The TO4 rotator and 1000mm bucket I purchased from Catsu Hydraulic seem to be very good quality and very good construction, but I am disappointed that the installation video and instruction manual received are for a larger rotator unit made for a heavier machine and consequently the rotator mentioned and highlighted in the two publications are different in construction and design. Hydraulic and electrical are different. I contacted the company representative Tomy Tan and he promptly sent a video send a downloadable instruction manual, but the manual was for a different rotator than mine. I reached back out to him again, and explained the problem. He is currently working on a solution. There is not yet any detailed YouTube videos showing the installation process for a TO4, so I am currently waiting for Tomys response.

Company representative, Tomy Tan was extremely helpful and made sure I was taken care of. I highly recommend buying from Catsu Hydraulic! Bob, in Nebraska USA
