Tutorial on Bleeding Air out of the Hydraulic lines: 16:45 - Warning - this is a very detailed, and targeted film. Not for everyone. This video is intended for hardcore hobby enthusiasts who are seeking out assistance, entertainment or a tutorial on how Hydraulics work. In this film I am working on the RC4WD "Earth Digger 2" Hydraulic Excavator, that is now "discontinued" - but still being sold at the time of this filming.
I offer helpful tips on bleeding the Hydraulic lines of air, and ensuring that your machine is working properly. I also identify all areas of the excavator, making it easier for you to understand. It took me a long time and many hours figuring this mammoth rc machine out - but its time to pass on some helpful hints, tips and tricks. When purchasing this machine, it does not come with an instruction book - and is marketed as an "advanced level RC". This video is here to help you.
