4.6.5 Re-Assembling the Air Shield Valve
Referring to DIAG 11 and 12 (below):
Locate the Diaphragm (Large) (A). Insert into the Valve Cavity in the Pistol.
Place the Diaphragm Disc (C), plunger first into the Valve Retainer (B) and then into the Valve
Cavity, disc side first.
Check that the disc is free to slide, and fit an ‘O’ Ring (E) into the groove formed between the
retainer and the cavity wall.
Place the Diaphragm (Small) (D) in the retainer recess.
Follow with the Valve Cap (F), placed in with the single hole facing outwards. Also ensure that
the single threaded hole at the edge of the cap is positioned correctly to accept the Valve
Screw (G) and insert the screw through the body wall. DIAG 12 (below, right) demonstrates
the positions of these parts.
Fit the ‘O’ Ring (H) into the groove between the body and the Valve Retainer.
