Your Carqon is equipped with a Dunlop Express valve, secured with union nuts and rim holes 8.5 mm/0.3"

To replace the valve and deflate the tire:

• Turn the upper knurled nut (1) in an anti-clockwise direction towards the top to let air out of the tires.
• Completely unscrew the lower knurled nut (2) in order to change the valve insert.
• Turn the lower knurled nut (3) clockwise as far as it goes in order to close the valve.

Depending on the type of valve, you need a pump to pump up the tires with a suitable valve connector or a suitable adapter. Contact your Carqon dealer for more information about the right pump.

Note: A good tire pressure improves your battery range, increases your driving comfort and significantly reduces the chance of a broken spoke.
