2023 ZTS2 50 Hydra Gear Air Purge
 

My ZTS2 does not have remote reservoirs or bypass devices like its cousin ZT2. There’s a great YouTube video showing a ZT2 gear oil change. My Hydra gears are suffix ZH so ZT 2800/3100/3200 is the kit to use but I can’t find and info on air purge without the reservoir and bypass. Also I have read the pdf from HG and it only references the above procedure. Any help is appreciated
