Simple way is to ensure you are tuned to a horizontal transponder before you move the dish - that way the motor's being supplied with 18 volts, instead of 13 volts (as it would be if you were last tuned to a vertical transponder).
I had an HH120 installed, but eventually got fed up with its slowness and switched over to a polar mount and linear actuator - much happier now!
