EMS Hu-Friedy AIR-FLOW Notice D'utilisation page 26

The air/powder jet is powerful. It can cause injury to the gums or an emphysema caused by the
introduction of air into the soft tissues. It is strongly advised to never direct the nozzle at the gum tissue
or into the gingival sulcus.
Proceed with small circular motions for the treatment. Polish all dental surfaces after the treatment
by setting the water flow rate to maximum.
