Children No. 3 Ball No. 4 Elementary School No. 4 PVC Kindergarten No. 5 Football PU Adult Training Match Sports Equipment: Three Types of Footballs

1. Pump up the football Water or soapy water is usually used Before inserting the pump needle, wet it with water or soapy water. Dry air pump needles may damage the balloon valve and cause air leakage. Pump up little by little You need to pump slowly, gradually make the ball swell. If a compressor or similar device is used to force a large amount of air, the ball valve will clash with the stitching, causing the ball to break. Excessive pumping can cause the ball to deform or expand. Follow the air pressure regulations marked on the valve opening. 2. Check for air leakage Wash with soapy water Sand or dust entering the valve can easily lead to air leakage. Wash often and carefully with soapy water. And after cleaning, rinse well. Dry air pump needles may damage the balloon valve and cause air leakage. The new football has a leak When you pump for the first time, air will leak out of the pin. It's just the air that goes in between the bladder and the lining when you make the ball. This is completely normal and does not indicate a leak. 3. After the game training Clean the air after use It is precisely because the ball is often inflated before the game that it should also be deflated after the game. Always maintaining high air pressure when the ball is not in use will cause expansion and deformation. Scrub surface After use, the sand in the ball seam is swept away with a brush. Wipe the surface with a soft, damp cloth.
