Chapter Four is an operational description of the Kreativ Multi-Operatory
accessory.

Chapter Five provides preventive maintenance and troubleshooting procedures.
Also included is a replacement part and accessory list for re-ordering your
supplies.

Chapter Six is the warranty policy for the Kreativ Multi-Operatory accessory.

General Information and Features

The Kreativ Multi-Operatory Accessory offers the capability of extending the
use of a Mach 5/5+ Air Abrasion system into two dental operatories without the
additional cost of a second air abrasion system, or the requirement of moving
the air abrasion unit between the two operatories. The air abrasion system can
be located up to 16 feet from either operatory.

The Multi-Operatory Accessory uses the same air controlling technology as the
Mach 5/5+ to reliably route abrasive/air to either of the selected operatories. The
unit automatically senses when a handpiece is removed from its cradle, and
activates the related footswitch. The other operatory is locked out from use or
input whenever the handpiece from the operatory in use is uncradled.

Other features of the Kreativ Multi-Operatory Accessory include:

Second Remote and footswitch is provided for the second operatory

•

Automatic blanking of idle remote display

•

Convenient access to pinch tubes for periodic maintenance

•

Direct mounting to front of Mach 5/5+ system

•

Optional rear-mounting capability

•

Ability to bypass remote when handpiece is removed for sterilization

•

Optional dental chair integration kit to eliminate multiple footswitches
