GG1E & LG1E MAINTENANCE

NOZZLE INSPECTION – RECOMMENDED EVERY 6-12 MONTHS

  1. Check for any apparent physical damage to components of Nozzle.
  2. Inspect Swivel Nut/Nose Piece seals for damage (ie cuts or excessive wear).
  3. Check that there is free rotation of Swivel Nut. Make sure the Pawl and Pawl Spring are functioning correctly. The Pawl should not be interfering with the ratchet lugs on the Swivel Nut when the Lever is inactive.
  4. Inspect the nozzle Inlet Swivel. The swivel should be secured by the grub screw through the nozzle body.
  5. Check the free movement of the Valve through the Slide Sleeve Assembly when not connected to an adaptor, (i.e., activate the Lever several times) making sure there is free movement forward and the Valve returns to its inactive position. Remove the Swivel Nut Assembly and clean and lubricate component if movement is not free.
  6. Inspect the Latch Assembly making sure that the bushes are firmly attached to the Latch Pin. The Latch Spring must hold the Latch above the Lever Latch Pin before latching.
  7. Fit a blanked adaptor firmly to the Swivel Nut. Activate the Lever and check for Valve opening (There is usually an audible “click” on the DN Nozzle). Whilst the Valve is open, check for Nose Seal and “U” Seal leakage using soapy water.
  8. Using soapy water check for leaks at inlet Swivel, Nozzle Body & Valve Assembly.

N.B. If there is Seal leakage or component damage, it is recommended that the Seals associated with the leakage and components, be replaced. Refer to L.G. Equipment’s Recommended Maintenance and Repair Manual for Repairs and testing of Nozzles.

TWENTY-FOUR MONTH INSPECTION.

L.G. Equipment recommends that a new Seal Kit be fitted throughout the Nozzle. Whilst this may seem extreme it will extend the life/service life of the Nozzle and reduce the occurrence of Nozzle downtime in service. Refer to the Gasguard Maintenance and Repair Manuals for the servicing of all Gasguard Nozzles.
