5)To check the oral inflation valve, fully inflate PFD and hold valve under water. If bubbles appear, deflate and reinflate to test again. Should the leak persist, take your inflatable PFD to your
dealer for proper servicing.
6)Visually examine your PFD for damage or excessive abrasion, wear, tear or contamination. Particular attention must be paid to the stitching. If in doubt, send it to your Mustang dealer for evaluation and/or servicing.
7)Reassemble inflation system parts and repack PFD as outlined in previous instructions and illustrations.
Leak test: Every three months the PFD should be tested for
general leakage by orally inflating your inflatable PFD until firm and let stand overnight. A leaking PFD will not hold its firmness and should be replaced.
Warning: If you are not confident in the self inspection and servicing of your PFD, in accordance with these instructions,
take your inflatable PFD to a Mustang dealer for professional
servicing or contact Mustang Survival (see contact information on back of manual).
