Technical Specification; Maintenance Schedule; Spare Parts - Sundstrom SR 580 Mode D'emploi

Breathing hose
One end of the hose has a ø42 mm thread (fig. 1b/2b), whilst
the other is fitted with an O-ring (fig. 1c/2c). The threaded end
is to be connected to the helmet.
2.4 Putting the helmet on
Also see the user instructions for the SR 500/SR 500 EX/
SR 700 fan and the SR 507 compressed air attachment,
whichever is used.
• Check that the 6-point harness is secured correctly (fig. 9).
• Raise the visor and put on the helmet (fig. 10).
• If necessary, adjust the width of the helmet using the knob
located at the rear of the harness (fig. 11).
• To adjust the height of the helmet interior, move the pins
between positions a and b (fig. 12). If the interior is attached
to pin a, the helmet will sit lower, and on pin b the helmet
will be higher. To achieve the best fit, this adjustment can
be made at both the front and back of the helmet.
• Lower the visor by pulling the face seal down below your
chin. A 'click' indicates that the visor is fully lowered (fig. 13).
• Insert a finger inside the face seal and move it along the
length of the contact surface to check the fit (fig. 14).
• Make sure that the breathing hose runs down your back
and is not twisted. You can adjust the angle of the helmet
connection as required (fig. 15).
2.5 Removal
See the user manual for the SR 500 /SR 500 EX/SR 700 fan
and the SR 507 compressed air attachment, whichever is
going to be used.

4. Maintenance
The person responsible for cleaning and maintaining the
equipment must have suitable training and be well acquainted
with work of this type.
4.1 Cleaning
Sundström cleaning tissues SR 5226 are recommended for
daily care.
If the equipment is more heavily fouled, use a soft brush or
sponge moistened with a solution of water and dishwashing
detergent or the like. Rinse the equipment and leave it to dry.
N.B. Never use a solvent for cleaning.
4.2 Storage
After cleaning, store the equipment, dry and clean, at room
temperature. The SR 580 should be stored with the visor either
fully raised or fully lowered. Keep out of direct sunlight.

4.3 Maintenance schedule

The following schedule shows the recommended minimum
maintenance procedures required in order to ensure that the
equipment is always in functional condition.
Before use
Visual inspection
Performance check
Cleaning
Replacement of hose O-ring
Replacement of gasket
in helmet
Replacement of
exhalation membrane
At the first signs of wear, impact marks, damage or aging of the
material, the helmet shell or harness must be replaced in order
to ensure the protective ability of the helmet is maintained. This
must be checked on a regular basis.
A helmet that shows signs of damage, e.g. cracks or scratches,
that may reduce its protective ability must be discarded. The
helmet must also be discarded if it has been exposed to
stresses during an accident or near accident, even if there is
no visible damage.
The helmet should be used within 5 years after the date of
production or within 3 years of being taken into use, whichever
of these dates is the earlier.

4.4 Spare parts

Always use Sundström genuine parts. Do not modify the
equipment.
Use of non-genuine parts or modifications may reduce pro-
tective function and put at risk the approvals received by the
product.
4.4.1 Replacement of exhalation
membrane
The exhalation membrane is fitted on a pin inside the valve
cover. The cover must be replaced at the same time as the
membrane. Do the following:
• Remove the valve cover from the valve seat (fig. 16).
• Pull out the membrane.
