In single-line systems air pressure should be in range of 5.8 – 6.5 bar.
In twin-line systems air pressure should be approx. 6.5 bar.
Turn off the engine.
Release the brake pedal in a tractor and check the system components.
Pay particular attention to hose connectors and brake cylinders.
Press the brake pedal in a tractor and check the system components again.
Assistance of a second person is required.
In leaks are present, compressed air will get outside with a characteristic hiss. System
leakages may be also be detected by covering checked elements with washing fluid or other
foaming compounds which will not react aggressively with system components. It is
recommended to use commercially available compounds designed to facilitate discovering air
leaks. Damaged components should be replaced or repaired. If leaks appear near
connectors, user should tighten these connectors. If air continues to escape, replace
connector components or seals with new ones.
Control of tightness should be performed:
•
after first 1000 km,
•
after each repair or replacement of system elements,
•
once a year.
Visual inspection of the system
During tightness inspection attention should additionally be paid to the technical condition
and degree of cleanness of the system components. Contact of pneumatic lines, seals etc.
with oil, grease, petrol etc. may cause damage and accelerate the ageing process. Bent,
permanently deformed, cut or worn lines should be replaced.
Visual inspection of the system
•
Visual inspection of the system should be performed simultaneously with
control of the system tightness.
