I think the gearbox on my Ozito SCMS-8MSS has failed. It hasn't had a lot of use and it's only 4.5 years old. It makes a screeching noise when the motor is running and the blade doesn't turn, nor does the shaft going through the blade. I want to take the gearbox assembly out so I can see what's gone wrong. I guess the gear has stripped completely or is spinning on it's shaft. I have taken the two screws/bolts out holding the bearing cover plate off and the locking pin and expected the gearbox assembly to pull out. Looking on the exploded parts diagram at SCMS-8MSS Mitre Saw; EX; AUS; - Spareparts / Accessories - Einhell Service (einhell-service.com) I can't see what is holding it in. But the image quality is not good. Does anybody know how to do it?
