Ball maintenance

Football


Before each inflation
Always drip 1-2 drops of hummel valve oil into the valve before inflation to ensure that it seals properly.

Storage
Store the ball at reduced pressure in a dry, airy place at 20-25˚C.

Cleaning and drying
After use clean the football in mild soapy water and rinse with water. Then wipe the ball off with a towel and let it fully dry in a dry,  airy place at 20-25˚C.
Never dry the ball on or near a heating device.

 

Football inflation guide 

1. Preparation
During wintertime we suggest to store the footballs at room temperature (20-25 ̊C) for minimum 24 hours before the first inflation in order to secure optimal softness, shape and grip.

2. Valve oil
Drip 1-2 drops of hummel valve oil into the valve. It is important that valve-oil is used at every inflation as it makes the valve seal properly.

3. Inflate
Position the valve upwards and insert the inflation needle straight into the valve. Always use a long pump needle to ensure the needle does not damage the valve or the bladder.

4. Check pressure
- Inflate the ball to the recommended pressure.
- Recommended pressure is printed on the ball near the valve.
- Inflate slowly to allow the ball to gain its correct shape – rapid inflation can damage the bladder.
- Use a pressure gauge to check the pressure of the ball.

 

What to do if your ball rapidly loses air/pressure

If your ball loses most pressure within 1-2 days it is possibly due to dirt in the valve or the valve being dry which can stop it from sealing properly.
This can usually be cured by clearing the valve as follows; Drip 1-2 drops of valve oil into the valve. Insert the inflating needle into the valve and rotate the needle by rotating the end of it in a small circle, also moving the needle gently up and down. The dirt obstructing the valve will be cleared by the valve oil and the valve should seal.

Resin removal by machine

In case you use machine for removal of resin, please take caution on these things to minimize the risk of damaging the ball
-  Make sure the machine is heated properly before use (so the brushes are soft)
- Make sure the brushes are cleaned frequently (so they don’t get too short and stiff)
If these steps are not followed the brushes can damage the surface material of the ball.
