WARNING: The fall arrest system MUST ONLY be connected to the back attachment element on the harness
provided for the purpose ("D" ring or webbing attachment extension). The D-rings on the belt and the ventral
anchorage point must only be used for the attachment of a work positioning or retaining system and never with
a fall arrest system.
WARNING: During use, check regularly the adjustment and/or attachment points.
is attached directly over the head of the
worker.

Horizontal systems and Tripods: It is
extremely important to ensure that the tripod
or the Horizontal line system is compatible with
the SRL. Horizontal systems must be designed
and installed under the supervision of a qualified
person only.
•
Sharp edges: The lifeline of the SRL may be
damaged by unprotected and sharp edges,
hence they should be protected from all edges.
The DEWALT Leading Edge tested Class 2 SRLs
are designed in such a way that they provide
additional protection from falls occurring over
edges. However, protection to these Class 2 SRLs
should be provided from sharp edges such as
sheared, cold rolled or flame cut steel.
