Although service and repair of the Cavitron JET Plus
Combination System should be performed by DENTSPLY
personnel, the following are some basic troubleshooting
procedures that will help avoid unnecessary service calls.
Generally, check all lines and connections to and from
the System. A loose plug or connection will often create
problems. Check the settings on the System's controls.

each to ensure that the proper Foot Control is being
used. With a handpiece and insert installed, depress

sufficient. Make sure valves are open when using
