Hi, my name is***** will be assisting you.
There is no bleeder valve that you can open to solve the problem.
First make certain that all of the hoses and lines going to the pump are tight and that you have nothing leaking where air might be drawn or sucked into the system. Then jack the rear of the machine up just high enough that the rear tires clear the floor and secure it with blocks or stands. Then you can start the machine and operate the drive control levers forward and backwards in slow motions to help to purge any air out of the system.
The key factor is to make certain that you have nothing loose or anything leaking that would allow for additional air to be drawn into or sucked into the system.
Thank you it has been a pleasure to assist you.
