OVERVIEW
Congratulations on your purchase of the Obtura III Max! Please read the entire manual prior to using this unit. Here are some useful tips that
will aid your usage of the Obtura III Max:
When you are ready to practice with your Obtura III MAX, you should become familiar with its components. After attaching the needle and thermal
protector, turn the Obtura III MAX ON and set it to operating temperature. It takes the unit approximately 180 seconds to reach the highest operating
temperature of 200°C. The high temperature setting will improve gutta percha ow, especially when used in the cold practice block (sold separately).
Begin by lling the plastic practice blocks with gutta percha per the instructions included. Use condensers to condense the material void free.
We recommend the Obtura Spartan S-Kondenser (available in 3 sizes).
• The soft silver applicator needles are designed to conduct heat to ensure even heat at the needle tip; however, as the needle tip cools
between uses, you should express 3 cm of gutta percha to pre-heat the tip just prior to use. The needles are bendable to t the tooth,
however, they may break if they are bent more than once or outside the parameters in this manual. Always use the Multi-Tool to bend the
needle to avoiding kinking the needle, as any restriction will impede ow. After a few practice sessions, proper needle bending will be easily
accomplished. Obtura Applicator Needles are for single use only.
• Do not loosen or remove the blue plastic Heater Nut. The Heater Nut is fastened to the gun with a set-screw; removal of the heater nut will cause
damage. The Heater Nut must be kept tightly fastened in order to secure the heater to the handpiece when expressing gutta percha.
• The stand for the handpiece may be positioned by itself or it may be attached to the bottom of the control unit. The stand can be attached to
either side of the control unit with four phillips-head screws that are fastened to the bottom of the stand (see page 5 for further details).
• The cord to the handpiece can extend from the front or rear of the unit. If a front exit is desired, gently press the handpiece cable into the tracks
on the bottom of the unit, to exit either on the left-front or the right-front (see page 5).
• Cleaning the Obtura III MAX is simple but very important; just follow the directions in this manual (see page 7) or on the provided laminated
cleaning instruction card. If you do not clean your unit, it may become clogged and difficult to move the plunger due to a buildup of old, hardened
gutta percha.
Thank you for purchasing the Obtura III MAX. We believe it is a benecial instrument that will enhance your practice. We are continually striving to
improve our products and services. If you have any questions or suggestions, we would appreciate hearing from you. We are also interested in seeing
any X-rays you may have of interesting cases. Feel free to contact us at: 800-558-6684 (or 1-877-485-3556 in Canada); we welcome the opportunity
to speak with you. Also, visit our website at: www.youngspecialties.com.

SYSTEM DESCRIPTION
The Obtura III MAX is intended for use by professionally-qualied dentists, endodontists and dental clinicians to heat gutta percha and to place it into
the previously prepared root canals of human teeth, in order to provide quick and complete obturation of the root canal.
There is a minimum level of understanding and background assumed in the descriptions and instructions found in this manual; if at any time you
feel overwhelmed or unsure of how to properly operate your Obtura III MAX unit, immediately cease use and call Obtura Spartan for assistance.
We value safety rst and foremost.
The Obtura III MAX features an interchangeable plug-in handpiece. Any Obtura III MAX handpiece will work with any Obtura III MAX base unit.
However, the Obtura III MAX handpiece cannot be retrot to the Obtura III or any other previous model.
The Obtura III MAX utilizes push-button digital temperature controls for more accurate, reproducible settings, and a memory function that stores
up to 5 user-selectable temperature settings for your convenience.
The Obtura III MAX complies with current Electromagnetic Compatibility standards (IEC 60601-1-2). The user should ensure that any possible
electromagnetic interference is not present, as it could potentially damage the device or any other electronic device in the vicinity.
UNPACKING AND ASSEMBLING
Check all packaging for signs of damage; report any damage with the shipping agent immediately, so that claims will be honored in a timely way.
Save all packing materials in the event of an instrument move or shipping at a later date.
Remove the clear plastic documentation, main control unit, handpiece, handpiece stand (complete with stand attachment spacer and screws), power
supply box, bagged supplies and accessory tool kit. Check for loose items.
Unwrap the main control unit and place on a at surface. Locate the unit so that by extending the cord you will not pull the unit OFF the surface.
The hand piece cable length is approximately 2m.
Locate the handpiece stand and place it next to the main control unit. The stand provided for the handpiece can be attached to the Obtura III MAX (if
desired) by the following means:
After determining which side you want the stand placed on, simply remove the 2 screws on the bottom of the stand. After the screws are removed
hold the attachment plate to the bottom of the stand, and re-attach it to the desired location so it hangs off the side (as shown in diagram A). Then
attach the handpiece stand and bracket to the main control unit using the two remaining screws (see diagram B).
Plug the handpiece cord connector into the rear of the main control unit. Note: the alignment of the “triangle” at the 12 o’clock position, and a
“click” to signify complete insertion. Should the user require the cord to exit the front of the unit, invert the Obtura III MAX on a smooth, soft surface
and gently press the cable into the tracks provided, leaving a small loop of cable from the handpiece cord port to the beginning of the track. Failure to
do so may cause premature wear on the handpiece cord and/or the connector. The cable can exit on the left-front or the right-front (see diagram C), or
from the rear (without use of the cable tracks).
Open the white power supply box and remove the power supply unit and receptacle blades. Reference power supply manual for complete use and
safety information. Choose the correct blade to t your electrical outlet and slide it on to the power supply unit. Plug the power supply connector
into the power supply port at the rear of the main control unit; plug the power supply unit into an electrical outlet. The Obtura III MAX screen will
momentarily light up, indicating the version of installed rmware, and then turn OFF. This only occurs when rst connecting the main control unit to the
electrical outlet.

OPERATION
Operation of the Obtura III MAX has been designed to be intuitive, however, to fully realize the extent of the instrument and its many features,
please read this entire section.
There are four (4) tactile switches on the front of the Obtura III MAX and an LCD display. The functions of the four switches are: Power ON/OFF,
Temperature Up, Temperature Down and Temperature Memory (as shown in the “Quick Start Guide” section). When the Obtura Ill MAX is activated,
the 3-digit display will indicate the current operating temperature in degrees centigrade, and any memory presets desired. Description of each button
follows:
• Press the Power ON/OFF button to activate the Obtura III MAX. The display will show the last used set-point temperature. After 5-seconds,

OPERATOR’S MANUAL HEATED GUTTA PERCHA SYSTEM
Page 6
the actual heater temperature will be displayed, heating up to the set-point. Press the Power button again to toggle OFF.
• With the unit ON, press the Temperature Up(+) button to increase the set-point temperature in single degree increments.
Press the Temperature Down(-) button to reduce the set-point temperature, also in one degree increments.
• The Temperature Memory button retrieves preset memory set-points. A quick press of this button displays the letter “M” and the preset position
number. The temperature associated with the memory setting is displayed on the three-digit display. To set the unit to this temperature, no other
action is required, and after 5 seconds, it will now be the new set-point temperature and will be indicated on the unit screen. To access another
memory position, again press the Temperature Memory button to display the desired memory setting, and again within 5-seconds, the unit will
set to the next positioned temperature.
• To reset a memory location, press the Temperature Memory button until the preset position number you want to modify is shown. Then, within
5 seconds, adjust the preset temperature with the Temperature Up(+) and Temperature Down(-) buttons. The memory and the display are
now set to the new temperature. After 5 more seconds, with no button pressed, the Obtura III MAX display will change from the previously set
temperature to the new set-point temperature. Note: preset memories are saved even during power failure.
The Obtura III MAX requires approximately 180 seconds to heat from ambient room temperature of about 25°C, to maximum operating temperature of
200°C.
For your convenience, the table below can be used as a reference:
Memory Number Factory Preset New Setting Date
M1 140°C
M2 150°C
M3 170°C
M4 180°C
M5 200°C
INSTALLING A NEEDLE
To place the gutta percha where desired in the root canal, choose an applicator needle diameter best suited (20, 23 or 25-gauge) to the application. With
the Obtura Ill MAX off and cool, remove the needle nut using the Multi-Tool; the needle nut should remain on the Multi-Tool when unscrewed. Place the
appropriate needle in the rear of the needle nut so that the length of the needle protrudes through and forward (diagram G). Re-attach the needle nut on
to the heater thread using the Multi-Tool, making sure not to cross-thread (diagram H). Tighten until snug (do not over tighten, but do not leave too loose).
Always take care when handling the needles to avoid injury. Install the thermal protector over the needle nut and blue plastic Heater Nut. The thermal
protector tab ts in the opening just behind the silver serial number ring.
G H
BENDING THE NEEDLE
In most situations, a straight applicator needle will not provide access to the root canal. Using the Multi-Tool, gently bend the needle to provide
a shape conducive to the procedure (see diagram I) Only bend once at the largest diameter as close to the thermal protector as possible. Never bend
more than once or at a taper location; bending outside of these areas may result in breakage. Always use the Multi-Tool to bend the needle. Failure
to do so may cause kinks which will result and gutta percha ow will be blocked. For access to difficult to reach root canals, simply loosen the needle
nut, rotate the needle to desired position, and then re-tighten.

LOADING GUTTA PERCHA
WARNING: USING MORE THAN ONE STICK OF GUTTA PERCHA AT A TIME MAY DAMAGE THE SEAL. DO NOT USE MORE THAN ONE
PIECE AT A TIME. NEVER LEAVE A PARTIAL STICK IN THE CHAMBER BETWEEN PROCEDURES.
Press the handpiece release button on the top of the Obtura Ill MAX handpiece and withdraw the plunger shaft Power ON the Obtura Ill MAX and wait
for the heater to come up to your desired temperature. Insert a gutta percha stick into the chamber via the opening just forward of the release button
(see diagram J). Re-insert the plunger shaft until the plunger seal engages the gutta percha pellet. Some resistance will be felt as the gutta percha is
pushed forward to the heating chamber.
J
EXPRESSING GUTTA PERCHA
Specics to technique will not be addressed here, but a few reminders and hints follow:
• When expressing gutta percha, do not “withdraw” the Obtura Ill MAX, but let the gutta percha ll “push” the needle out of the canal.
Pulling the needle out may cause voids and require condensation or re-work.
• Take care when bending needles, as a kink will make it all but impossible to express material. Also, repeated bending will cause needle
weakening and subsequent breakage.
• Wait for the gutta percha to come up to full operating temperature before attempting to express; material that is too cool will require much more
pressure or may be impossible to pass through a small diameter applicator needle.
• Before beginning a procedure, express about 3 cm of gutta percha so that the up-to-temperature material will be at the end of the needle;
the warm material will ll space more completely.
REPROCESSING INSTRUCTIONS
Thermal Protectors and Multi-Tool
The Obtura Thermal Protectors are designed to provide patient protection from the elevated temperatures of the heating chamber. Patient contact
requires that the Thermal Protectors be cleaned and sterilized before rst use and after each subsequent use. Thermal protectors have been tested
to a durability of 250 reprocessing cycles. Users should inspect for wear and tear and can purchase replacements as needed. Because the multi-tool
contacts potentially contaminated surfaces, it also must be cleaned and sterilized before rst use and after each subsequent use.

10. Reassemble all components in the reverse order from which they were detached. Place the handpiece back on its cradle.
WARNING: AT NO POINT SHOULD ANY PART OF THE OBTURA Ill MAX HANDPIECE BE SUBMERGED INTO THE GUTTA PERCHA
SOLVENT.
*The heater reamer tool should only be used as needed.
The Thermal Protectors must sterilized before use and each subsequent use.
HANDPIECE BUSHING
Handpiece Bushing is susceptible to wear caused by the bushing misalignment. This causes the trigger pawl to wear at the pawl engagement
opening. The bushing should be aligned in the handpiece so that bushing rotation ceases. To install the handpiece bushing, slide it in the opening
at the rear of the handpiece (diagram K), and turn clockwise until resistance is felt. The handpiece bushing should be cleaned as part of regular
maintenance and replaced as needed.
K
PLUNGER SHAFT ASSEMBLY
Areas of inspection consist of the plunger seal and the plunger teeth. The plunger seal should be inspected for wear or breakage. Gutta percha
expressed through the handpiece will give a quick and accurate indication of the plunger seal’s condition. If excessive gutta percha passes by the seal,
the plunger seal assembly should be replaced. The plunger teeth should be inspected for wear or chipping. The plunger shaft should be replaced if
plunger teeth are badly chipped or slipping occurs during testing. The plunger shaft of the Obtura III MAX should be checked for bending; if it will not roll
smoothly on a piece of glass or at tabletop (indicating a bow or bend), it should be replaced, as the use of a bent shaft may cause damage to the heater
bore.

OPERATOR’S MANUAL HEATED GUTTA PERCHA SYSTEM
Page 10
PLUNGER SEAL ASSEMBLY
To remove the plunger seal assembly, rst locate the Multi-Tool’s small hex shape opening (diagram L). Carefully insert the plunger seal assembly
within the hex shape opening, and unscrew the plunger seal assembly from the plunger shaft (diagram M). To replace the assembly, re-apply and
tighten the plunger seal assembly using the Multi-Tool’s hex utility once again. Do not over-tighten.
L
M
NEEDLE NUT
The needle nut may become filled with gutta percha, which will inhibit complete tightening and thermal transfer from the heater to the applicator
needle. Replace the needle nut if the threads become worn or are unable to be sufficiently cleaned. The needle nuts can be collected and cleaned
thoroughly at a later date for re-use. If the needle nut does become filled with gutta percha, it may indicate that the needle nut has been tightened
insufficiently. Use the Multi-Tool to assure proper fit.
HANDPIECE CABLE ASSEMBLY
The handpiece cable should be thoroughly inspected at the handpiece entry point for broken wires and cracks in the cable housing (may be due to
the frequent bending in this area). Take care not to kink the cable during use, especially at connection points. Broken wires, cracks in the housing,
or exposed wires may cause product failure. Do not use the device if any of these conditions exist. Contact us for repair. These signs are an
intermittent problem where the unit will work fine initially, but when the handpiece cable is bent, the unit stops heating altogether. The device may
exhibit other electrical faults., the error codes on the Obtura III MAX display can diagnose them (see error codes).
