3. Using the Compressed Air Breathing Apparatus
Warning!
The compressed air breathing apparatus may only be put into use in a
fully maintained and tested condition. If malfunctions or defects are
noticed prior to use, do not use the compressed air breathing apparatus
under any circumstances.
Get the apparatus checked and repaired by an authorised service
centre.
3.1. Prior to the First Use
Prior to the first use, the apparatus must be prepared for the number and types of
compressed air cylinders. Afterwards, when changing compressed air cylinders
(without attached bumpers) that have the same diameter, the closed loop of the
tension strap is increased or again tightened by opening or closing the tension
clamp. A readjustment of the length of the tension strap and a loosening of the
Velcro closure then is no longer required.
(1) Before installing the threaded handwheel, check that the O-ring inside the
handwheel high pressure socket is present and free of damage. If the O-ring
is damaged, it must be replaced before the SCBA is used.
(2) Thread the handwheel into the cylinder thread. The handwheel should be
hand-tight (no tools should be used).
