Warnings and Cautions
• Do not run the handpiece in reverse; the cup or brush will come off.
• Operate the handpiece outside the oral cavity before actually using it to make sure it does not
overheat and the cup or brush does not wobble. Also make sure it runs at the right speed in the
right direction and does not operate abnormally in any way.
• If a cup or brush comes out during use, stop using the handpiece immediately and have the
handpiece repaired.
• Never use the handpiece with no or too little cooling air; this could cause it to heat up and possibly
burn the doctor's hand or the patient's mouth.
• Wait for the cup or brush to stop moving before taking the handpiece out of or putting into the oral
cavity.
• To avoid cutting your fi nger etc., wait until the handpiece has completely stopped rotating before
inserting or removing a cup or brush.
• Do not use any cups or brushes different from specifi ed screw length. Otherwise the cup or brush
could come out.
• Wear safety glasses to prevent injury to your eyes.
• Never switch rotation direction from forward to reverse or vice versa while the motor is actually run-
ning.
• Remove the cup or brush before returning the handpiece to its holder in the dental treatment unit;
otherwise, there is a risk of injury or damage.
• If the handpiece makes abnormal noise or vibration, take out the cup or brush and replace it with a
new one. If the same problem persists, have the handpiece repaired.
• Follow all recommendations of the cup or brush manufacturer concerning rotation speed and direc-
tion.
