Specific Instructions

POWER: Switches the device on or off (LCD screen lights up or goes out) VOLUME: Adjusts the sound volume or mute
STORAGE: Saves the current setting data of speed, torque, auto reverse and root tip limit value into program
APEX SETTING: Sets the root location (in M4 mode, file will be auto reverse when arrives the pre-set root location )
MODE: Switches the 4 operation modes M1: Only root-canal length measuring M2: Only root-canal enlargement
M3: Reciprocating rotary motion
M4: Both root-canal length measuring and enlargement M5: Both reciprocating rotary motion and length measuring

PROGRAM: Switches the programs and show the data from corresponding ones on screen.
SPEED SETTING: 200~600 rpm TORQUE SETTING: 0.6Ncm-4.0Ncm
MOTOR WORKING MODE: Switches the 3 operation modes of file.

File will stop when the stress is more than setting torque data.

When the stress is more than setting torque data, file will auto reverse. If remove the stress, file will stop.

When the stress is more than setting torque data, file will auto reverse. If remove the stress, file will forward roll again.

Manual forward or reversal switch: Change the rolling direction once press

Handpiece Bottom: Control the handpiece to work or stop with two modes:

1. Short pressing for working, again for off.
2. Continuous pressing for working, releasing for off.

The installation and use of M1 mode

Insert the plug of the measuring wire into the left side socket of the unit. Insert the file clip and lip hook respectively into the two sockets of the measuring wire. （Fig.4.3)

Attention: Do not draw the wire when inserting or pulling out measuring wire.
（Fig. 4.4a incorrect operation. 4.4b correct operation.）

1. Make sure the measuring wire is inserted correctly.
2. Make sure the measuring wire is connected with file clip and lip hook.
3. Make the lip hook touch the bent wire of the file clip (as showed in Fig. 4.5a), the screen will show the length of root canal, as showed in Fig. 4.5 (b), with beep sound.

1. The white region of instruction bars on the screen is the front region of the apical foramen. (Fig. 4.6a)
2. The file position is near by the apical foramen when the green bars displayed. (Fig. 4.6b)
3. The file exceeds the apical foramen, the bars reach red zone and make a continuous beep sound. (Fig. 4.6c)
4. The number on the screen doesn’t stand for the distance to apex, but only the trend moving toward or away the apex.

Operation

Insert the plug of measuring wire into the left side socket of main unit. Turn it on. The screen will display the measuring interface.
The instrument will automatically shut down after 5 minutes without operation or pressing SWITCH OFF button.
Press the volume button to control volume of beep sound.
Hang the lip hook on the lip, and make sure that it contacts the oral mucosa as a reference electrode. (Fig. 4.7)
Clip the metal part near the file shank vertically with the file clip, and then push the file towards to the apex slowly, the continuous alarm will sound when the distance is less than 2mm.

When the file reaches the apical position, adjust the rubber piece of the file set to the reference point (incisal edge or fossa edge), then pull out the file, measure the length between the file tip and the rubber piece. And the length is the working length of the tooth. File clip can be replaced by touch probe if it is inconvenient to measure the back teeth. (Fig. 4.8)

Installation and operation of M2

1. Align the cord plug with the connector at the left side of the device and insert the plug until it locks.
2. Align the positioning pins of the contra-angle with the positioning slots of the motor handpiece and insert the head until it clicks. Insert the file into the chuck.
3. Switch on and screen starts to display
4. Select speed of rotation, torque and motor working model. You can also press the program key directly to switch out the previously stored settings.
5. Press the key on handpiece to start
6. Torque value will be displayed on screen when （Fig. 4.9）
7. Press switch button to switch direction of

Installation and operation of M3

1. Same way to install and switch on handpiece as mode M2.
2. In M3 mode, file starts reciprocating rotation with positive turn 170°, reverse 50°. The speed is about 300rpm.

Installation and operation of M4

1. Same way to install and switch on hand piece as model M2.
2. Same settings of rotation speed and torque as model M2.
3. Press APEX key to set the apex location. （Fig. 4.10）
4. Wear the silicon rubber case, and insert the single-head measuring wire into hand piece, then insert the lip hook into the socket of the single-head measuring wire to hang the lip hook on the mouth of patient.
5. When the file into the root canal, it starts positive rotation. Slows down rotation speed when it comes to root top. Starts to reverse rotation when it comes to apical point which was set. Back to original rotation speed when away the root top. Stops when away root canal.
6. It will automatically reversely rotate once real torque was over setting number. Unload and it will get back to positive rotation.

Installation and operation of M5

1. Same way to install on handpiece as mode M3.
2. Same settings of rotation speed and torque as mode M3.
3. Press APEX key to set the apex location. （Fig. 4.10）
4. Wear the silicon rubber case, and insert the single-head measuring wire into handpiece, then insert the lip hook into the socket of the single-head measuring wire to hang the lip hook on the mouth of patient.
5. There is no need to press the STAR/STOP key on handpiece. When the file enters root canal, it starts reciprocating rotation with positive turn 170° & reverse 50°, and starts to reverse rotation when it comes to apical point which was set. Back to original reciprocating rotation when away the root top. Stops out of root canal.

Attention：

Due to root canal infection and other reasons, the root canal may be in a dry state, and the automatic rotation function will not work. In this case please inject liquid into root canal, such as hydrogen peroxide or saline. (Attention: no liquid overflow from the root canal.)
Excessive force can cause the file stuck in the root canal side wall.
A malfunction of the machine will cause rotation problem. In this case please watch on screen and operate it according to the touch feeling.
As the metal aging, file can be broken. Please timely replace it according to the requirements of the manufacturer.
When the file contacts with the patient’s oral mucosa or teeth, the motor will automatically rotates which can harm the patient.
Pressing the front button of handpiece during the treatment will cause file fall off which can harm the patient.
