11. Shut off engine. Connect pump control signal. Start engine, checking to be certain pump remains in
neutral. Run engine at normal operating speed and carefully check for forward and reverse control
operation.
12. Continue to cycle between forward and reverse for at least five minutes to bleed all air and flush
system contaminants out of loop.
Normal charge pressure fluctuation may occur during forward and reverse operation.
