Inspect the bottom sealing O-ring. This must be replaced with a new part if damaged.
3 Remove the protective cover and unscrew the retaining screw from the top of the firing head,
using the torque screwdriver. Check for corrosion and discard if corroded. Inspect the top
sealing O-ring. This must be replaced with a new part if damaged.
2 Unscrew the CO cylinder from the operating head. Once the cylinder has been removed inspect
2
the Cutter O-Ring . Check the O-Ring 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.
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. Discard and replace with a new automatic firing capsule
upon reassembly. The Capsule must be replaced if it expires before the date of the next annual
service.

6.1.1. Air Holding Test.
6.1.1.1 Connect through a suitable Tee piece and adaptor, the oral tube with the oral valve in the open
position, to a graduated water manometer (or a similar digital device for measuring back
pressure).
Note: Hammar inflators must be tested with the Hammar operating head fitted to the inflation chamber.
6.1.1.2 Slowly inflate the lifejacket from a regulated supply until manometer reads 200mbar
Warning: Regulated supply pressure must not exceed 20psi.
6.1.1.3 Close off the air supply and leave for 10 minutes to ensure pressure is stable.
6.1.1.4 Check and record the pressure and temperature reading on the Service Record Sheet.
6.1.1.5 Leave for 30 minutes.
6.1.1.6 Check and record the pressure and temperature reading on the Service Record Sheet.
The maximum difference in the two pressure readings (pressure drop) allowed is 10%. The
temperature differential shall be within plus or minus 3 degrees of the original reading. For each
degree Centigrade rise in temperature subtract 2.5 mbar. For each degree Centigrade drop in
temperature add 2.5 mbar to the readings to obtain the actual pressure variation. Should the
temperature variation be outside 3 degrees either way then the test shall be repeated.

6.1.1.7. If Lifejacket fails the Air holding test inspect as follows.
6.1.1.7.1 With the lifejacket inflated carefully brush or spray the surface with a weak solution of soap
and water or alternatively lower the lifejacket into a tank of water to observe for bubbles.
6.1.1.7.2 Identify and mark the source of leakage. Wash off in clean water and allow to dry naturally
in air.
6.1.1.7.2.1 Special Attention to be given to:
a) Manifold Schraeder Core
b) Oral Tube/ Top-up Valve
6.1.2 If the test is satisfactory deflate the Lifejacket in preparation for re-assembly. Refer to Section 8.
6.1.2.1. Insert the inverted oral valve dust cap into the top of the oral valve and expel the air. Do not use
vacuum pumps to deflate lifejackets.
6.2.1. Oral Valve.
6.2.1.1. When removing the test adapter from each oral valve check that the oral valve reseats. If in
doubt this may be checked by placing the valve underwater.
6.2.2 Schraeder Valve.
6.2.2.1 Should a leak be found in the Schraeder valve the faulty core must be removed and a new
valve inserted using the Torque Screwdriver from the tool kit.
6.3.1 Operational Test for Manual Operation.
6.3.1.1 Remove the operating mechanism from the lifejacket. With the cylinder also removed, pull the
lever on the side of the operating head, and check that the firing pin is visibly moving inside
the open end.
6.3.1.2 If the lever does not move, or the firing pin is not clearly moving, the operating head must be
replaced. Refer to Section 9 for part number.
6.3.2 Operational Test for Automatic Operating Heads (to be performed when capsules have expired).
6.3.2.1 Remove the operating mechanism from the lifejacket and remove the cylinder.
6.3.2.2 Assemble the expired capsule onto the body of the operating mechanism.
6.3.2.3 Place the complete unit into water and check that the unit operates within 5 seconds.
6.3.2.4 If the mechanism fails to pass repeat test replace the complete unit. Refer to Section 9 for part
Number of the replacement part.
NOTE: all failures of this test must be reported to Crewsaver. Crewsaver may require the
failed units to be returned. Please do not discard.
6.4.1 If the retro reflective tape shows any signs of degradation the following tests shall be carried out in
accordance with Marine Guidance Note MGN 105 (M+F) Issued by the UK Marine and Coast guard
Agency March 1999.
6.4.1.1 Place a new piece of the same retro-reflective material to, and on the same plane as, a
representative piece of material fitted to the appliance.
6.4.1.2 Pour water over both pieces of material.
6.4.1.3 Using a powerful torch or "Aldis" lamp held at eye level, compare the performance of the two
pieces
of material from a distance of 10 Metres.
6.4.1.4 If a noticeable deterioration in performance is observed then the retro-reflective material on the
appliance should be replaced.
6.4.1.5 Dry off the lifejacket before repacking.
6.5.1. Testing Procedure for lights fitted to lifejackets.
6.5.1.1 Crewsaver CSL Water Activated Light.
Test the light by immersing the sensor in water. The light must flash. Remove the light from the water and dry
it. The light must stop flashing. If the light does not flash the unit has expired and must be replaced.
