There are several steps:
Remove the base height adjustment lever assembly(#56,57,71,72,73,74)
Remove the lower blade guard (#37)
Remove the brushes (#810)
Remove the upper guard housing (#827)
The armature will usually slide out with the upper guard - once out wiggle the armature out of the guard housing.
Reverse order to reinstall

unplug saw
new Ryobi have a spindle lock button, it is unobtrusive and you may miss it

turn the motor housing slightly until you can put a screwdriver between the housing and diaphragm, pull on the one side and push with the driver and it will come apart, I just did one yesterday. To get the armature out of the fan bearing you will need a dead blow hammer to tap on the diaphragm while pulling on the armature. The bearing is held in place with 2 screws, hope this helps.

If you are mechanically inclined and it sounds that way do you have a volt ohms meter?? If so start at the cord and check the continuity to the brush holders. Why did you replace the field? You might have had a stuck brush or some other problem. Make sure the brushes move freely in the tubes and also look for discoloration on the commutator of the armature. Let me know what you find and I will try and help you thru the rest of it.

Need directions on how to pull out the Armature of BOSCH CS20 and convert it to 220volts internally?

Buy a second hand step down trafo 230v to 120v to made it a sheaper project , its not worth for this kind of handpowertools to customize it.

On marketing technical reasons, there are no equivalent components for this model cs20 the armature is look a like a Makita armature some type of bosch tools are comparable with parts in several variations. but little differences on measurements.

Jamie, Give saw time to re seat brushes, look for a bad (solder) connection where the winding is connected to the commutator bar if persist.

Could be the Armature itself (and the both bearings) and gear wheel bearings . worn tooth worm and ring gear remember if replace armature then also carbonbrushes bearings and drive gear with bearings

Then its working again in some cases if the color of the armature is bad then also measure of the electric field and look if its whether it is still firmly mounted.

How do you remove the blade guard on a bosch cs20?

counterclockwise in the same direction as the little arrow you show as the sawblade turns around. if you look at your handle look near that you will see on the metal part of the motor house a metal ,a 90 degrees bent metal bracket which protrudes, pust on this and turn slowly the sawblade then you feel on am short moment and push it as far as you can then its locking the blade , then you turn the bolt counterclockwise and The bracket itself bounces back.

Sparking at the carbon brush of circular saw every switched on.

the armature is shorting across the commutator bars and a new saw will be cheaper than a new armature

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.

I burnt up a circular saw trying to cut thick plywood with a dull blade and now it arcs when trying to use it. Is it repairable? Thanks.

I would replace the brushes on the motor, that is the first cause of arcing. The armature may be worn down too. Still a pretty easy inexpensive repair.
