EFFECTIVITY:
A heat-resistant braided cord is threaded through new line cutters to
provide safety during transport. Untie the cord and re-threaded
through the removed line cutters prior to discharge to absorb line cut-
ter blade energy and minimize discharged debris.
1
Remove braided cord from new line cutter. Retain new line cutter in a safe location
until required for installation.
2
Thread braided cord through removed line cutter's installation hole opposite ignition
loops. Tie ends of braided cord together securely.
CAUTION:
Too much pressure in vise clamp could damage line cutter and pre-
vent proper activation. Do not crush line cutter in vise clamp.
3
Insert line cutter into vise clamp with ignition loop positioned upward 45º, ensuring
line cutter is safely directed away from flammable materials.
4
Using pliers, carefully pull ignition loop from line cutter.
5
After audible “snap” is heard, record seconds between pulling ignition loop and firing
of line cutter. Be prepared for delayed activation. Typical activation duration is
approximately 8 seconds.
WARNING:
The line cutter can attain 1,100ºF (590ºC) during activation. Use
care when handling hot line cutters.
6
When cool, remove line cutter from vise and shake line cutter vigorously. Verify rat-
tle of loose spring can be audibly detected.
7
Verify portion of knife blade can be identified in gap between braided cord and cutter
hole edge.
8
Safely discard line cutter.
9
Repeat disposal procedure on remaining line cutter.

Installation - Pyrotechnic Line Cutters
(a)
Ensure safety pin is installed.
(b)
Verify three-link release assembly is correct.
(c)
Thread new nylon cord through mini-ring and pull cord ends equal.
(d)
Thread nylon cord ends through small link.
(e)
Thread one end of nylon cord through installation hole on first new line cutter.
(f)
Thread opposite end of nylon cord through installation hole on second new line cutter.
Note:
Use a short, thin piece of wire wrapped around the nylon cord ends to facili-
tate routing the nylon cord through the rear harness sleeve.
(g)
Wrap wire around nylon cord ends, insert wire into sleeve, and route cord through rear
harness sleeve.
(h)
Pull nylon cord completely through sleeve so mini-ring cinches up against top surface of
small link.
(i)
Position line cutters inside securing flaps and route nylon cord up, between link cutters.
(j)
With one end of nylon cord make one complete loop around mini-ring.
CAUTION:
Ensure no slack exists in nylon cord between rear harness sleeve and mini-
ring and line cutter installation holes and small link.
(k)
Cinch nylon cord tight.
(l)
Tie CAPS knot:
