follow the underlying surface without pressing too hard
against it.
Pressure is adjusted using a screw and spring on each side
of the Rider.

PSI.
2 Place the machine on a flat surface.

adjusting screws located behind the front wheels on both
sides. The ground pressure should be between 12 and 15
kg (26.5-33 lb).
