The Patterson Hygiene Handpiece is intended for use by dental  

professionals only. 

Read this Operation Manual carefully before using the handpiece. Be 

sure to follow all the operating instructions, including all cautions and 

warnings.

Keep this Operation Manual for future reference. 

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.

Installation:

.  Make sure that the tubing connector is ISO standard 4-hole.

.  Align the air/water inlet ports at the handpiece back end with the

       corresponding holes of the tubing connector.

.  Holding the swivel ring of the handpiece with fingers, tighten the 

       nut of the tubing connector by turning it clockwise. 

 

Removal:

 

Holding the swivel ring, remove the handpiece from the 

    

tubing connector by turning the nut counterclockwise.

 

Removal of Bur Blank:

 

Holding the motor, twist the Bur Lock Ring 

    in the direction indicated by the black arrow until the chuck clicks open

    and pull the bur blank out.

 

Installation of Prophy/Contra Angle: 

. Make sure that the chuck is open.

. Insert the spindle into the chuck all the way until the back end of the 

prophy/contra angle contacts the shoulder of the nose of the handpiece, 

aligning the slit at the back end of the prophy/contra angle with the 

protuberance of the nose of the handpiece.

. Holding the motor, twist the nose in the direction indicated by the 

white arrow until the chuck clicks shut.

. Before operation, pull the attachment to make sure that it is securely  

installed onto the handpiece.  

 

Installation of Bur:

4. Operation

 Set the air pressure gauge for 2.0 kgf/

(28psi).

 Before operation, be sure to make a trial run and make sure: 

. The drive-air is not leaking from the connecting part of the handpiece 

back end and tubing connector.

. 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 

the handpiece rotates counterclockwise.

*The rotation is stopped at the center position between "F" and "R".   

 Select the rotating direction and the speed by manipulating the ring 

according to the treatment purposes.
