Warnings

WARNING: This product is intended for use by dental
professionals only. Before operating handpiece, carefully
read and follow these instructions and save them for future
reference. Observe all cautions and warnings, including:
• Handpieces should be heat-sterilized between patients to
prevent cross-contamination which could result in serious
illness or even death from infectious organisms such as HIV
(the virus that causes AIDS) or hepatitis B.
• It is the responsibility of the Dental Healthcare Professional
to determine the appropriate use of this product and to
understand the health of each patient, the dental procedures
being undertaken, industry and governmental agency
regulations, and recommendations and requirements for safe
practice of dentistry.
Precautions
• Do not operate handpiece unless prophy angle or cup is
properly secured. A loose prophy angle could eject from the
handpiece and cause personal injury.
• Do not use angle, attachment or accessory that exhausts air
within the oral cavity when a soft tissue wound is present. Air
pressure may force septic materials into these tissues.
• Before using, allow handpiece to cool completely after
sterilization.
Adverse Reactions
None Known.

Note: Never operate air motor under the following conditions:
1. At air pressure exceeding 45 p.s.i. (3.1 Atm.).
2. On an alternate hose without adjusting air pressure.

for routine maintenance, the oiler should be disconnected.
Do not use oil mist lubrication. (Excess oil may hinder
performance.)

speeds up to 6000 RPM.

air at the recommended operating pressure of 30-40 p.s.i.
