	Loosen
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	*BA42.10-B-1005-08A
3	Pressurize the pneumatic system and release the parking brake	 After pneumatic system is repaired, put combined cylinder (1) in operational conditions.
		.Pressure regulator	*BE42.60-B-1001-01A
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
