Why do I need to equalize the pressure when airing up my shock?

When initially airing up your shock, you will need to equalize the positive & negative chambers. The air from the pump will flow into the positive chamber and you will need to compress the shock in order for the air to transfer to the negative chamber. This video will teach you the proper way to do this.

What do the positive and negative chambers do?

The negative chamber is responsible for counteracting the forces of the positive air pressure. This is your beginning stroke. The Positive pressure is your air spring. This controls your mid-stroke and bottom out. In the Topaz, the two chambers work together to create a seamless transition throughout the stroke.
