Note: Do not overfill1. Inflation method:1) Spread out the air cushion, open the air nozzle, and the air cushion bed will automatically start to expand.2) Please wait until the air cushion bed has expanded and then tighten the air nozzle cover.3) Adjust the air pressure and adjust its comfortable hardness.Attention: If stored in a coiled state for a long time (not recommended), please blow air several times with your mouth to expand and restore elasticity.2. Method of exhaust:1) Open the air nozzle, roll it up from the other end of the nozzle, and press out the air.2) Close the air nozzle, roll up the air cushion bed from the other end, and open the air nozzle again to expel any remaining air.3) Finally, close the valve and save it in a rolled state at any time.Attention: Please place it in an outer bag when carrying it to avoid scratches.3. Repair method:1) Confirm the location of air leakage: After blowing and expanding, close the valve, wet the surface with water or dilute soapy water, fold it in half, and press it with your knees to pressurize your weight. The bubbling area is also the location of air leakage, please mark it.2) Small hole repair: Completely dry the air cushion bed, release air, and apply adhesive to the hole. Because the air has been exhausted, the adhesive will be sucked in, sealing the hole. Afterwards, wait for the adhesive to harden.3) Major damage repair: Completely dry and deflate the air cushion bed, apply glue to the repair cloth, and also apply glue to the holes on the surface of the air cushion bed. Let it dry for 30 seconds to 3 minutes (depending on the temperature), stick it to the damaged area, press it flat, and keep it for 4 hours before use.4. Precautions:1) Do not approach sharp objects (plants with thorns or sharp stones or blades).2) When not using a tent, please lay a cloth underneath the air cushion bed.3) Do not use it as a float.4) Stay away from flames or sparks.5) When the temperature is high, do not place an inflated and closed valve air cushion bed in a car or tent.6) Do not touch sunscreen or alkaline drugs.7) Do not expose to sunlight for a long time, as ultraviolet radiation can slowly damage the surface material.8) Please keep it out of reach of pets.9) The air nozzle is relatively hard and should be avoided during rest.
