Its Chad, I have an older Kees ZTMax, how do I go about changing my hydro oil. How do I know if there is no air in the lines?

Sorry Chad, Not familiar with this line. But you can go here;


Click on Search & Support then enter your model number to down-load the owner's manual which should have this service procedure listed. You will have air in the lines until you purge it out, And you will know quickly if there is still air in the system.
