8-6 Operation
Powder, water, and air are supplied when the Foot Control button D is depressed. Water and air are supplied when the Foot Control button B
is depressed. Observe the operating instructions explained in "8-6-1 Using Prophy Mode" and "8-6-2 Using Perio Mode."
• Never spray powder toward a human body including the operator and the assistant other than to the tooth surface.
• Stop use immediately if the hose swells or air or powder leaks from connections between the Chamber and Hose during use.
WARNING
• Spray water while using this product.
• Be sure to use a vacuum tube (and a saliva discharge tube together if necessary) to prevent the patient from ingesting a large
amount of powder. Avoid continuous use over long periods and allow the patient to rinse out the mouth whenever necessary.
• As a safety feature, this product will not switch on when the Power Switch is turned to ON while the Foot Control is depressed.
An alarm sound is heard and the tooth icon and "POWDER" flash alternately. Release the Foot Control then depress it again.
CAUTION
• Before treatment, adjust the Power Level and the Irrigation Level before using on the patient.
• Reduce the Power Level when treating around marginal gingiva.
• Do not spray vertically onto the tooth surface.
• Maintain the distance between the tip of the Nozzle of the Handpiece to the tooth surface as explained in "8-6-1 Using Prophy
Mode" and "8-6-2 Using Perio Mode."
• Do not rotate the Handpiece Holder forcibly as it may damage the Holder.
NOTICE • A buzzing sound may be emitted, but this does not indicate a malfunction.
8-6-1 Using Prophy Mode
Keep the Nozzle at a distance of 3 - 5mm from the tooth surface and at an angle
of 10 - 60 degrees (Fig. 32).
• Never point toward soft tissue, gum, or the subgingival area.
WARNING
• Spray from the root to the incisal edge of the tooth.
CAUTION
8-6-2 Using Perio Mode
Using with the Nozzle Tip
Insert the Nozzle Tip deeper than 3mm into the periodontal pocket (Fig. 33).
Powder may not be sprayed efficiently into the periodontal pocket if the depth is
less than 3mm.
Using without the Nozzle Tip
Remove the Nozzle Tip from the Nozzle of the Handpiece to remove plaque at the
supragingival area and gingival margin, or to remove biofilm and light stains. Keep
the Nozzle at a distance of 5 - 10mm from the tooth surface and at an angle of 30
- 60 degrees (Fig. 34). Never point the Nozzle directly toward the oral mucous
membrane or in periodontal pockets.
