Check system components by releasing brake pedal in tractor.
Pay 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 detected by covering checked
elements with washing fluid or other foaming preparations, which will not react aggressively
with the system components. It is recommended to use 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 with new ones.
Check system tightness
•
after travelling the first 1,000 km,
•
each time after making repairs or changing system components,
•
annually.
Visual inspection of the system
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.
Visual inspection of the system
•
Conduct inspection of system at the same time as when checking tightness.
ATTENTION
Repair, exchange or regeneration of pneumatic system components may only be
performed in a specialised workshop.
