Nice work ! So i watched the entire video. I don't what i missed. What actually kept the tool from operating? I have 3 of these down at my shop and Im sure I checked everything. Ive checked and replaced switches, new brushes, new electic motor, ive changed a control board and still nothing. I have the green light but the tool will not operate. Any insight would be appreciated.

@powertoolsclinic Thankyou !

Welcome! How to measure stationary and rotating parts? I'm sure the engine is faulty, but I don't know which part!

[@powertoolsclinic]

What problems with your machine?

[@MrBocsa]

@@powertoolsclinic This is a Makita HM1307C Demolition Hammer! The problem is that it won't start! The green LED on the controller lights up, but the engine does not start! I replaced the controller, but the controller is not the fault!! I connected 12V to the brushes and the engine started! I measured the stator with an ohmmeter, without a brush holder! There is resistance between only 2 outputs, nothing can be measured between the others! Maybe one of the coils is broken?

[@powertoolsclinic]

Check the carbon brush if the carbon brush is short Replace it with the new one for the good of your machine Replace all O rings and Hammer grease inside the machine but if you don't know how to Disassemble contact your local Makita distributor or dealer in your country thanks

[@MrBocsa]

@@powertoolsclinic I solved the problem! There are two coils in the stator, one is broken! Thank you for your reply!

[@powertoolsclinic]

Carbon Brush is short or worn-out

[@michaelhaze4507]

Makita or Dewalt? which is most powerful?

[@powertoolsclinic]

For me makita not only powerful but availability of genuine spare parts
