DANGER: Never use solvents or hydrocarbon-based products to clean or lubricate your regulator. Never use spray cans.

Servicing and inspections

Aqualung advises you to service your regulator every two years and to make a visual inspection at least once a year.
These two inspections should be carried out by a Aqualung approved workshop
Your regulator should be serviced more frequently depending on the number of dives and conditions of use.
