Fig. 3.2.3 Fig. 3.2.4
Fig. 3.2.2
Remove the operating head from the manifold which is
welded to the inflation chamber fabric. Inspect the
bottom sealing O-ring. This must be replaced with a new
part if damaged.
Unscrew the valve retaining nut from the top of the
operating head. Check for corrosion and discard if
corroded. Inspect the top sealing O-ring. This must be
replaced with a new part if damaged.
Unscrew the 60 gram cylinder from the automatic
operating head. Once the cylinder has been removed
inspect the cylinder O-Ring seal. Check the seal is in
place and that it is in a good condition. Take the cylinder
and check to see if the cylinder has been used. This
should be performed by check weighing. If under the
minimum weight as displayed on the cylinder body,
discard in a safe manner.
Fig. 3.2.1
Unscrew the Automatic firing capsule from the end of the
operating head. This should only be done after the test
detailed in Section 6 has been performed in order to test
the old unit, or if the operating head has already been
fired. Check the date stamp on the cylinder and discard
if expiry date is before the date of the next annual
service or the capsule has been fired and replace with a
new automatic firing capsule upon reassembly.

Take the new automatic capsule and screw onto the
operating head in a clockwise direction. Screw right
up ensuring there is no gap between the capsule and
operating head and then do up hand tight.
If fired manually replace the operating head arm into
the main body and fit the retaining clip. The clip is
fitted by pressing it over the firing arm and into the
recess either side in the centre of the operating head.
Check that the cylinder sealing gasket in the end of the
operating head has been correctly fitted, or replaced if
necessary. Check the new CO cylinder has not been
2
used and screw into the main body in a clockwise
direction. Ensure the cylinder is screwed right down and
do up hand tight.
The operating head is now rearmed.
