20 Most Recent Bosch Electric Table Saws Questions & Answers

If you already replaced the brushes you could have a couple problems, the least is the armature commutator needs cleaned and the more expensive is that it needs replaced. This is a problem unless you want to tackle taking the motor partially apart. Let me know what route you want to take either a repair center or looking at the commutator.

Hi, try and change the Carbon Brushes , these are located either side of the motor, you will see a black plastic nut or screw, remove this and you will see a wire inside a spring this will push it's self out and then you can gently pull the Carbon brush out this is about 1/4--1/2 " long ...! if not then replace with new. PS. REMEMBER TO DISCONECT FROM MAINS SUPPLY FIRST....T.C.

My guess is that the motor is bad. Have you changed the brushes? Or if it is a brushless motor that you may need a new motor.

First of all, love the saw. As good as portables can be, the 4000 is really great.

Now, just remedied the blade height adjustment problem, here is how:

Unplug saw.

Removed blade....not easy when you cannot raise the blade, flip the saw upside down and remove the plastic shield, turn saw upright and remove blade.

Used my compressor with blower attachment and blasted all of the dust out of the gears and screw rods with saw upright and upside down, bevel saw to 45 degrees to gain more access..

Sprayed quite liberally with silicone spray lube and gently worked blade height adjustment, adding more lube, cranking wheel, more lube....blade adjustment now works like the day I bought the saw.

DO NOT USE WD40 or the like. This will just attract more dirt in a very short amount of time.

We'll see how the silicone spray holds up.

Good luck,

I found that the remaining problem was a intermittent at the switch, which disassembly and cleaning resolved.
Tilting the motor / blade assembly down allows access from below, to the 3 screws fastening the controller circuit board cover on the brush end of the motor. From there, one can easily test exposed wires for power supply, see that brushes are contacting and clean accumulated sawdust.

i wouldn,t remove unless you think needs new bearings or cannot get to the brushes, turn upside down if has base cover remove and blow out best you can be sure no water in air line.

problem was solved by our handy man he replaced a washer and used candle wax to lubricate the part and it seems to have done the trick. I am still however looking for a manual for the Bosch TS2000 table saw as my husband has miss placed it. I guess I would address the Bosch company for that.
Thank you

Make sure the lockring on the adjustment handle is pulled out. If so, than you've got to clean the adjuster rod and lubricate it.

the starter is dirty. probably has sawdust in it. if you have a compressor you may be able to use it to solve your problem, otherwise look for a service center.

no. do you have a volt ohms meter to check continuity, if so unplug tool and start with the cord to the brush holders, if you get nothing backtrack to the switch. Let me know what the brand and model number is and I will try and help firther. Why did you replace the brushes? were they burnt or the spring collapsed? If so the commutator might need cleaned, but that comes later Let me know

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.

Is it spinning the blade at all? If it is then it is unlikely to be an electrical fault. Have you considered a motor bearing fault? If the motor bearings are worn, it could turn freely by hand, but when powered up it would stutter and stall. The motor is basically a big electro-magnet so if the armature has enough lateral movement, when it is magnetized it could rub against the stator.
If the machine is buzzing, but not spinning the blade it is more than likely going to be caused by a faulty capacitor as this is the component that gives the motor the initial 'kick' in the right direction to get it spinning.
