Thomas, if it has a joy stick then it has a hoist control power unit it and therefore will be adjustable for speed and decent, I'm only familiar with the MR range of reach truck, if it has Zappy systems on this truck you will need a calibration tool to do the adjustments.
I'm sure someone on this site will have more information than I can supplie, as I am not familiar with the NR series.
