MSA AirGo - Pressure Reducer with Alphaclick 2

GB
Using the Compressed Air Breathing Apparatus MSA
32 AirGo
(10) Briefly open cylinder valves and check for escaping air, retighten if
necessary.
(11) Tighten cylinder strap gently by pulling the free end.
Attention!
Do not overtighten the cylinder strap! Damage can occur when using
excessive force to close the cylinder buckle and the SCBA might not be
ready for use.
The final fastening tension will be achieved when closing the cylinder
buckle.
(12) Hinge cylinder buckle down until it catches.
(13) If push force/tension is too high during hinging of the cylinder buckle,
re-adjust the strap length at the cylinder buckle. If the strap tension is too
low, re-adjust the strap length at the cylinder buckle ( Fig. 19).
(14) Fasten end of the cylinder retaining strap onto Velcro strip.
(15) Check that compressed air cylinders are held securely, retighten if
necessary.
3.3.2. Pressure Reducer with alphaCLICK 2
(1) If necessary, thread the alphaCLICK 2 cylinder adaptor with a specific torque
of 20-30 Nm into the cylinder valve ( Section 5).
(2) Proceed as described from (1) to (5) for pressure reducer with thread
connection.
(3) Thread the cylinder valve onto the T-piece.
(4) Push a second compressed air cylinder through the cylinder retaining strap
so that the cylinder valve points to the T-piece and lies on the outer support.
(5) Thread the second cylinder valve onto the T-piece.
When fitting the T-piece with alphaCLICK 2 on the coupling of the
pressure reducer, it may tip down.
In this case, support the pressure reducer with your hand.
(6) Align the T-piece with the alphaCLICK 2 axially to the coupling and fit on the
alphaCLICK 2 coupling.
Attention!
Never push the coupling system together using excessive force.
(7) Close the coupling by pushing together using a "small amount" of force and
checking that the arrow of the indicator ring is vertically aligned with the back
plate.
