225:. Standard operating instructions recommend that after travelling some miles on firm ground, the vehicle should be bounced over a curb or railway sleeper to lift wheels clear of the ground, one-by-one, to allow them to spring back and release the windup. Excess windup could easily lead to a broken gear in the bevel or hub gearboxes. To indicate this, white lines were painted across the ends of the hubs. Normally the lines should be parallel but as windup occurred they would become misaligned, indicating the need to release this.

When used for equally spaced wheels (i.e. rather than cargo trucks with close-set rear axles) the front two wheels are arranged so that both steer, the rear less so than the leading wheel. The varying track radii mean that when the vehicle drives in a curve on firm tarmac each wheel travels a
