6. Adjust the full facepiece.
7. Stretch evenly tight; first the neck straps, then the temple straps, finally the
front strap.
3.4 Fit Check
NOTICE
If you use particle filter pads, always use the positive pressure test to check if
the mask fits tightly since the pad retainer does not seal the cartridge and the
pad base.
Negative pressure test (see fold-out page Figure D)
● Seal off both respiratory filters with your hands or an auxiliary means (e.g. a
plane cardboard) and inhale until negative pressure is produced in the
mask. Hold your breath for a short time.
The negative pressure is to remain. If not, tighten the headstraps again.
Positive pressure test (see fold-out page Figure E)
● Seal off the exhalation valve of the full facepiece and exhale. The full
facepiece must not lift off the face. If air escapes via the sealing frame,
tighten the headstraps again.
WARNING
Always make sure the full facepiece is airtight and that two respiratory filters of
the same type are fitted prior to entering a hazardous atmosphere.
If the performance of the full facepiece is impaired due to operation effects,
immediately leave the danger zone.
3.5 Duration of use
The operating period depends on various factors, including the type and
concentration of pollutant, type of respiratory filters and environmental
conditions such as temperature and relative humidity.

If the visor is damaged, leave the danger area immediately.
3.6.3 In explosion-hazard:

If the function of the mask is reduced by effects specific to the contaminated
area, leave the contaminated area immediately.
