FAQs | Robart Manufacturing
How much air pressure do I need in the air system to operate retracts?
Normal operating pressure is between 80 psi. - 110 psi. After checking pressure and gear, if your system is still not working properly you may need more air volume. Adding a larger air tank or a second air tank may cure the issue.
What kind of lubrication do I use in the air system components?
Use white lithium or silicone grease only. Using other oils or types of grease will destroy the “o”-rings in the air system and void the warranty. There are only 2 components of the Air System that will need further lubrication: 1. retract mechanism air cylinder “o”-rings, and 2. air control valve “o”-rings.
How do I diagnose an air leak in my air system or retracts?
In our website under “Support”, there is a troubleshooting guide on how to diagnose air leaks.
How do I send my Robart Retracts, RoboStruts, or Air System Components back for repair?
