(3) Place the quick release into the vise with
the chest straps located at the top, the leg straps at the
bottom, and the operating button centered between the
vise jaws (fig. 2-5). Tighten the vise to a snug fit which
should require 4- to 5-pounds of force applied with an 8-
inch-long handle for leverage.
Figure 2-5. Quick release positioned in vise, typical.
During application of the pull-test, all
references to direction (right, left,
top, bottom, rear) are presented as
rigger's view when positioned to the
side of a quick release contained
within a vise.
(4) Grasp the right chest strap firmly with
both hands as close as possible to the harness lug, and
apply a steady hard pull toward the rear of the quick
release (A, fig. 2-6). Maintaining a steady hard pull,
alternate the direction of pull force 6 inches to the left
and 6 inches to the right (B). Apply the alternating pull
action six times without releasing the strap.
