Aha dirth inside mechanic or Oscillation has sharpened the blade holder axis due to the use of a wrong saw blade brand, such as possibly q-blades or equivalent brands. on marketing technical decision, the thickness and material behave of this blade in the working condition is that the grip on the shaft is become too sharp, so that the blade holder is no longer smooth, but there may also be a round locking ring at the top, which includes the mechanism, a bearing press can sometimes bring a solution, but a multimaster is not a supercut a multimaster often does not bring a solution in professional daily work, they are not for that and if you only stick to the Fein saw blades or another brand that has the exact same thickness and material of the saw blade, then this is very easy to prevent.

Greetings - The most common issue with this tool is the controller, next is the stator, then the armature. https://vserv09.fein.bawue.com/spc/index.php?r=item%2Flist&id=8141 You can use a simple continuity tester to see if the field (stator) is good by checking continuity in each winding. When the armature goes bad it is usually very obvious with a raised and burnt segment on the commutator - if this is the case you will need to replace the brushes as well. If the field rings out and the armature looks good I would replace the controller.
