Testing
The mask must be tested whenever it has been used, serviced or
repaired.
Test equipment and accessories: Testor
R 53 345.
Check for leaks: Note the Instructions for Use of the "Testor". Moisten
softbody with water if necessary and fit mask on test head; see "Putting
on the mask". Inflate the test head until the softbody fits snugly all
round. Seal the facepiece connector with the adapter and produce a
vacuum of 10 mbar. The mask is deemed to be tight if the pressure
changes by no more than 1 mbar after 1 minute. Otherwise, see
"Check for leaks underwater".
Check for leaks underwater: Remove earphones and microphones if
fitted. Immerse test head with mask in water. Produce an excess
pressure of approx. 10 mbar and slowly rotate the test head under the
water surface. Any leaks are revealed by air bubbles emerging from the
test head. Remove the test head and mask from the water, seal any
leaks and repeat the test.
After testing: Press the button and remove the adapter. Remove the
mask from the test head and dry it if necessary.
Headset: Assemble the microphone, headphone and earpiece; see
"Special maintenance work".
Special maintenance work
Assembling the headset:
1 Fit earpiece.
2 Secure headphone to straps.
3 Secure headphone to softbody by means of
the clamp.
4 Screw in the microphone.
Replacing the visor: Undo the two clamping
screws. Prise the clamping frame apart with a
screwdriver at the connecting points, then pull
it off to the top and bottom. Remove the sup-
port if necessary. Detach the old visor from the
rubber frame.
Mask with wiper: Remove the wiper from the
old visor and fit it onto the new visor.
If approved for use by the fire service: Only use visors marked "F" (fire
service). The letter "F" must be at the top.
Insert the visor first in the upper and then in the lower part of the rubber
frame. The centre marks on the visor should be aligned with the seam
on the facepiece. Draw the rubber frame over the edge of the visor on
the right and left. Moisten the outside of the rubber frame and the inside
of the clamping frame with soap solution. Fit first the upper, then the
lower clamping frame. Fit the support if necessary. Screw the bolts into
the hex nuts and tighten them until the distance between cams 3 is
approx. 0.5 mm.
Replacing the facepiece connector: Draw the
inner mask out of the groove in the screw ring.
Prise open the clip with the aid of a screw-
driver. Remove the clip, sliding ring and
support. Draw the facepiece connector out of
the faceblank. Place the speech diaphragm in
a new facepiece connector and insert it so that the centre marks on the
facepiece connector and faceblank are lined up. Fit the sliding ring and
new clip. Engage the hooks so that the clip is as tight as possible.
Slide the support between the clip and sliding
ring; attach it to the lower clamping frame and
align it. Compress the nose on the clip with
pliers R 53 239 until the facepiece connector
is securely located in the faceblank. Fit the
inner mask.
Replacing the valve discs on the inner mask control valves: Pull out
the old valve disc towards the inside. Insert the stud of the new disc
into the hole from inside, and pull it towards the visor 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 inner mask
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. Remove the O-ring
from the connector with seal extractor
R 21 519. Check the speech diaphragm and
O-ring and replace if necessary.
When assembling the parts: press the edge of the inner mask into the
groove in the screw ring and ensure that it engages all round. The
centre marks on the facepiece connector and on the inner mask must
be lined up.
Only use original Dräger parts. Leakage tests must be repeated
after maintenance work and/or after replacing components.
