Hi! I have a Homier 4x6 bandsaw, model MBS46/03111. My hydraulic piston leaks (and might have air inside?) allowing the blade to drop down in little jerks rather than a smooth continuous slow motion. Are these pistons serviceable or should I be looking for a replacement? Any suggestions one where to get a replacement?

I think I had the same problem when I first bought the saw and got a replacement from Homier which is the one I am struggling with again now. Actually it has worked poorly for years and I'm just getting around to doing something about it after several recent frustrating uses.? I'm hoping there is a 3rd party replacement I can get. Any suggestions??
