5.3.2 INSPECTING AND CHECKING AIR TIGHTNESS OF PNEUMATIC SYSTEM.
CHECKING HYDRAULIC SYSTEM TIGHTNESS
Hitch trailer to tractor.
Immobilise tractor and trailer with parking brake. Place chocks under trailer
rear wheel.
Start tractor in order to supplement air in trailer brake system tank.
In double line systems air pressure should amount to approx. 8 bar.
Turn off tractor ignition.
Check system components by releasing brake pedal in tractor.
Give particular attention to line connections and brake cylinders.
Repeat system check with depressed tractor brake pedal.
The help of a second person is required.
In the event of the appearance of leaks, compressed air will reach places of damage on the
exterior, with a characteristic hiss. Lack of system tightness may be exposed by covering
checked elements with washing fluid or other foaming preparations, which will not react
aggressively with system components. It is recommended to supply preparations
commercially available designed to facilitate discovering air leaks. Damaged components
should be replaced or repaired. If leaks appear at connections then tighten the connections. If
air continues to escape replace connection component or seal.
Check system tightness
•
after passing the first 1,000 km,
•
each time after making repairs or changing system components,
•
annually.
VISUAL ASSESSMENT OF SYSTEM
During tightness inspection attention should additionally be given to technical condition and
degree of cleanness of the system components. Contact of pneumatic line seals etc. with oil,
