RETRIEVAL OPERATION: Figure 11 illustrates operation of the Integral Rescue Hand Crank on Ultra-Lok
Retrieval SRL-Rs. Do not attempt to operate Retrieval with the lifeline fully retracted. To activate Retrieval
mode and use the Rescue Hand Crank:
1. Loosen the Locking Thumb Screw to release the Crank Arm.
2. Rotate the Retrieval Handle up from the SRL Body 90°.
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 11
A. To Raise: Rotate the Crank Arm clockwise.
B. To Lower: Rotate the Crank Arm counterclockwise. After fall arrest; crank the Crank Arm clockwise
slightly first to release the Fall Arrest Brake, then crank the Crank Arm counterclockwise.

RETRIEVAL OVERLOAD: Ultra-Lok™ SRL-Rs do not incorporate an Overload Clutch to limit the force exerted
on the drive components and attached person. Avoid line slack while in Retrieval mode. Also, monitor the
individual during retrieval to ensure they are not subjected to excessive force from continued lifting after
entanglement on an obstruction.
NOTE: A minimum load of 75 lbs (33.9 kg) is required to lower or pay out the Lifeline. A force of 30 lbs (0.13
kN) is required to operate the Retrieval system when loaded to capacity.
CAUTION: Stop cranking when the Lifeline is fully extended or retracted. Continued cranking can damage
components.
