The residual pressure thatis enclosed on the locking side ofthe cylinder can release the lockingfunction.• The cylinder must not be operatedwith external stops (e.g. shockabsorber, buffer, oil brake, etc.):– Itmaynotbepossibletoreliablyreach the internal end position.– The locking mechanism can wearout prematurely. (In the event ofpressure drop in the oppositechamber to less than the lockingpressure, the locking piston willprematurely fall to its endposition.)2010/02 – Subject to change Internet: www.festo.com/catalogue/...47
