Tension Indicator
(Green and Red Rings)
1. Follow Procedures A through C of Section 4.3. Before continuing with Procedure D, prepare and install the second shock
absorber. See Fig. 9 for order of lifeline components when a second shock absorber is used.
2. Remove cotter pin, nut and bolt from anchor shackle.
3. Position anchor shackle through D-bolt anchor and align the shackle bolt holes with the eyebolt hole on the shock absorber.
4. Insert bolt completely through shackle and shock absorber eyebolt, attach nut and tighten snugly using a 3/4” wrench and
socket.
5. Insert the cotter pin into the end of the bolt and bend slightly to prevent the pin from backing out.
6. Follow Procedure D. NOTE: When taking up slack in the lifeline, however, allow sufficient lifeline to enable attachment of
the thimble to the shock absorber jaw.
7. Remove cotter pin and bolt from shock absorber jaw.
8. Position jaw over thimble and insert bolt completely through jaw and thimble.
9. Insert the cotter pin into the end of the bolt.

IMPORTANT:
It is essential that the lifeline be properly tensioned before use. Failure to do so will affect fall clearance re-
quirements and the potential fall forces which may be imposed upon the worker and the system.
4.4 Tensioning Horizontal Lifeline
1. To prevent the lifeline from twisting while tensioning, use an
open end wrench to hold the lifeline while rotating the shock
absorber body (drawing the jaw bolt threads and eyebolt
threads into the body) until the required tension is achieved.
NOTE: The shock absorber is equipped with tension indica
-
tors. When the lifeline is properly tensioned, a green ring will
be exposed where the shock absorber jaw bolt threads enter
and exit the shock absorber body.
WARNING: If a red ring is exposed, the lifeline is excessively
tensioned. In this case, loosen the lifeline by rotating the
shock absorber body in the opposite direction.
IMPORTANT: In environments in which thermal contraction and expansion can occur, it is important to perform initial
lifeline tensioning at peak temperatures. Inspection of the lifeline thereafter should also be done at peak temperatures.
2. Once the correct tension has been obtained, screw in the locknut on the lifeline side and lock it against the shock absorb-
er body with a 19mm open-end wrench and an 11mm wrench.
3. Proceed in the same way with the locknut on the opposite end of the shock absorber.
Before using the system, double-check all fasteners to ensure that they are installed correctly and to required specifi
-
cations.
