“MR AUTO MOTOR” is a compact device combining endodontic motor with microprocessor control for working with rotating Ni-Ti instruments,Integrated "root expansion" and "root measurement" two functions.Root expansion is used for root canal shaping and cleaning equipment during root canal treatment, while root measurementis an auxiliary device for root canal treatment to measure apical length.
Scope of application
For root canal treatment only; Qualified dentists are required.
Safety measures and warnings
the PATIENT shall not be an intended OPERATOR.
never open or repair the device by yourself, otherwise void the warranty.
Prevent liquid from entering the enclosure from the enclosure.
Away from the heat source and make sure that there is no combustible surrounding.
Sterilize and disinfect each patient to avoid cross-infection.
If the micro-motor malfunctions (noise, chatter, vibration), stop using it immediately, try to find out the cause of the failure based on the information presented in Section 11.
Strictly follow the manufacturer's instructions for the use of endodontic instruments
Do not use "continuous" rotating instrument tools in a "reciprocating rotation" system, and vice versa
Do not use instruments that are bent, deformed, or inconsistent with ISO requirements.
The equipment is usually operated at a temperature of 10-35 ° C, the relative humidity of the air does not exceed 80%, the atmosphere
pressure (101 ± 3) kPa.
Safety and effectiveness have not been.
Introduction to preset mode
MR AUTO MOTOR has 10 modes P0~P9,P0 is only used for root canal depth measurement,P1~P9 can also be measured at the same time as the root expansion. As shown in Table 1.
Introduction to program features
Root canal measurement
For root canal measurement only
1 ,2, 3, 4
Forward rotation 170° / reverse 50°
Reverse 150° / forward 30°
Reverse 170° / forward 50°
Continuous forward rotation, when the load exceeds the preset value, the motor will automatically reverse 90° and forward 180° until the load torque value does not exceed the set value, and resume continuous rotation.

“MR AUTO MOTOR” is powered by a rechargeable lithium battery,The first time you use this device, fully charge the lithium battery is required.
When the display battery icon is buffered, it indicates that the lithium battery is charging.When the lithium battery is fully charged, the battery icon shows full.
Only the original adapter could be used.
Unplug the adapter from the outlet when the device is not charging.
Endodontic wireless endo motor
Battery charge indication
When the lithium battery is below the minimum allowable power(< 20%),the battery icon shows“”,Charge the lithium battery according to P4.1.
Otherwise, the device will automatically shut down when the battery drops to 10%.
Note! When the battery is below 20%, it is recommended to charge the device!!
Automatic shutdown function
Short press the power button(3- fig.3) to turn on the device, press and hold the button for about 2 seconds to turn off the device.
it will automatically shut down after 8 minutes without any operation.
