Bosch jigsaws use a bayonet fitting blade that is retained by a single screw located inside the quill accessed from the top by either a long slim screwdriver or hexagon key. Sometimes a plastic cap must be removed for access to the top of the quill and some models have an in-built release mechanism.

Can be an armature (field) problem if its an armature problem the machine sounds bad and becomes hot around the body in a short time in the most worse case, but a circuit board / switch problem can even be the problem But it does not happen that fast. Measure both field coils on the same resist and a balance over the electric commutator (collectors) of the armature Used on an generator ? Or was it overloaded ? Technical bad luck can also arise just like that, you first appeal to warranty

Beware on a high temperature that ruiin the motor house and can be bad in a very short time by the over-temperature of the electric field if it has no good RPM a bad armature to measure the collectors also measure there must be a balance between the 2 field coils of the electric field should be measured exact the same resistance . and all collectors measured between 2 over 2 also the same resist, if 1 or more collectors are bad then is there no balance in the armature and no driving speed without sparks. and its become hot in very strange situations.

Bosch does have a reasonable amount of spares available for their own models. I don't know whether Bosch have followed the trend of buying generic Chinese models and label engineering them to provide the market with cheaper models but a lot of "respectable" companies have with the result lots of otherwise reasonable tools from reasonable brands have few or no spare parts available. This might not affect you but it is something to be aware of as Bosch manufactured tools are generally of reasonable quality and not prone to such faults, except perhaps in isolated cases as happens to many manufacturers sometimes. If all the saws have the same fault it would indicate a design or manufacturing fault justifying contacting Bosch and making a complaint. Clearly someone must be nominated to dismantle one saw, unless under warranty, and discover the problem, list the parts needed and discover the cost and availability. If the parts aren't available it should be possible to repair broken parts, recondition worn or damaged parts, manufacture replacements or adapt other parts or methods to overcome the problem. It might be found, if the faults aren't identical, that parts from one machine might be used to repair another...

inspect the brushes as they wear rapidly for continued use and saw dust recondition the armature bars and fit new brushes

Are you asking about the armature in the motor?

Be sure to release (pull out) the bevel locking pin. I’m happy to assist further over the phone at https://www.6ya.com/expert/bill_f6ca18ca1db028ed
