DANGER
Do NOT use the manure spreader when brake system is unreliable.
5.3.2 INSPECTING AND CHECKING AIR TIGHTNESS OF PNEUMATIC SYSTEM.
Checking hydraulic system tightness
Connect the manure spreader to tractor.
Immobilise tractor and spreader with parking brake. Place chocks under
spreader rear wheel.
Start tractor in order to supplement air in manure spreader brake system tank.
In single line systems air pressure should amount to approx. 5.8 bar.
In double line systems air pressure should amount to approx. 8 bar.
Turn off tractor engine.
Check system components by releasing brake pedal in tractor.
Give particular attention to conduit 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 escape at the places of damage,
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. 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.
Checking tightness of pneumatic system:
•
after travelling the first 1,000 km,
•
each time after making repairs or changing system components,
•
annually.
