Eso sucede cuando la presión (el aire) sólo que da en la manguera y no está entrando al shox o horquilla. Solución verificar que al roscar la perilla roja realmente libere la válvula del shox para que pueda ingresar y leer la presión. Saludos!
I tried pumping the shock many times, I found the stem that pushes valve isn't long enough so the air is trapped between the chuck and the valve. Also a O-ring in the chuck didn't last long and air started leaking. I ended up buying a Giant shock pump that looks really similar to this one but it works! Sometimes spending little bit extra money saves your time and hassle. Bit disappointed about this product though especially it's from Taiwan.
@@trailninja7346 Pressure is rising _very_ fast when you are pumping, so I think @jgat007 was right on this one. You were just pumping the line and not the shock. User error :)
