Any hydraulic system works normally if air is removed from it.

During removal of air add only pure DOT 3 liquid recommended by the manufacturer.

PREVENTIONS Never use repeatedly liquid which flowed out from a hydraulic drive of coupling. Brake liquid is hygroscopic, that is absorbs moisture from air. Therefore the liquid, being stored in open ware, it is not recommended to use a long time.

At continuous leakages of liquid from a hydraulic drive or hit in hydraulic system of air define the reason and a place of leak and eliminate damage.

Air removal from a hydraulic drive of coupling make as follows (in the course of pumping watch that level of brake liquid did not fall below the middle of a tank of brake system):

Remove a protective cap from the pumping union on the working cylinder of coupling and clear the union.

Put on one end of a transparent hose the pumping union, the second end of a hose lower in the glass vessel filled with brake liquid on 5–7 see.

The assistant should press a coupling pedal, and at the pressed pedal unscrew on a turn half the pumping union.

Continuing to press a pedal, force out the liquid which was in system together with air through a hose in capacity. After the pedal will reach extreme bottom situation and the liquid effluence through a hose will stop, screw the pumping union home.

Repeat these operations, the air outlet from a hose will not stop yet.

Holding a pedal in the pressed situation, tighten the pumping union against the stop and remove a hose from the pumping union.

Wipe the union of pumping and establish a protective cap.
