With the firing capsule fitted, fit the retaining clip. The clip is
fitted by pressing it over the firing arm and in to the recess
either side in the centre of the operating head. The clip will
click into place, thereby preventing the arm from moving.
The Crewsaver Mk5 and United Moulders Mk5 heads use
different retaining clips which are not interchangeable.

Fit the new firing capsule onto the operating head. Capsules fitted on
the Crewsaver Mk5 head are navy blue in colour. The capsule should
be screwed tight to the end. Make a note of the batch number and
manufacture date on to the service record sheet.
If the lifejacket is fitted with a United Moulders Mk5 head a M5i firing
capsule must be fitted. These are black in colour.
