Danger ! | 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 test kit | Required test connections: | |
Test kit | |||
2 | Lower the operating pressure in circuit 3 to approx. 7.5 bar | ||
3 | Start the engine and fill the compressed-air system until the pressure regulator cuts out | ||
4 | Switch off ignition | ||
5 | Check service pressures | Operating pressure of service brake circuits 1 and 2 | |
Operating pressure of auxiliary consumer circuits 3 and 4 | |||
If the required specified values are not reached: | |||
| |||
Replace 4-circuit protection valve (with integrated pressure limiter) (4.05). | |||
