Cleaning and Drying the Exterior

Wash the handpiece under running water following the procedures 

below. (Water condition: ≤100°F, ≥3.5L/min; water should be of the 

same quality as drinking water)

- Clean the external surfaces of 

the handpiece with a soft 

bristled toothbrush for 15 

seconds or more. 

- Clean around the bur insertion 

hole for 15 seconds or more, 

using an interdental brush 

(wire thickness 0.7mm) that 

conforms to size 4 in ISO 

16409.

Under appropriate lighting 

(natural office lighting, 500 lx 

or higher), inspect the 

handpiece for blood or other 

debris. If any visible debris remains, repeat the process until the 

handpiece is visually clean.

After cleaning, if the residual moisture is present, wipe off with 

dry cloth or blow it off with compressed air (≤50.75psi) until there 

is no moisture in the interior and exterior.

When blowing off with compressed air, cover the handpiece with 

cloth to prevent scattering of water. Proceed to 6: Cleaning and 

Lubrication.

• The Patterson Brand attachment is intended for use by dental 

professionals only. 

• Read this operation manual carefully before using the attachment. 

• Be sure to follow all the operating instructions, including all 

cautions and warnings.

• Keep this Operation Manual for future reference.

• Consider primarily the safety of the patient and the operator when 

using the attachment.

Caution, before use

• Never use non-ISO standard, damaged or worn-out burs.

• Use clean burs. Dirt or debris stuck to the bur shank may clog 

the chuck mechanism.

Caution

• Do not use sprays other than PANA SPRAY Plus. Using sprays 

other than PANA SPRAY Plus may cause the handpiece to 

overheat.

• Hold the spray can upright.

• Firmly hold the handpiece to prevent it slipping when spray 

pressure is applied.

• Spray lubricant until it expels from the handpiece head.

• If you wish to purge excessive oil from inside the handpiece, 

rotate the handpiece for approx 15 seconds without a bur. 

During the rotation, do not depress the push button, especially 

when using absorbent cloth to prevent oil from scattering. 

Depressing the push button during rotation may damage the 

chuck mechanism. (NPB-Y)

Caution

• Never use the attachment if it cannot be smoothly installed 

onto or removed from the contra angle sheath. 

In such a case, 

consult the Patterson Service Center.

Caution

• Never use dry heat sterilization, cold sterilization, etc.

• Never autoclave the attachment with other instruments in the 

same sterilization pouch. 

• Never place the attachment at the bottom of the autoclave 

chamber, as the temperature at the bottom may rise above the 

actual setting temperature.

Caution

1. Specifications

- Perform installation/removal of head onto/from the contra angle 

sheath. Refer to instructions 8: Replacement of Head.

2. Installation/Removal of Head onto/from Contra Angle Sheath

NAC-Y and BB-Y

- Swing the latch plate out, holding the sheath connected to the head.

- Insert a bur into the chuck hole until the end of the bur touches the 

back of the chuck.

- Swing the latch plate back until it is snaps at the center of the 

collar of the contra angle head.

- Make sure that the bur is locked securely with the latch, pulling the 

bur with fingers and rotating it manually.

NPB-Y

- Holding the sheath connected to the head, press the head button 

with thumb to open the chuck and then insert a bur into the chuck 

hole. When the end of the CA bur touches the back of the chuck,

- Make sure that the bur is securely fixed after the installation, 

pulling the bur with your fingers and rotating it manually.

3. Installation/Removal of bur into/from Attachment 

NAC-Y

- Setting the motor speed below 30,000rpm, perform a test run of 

the attachment, making sure that the bur is securely installed.

- Use the attachment, setting the motor speed appropriately.

BB-Y and NPB-Y

- Setting the motor speed below 40,000rpm, perform a test run of
