10.3. Pumping of a hydraulic actuator of coupling


Work is carried out on the elevator or a viewing ditch.

We check liquid level in a tank of a hydraulic actuator of coupling and if necessary we add liquid.

We remove a cap from the union of the working cylinder.

We put on a transparent plastic hose which end is lowered in the container with brake fluid the union.

Key "on 8" we unscrew the union on 1/2–3/4 turns.

At the same time the assistant sharply presses a pedal of coupling and smoothly releases until the vials of air allocated from a hose disappear.
At the pressed pedal of coupling we wrap the union, we remove a hose and we put on a cap.
