All Molten balls are designed to withstand rough treatment. Should damage occur, however, it is important to act quickly before it gets more serious. If you care for your Molten ball, it will repay you with many years of superior performance. Checking for air leakage (1) Inflate the ball. (2) Put the ball in a bucket filled with water. (3) Gently immerse the ball in the water while looking for any bubble streams. Note carefully where they are. [Understanding the symptoms] If the bubbles emanate from the centre of the valve: A. Defective valve If the bubbles emanate from the surface of the ball: B. Small punctures (less than drawing pin-sized) Repairing the damage A. Defective valve (1) Push the end of the valve changer (VA) all the way into the valve. (2) Twist the valve changer slightly and pull it slowly towards you. (3) Pull the valve all the way out. (4) Soak a compatible new valve in soapy water or detergent. Use the valve inserter (VB or VB2) to insert the valve into the opening in the ball. (5) Screw the new valve into place tightly, while holding the head of the valve inserter with a cloth or towel. (6) Inflate the ball. (7) Leave the ball for 24 hours, and then recheck for leaks. (8) The ball is now repaired. B. Small punctures (less than drawing pin-sized) (1) Inflate the ball until it is 70-80% full. (2) Prepare a can of ball repair sealant RL420, and shake it well. (3) Wet the can's insertion needle with water, and then push it all the way into the valve. (4) Spray repair sealant into the ball for 5-6 seconds. (5) Inflate the ball fully. (6) Bounce the ball 10 times, and then leave it for an hour with the hole to the ground to let the sealant sink. Check for other leaks. (7) The ball is now repaired. Air leakage caused by worn-out valves is easily fixed by replacing the valve. Remove the old valve with the key-shaped valve changer, while taking care not to damage the valve. Soak the new valve in soapy water or glycerin, and then use the valve inserter to push it all the way into the opening. * Once the new valve is in place, use the air insertion needle to make sure it is fully inserted.
