Overview
An owner doing his own first 50-hour service on a Branson 5220R, covering both engine oil/filter and the full 9.7-gallon hydraulic-transmission fluid drain and filter swap. He calls out specific socket sizes (17mm, 11/16"), notes factory-tight filters, explains how he refilled and cycled the hydros to get the level right, and mentions the OTC 2352 hand pump as a key tool. Most useful to DIY owners preparing for this job.
