Maintenance Tips Rinse the first and second stages with fresh water after each dive. Keep the first stage dry (avoid submersion) and gently rinse the second stage without depressing the purge to avoid water entering internal hoses. Dry Thoroughly Shake off excess water and hang the regulator in a cool, shaded, dry area until fully dry before storing or transporting. Never store while wet to prevent corrosion and moisture buildup. Inspect & Check Leaks Before use, check hoses, O‑rings and connections for wear, cracks or kinks. After rinsing, attach to a tank and listen for air leaks around both stages; replace worn seals promptly. Lubricate O‑Rings Apply silicone‑based lubricant sparingly to O‑rings and hose fittings; avoid petroleum‑based products that can degrade rubber. Protect & Store Properly Store the regulator in a protective case away from direct sunlight, extreme heat or humidity. Keep it disconnected from tanks and hoses un‑kinked. Annual Professional Service Have the regulator serviced annually (or every 100‑200 dive hours) by an authorized Zeagle technician to clean, inspect, replace seals and ensure optimal performance — critical for safety and warranty compliance.
