Is too short. Make it longer.
I get it.. you use a coiled hose so that it's somewhat neat and organized when the user puts it away. The problem is that a lot of times, to reach the other side of your vehicle, the line gets overstretched. Especially if the machine is placed in an area where you can only logistically do head-in parking. Then it ends up breaking a lot faster. Then everyone gets to wait weeks to months for the machine to get fixed. Solution: make the air hose longer or have it attached to the machine at its base.
