Crewsaver Mk5 Operating Head
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.

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.
