User Warnings and Cautions
• Always wear your PFD when underway unless you are inside a cabin. This is a
requirement for commercial approval and is strongly advised for all users.
• This inflatable PFD must be worn and be serviceable to satisfy work vest requirements.
• Weak or non-swimmers should not use this device. In the case when oral inflation is the
only means to obtain flotation, a user must be able to keep their head above water long
enough to orally inflate the device.
• Do not use below freezing unless partially inflated. When the temperature is below
freezing, a fully discharged cylinder may not quickly or adequately inflate your Inflatable
PFD. Under these conditions use the oral inflator to adequately top-up the PFD, after CO
2
inflation.
• Do not fasten device to boat unless the attachment is capable of being pulled free, such
as a kill switch.
• Do not wear this device under clothing, as inflation under clothing will restrict breathing
or may otherwise injure you.
• Always have re-arm kits (MA7214) available to service your inflatable work vest.
• Check the date of the Inflator cap to ensure it has not expired.
• If you need to jump from any height, always fold your arms over your chest to keep the
PFD in place when entering the water.
