cut when the power tripped out, the motor was not being overloaded. I re-set the switch on the consumer unit, and when I re-started the saw it now only turns backwards and at approximately half speed!!!

I have plugged other tools into same socket without the same result and I have plugged the saw into a different socket with, unfortunately, the same result of backwards and slow!

Do you have any ideas what has happened to my saw?
What is the warranty issue on the motor, which seems to me to be the issue?
How much is a new motor and can I fit it easily?

Any help or advice would be greatly appreciated before I take it to a repair centre.

Kind regards
Simon

Hi Simon, Your speed control unit is bad.The reason its turning backwards is this controls the brake which reverses the motor for a fraction of a second the brake is stuck in the on position.Replace the speed controller and this should fix your problem. Hope that helps.good luck

Hello Simon,

I agree with Tinkerdave with his assessment of your problem. The speed control on that saw is the cause of a few problems with the motor on that saw.
