• Insert the connector's bush into the adaptor cavity.

4.1.2 Cartridges
Apply finally the cartridges following the instructions that comes along with them and with the adaptor.
4.2 Donning
Elongate the straps of the headharness as much as possible. With both hands hold the neck and cheek
straps of the headharness, meanwhile widening them in order to be able to put your face into the mask. Once
your chin is in place, pass the headharness over your head, adjusting it so that straps are in the direction of
the facepiece buckles. Pull the straps until you feel a uniform yet comfortable pressure on your face along
the sealing flap. The buckles automatically lock into the required position. It is advisable to tighten the cheek
straps first, then the temple straps and finally the forehead straps (photographs 1, 2, 3 and 4). To loosen the
tension of the straps, gently lift the buckle tabs, which will make the strap slide backwards (photograph 6).
4.3 Check of pneumatic tightness
Before entering a contaminated atmosphere it is a good habit to check the tightness on the face and ex-
halation valve seal. Whilst wearing the mask, close the standard connector with the palm of your hand and
take a deep breath (photograph 5). The mask should slightly deform, adhering to your face more securely.
You should not notice any inward leakage of air from the outside. If you notice a leak, identify and eliminate
it immediately. After a satisfactory seal check, the mask can be connected to the filter or to the breathing
apparatus and the scheduled work can be carried out in total safety.
For TR 2002 CL2 TR 2002 CL3 and TR 2002 S CL3 with DUPLA adapter:
Whilst wearing the mask, close with the palm of your hands the vents of filters (if necessary help yourself
with two sheets of paper) and deeply breath-in. The mask should alter deform slightly, adhering to your
face more securely. You should not notice any inward leakage of air from the outside. If you notice a leak,
identify and eliminate it immediately.
