Bosch table saw model 4000

My table saw started to make a high pitched sound and when it was turned off, i could easily spin the blade. Nowl, it doesnt want to spin, the blade locked up. Some one was saying it has to do with the motor, the bearings or brushes.When i turn the saw on, the blade wont spin.My saw is about 2 yrs old.

It sounds like the pinion on the armature and or gear are stripped. The only way to find out is to tilt the blade and remove the motor housing from the diaphragm and check it. If replacing the armature I would recommend also replacing the bearings and brushes as preventative

How do I keep the on switch of my Bosch PKS54 circular saw 'ON' without physically holding the on switch down?


Rewire the saw with a table mounted switch. This will probably void the warranty.

Which way do i turn the nut to loosten the blade on a bosch gcm 800s compound saw?


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.

Bosch table saw model 4000. Brushes where sparking alot .


It sounds like the armature is gone, if you are lucky the field coil is ok. Pull the back of the motor off and have a look at the armature where the brushes run if it looks burned or really rough the armature is gone and must be repalced.

Ihave a combination saw but do not have the instructions How do i change the blade


Hi
On the body of the Bosch saw there is a gray L shaped piece of metal. Push the metal in towards the saw. Rotate the blade by hand and you will feel it lock. Keep the metal depressed and turn the nut counterclockwise and remove the blade. Make sure power is disconnected. You can use a crescent or opened end wrench. Also the blade needs to be set at the maximum depth to easily remove the blade.

Have an old Black and Decker 7321 Skill Saw. Bought it used. Cant figure out how to change the blade. Help


With the saw UNPLUGGED, check around the base of the motor shaft, there should be some kind of button that you can depress to lock the blade from turning. Then with the appropriate sized wrench, turn the blade locking bolt clockwise (it is a backward thread) to loosen it. Then simply remove the washers, etc carefully and replace them the same way they came off. If there is no locking button, you can use a scrap piece of wood on the saw table and push down on the blade to lock it in place.

My 24v bosch cordless saw just quit working. Battery is good, the blade spins easily no electric smell occurred. It just stopped working. I am thinking the trigger, possibly brushes. Any thoughts?


If it is a new lithium ion, they just stop dead when the battery is dead and just needs to be recharged. If that is not the problem then it sounds like the battery is not connected to the saw very well, see it the connections inside the saw are bent or damaged in some way.
