.
The time from the moment of pressure drop at the connecting head level to 90% of the initial
value until the moment, at which the pressure in the trailing vehicle actuator being in the least
favorable conditions reaches 75% of the steady-state value with the control member being fully
operated, shall not exceed 0.4s;
d) the total weight of the load being conveyed including the trailer shall not exceed 36 t.
During motion of the tractor with all kinds of vehicles use the fuel feed pedal setting the manual
