hydraulic system is required to operate the hydraulic braking system. The function of the
hydraulic solenoid valve (1) - figure (3.9) is to activate the trailer's brakes simultaneously with
the tractor's brakes. Before moving off, perform test braking by pressing brake pedal several
times in order to obtain proper pressure in hydraulic accumulators.

Connection lead (6) connects the trailer's brake valve with the tractor's electrical system. In
case of an inadvertent disconnection of the lead (6) between the trailer and the tractor, the
brake valve will automatically activate the trailer's brakes. The same emergency braking is
activated by switching off the tractor's engine or deenergizing the solenoid valve.
