Inflatable lifejacket with Interlock lung
Why is maintenance of inflatable lifejackets important?
Inflatable lifejackets require technical inspection and annual maintenance to ensure that the lifejackets work as required when you need
them. You can carry out pre-use inspections yourself. Read the user manual carefully! Check that the vest is intact before use. Open the
cover and check the lung itself. Make sure that the CO2-cylinder is fully screwed into place and is not damaged. Check that the end cap is
screwed fully into place and that the indicator clip is correctly in position. Ensure that the pull cord is placed outside the outer cover.
