Caution before use
!
・
Never operate the handpiece if it rattles after connection to the tubing
connector or if any abnormality is sensed. In such a case, consult the
Patterson Service Center.
・
Never attempt to forcibly connect the handpiece to the tubing
connector when the screw-in of the handpiece to the tubing connector is
too tight. Never use pliers or any other tools for the installation.
Caution
!
・
Never install a damaged attachment onto the handpiece such as a
worn-off bur, bur or prophy/contra angle with a bent spindle. Such
attachments may not only injure patients, but critically damage the
handpiece.
・
Never install a non-ISO standard bur or prophy/contra angle with a
non-ISO standard spindle.
・
Never open/close the chuck without installing the attachment onto the
handpiece, as the chuck holding power may be prematurely reduced.

２
. Changes in the rotating direction and rotating speed can be manipulated
with the control ring as shown below:
*When the ring is turned in "F" direction, the attachment installed onto
the handpiece rotates clockwise.
*When the ring is turned in "R" direction, the attachment installed onto
