12.5.8.5 Checking the pressure in the compressed air tank of the dual-circuit pneumatic
braking system (specialist workshop)
1. Connect a pressure gauge to the test connection on the
compressed air tank.
2. Run the tractor engine (approx. 3 mins.) until the compressed air
tank has filled.
3. Check whether the pressure gauge is displaying the setpoint
range 6.0 to 8.1 bar.
4. If the reading drops below or exceeds the setpoint range, have
the defective parts of the braking system replaced in a specialist
workshop.
12.5.8.6 Leak test of the dual-circuit pneumatic braking system (specialist workshop)
Test all connections, pipe, hose and screw unions for seal-
tightness
Eliminate any abrasion points on pipes and hoses
Replace any porous and damaged hoses (specialist workshop)
The dual-circuit pneumatic braking system is considered free of
leaks if the pressure drop within 10 minutes with the engine shut
down is no greater than 0.10 bar, i.e. about 0.6 bar per hour.
If the values are not maintained, have the leakage sealed or the
defective components of the brake system replaced at a
specialist workshop.
