How to use the Maddle manual pump?

1.  Make sure the pump’s air intake valve located under the handle is closed. This will allow the pump to inflate during both up and down motion.
2. Connect the hose to the OUT connector located underneath the handle. Use the pump for a few strokes to see if the pump seems to blow air. If it seems to suck air in, the hose is connected to the IN side, and you need switch the hose to the other side of the handle (OUT).
3. Connect the pump’s hose to the air valve by pressing down and twisting the hose in a clockwise direction.
4. Begin inflating the board using the handle in an up/down motion. It will be quite a workout to inflate your board, it is normal to feel a bit of muscle pain or fatigue by the time the board is fully inflated. 
5. **Please note that even though the board will appear rock solid visually, the pump will not show a reading until you reach about 7 PSI**
   a. The pump is not defective, you just have to keep going until the board is filled up to that level. Afterwards, you will be able to get a reading on the gauge.
6. Midway through inflation, or when you find yourself having difficulty inflating the board, twist open the air intake valve located at the top of the pump’s air chamber to turn it from double action (pushes air on the way up or down) to single action (pushes air on the way down only. This is usually recommended after 9 to 10 PSI.
   
7. Keep pumping until your board reaches the recommended pressure level reading of 15 PSI.
8. While we use high quality valves that are rated to go up to 20 PSI, we recommend inflating your Maddle from 15 to 18 PSI.
   Most users will not see any differences between 15 PSI and 18 PSI, and 15 PSI will give you a very rigid feeling, without coming with additional pump time!
9. Once the board is inflated to 15 PSI, remove the pump’s hose from the air valve by twisting the hose’s tip counterclockwise.
10. Close the air valve cap by turning it clockwise.

Do not touch the piston in the center of the valve, otherwise you risk deflating your board after all of your hard work!
