III. OPERATION & INSPECTION
A. GENERAL INSPECTION
•Before use, inspect device for loose fasteners, bent, cracked, distorted, worn, malfunctioning, or
damaged parts.
B. GENERAL OPERATION
WARNING: The following operation checkpoints and inspections must be done prior to each use:
1. Anchorage Connection:
Make sure the carabiner is properly seated and in the locked position
between the attachment swivel on the unit and the anchor point or make certain the unit is properly
installed in the Miller mounting device. The anchorage connector and anchorage point must be capable
of supporting 5,000 Ibs. (22kN) or meet OSHA 1926.502 requirements for a safety factor of two.
2. Lifeline Retraction:
With the device in the mounted position, test the lifeline retraction and tension by
pulling out several feet of the lifeline and allow it to retract back into the unit. Always maintain a light
tension on the lifeline as it retracts. The lifeline should pull out freely and retract all the way back into the
unit.
a. If the lifeline does not pull out smoothly or sticks when retracting, pull all of the lifeline out of the
housing and allow it to retract slowly under tension.
b. The lifeline should be checked regularly for signs of damage. Inspect for cuts, burns, corrosion, kinks,
frays, or worn areas.
c. Do not pull the lifeline out of the housing or let it retract while the unit is laying flat. Always inspect and
operate the unit in a mounted position.
3. Braking Mechanism:
The braking mechanism can be tested by grasping the lifeline above the load
indicator and applying a sharp steady pull downward which will engage the brakes. There should be no
slippage of the lifeline while the brakes
are engaged. Once tension is released,
the brakes will disengage and the unit will
return to the retractable mode.
4. Snap Hook:
Check the snap hook to
be sure that it operates freely, locks, and
the swivel operates smoothly. Inspect the
snap hook for any signs of damage to the
keepers and any bent, cracked, or
distorted components.
5. Snap Hook Load Indicator:
A load
indicator is located in the swivel of the
snap hook. The swivel eye will elongate
and expose a red area when subjected to
fall arresting forces as shown.
