Fill in in a tank of a hydraulic actuator of coupling working liquid to the maximum mark and watch, that its level did not go down during operation performance. Remove a protective cap from the union for pumping on the main cylinder (fig. 4.5)
and put on the union a hose. Other end of a hose lower in the brake liquid poured in a transparent glass vessel. Slightly turn out the union for pumping, press against the stop a pedal of coupling and release it. Repeat this operation several times, the exit of vials from a hose will not stop yet. Wrap the union and put on it a cap. The same operation to execute on the working cylinder. After the completion of pumping of a hydraulic actuator of coupling be convinced of accurate work of a hydraulic actuator and the correct gear shifting in a transmission.
During pumping watch liquid level in a hydraulic actuator tank, without allowing an exposure of its bottom. The hose end for pumping should be constantly shipped in liquid.
