Never exceed the maximum free fall distance specified for your Fall Protection equipment. Do not use any Fall Protection equipment that fails inspection, or if you have concerns about the use or suitability of the equipment. Contact 3M Technical Services with any questions.
Always ensure you are using the latest revision of your 3M instruction manual. Visit www.3m.com/userinstructions or contact 3M Technical Services for updated instruction manuals. PRODUCT OVERVIEW: Figure 1 illustrates the product models covered by this instruction. Self-Retracting Devices (SRDs) are drum-wound lifelines that retract into solid housings.
Before using this equipment, record the product identification information from the ID label in the ‘Inspection and Maintenance Log’ at the back of this manual. Table 1 – Product Specifications System Specifications: Anchorage: Anchorage structure requirements vary with the system application and whether it is a certified anchorage or non-certified anchorage.
Hazards may include, but are not limited to: high heat, chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp edges, or overhead materials that may fall and contact the user or equipment. Contact 3M Technical Services for further clarification.

MAKING CONNECTIONS: All connections must be compatible in size, shape, and strength. See Figure 4 for examples of inappropriate connections. Do not attach snap hooks and carabiners: To a D-Ring to which another connector is attached. In a manner that would result in a load on the gate. Large-throat snap hooks should not be connected to D-Rings or other connecting elements, unless the snap hook has a gate strength of 16 kN (3,600 lbf) or greater.
INSTALLATION OVERVIEW: Installing this product requires effective planning and knowledge of fall clearance requirements. In the event of a fall, there must be enough fall clearance present to safely arrest the user. 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.
Page 11
FALL CLEARANCE CHARTS Required Fall Clearance has been provided within the charts below. To determine Required Fall Clearance: 1. Locate your first connector (1). Measure the Anchorage Height (A) and Maximum Work Radius (W) of your connector, relative to the height of your D-ring. Place your first connector in the chart where these intersect. 2.

Figure 7 - Cab Mounting 3100247 3100084 3100247 3100084 STANDARD HARNESS WEB INTERFACE: See Figure 8 for reference. To mount the SRD on a Full Body Harness with SRD Harness Interface: Loosen the harness webbing. Pull out on the Web Straps (A) where they pass through the bottom of the Dorsal D-ring (B) until there is enough space to slide the harness web interface through.

Thread the first SRD onto the carabiner. Insert the Nose (E) of the carabiner through the Swivel Eye (F) of the SRD, then loop the SRD through to the Gate End (G) of the carabiner. Position the carabiner around the web straps. Insert the Nose (E) of the carabiner behind the loosened Web Straps (A), between the straps and the back pad of the harness.
