1 | Choke the vehicle's wheels | In the case of no compressed air, the spring brake of the parking brake can be released mechanically. | |
2 | Unscrew the release bolt (2) from the normal position (A) until the mechanical releasing position (B) | With the system de-pressurized, a bigger effort will be necessary to unscrew the release bolt (2), but this effort should not be higher than the specified. | |
.Spring relief bolt - maximum | |||
3 | Pressurize the pneumatic system and release the parking brake | After pneumatic system is repaired, put combined cylinder (1) in operational conditions. | |
.Pressure regulator | |||
4 | Screw the release bolt (2) up to the normal position (A) | By pressurizing the spring cylinder via the connection 12, it will be possible to screw in the release bolt (2) manually. | |
5 | Apply the parking brake |
