Page 12: Safety Information
Ensure there is adequate fall clearance when working at height. Never modify or alter your fall protection equipment. Only 3M or parties authorized in writing by 3M may make repairs to the equipment. Prior to use of fall protection equipment, ensure a rescue plan is in place which allows for prompt rescue if a fall incident occurs. -

Maintenance Log’ at the back of this manual. DESCRIPTION: Figure 2 identifies key components of the 3M™ DBI-SALA® Nano-Lok Wrap Back Self-Retracting Devices (SRD). Nano-Lok Wrap Back SRDs are Wrap Back webbing lifelines (J) that retract into a Nylon Housing (H). Nano-Lok Wrap Back SRDs include an integral Energy Absorber (I). - Page 14 . To avoid increased fall distances, do not work above the anchorage level. Do not lengthen SRDs by connecting a lanyard or similar component without consulting 3M. Never clamp, knot, or prevent the lifeline from retracting or staying taut. Avoid slack line.
- Page 15 Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked. 3M connectors (snap hooks and carabiners) are designed to be used only as specified in each product’s user’s instructions. See Figure 6 for examples of inappropriate connections. Do not connect snap hooks and carabiners: To a D-ring to which another connector is attached.
- Page 16 3.0 Installation PLANNING: Plan your fall protection system before starting your work. Account for all factors that may affect your safety before, during, and after a fall. Consider all requirements and limitations defined in Section 2. ANCHORAGE: Figure 9 illustrates typical SRD anchorage connections. Select an anchorage location with minimal free fall and swing fall hazards (see Section 1).
- Page 17 4.0 Use BEFORE EACH USE: Before each use of this fall protection equipment carefully inspect it to assure it is in good working condition. Check for worn or damaged parts. Ensure all bolts are present and secure. Check that the lifeline is retracting properly by pulling out the line and allowing it to slowly retract.
