Beschreibung
Zusammenfassung:	A manual override device for controlling at least one valve in a power system includes a rod having a first end and a second end. An attachment is configured to attach to a spool of the at least one valve and includes a clearance with respect to the first end of the rod so as to allow the attachment to move with the spool, during ordinary operation of the power system, without contacting the rod. A lever is connected to the second end of the rod and is configured to activate the manual override device by moving the rod in a longitudinal direction such that the first end of the rod makes contact with the attachment to move the spool.
