INSTALLATION STEP 9
Attach the Emergency Release Rope
and Handle
Thread one end of the rope through the hole in the top
of the red handle so "NOTICE" reads right side up as
shown. Secure with an overhand knot at least
1" (2.5 cm) from the end of the rope to prevent
slipping.
Thread the other end of the rope through the hole in
the release arm of the outer trolley.
Adjust rope length so the handle is 6 feet (1.8 m)
above the floor. Ensure that the rope and handle clear
the tops of all vehicles to avoid entanglement. Secure
with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.
