3M PROTECTA 3590500 User Instructions page 14

3.5 CONNECTING TO ANCHORAGE: Figure 7 illustrates typical SRD anchorage connections. The Anchorage (A) should
be directly overhead to minimize free fall and swing fall hazards (see Section 3.3.B). Select an anchorage capable of
sustaining the static loads defined in Table 1. Depending on system and product configuration, the user may secure the
Top Connector (B) of the SRD directly to the anchorage structure or to an anchorage connector or anchorage connection
point between.
3.6 CONNECTING TO A HARNESS: Connection of the SRD to a harness will vary per the harness and which attachment
element is used. See Figure 8 for reference. To secure, connect the Bottom Connector (A) of the SRD to the Attachment
Element (B) of the full body harness. For more information as to which attachment elements may be used, see the
manufacturer instructions of your harness.
;
The "Product Overview" specifies for which Fall Protection applications your SRD model may be used. Ensure use of
your harness complies with these requirements. A full body harness is required for Fall Arrest applications.
3.7 TRIPOD MOUNTING: Figure 13 illustrates installation of an SRD-R model on a Protecta Tripod. The SRD-R is mounted
on one leg of the tripod and the lifeline is routed through a pulley system on the head of the tripod. See the manufacturer
instructions for your tripod and mounting bracket for more information.
4.0 USE
4.1 BEFORE EACH USE: Verify that your work area and Fall Protection system meet all criteria defined in these instructions.
Verify that a formal Rescue Plan is in place. Inspect the product per the 'User' inspection points defined in the "Inspection
and Maintenance Log". If inspection reveals an unsafe or defective condition, or if there is any doubt about its condition
for safe use, remove the product from service immediately. Clearly tag the product "DO NOT USE". See Section 5 for more
information.
4.2 AFTER A FALL: If this equipment is subjected to fall arrest or impact force, remove it from service immediately. Clearly
tag it "DO NOT USE". See Section 5 for more information.
4.3 OPERATION: Before using an SRD, the worker will need to secure the SRD to an anchorage connection point and an
attachment element on their full body harness. Once secured, the worker may move within the established safe working
area at normal speeds. During use, always allow the SRD lifeline to recoil back into the device under control.
4.4 TAGLINES: Depending on the worksite and system configuration, the user may not always be able to reach the SRD at
its anchor point. In these situations, a tagline may be necessary. A tagline is a long piece of cord that loops through the
bottom connector of the SRD before looping back in on itself. When connected in this way, the user can raise or lower the
bottom connector of the SRD to their location by pulling on the tagline.
;
Ensure the free end of the tagline does not become entangled with other workers, equipment, or machinery. If
necessary, restrain the free end of the tagline.
4.5 RETRIEVAL OPERATION: The Retrieval Crank of an SRD-R may be used to raise or lower a suspended worker. To use
the Retrieval Crank, you must first engage Retrieval mode, then rotate the Crank. See Figure 12 for reference. To activate
Retrieval mode and use the Retrieval Crank:
1. Pull out the Crank Handle to release the Retrieval Crank.
2. Flip the Crank Handle out from the SRD body into its engaged position.
3. Pull and hold the shift knob in the unlocked position.
4. Push the Crank Arm in and release the shift knob to engage Retrieval mode. If needed, rotate the Crank Arm clockwise
to help engage the gear.
5. Turn the Retrieval Crank to either raise or lower the suspended worker.
A. To raise: Turn the Retrieval Crank counterclockwise.
B. To lower: First, turn the Retrieval Crank counterclockwise to release the fall arrest brake. Then, turn the Retrieval
Crank clockwise to lower.
;
Do not attempt to operate Retrieval mode when the lifeline is fully retracted. Stop turning the crank as soon as the
lifeline is fully retracted or extended.
;
The Rescue Crank is for Rescue applications only. Do not use for any other purpose.
;
3M SRD-Rs do not incorporate an overload clutch to limit forces exerted on the drive components and attached
person. Avoid line slack while in Retrieval mode. If the attached worker becomes entangled on an obstruction during
retrieval, ensure that the worker is not subjected to excessive force from continued lifting.
4.6 RETRIEVAL DISENGAGEMENT: The SRD-R should always be disengaged from Retrieval mode after use. To disengage
Retrieval mode:
;
When Retrieval mode is disengaged, the lifeline should fully retract into the SRD housing. To avoid possible injury,
either maintain control of the lifeline or retract the lifeline before disengaging.
1. Remove any load from the lifeline.
2. Pull and hold the shift knob in the unlocked position.
3. Pull the Crank Arm out to disengage, then release the shift knob.
4. Pull out and rotate the Crank Handle down toward the SRD body into its stowed position.
