Bosch TS2000 and the blade won't move to lower or rise

Hi,

It sounds like you've called all 3rd party locations. Please call Bosch directly and request the part. And if they don't have it in the U.S. then you can request the phone number for their international locations. The U.S. phone number is 1-800-944-2904. Otherwise, I would search on ebay and alibaba to find the part that you've mentioned.

Thank you.

Question moved from Bosch Computer, to Bosch 4000 table saw.

Unplug the unit and turn the blade by hand. Check the blade is tight and running true. See if the blade is touching anything. If you can't see anything wrong there, it make be the carbon brushes in the motor.

typically this is a thrust washer issue. need to look at the play between raise and lower..also ensure trunion is cleaned and lubed.

The only solution is to remove the trunnions and threaded rod, thoroughly clean them and lubricate with a silicone based product. Clean these areas at the end of each use to extend the period between tear-downs (yes, you'll probably need to do it periodically). Also, once disassembled, clean and lubricate the guides on the motor mount.
I removed the motor altogether to make this task easier. I recommend cutting the power lead to it and installing a quick connect to avoid having to go through the trouble of disassembling the power switch. Good luck.

there are several rods that support the deck if one is missing it can allow the deck to move in the wrong dirrection

I can't find a Bosch model GCM800 saw in their library but regardless; all arbor nuts, bolts, etc. that hold on blades will loosen if you turn them in the same direction the blade spins when cutting. This makes them self tightening so the blade won't come off while in use.

it lowers easy because of the weight of the motor. What I would try and do is unplug tool first and lay on its backside and try and blow all the dirt from the gears/slide assembly. Look for a broken part where the shaft goes thru and if none use a DRY LUBE spray and also check for proper meshing of the gears. After lubrucating while saw is laying on its back look at the gear for any possible binding. Set upright and try again.

ok thank you for reporting that your problem was solved.

Check the threaded rods that turn to move the motor assembly up and down. These rods are sometimes oiled or greased and this just attracts saw dust and eventually binds up the system. Clean as best you can and the threads they turn in to raise the blade. Also check the tilt rods.
Another thing to check is the joints everything pivots on. Occasionally a small peice of wood can get in just the right (or wrong) place and the motor assembly won't move because it's blocking the pivot points.

i would say the table is twisted then, strip it down first and if you need to "bend!" it back so it works
