Maintenance Tips

• Rinse After Every Dive: After every dive, thoroughly rinse the first stage in fresh water to remove salt, sand, and debris. Ensure that no water enters the regulator by attaching the dust cap when rinsing.
• Check for Leaks: Before and after every dive, check for any air leaks from the first stage. If you detect any, ensure the connections are tightened, and have it serviced if necessary.
• Clean and Dry: Use a soft cloth to clean the first stage after rinsing, ensuring all moisture is removed. Hang it upside down to dry fully before storing.
• Inspect the HP and LP Ports: Regularly inspect the high-pressure and low-pressure ports for any signs of damage, wear, or corrosion. Ensure the O-rings are in good condition and lubricated as needed.
• Annual Servicing: Have the first stage professionally serviced at least once a year to maintain optimal performance and safety. The technician will check internal components for wear and replace any necessary parts.
• Store Properly: Store the regulator in a cool, dry place away from direct sunlight or heat. Always ensure the dust cap is securely in place when not in use.
• Avoid Over-tightening: When connecting the regulator to the tank, avoid over-tightening the first stage to prevent damage to the valve or threads.
