Warning | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
| Check | ||
1 | Connect pressure gauge to test connection M16x1.5 (38.02) of compressed air reservoir for circuit 1 or circuit 2 | Test kit | |
2 | Operate brake pedal several times in a row to lower the reservoir pressure to approx. 8 bar | Only if the compressed air system is already filled completely. | |
3 | Start the engine, fill compressed air system and observe pressure gauge until pressure regulator blows off through the ventilation at the compressed air drier | The shutoff pressure is the pressure at which the pressure regulator blows off through the ventilation on the compressed air drier. | |
Pressure regulator shutoff pressure | |||
If there are problems | |||
| |||
Set shutoff pressure for pressure regulator. | |||
Adjust | |||
4 | Turn off engine | ||
5 | Adjust the shutoff pressure of the pressure regulator by screwing the adjustment screw (1) in or out | Pressure regulator shutoff pressure | |
6 | Run through operation steps again for checking shutoff pressure | ||
| Check | ||
7 | Let engine idle after reaching shutoff pressure | ||
8 | Unfasten union nut from hose of pressure gauge on test connection M16x1,5 (38.02) far enough until the reservoir pressure slowly drops off | ||
9 | Observe pressure gauge until it no longer blows off through the ventilation on the compressed air drier and read off the cut-in pressure on the pressure gauge | The cut-in pressure is reached when the pressure regulator switches over, i.e. does not blow off through the ventilation on the compressed air drier. | |
Pressure regulator cut-in pressure | |||
If shutoff pressure is correct and there is a problem with the cut-in pressure | |||
| |||
Install new compressed air drier. | |||
10 | Turn off engine | ||
11 | Disconnect pressure gauge and hose of pressure gauge from test connection M16x1.5 (38.02) |
