MSA R512539 Instructions D'utilisation page 15

The Rope Grab will work properly only when used with a lifeline meeting the specifications
-
supplied by MSA. Use of any substitute may result in serious injury or death.
Improper installation of the device on the lifeline will prevent free movement over the line and
-
prevent locking of the device on the line during a fall.
Never grasp a rope grab while moving. In the event of a fall, grasping a rope grab may interfere
-
with its fall arresting capabilities.
When working near the end of a lifeline, tie a knot at the end of the vertical lifeline to prevent the
-
rope grab from sliding off the end of the vertical lifeline.
Never tie a knot in the vertical lifeline between the anchorage and the rope grab as this may seve-
-
rely reduce the strength of the vertical lifeline.
Failure to follow these warnings may result in serious injury or death.
