Axle blocking
Each hydraulic cylinder is equipped with a spring accumulator, which causes the relevant axles to
spring.
CAUTION!
Use the function axle blocking only on a levelled and paved surface,
so the weight of the vehicle is distributed evenly over the wheels.
CAUTION!
Make sure when using the axle blocking, that all wheels are in contact with the
ground. All tyres must be curved (except possible retracted axles for the benefit of
a steering program).
This is necessary for not exceeding the maximum permissible axle load.
