8.5 Replacement of Collar (only required if the nylon cape is used)
The inner collar plays an important roll in controlling air escape from the helmet and preventing ingress of
dust. To replace or wash the collar it has to be detached with the zip from the cape (see point 9 for service
maintenance and cleaning).
The cape must be replaced when the collar is stretched to the point where it no longer fits snug
around the neck.
8.6 Replacement of Lens Frame
The lens frame must be replaced if a sealing is not ensured anymore or if the rubber latch
doesn’t stay
closed. When changing the lens frame the silencing in the inner part of the helmet should be changed, too.
8.7 Replacement of Chin Strap
The chin strap must be replaced at the first sign of wear.
To get the chinstrap off the holder push it up into the helmet till it snaps out, then take it off the holders.
When replacing the new chinstrap look to it that the bevelled side shows to the centre of the helmet.
9 Service Maintenance and Cleaning
Follow washing instructions described in this section. Do not use any caustic chemicals or sol-
vents that may be irritating or harmful to the user, or which change the properties of the materials
used in any part of the respirator.
9.1 Filter
The filter (foam) is in the air control valve. Replace the foam filter at the first sign of soiling.

reassemble these 3 parts in opposite order.

bleach are not allowed.)
