Failure to comply with following cautions and warnings
could cause equipment damage or personal injury.
WARNING: CLL and CLS cylinders are
NOT equipped with a stopring to retain

To prevent plunger over -
extension, a port is provided to vent the oil

becomes visible, the plunger is at maximum extension.
Further extension could result in the plunger being
forced out of the cylinder. See illustration 1 below.
