There is a procedure to purge the lines and cylinders but I don’t have the manual so can’t advise. I think first drain and refill reservoir, then change filter, followed by disconnecting a line from one side (return I believe) of each circuit and putting into a bucket, then running the pump for a few seconds will force the new fluid in and the old out. Otherwise if you don’t want to mess around with the lines, fill reservoir up half way, run each circuit up and down a couple times and change out the reservoir fluid again and you should be good to go.
