Attaching Handpieces
Once the correct handpiece configuration has been determined, the handpieces can be attached. Ensure that
the handpiece you will be using has a gasket at the end, and that it is in good condition to prevent potential
air/water leaks.
The handpiece connection has very fine threads and a gasket on the back end that
must screw onto the tubing tightly in order to seal correctly. For new handpieces
it is recommended to screw on the handpiece tubing, then loosen and clean
threads and then screw on again to ensure a tight seal fit on the gasket to prevent
air and water leaks.
Five Hole Connection
Attaching Non-swivel Handpieces
Place the handpiece onto the coupler and ensure that the tubes from the handpiece align in the connector, and
that the gasket on the back of the handpiece is seated against the connector. Then firmly tighten the metal nut
onto the handpiece. To get a good seal, it may be necessary to slightly unscrew the metal nut and then retighten
to secure.
Attach Swivel Coupler onto Handpiece Connector
For handpieces that have a swivel coupler at the base, use the following instructions. The manufacturer’s
handpiece/coupler wrench is required.
1
Remove the quick connect coupler from the handpiece; see first figure below.
2
Insert coupler into handpiece connector, carefully align the coupler to handpiece connector, making
sure the rubber gasket touches; see second figure below.
3
Firmly tighten the coupler into handpiece nut. Use the manufacturer’s small flat wrench to hold coupler
while tightening, if necessary.
4
Place handpiece onto the quick connect coupler; see third figure below.
