“MR AUTO MOTOR” is a compact device combining endodontic motor with microprocessor control for working with rotating Ni-Ti instruments It is integrated "root expansion" with "root measurement". Root expansion is used for root canal shaping and cleaning equipment during root canal treatment, while root measurement is 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 the warranty gets void.
Prevent liquid from entering the enclosure .
Keep it away from heat source and make sure that there is no combustible in surroundings.
Sterilize and disinfect 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 User Manual 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 and the relative humidity of the air does not exceed 80% of the atmosphere
Pressure: (101 ± 3) kPa.
Introduction to preset mode
MR AUTO MOTOR has 10 modes P0~P9.P0 is only used for root canal depth measurement.P1~P9 can measure whilst conducting root expansion. As shown in Table 1.
Program feature introduction
Root canal measurement
For root canal measurement only
1 ,2, 3, 4
clockwise rotation 170° / counterclockwise 50°
counterclockwise150° / clockwise 30°
counterclockwise 170° / clockwise 50°
Continuously rotate clockwise.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, that fully charge the lithium battery is required.
When the display battery icon is buffered, it indicates that the lithium battery is charging.When 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.
Battery charge indication
When the lithium battery percentage is below the minimally allowable power(< 20%),the battery icon shows“”,Charge the lithium battery .
Otherwise, the device will automatically shut down when the battery drops to 10%.
Please be noted that when the battery is below 20%, it is recommended to charge the device!!
Automatic shutdown function
Short press the power button 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.
