SB 742-1
a. Shake manually.
If rattling sound is heard (M18
grenades with slurry starter mix only), smoke grenade is to be
considered serviceable, with restrictions (B01), (C06), (S05) and
defect classified as minor.
Engineering changes for M18
smoke grenades provided for the use of starter mix slug in lieu
of starter mix in slurry form. As a result, when grenade with
slug starter mix is checked for looseness (manually shaken)
there is a slight rattle. This is not a defect, but is inherent in
the M18 design. Starter mix slug was introduced into Pine
Bluff Arsenal lots as follows:
(1) 1330-G940 (Green) -- PB-89B013.... and after.
(2) 1330-G945 (Yellow) -- PB-89A033.... and after.
(3) 1330-G950 (Red) -- PB-88H055.... and after
(4) 1330-G955 (Violet) -- PB-88M072.... and after.
b. Feel where tape is covering emission hole to ensure
there has actually been a hole made in the metal container
underneath the tape.
