Handpiece Attachment/Detachment
To Attach: Hold the handpiece cord connector at the rear of the main control unit, facing the triangle indicator at the
12 O’ Clock position (see diagram N). Plug in to the handpiece cord port when proper alignment is reached.
To Detach: Squeeze the serrated section on the handpiece cord connector (by the triangle) and gently pull back (see
diagram O). Connector does not turn.

GUTTA PERCHA
SYSTEM
Theory of Operation
The heating system of the Obtura III MAX is a closed-loop design to ensure consistent temperatures and uniform gutta
percha flow. This means that the temperature of the heater is read several hundred times per second and corrected (as
necessary) to insure accurate and consistent heating.
In the handpiece, the temperature of the heating chamber is detected by a thermocouple integrated into the heating
element and encapsulated with epoxy. The output from the thermocouple is converted by an analogue-to-digital
converter, and into a digital stream for use by the main control unit.
The handpiece is composed of a two-piece heat-resistant composite body that encapsulates the trigger assembly, heater
system and plunger.
Gutta percha is placed into the top of the handpiece shell and expressed via the plunger shaft assembly. Pressing the
handpiece trigger, which pushes the shaft via a spring-loaded pawl, moves the shaft forward. The heater assembly is
directly connected to the handpiece shell, providing a straight through path for gutta percha, warming it in the process.

Maintenance
For best results, the Obtura III MAX handpiece should be cleaned daily. This prevents build-up of excess gutta percha
within the heating chamber.
Regular Maintenance (Day to Day Cleaning)*
Tools you will need:
•
Multi-Tool
•
Cleanin
g brush and Cleaning solution
•
Disposab
le cloth (na pkin, gauze, etc.)
1. Prior to cleaning, ensure that your Obtura III MAX unit is turned off, fully cooled and unplugged.
2. Unlatch and remove the thermal protector using the Multi-Tool.
3. A) Use the Multi-Tool to unscrew the needle nut from the heater thread.
B) Set aside the needle nut. Dispose of the needle (for optimum performance, Obtura applicator needles
------
should be used only once).
4. Extrude all remaining gutta percha by squeezing the handpiece trigger. The gutta percha will come out in solid pellet form.
5. Push and hold the release button, removing the plunger shaft from the handpiece.
6. A) Inspect the plunger seal for gutta percha.
B) If gutta percha is present, dip the cleaning brush into the cleaning solution, fully coating the brush.
C) Clean the plunger seal with the cleaning brush in a back and forth motion until all visible gutta percha is cleared.
7. A) Inspect the inside of the handpiece shaft for any visible gutta percha.
B) If gutta percha is present, re-dip the cleaning brush into the cleaning solution, fully coating the brush.
C) Place the cleaning brush inside the handpiece shaft and clean in a back and forth motion until all visible
------
gutta percha is cleared.
8. A) Reassemble all components in the reverse order from which they were detached.
B) Place the handpiece back on its cradle.
WARNING: AT NO POINT SHOULD ANY PART OF THE OBTURA III MAX HANDPIECE BE SUBMERGED
INTO THE CLEANING SOLUTION.
NOTE:
A) For optimal cleaning, use a Birex®-type solution to aid in disinfecting and deodorizing your Obtura III MAX unit.
B) Never spray the disinfectant solution directly on to the unit; always spray into a disposable cloth, then wipe down.
*The above regular maintenance cleaning instructions are also displayed on the provided laminated cleaning
instruction card, which contains visual diagrams for your convenience.
