ADJUSTMENT - 2nd STAGE 1133, 3224, 3354, 3354 M, 3536
Open the LP valve. Check the secondary
pressure. It should be around 11.5 bar
(166 psi). Max tank pressure should be used.
Check to make sure that the clearance between
the control unit and the low pressure valve is
approximately lmm. See ill. A. If the clearance is
too small, do not seal the second stage valve. If
the clearance is too large, reduce the flow of air
and the inhalation resistance will increase.
Adjustment of the clearance:
Close the LP valve, and empty the regulator
completely by means of the purge button.
Unscrew and remove the low pressure hose from
the second stage valve.
If the clearance is too small, screw the valve seat
inwards (clockwise) using an 8.5 mm screwdriver.
If the clearance is too large, screw the valve
seat outwards (counterclockwise).NOTE that the
adjustment torque is very sensitive, so you should
screw carefully.The clearance can be checked
only when the secondary pressure is around 11.5
bar. (166 psi)
Fit the hose and open the LP valve. Check the
clearance once again.
Close the LP valve.
Adjustment of ejector sleeve:
Open the HP valve.
Turn the ejector sleeve using a 3.5 mm
screwdriver as shown in ill. B so that the edge of
the hole is opposite the slit in the low pressure
valve. See ill. C. Hold the second stage valve
upright, press the button so that the valve will
give a maximum flow of air, and then release the
button. If the valve continues to blow itself, stop
the air flow using your hand.Turn the ejector
sleeve in the direction of the arrow, see ill. B, and
make a new test using the button.The opening of
the hole should be turned to face upwards as
much as possible, that is, close to the limit where
the valve blows itself.The regulator will then give
a maximum flow of airand the inhalation
resistance is minimal.
Close the HP valve and purge fully with the purge
button. Tighten the nut moderately.
