• Connect the hose to the control valve inlet. Fig 3.
• The mask is now being supplied with air and you can put it on.
• Use the regulator knob to set the air flow rate to suit your
current work intensity. Fig. 2.
In the fully closed position (turn the knob anti-clockwise), the
flow is about 5.3 CFM (150 l/min), and in the fully open position
(turn the knob clockwise), it is about 12 CFM (340 l/min).
• The breathing hose retaining clip which is supplied can be
used to advantage for securing the breathing hose to your
body. Fig. 1:11
2.5 Taking the equipment off
Leave the polluted work area before taking the equipment off.
• Remove the mask
Releasing the air supply hoses:
CEJN connectors
Push the coupling towards the nipple, at the same time pulling
the locking ring back. Fig. 4.
Schrader and Hansen connectors
Twist the locking ring on the coupling.
Releasing the breathing hose:
Push the coupling towards the nipple, at the same time pulling
the locking ring back. Fig. 4.
After every period of use, check that no defects have occurred,
and clean the equipment. See 4.1.
2.6 Cautions / limitations
A - Not for use in atmospheres containing less than 19.5
percent oxygen.
B - Not for use in atmospheres immediately dangerous to life
or health.
C - Do not exceed maximum use concentrations established
by regulatory standards.
D - Air-line respirators can be used only when the respirators
are supplied with respirable air meeting the requirements
of CGA G-7.1 Grade D or higher quality.
E - Use only the pressure ranges and hose lengths specified
in the User's Instructions.
J - Failure to properly use and maintain this product could
result in injury or death.
M - All approved respirators shall be selected, fitted, used, and
maintained in accordance with MSHA, OSHA and other
applicable regulations.
N - Never substitute, modify, add, or omit parts. Use only
exact replacement parts in configuration as specified by
the manufacturer.
O - Refer to User's Instructions, and/or maintenance manuals
for information on use and maintenance of these respira-
tors.
S - Special or critical User's Instructions and/or specific
use limitations apply. Refer to User's Instructions before
donning.
Do not use
− If the ambient air does not have a normal oxygen content.
− If the pollutants are unknown.
− With oxygen or oxygen-enriched air.
− If you can smell or taste the pollutants.
− If you finds it difficult to breath.
− If you experience dizziness, nausea or other types of
discomfort.
− If the warning whistle sounds, indicating that the air supply
is lower than recommended.
− If the functional check does not produce satisfactory results.
See 2.3.

Limitations
− A person working in an explosive or flammable environment
must follow any local regulations that may be in force for
such conditions.
− At very high work intensity, a partial vacuum may occur in
the equipment during the inhalation phase, which may cause
ambient air to be drawn in.
− The air supply system should be equipped with an appro-
priately rated and adjusted pressure relief safety valve.
− The equipment is approved only together with Sundström
compressed air supply hoses.
