ATTACH PRIMALINES TO M9 HOLDER.
a. Fill sandbag fully with loose dirt or sand and tie
b. Open M9 flap (1).
c. Place both primalines (2) into M9 by wrapping pri-
maline ends (3) behind M9, ensuring primaline ends
(3) leaving M9 lie next to incoming primalines (2).
d. Close flap (1) and push down to lock primalines (2)
If primaline ends overlap primalines, they
may interrupt initiation system rather than
setting off buried explosive charges.
e. Place sandbag on top of M9, ensuring primaline
ends (3) do not cross primalines (2).
f. Unwind shock tube (4) as you move to firing position with length of shock tube (4)
(about 24 m) and with remaining equipment. Upwind firing positions are preferable to
reduce debris fall out.
At night, cover both primalines with loose leaves, dirt or grass to help suppress flash.
