3.3. Production of air from the coupling drive

Only for coupling with a hydraulic actuator

It is necessary to let out the air from the drive only if the pedal of coupling does not come back to a starting position or comes back with a delay, or the hydraulic system opened. Previously to check ease of the course of a pedal on a finger and to a servopruzhin.

The hydraulic system of coupling uses brake fluid and has the tank of brake fluid, general with the brake system.

The production of air from hydraulics of system is made by means of the device of production of air from the brake system which, as a rule, is available only on HUNDRED. The device of production of air creates through a tank of brake fluid pressure upon brake fluid (max. – 2,5 bars).
