23.2 Tilting high-volume suction
When you lift the suction handpiece from its holder, the weight of the suction
tube will cause the end of the handpiece to “tilt” slightly. This action opens
the handpiece valve allowing the suction to start.
You can stop the suction temporarily by “straightening” the suction
handpiece with your thumb and forefinger.
If you temporarily put the suction handpiece down during dental treatment,
the suction will automatically stop as the force of the suction will straighten
the handpiece.
