Inspection and Maintenance Log (Table 2) at the back of this manual.

PRODUCT DESCRIPTION:

Figure 1 illustrates the 3M™ Self-Rescue™ Descent System.
Figure 2 identifies key components of the Self-Rescue Descent System (Self-Rescue System). The Self-Rescue System is a
harness mounted Backpack (A) containing a spooled Lifeline (B) feeding through a sealed Descent Device (C). The Lifeline
is terminated with an Easy-Link™ D-Ring (D) coupled to the exit port on the Descent Device. In an emergency, the user can
release the Easy-Link™ D-ring and initiate descent by pulling a Release Cord (E) mounted on the harness shoulder strap. If the
user is incapacitated, a rescuer can pull the Assisted-Rescue Ring (F) on the side of the Backpack with the accessory Rescue Pole
Kit (G) to release the D-Ring and initiate descent. A Mounting Pin (H) on the Descent Device Housing and two adjustable Clip
Straps (I) on the bottom of Backpack secure the Self-Rescue System to the Full Body Harness. A D-Ring Cover (J) on the top of
the Backpack snaps over the Harness Dorsal D-Ring to eliminate inadvertent use of the D-Ring. A Front Flap (K) and Back Zipper
(L) on the Backpack facilitate inspection of the Product Labels and internal components. See Figure 1 for available Self-Rescue
models and accessories:
