EXPLODING! Harbor Freight Bauer Random Orbit Polisher and its Undocumented Adjustable Counterweight!

In this video, I address how to prevent this tool's destruction, from improperly assembled screws, and describe its undocumented adjustable counterbalance that can minimize vibration. Please take a quick trip with me and save your Harbor Freight BAUER 7.5 Amp, 6 in. Long-Throw Random Orbit DA Polisher, SKU 56367 from ending up in the can! It is well worth the effort to pre-service this polisher as it seems quite well made but runs the Harbor Freight risk of poor assembly and terminal demise.
No mention of the adjustable counterbalance in the manual (it's pictured in the parts breakdown), but what a feature! Easily adjusted with the included Allen key from outside and requires no disassembly.
The other two Bauer tools that I am aware of that include the tachometer feedback RPM control are the BAUER 12 Amp, 7 in. Variable Speed Rotary Polisher/Sander, SKU 56792 and the BAUER 9 Amp Surface Conditioning Tool, SKU 58079.
