Avisualinspectionmustcheckthefullbreathingapparatusincludingallcomponentpartsandaccessories.Checkthattheequipment iscleanandundamaged,payingparticularattentiontopneumaticcomponents,hosesandconnectors.Typicalsignsofdamagethatmay affect the operation of the breathing apparatus include impact, abrasion, cutting,corrosion and discoloration. Report damage to service personnel and do not use theapparatusuntilfaultsarerectified.
3.5.2 Aircylinderfittingandremoving
!WARNING
High-pressureairreleasemaycauseinjurytotheuserorotherpersonnelnearthebreathingapparatus.Closethecylindervalveandfullyventthesystembeforeattemptingtodisconnectanaircylinder.
Impact damage to the cylinder valve or first-stage regulator connector mayprevent valve connection or cause an air leak. Handle the air cylinder andbreathingapparatuswithcare.
iiNOTICE
The following instructionsare foraCGA-type threadedcylindercoupling.Forothercylinderconnectortypes,refertotheInstructionsforUsesuppliedwiththeconnector.
Fitting the cylinder1. Checkthethreadsofthecylindervalveportandthefirst-stageregulator.Ensurethat
theO-ringseal(Fig4,Item1)intheregulatoriscleanandundamaged.2. Lay the apparatus horizontal, with the regulator uppermost, and fully extend the
