3. Check of inflation device before use
(quick check)
Each time before you put on the life jacket, check the opera-
tional readiness of the inflation device(s). To that end, open
the life jacket at the Velcro fastener or zipper and / or check
the inflation device through the inspection window.
Is indicator green? (see Figures 1 and 2)
In this case the life jacket is operational. If the indicator is
red, replace the CO
2
cartridge and make inflation device
ready as described in Chapter 8.
Repeat this inspection with the second inflation device of
your life jacket, if applicable.
After checking the inflation device and making it ready
again, if necessary, close the protection cover and make
sure the pull-cord for manual release hangs out freely from
the protection cover.
4. Check of life jackets before
each season / extended cruises
Open the press studs, Velcro fasteners or zippers of the life
jacket and unfold the buoyancy chamber.
Inflate the buoyancy chamber via the oral valve fully (also
refer to Chapter 6) and allow it to rest for approx. 16 hours.
If the buoyancy chamber is still full after this time, it is ok.
If your life jacket is provided with a second buoyancy cham
-
ber (e.g. SOLAS jackets), repeat this and the following steps
for the second chamber.
• Oral valve functioning?
Remove the dust cap and check the valve for operational
readiness using the inverted dust cap or the nose of the
dust cap see Figure 3. After pressing down the oral valve
with the dust cap and withdrawing it, the cap must close
completely. Install the dust cap again.
• Protection cover and straps undamaged?
Check the protection cover, webbing and fittings for da
-
mage and the existing accessories for completeness. If the
CLICK buckle does not close smoothly, apply some Teflon
spray to make it operational again.
Taking the life jacket out of service may be necessary, for
example, if the strength of the fabric and the straps is redu
-
ced by prolonged UV impact. This applies in particular to
life jackets with an integrated harness!
Life jackets with integrated harnes must be taken out of ser
-
vice (e.g. after a fall or chemical impact).
• Gas cartridge (CO
²
) o.k.?
Replace empty and corroded /
rusty gas cartridges with
new original SECUMAR spare cartridges.
Should you find any defects during the inspection, take your
life jacket to the SECUMAR SERVICE for maintenance in any
case (via authorized dealer or directly to manufacturer).
5. Putting on the life jacket
Always wear the life jacket on top of your clothing. Open
the buckle and put on the life jacket like a normal jacket
or pull over head in the case of closed models see Figures
5 and 6. Close buckle safely. Also refer to supplementary
operating instructions. Never wear the life jacket unfas
-
tened!
Adjust the body belt such that there is approx. 2
cm space
(two fingers) between your body and the belt. Only a tightly
fitting life jacket will keep you in a stable position on your
back.
If applicable, close the crotch strap and adjust it so that it
fits comfortably.
WARNING: Wearing the life jacket loosely or unfastened
is dangerous.
6. Inflating the life jacket
Life jackets with SECUMATIC 4001S automatic inflation
device:
When the user jumps into the water, the life jacket is inflated
fully automatically. Out of the water or if fully automatic
inflation fails, the inflation process can be started by pulling
the pull-cord firmly.
Life jackets with SECUMATIC 401S manual inflation
device: The inflation process is released by pulling the pull-
cord firmly.
Inflating via oral valve (tightness check)
/
refilling air:
Open the life jacket manually and blow up the buoy
-
ancy chamber via the mouth valve. To that end pull
off the dust cap from the mouth valve. When refilling
air via the mouth valve, avoid breathing in CO
² gas
from the buoyancy chamber (non-toxic, but may cause
coughing or dizziness).
7. Handling after use / making jacket
ready for use again
• Cleaning the life jacket.
Allow moist or wet life jacket to dry on a hanger or hang
from the neck part. Do not dry on a heating radiator! Re
-
move oil and grease immediately. Clean using a standard
commercial gentle washing detergent or mild soapsuds. Rin
-
se with clean water in any case. Note the care information
on the life jacket.
Do not use any alcohol or solvent containing cleaning
agents!
• Releasing air via the oral valve.
To release the air, remove the oral valve dust protection cap.
Press down the valve with the inverted dust cap or with the
nose of the dust cap (never use pointed objects). Press out
the air to empty the buoyancy chamber completely. After
emptying the buoyancy chamber, reinstall the dust cap see
Figure 3.
8. Making inflation device ready again
(re-arming)
After each use involving the inflation of the life jacket, the
inflation device must be made ready for use again. To do
that, you will need an original SECUMAR spares package
(re-arming kit).
Automatic inflation device SECUMATIC 4001S (see Figure 6)
• Remove empty cartridge from inflation device by turning
it through 90° and dispose of it. While doing this, push the
grey button in the direction of the arrow.
• If applicable, fold the manual release lever into the case
again, until it engages audibly.
• Fold tensioning lever B up. Warning: High spring loads! If
applicable, replace empty pill cage with new pill cage.
• Fold tensioning lever B down into the case again.
• Insert a new full CO
²
spare cartridge with green indi
-
cator into inflation device by turning it through 90°. The
size required (in g weight) is imprinted on the buoyancy
chamber.
Manual inflation device SECUMATIC 401S (see Figure 7)
• Remove empty cartridge from inflation device by tur
-
ning it through 90° and dispose of it. While doing this,
push the grey button in the direction of the arrow.
• If applicable, fold the manual release lever into the
case again, until it engages audibly.
• Insert a new full CO
²
spare cartridge with green indi
-
cator into inflation device by turning it through 90°. The
size required (in g weight) is imprinted on the buoyancy
chamber.
9. Interim replacing of the tablet
To replace the tablet (e.g. after use in environments with
high atmospheric moisture), please refer to the instruc
-
tions for making the inflation device ready for use again
(Chapter 8).
Please note: Always remove the CO
²
cartridge before actu
-
ating the tensioning lever.
10. Packing the life jacket
Release all air from the buoyancy chamber (see Chapter 7).
Close the oral valve with the dust cap (see Chapter 4).
Fold up life jacket following the instructions on the supplied
product information. Ensure that the inflation device is not
„wrapped up“. The buoyancy chamber must not be twis
-
ted. The white retaining straps must not be pulled together!
Close all press studs, Velcro fasteners and zippers carefully.
The manual release pull-cord must hang out of the protec
-
tion cover freely and be accessible. The straps must not be
twisted or knotted.
