Replacing the lens
Mask with metal lens frame: Grip the hexagonal

screws. Prise the lens frame apart with a
screwdriver at the connecting points, then pull it
off to the top and bottom.
Remove the support if necessary, see "Replacing
the facepiece connector".
Detach the old lens from its rubber frame.
Insert a new lens, first in the upper half and then
in the lower half of the rubber frame.
The center marks on the lens must be aligned
with the seam on the facepiece.
For masks approved for use in firefighting appli-
cations (class 3), only use lenses marked with the
letter »F« (Fire service). The »F« is marked at the
top of the lens.
Draw the rubber frame over the edge of the lens
on the right and left.
Moisten the outside of the rubber frame and the
inside of the lens frame with soap solution.
Fit first the upper, then the lower lens frame.
Fit the support if necessary.
Mask with metal lens frame: Screw the clamping
screws into the hexagonal nuts and tighten until
the gap between the clamp lobes is between 0.12
and 0.02 in (3 and 0.5 mm).
Mask with plastic lens frame: Insert and tighten
the screws.
Replacing the facepiece connector
Draw the nose cup out of the groove in the screw
ring.
Use a screw driver to pry open the connector
clamp.
Remove the connector clamp, sliding ring and
support.
Draw the facepiece connector out of the mask
body.
Insert the speech diaphragm and exhalation and
inhalation valves into the new mask connector,
and fit the connector so that the center marks of
the mask connector and mask body line up.
Mount slide ring and new connector clamp.
Attach the hook to ensure the tightest possible fit
of the connector clamp.
Push support between connector clamp and
slide ring, then attach it to the lower lens frame
and align (figure G).
Compress the nose on the connector clamp with
pliers R 53 239 until the facepiece connector is
securely located in the mask body.
Attach nose cup.
Replacing the valve discs on the nose cup valves
Pull out the old valve discs towards the inside.
Insert the stud of the new discs into the hole from
inside, and pull them towards the lens until the
undercut of the stud is visible.
The valve discs should make even contact with
the inside surface.
Replacing the speech diaphragm and O-ring
Draw the nose cup out of the groove in the screw
ring.
Unscrew the screw ring with socket wrench
R 26 817.
Turn the socket wrench over and carefully insert
it in the holes of the grille, taking care not to
damage the foil on the diaphragm.
Turn the speech diaphragm to release it and
remove it (figure H).
Remove the O-ring from the connector with seal
extractor R 21 519 or 40 54 983. Test the
speech diaphragm and O-ring and replace if
necessary.

Replacing the exhalation valve disc

Replacing the inhalation valve disc
Pull the inhalation valve out by its tab.
Remove the old valve disc, fit new valve disc.
Press the inhalation valve into the mask
connector until it makes even contact all-round.
