    K lets start with the model number. I am confused with what you mean by "backwards" is the saw running in reverse? Have you done any repair work to the motor in this tool? Let me know and we will see what can be done/

Replace the field coil. I'm going to bet its a Model 4000. I have done about 100 of these saws in the last couple of years and my customers always complain of the same problem, "the saw was running backwards"

Change the armature back bearing while you have it apart, they always seize eventually.

Bosh 4000 table saw runs backward and at low speed


I've worked on some table saws with problems like you describe, a couple needed a new speed control unit (Bosch PN 2610997306) in the motor. If all the wiring to and inside the motor is OK and not shorting out anywhere, that's the next part you should look at.

Just replaced speed control unit and saw still spins at very slow rpm, guessing 20-30. any other possibilties. any way to check if new control unit is no good?


With the saw unplugged, turn the saw blade.
If it turns easily with no hangups I would guess its the field.
When mine went bad the blade went backwards very slowly.
I replaced only the field and not the armature and it's worked fine for over 2 yrs.

Right now I have it apart to change an armature bearing which was completely frozen up.

My 4000 started running backwards very slowly - is it a field winding or maybe the speed controller? And if it is the speed controller, where is it and can I bypass it to test it?


I am not aware of any speed controller on this tool. what I would do is unplug tool and turn it on its backside and look at the switch to see if possibly burnt causing problems.

Bosch 4000 Table Saw running backward


You can find the 4000 manuals and parts diagram at bosch tools online. You will need a new armture Bnew bushes and possibly field. I would also replace the bearings and motor speed control circuit board.
Bosch does not sell the motor assembly.
Turn unit upside down and remove the Plastic body - approx 6 screws.
Thake a digital camera and take LOTS of pictures of dissassembly as you will need them later. Blow unit clean and work neatly keeping all parts in labeled bins for reassembly. Don't attempt this job when your pressed for time.
Before you start check to see if this machine is still under warranty!!
Call customer support listed on website if you run into a problem.
Good Luck !!

Saw is rotating backwards can you help. its a power devil table saw


This happens with Bosch saws once in a while. The field coil in the motor short circuits. This causes the saw to run very slowly or sometimes run backwards. I sounds like yours has this problem. Unfortunatly the only way to repair the motor is to replace the field coil. This is a fairly involved repair and you might benifit from taking to a power tool service center.

Bosch 4000 tablesaw suddenly ran backwards and died


I had a customer bring me a saw with this same problem. All components tested OK on my growler. I went on a limb since the speed control and the armature tested OK. I replaced the feild since to me it seemed to be the only component that could cause the motor to run in reverse. Tool now works properly and have had no more problems with the tool.
