Turn off tractor engine.

Give particular attention to conduit connections and brake cylinders.
Repeat the 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 escape at the places of damage,
with a characteristic hiss. Lack of system tightness may be also detected 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 detecting 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 components or seals.
INSPECTION
•
After travelling the first 1,000 km.
•
Each time after making repairs or changing system components,
•
Every 12 months.
5.3.3 INSPECTION OF THE SYSTEM
INSPECTION
•
Each time during tightness inspection.
During tightness inspection attention should additionally be given to technical condition and
degree of cleanness of the system components. Contact of pneumatic conduit seals etc. with
oil, grease, petrol etc. may cause damage and accelerate the ageing process. Bent,
permanently deformed, cut or worn conduits should be replaced.
