(a)
Inspect top case half.
1.
There should be one triangular rubber pad and one round rubber pad on inside of top case half (5).
2.
Remove millibar knob (8) and ensure that O ring (9) is present and serviceable.
NOTE
Due to the ability of the neoprene rubber bush seal to retain a set position ("memory
characteristic"), once the arming pin has been inserted it is virtually impossible for the
seal to achieve a total seal after it has been used If the slit opening is doubtful, it should
be replaced.
(b)
Inspect bottom case half.
1.
There should be two round rubber pads on inside of bottom case half (6).
2.
Ensure the reset indicator window (10) is present and not broken.
3.
Point bottom case half (6) toward a light source to ensure that no light penetrates through arming pin
guide bush seal (11).
(c)
Replace rubber pads, arming pin guide bush, or arming pin guide bush seal as required. (Replace arming
pin guide bush seal in accordance with REPAIR function below)
(5)
Inspect Firing Mechanism.
CAUTION
Never permit the firing mechanism to lay on its millibar dial Damage to mechanism may result
NOTE
Change the rubber seal whenever unserviceable or every 25 operations, whichever
comes first
Unused rubber seals must be stored in a sealed plastic bag at all times.
When replacing rubber seals, ensure that flat portion of rubber seal is aligned with flat
side of firing mechanism.
