Features
Features and intended use:
The Tri Auto mini is a compact, cordless endodontic treatment motorized handpiece for preparation and enlargement of root canals.
It may be connected to the Root ZX mini, an apex locator (sold separately).
Instructions for how to use the Tri Auto mini when it is connected to the Root ZX mini are printed on a blue background like this one.
⹅Liquid Crystal Display (LCD) :
The LCD is easy to read and shows all settings as well as how the motor is running.
⹅Controls :
Speed : Eleven rotation speeds can be set from 50 to 1,000 rpm.
Torque Reverse : The motor automatically reverses its rotation if the torque load exceeds the set value to reduce
the risk of jamming.
Slow Down : The le slows down as torque increases.
The le slows down as it approaches the apex if the Tri Auto mini is connected to the Root ZX mini.
Forward & Reverse : The le may rotate in both forward and reverse directions.
Auto Start & Stop* : The le starts when it is inserted in the canal and stops when it is taken out.
Apical Reverse or Stop* : The motor reverses or stops when the tip of the le reaches a preset position inside the canal.
Apical Torque Reduction* : The automatic torque reverse value is reduced as the le tip approaches the apex.
* These controls can be used if the Tri Auto mini is connected to the Root ZX mini.
⹅Memory:
Six combinations of speed, torque etc. can be memorized.

* If the unit has not been used for some time, make sure it works properly before using it again.
The battery is built into the motor handpiece.
• The battery is not charged when the unit is shipped from the factory and must be charged before using the unit.
• Do not pull or yank the cord when disconnecting the AC adapter. Always grip the connectors.
• Use only the power cord provided and plug both ends all the way in.
• Charger and power supply cord must be located outside the so called patient environment (2.0 m around the patient location).
• If an electrical storm occurs while the battery is being charged, do not touch the charger or its cord as there would be a risk receiving an electric shock.
• Do not get the charger wet or use it where it might get wet.
Usage
⹅Operation Conditions for the main unit and AC adapter
Charge the battery as soon as the battery power indicator gets down to its last bar.
If the orange charge LED goes off immediately or doesn’t light up when the handpiece is put into the charger, the battery is probably fully charged.
To make sure, take the handpiece out and put it back in again.
Make sure the contact areas for the handpiece and charger are free of debris, especially metal fragments. Wipe with ethanol to remove any foreign debris.
Do not press down too hard to wipe the charging areas; this could bend the electrical contacts.
Do not leave the charger where it will be exposed to direct sunlight.
Do not use any charger; use only the one that comes with the Tri
Auto mini.
Connect the power cord to the charger and then plug
it in. Turn the charger on. The green Power LED will
light up.
* Ambient (room) temperature for charging is from 10ºC (50ºF) to 40ºC (104ºF).
Put the handpiece into the charger as far as it will
go. The orange Charge LED will light up to show that
charging has begun.
* Charging time is about 120 minutes.

Connect Contra Angle
Charge Battery
The number of bars shows how much battery power is left.
Recharge the battery when there is only one bar left.
If the battery runs almost completely out, the Tri Auto mini will automatically turn itself off after
about 10 seconds. Recharge the battery as soon as possible.
If the battery power is very low and a large load is applied to the le, the motor may stop or the
unit may turn itself off.
This is for safety; there may not be enough power to run the motor with sufcient stability.
Recharge the battery if the display shown to the left appears frequently.
Contra Angle Motor Handpiece
Line up the marks.
Approx. 290°
Do not force the contra angle to rotate beyond its limit.
The rotation range of the contra angle is about 290°.
Set it so that it reaches the treatment area and the
display is easy to see.
Line up the match marks and push the contra angle onto the handpiece until there is an audible click.
* The contra angle must be lubricated with AR Oil before using for the rst time. Refer to “Lubricate the Contra Angle with
AR Oil”.
• Push the contra angle all the way onto the handpiece and then give it a light tug to make sure it is securely attached.
• Make sure the connection components for both the handpiece and the contra angle are not damaged. An improper connection could cause the motor to
reverse unexpectedly and result in injuring the patient.
