– Charge assembly (P/N 15304). Includes a liquid-
filled gauge with snub valve, hose and fittings.
• NITROGEN bottle with a 800 psi/56 bar minimum
charge (not a part of 31254 kit).
1. Holding the chuck end of the STANLEY tester
(P/N 02835), turn the gauge fully counterclockwise
to ensure the stem inside the chuck is completely
retracted.
