5.3.2 TIGHTNESS CHECK AND VISUAL INSPECTION OF THE INSTALLATION
Checking the tightness of pneumatic systems
Hitch trailer to tractor.
The tractor and trailer should be immobilized with the parking brake.
Additionally, place wedges under the wheel of the trailer.
Start the tractor to supplement the air in the trailer braking system tank.
In single conduit systems air pressure should amount to approx. 5.8–
6.3 bar.
In double conduit systems, the air pressure should be around 6.5- 8
bar.
Switch off the tractor engine.
Check the system components with the tractor brake pedal released.
Pay special attention to cable connections and brake cylinders.
Repeat the system check with the tractor brake pedal depressed.
The help of another person is required.
In the event of a leak, the compressed air will leak out in places of damage with a
characteristic hiss. The system leak can also be detected by coating the checked elements
with washing liquid or other foaming agent, which will not aggressively affect the elements of
the installation. It is recommended to use commercially available preparations intended for
leak detection. Damaged elements should be replaced or sent for repair. If the leak appeared
around the connections, the user can tighten the connector on their own. If air still leaks,
replace the connector components or seals with new ones.
Checking the installation for leaks:
•
after covering the first 1,000 km,
•
each time after repair or replacement of system components,
•
once a year.
