3.0 INSTALLATION
3.1 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 this manual.
3.2 ANCHORAGE: Figure 9 illustrates typical SRL anchorage connections. The anchorage (A) should be directly overhead to
minimize Free Fall and Swing Fall hazards (see Section 2). Select a rigid anchorage point capable of sustaining the static
loads defined in Section 2.2. The Swivel Eye on the SRL is equipped with a Carabiner (B). Attach the Carabner directly to
the anchorage structure (rebar, angle iron, etc.), a Tie-Off Adaptor (C), or Anchorage Connection Point (D).
3.3 HARNESS CONNECTION: A Full Body Harness is required for Fall Arrest applications. Connect the Snap Hook (A) on
the SRL Lifeline to the Back Dorsal D-Ring (B) on the Full Body Harness. (see Figure 10). For situations such as ladder
climbing, it may be useful to connect to the front Sternal D-Ring. Consult the harness manufacturer's instructions for
details regarding use of the harness connection points.
3.4 TRIPOD MOUNTING: Figure 11 illustrates installation of the Ultra-Lok Self-Retracting Device with Retrieval Hand-Crank
on a DBI-SALA Tripod. The SRL-R is mounted on a leg of the Tripod and the Lifeline is routed through a Pulley System on
the Head of the Tripod. See the instructions included with your Tripod and Mounting Bracket for details.
4.0 OPERATION
;
First time or infrequent users of Ultra-Lok Self-Retracting Devices (SRDs) should review the "Safety Information" at
the beginning of this manual prior to use of the SRD.
4.1 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. If there is any hesitation in retraction the unit should be
marked as "UNUSABLE" and returned to an authorized service center for service. Inspect the lifeline for cuts, frays, burns,
crushing and corrosion. Check locking action by pulling sharply on the line. See Section 5 for inspection details. Do not use if
inspection reveals an unsafe condition.
4.2 AFTER A FALL: Any equipment which has been subjected to the forces of arresting a fall or exhibits damage consistent
with the effect of fall arrest forces as described in Section 5, must be removed from service immediately, marked as
"UNUSABLE", and inspected and serviced as instructed in Sections 5 and 6.
4.3 BODY SUPPORT: A full body harness must be worn when using 3M SRLs. For general fall protection use, connect to
the back Dorsal D-Ring. For situations such as ladder climbing, it may be useful to connect to the front Sternal D-Ring.
Consult the harness manufacturer's instructions for details regarding use of the harness connection points.
4.4 MAKING CONNECTIONS: When using a hook to make a connection, ensure roll-out cannot occur (see Figure 5). Do not
use hooks or connectors that will not completely close over the attachment object. Do not use non-locking snap hooks.
The mounting surface should meet the anchorage strength requirements stated in section 2.2. Follow the manufacturer's
instructions supplied with each system component.
4.5 OPERATION: Inspect the SRL as described in section 5.0. Connect the SRL to a suitable anchorage or anchorage
connector as previously described. Connect the Self-Locking Snap Hook on the end of the lifeline to the Dorsal D-Ring on
the Full Body Harness (see Figure 10). Ensure connections are compatible in size, shape, and strength. Ensure hook is
fully closed and locked. Once attached, the worker is free to move about within the recommended working area at normal
speeds. If the RSQ Selection Knob is set to 'Fall Arrest', the SRL will arrest the fall. If the RSQ Selection Knob is set to
'Descent', the SRL will automatically descend the user to a lower level when a fall occurs. When working with an SRL,
always allow the lifeline to recoil back into the device under control. A tag line may be required to extend or retract the
lifeline during connection and disconnection operations. A tag line can be used to prevent uncontrolled retraction of the
lifeline into the SRL. Depending on the work site environment and conditions, it may be necessary to restrain the free end
of the tag line to prevent interference and entanglement with equipment or machinery.
4.6 RETRIEVAL OPERATION: Figure 12 illustrates operation of the Integral Rescue Hand Crank on the Ultra-Lok Retrieval
SRL-R. Do not attempt to operate Retrieval with the lifeline fully retracted. To activate Retrieval mode and use the Rescue
Hand Crank:
1. Pull out on the Retrieval Handle to release the Crank Arm.
2. Rotate the Retrieval Handle out from the SRL Body 180°.
3. Pull and hold the Shift Knob in the unlocked position.
4. Push the Crank Arm in and release the Shift Knob to engage. If needed, rotate the Crank Arm clockwise to help
engage the gear.
5. Raise and lower the Lifeline as illustrated in Figure 12:
A. To Raise: Rotate the Crank Arm counterclockwise.
B. To Lower: Crank the Crank Arm counterclockwise slightly to release the Fall Arrest Brake, then crank the Crank
Arm Clockwise..
;
The Integral Rescue Hand Crank on 3-Way Emergency Retrieval SRL-R models is for rescue purposes only and
should not be used for work positioning or material lifting/lowering.
