This is a KAVO ELECTROtorque plus motor unit, power supply, KL701 connector, and mount. Everything in the picture is what you get. It works great, but I don't use my electrics very often. I'm switching my operatories around so I decided to let someone else benefit from them.
The unit has a fiber-optic light if your hand pieces are compatible to work with it. If you don't have a suitable hand piece, keep reading. I really like the fiber-optic light. It's also nice that you can use these and a high speed or slow speed depending on where you set the RPM. Please read up on them online to get specifics. I don't have the manual, but I'm sure you can find it online. All will be listed separately. I have videos of all the hand pieces and motors operating. I bought a practice with these in it when I got there. Apparently they were installed a few years before I bought it and rarely used. I hardly used them in my time in the practice, but I did use them a few times without any issues. They were a nice backup when my air turbine hand pieces acted up and they cut like crazy due to all the torque!I have never had them serviced or tested. All I know is that they make tooth dust when you hit the pedal. You can see there is a little scuffing of the tubing due to where they rubbed the ground, but there are no holes.
Zoom way in on those photos and check it out. If you happen to be in Denver, I'd be happy to demonstrate their good working order in my office for you. It's easy to hook them back up for a demo.
