Adapting the facepiece

Facepiece wearers must each be provided with the facepiece size
suitable for them. In most cases, a facepiece of standard size M2 is
used. If leaktightness is a problem, facepieces sized S or L should
be used. Always make sure prior to use that the facepiece is
leaktight.
The sealing line between head and facepiece must be free of hair
and foreign substances as those may cause leakages. Special
hairstyles like ponytails should be avoided since the head straps
cannot be fitted properly. This might also result in leakages.
Spectacle wearers should wear facepiece spectacles.
● Install facepiece spectacles, if necessary

Keeping the facepiece ready

● Remove the protective film from the visor prior to first use.
● Check the facepiece prior to first use (see "Leak tests" on
page 10).
● Fully open the head harness.
● If necessary, put the neck support strap around the neck and
fasten it in retrieval position (Figure B).
1) Note the corresponding assembly instructions.

Donning the facepiece

NOTICE
With low temperatures, the equipment wearer can reduce facepiece
fogging by either inhaling or holding his breath when donning the
facepiece.
● Remove the facepiece from the retrieval position.
● Pull the head harness apart, then place your chin into the chin cup
(Figure C).
● Pull the head harness over the head and draw backwards.
● Adjust the facepiece.
● Stretch evenly tight; first the neck straps, then the temple straps,
finally the front strap (figure D).

Fit-checking the facepiece

● Put the lung demand valve of the SCBA in the connection piece.
● If available, close the button protector.
● Turn and pull the lung demand valve to check for tight fit. Have a
second person check the firmness and correct connection.
● Close the medium pressure hose with your thumb.
● Inhale, then hold your breath. No entry of air should be perceived,
otherwise check the fit of the facepiece. The exhaled air must
escape through the exhalation valve without resistance.
● Repeat the fit check twice.
● Connect the self-contained breathing apparatus.
