Hoses should be inspected for kinks, flat spots, abraded outer cover (wire <br /> strands visible)and leaking fAtings on a weekly basis- <br /> Note: The folio 'ng procedures shall be conducted after installation or repair, <br /> with the dispenser authorized and ready to dispense fuel. <br /> 1.1 Field Serviceable Hose Components <br /> 1.1.1 Healy Part No. HB-2 0-ring(item 1, in Figure below). This o-ring seals the fitting <br /> to the nozzle and the adapter. Uquid gasoline visible on the hose indicates a <br /> damaged or improperly installed HB-2 o-ring. Replace the o-ring, if necessary. <br /> 1.1.2 Healy Part No. HB-4 Quad Seals(Rem 2.in Figure below). These quad seals <br /> are used on the end of the hose that attaches to the breakaway assembly(or <br /> flow limiter, if equipped). If the symptom is meter creep(gallons dispensed <br /> display on dispenser is counting up when the nozzle is not dispensing gasoline), <br /> check the HB-4 quad seals at the breakaway(or ftw limiter, if equipped)end of <br /> the hose for cuts or damage. Replace the seals, if necessary. <br /> 1.1.3 Healy Part No. 291 O-ring (item 3, in Figure below). These o-ring seals are used <br /> on the end of the hose that attaches to the nozzle or hose adaptor assembly. If <br /> the symptom is meter creep(gallons dispensed display on dispenser is counting <br /> up when the nozzle is not dispensing gasoline), check the 291 0-rings at the <br /> nozzle or adaptor end of the hose for cuts or damage. Replace the seals, if <br /> necessary. <br /> Lubricate any o-ring or Quad Seal before installing the hose assembly into an adaptor, <br /> breakaway or nozzle assembly to make it easier to install and prevent the seal from <br /> getting cut. Motor oil(any weight) is acceptable for lubricating an o-ring or Quad Seal. <br /> Rule of Thumb.- ®-rings to Nozzle and Hose Adaptor <br /> Quad Seals to Breakaway(or Flow Limiter) <br /> Healy Systems, Inc.
