2.2 Display Screens
2.2.1 Display Screens for 6 Operation Modes and Standby
2.2.1.1 EAL Mode
This mode is for canal measurement. The motor handpiece does not
run in this mode.
2.2.1.2 CW Mode
The motor handpiece rotates forward 360º, clockwise direction.

7
2.2.1.3 CCW Mode
The motor handpiece rotates counterclockwise direction only. This
mode is used to inject calcium hydroxide and other medicant. When this
mode is being used, a double-beep sounds continuously.
2.2.1.4 SGP Mode
Safety Glide Path Mode
F: Forward angle, R: Reverse angle
The rotation angle is adjustable, but the forward angle must be equal
to the reverse angle.
2.2.1.5 ATR Mode
ATR: Adaptive Torque Reverse function.
During continuous rotation movement, when torque resistance of the
instrument is higher than the pre-set torque limit the instrument will rotate
counter clockwise
2.2.2 Torque Display
This appears when the motor is running. Meter shows the torque load
on the file.

8
2.2.3 Canal Measurement Display
This appears when a file is inside the canal and the lip hook is
contacting the patient mouth. Bars in meter show the location of the file
tip. In the EAL Mode, If the length is less than 1.0, the display will be
enlarged.
The meter numbers 1.0, 2.0, 3.0 and digital numbers 00-16 do not
represent the actual length from the apical foramen. It simply indicates the
file progression towards the apex. The digital numbers -1 and -2 indicate
that the file has passed the apex foramen. The digital number “00”indicate
that the file has reached the apex foramen. Subtract 0.5-1mm from the
measured file length as the working length. These numbers are used to
estimate the canal’s working length.
2.3 Instructions for contra angle
2.3.1 The contra angle adopts precision gear transmission, and the
transmission ratio is 6:1.
2.3.2 Before the first use and after treatments, please clean and
disinfect contra angle with disinfectant of neutral PH value. After
disinfection, lubricate it with specific cleaning oil. Finally, sterilizeit
under high temperature and high pressure (134℃, 2.0bar~2.3bar
(0.20MPa~0.23MPa)).
2.3.3 The contra angle can only be used cooperatively with thisdevice.
Otherwise the contra angle will be damaged.
2.4 Installation and removal of contra angle.
2.4.1 Installation

9
Align any locating pin of the contra-angle with the positioning slot
on the motor handpiece and push the contra-angle horizontally. The three
locating pins on the contra-angle are inserted into those three positioning
holes on the motor handpiece. A “click” sound indicates that the
installation is in place. The contra-angle can be rotated 360° freely.
The contra-angle is free to rotate, adapting to the root canal of different
positions, and it is convenient to watch the screen when operating.
2.4.2 Removal
Pull out the contra angle horizontally when the motor handpiece does
not run.
Warnings:
a) Before plugging in or pulling out contra angle, please first stop the
motor handpiece.
b) After installation, please check and confirm that the contra angle
has been well installed.
2.5 Installation and removal of file
2.5.1 Installation of file

10
Before starting the device, plug the file into the hole of contra angle
head.
Hold down the push button on the contra angle and insert the file. Turn
the file back and forth until it is lined up with interior latch groove and
slips into place. Release the button to lock the file into the contra angle.
Warnings:
After plugging the file into contra angle, let go the hand on push
cover to assure that the file cannot be taken out.
Be careful when inserting files to avoid injury to fingers.
Inserting and removing files without holding the push button may
damage the chuck of contra angle.
Please use files with shanks meet the ISO standard. (ISO standard:
Ø2.334 – 2.350 mm)
2.5.2 Removal of file
Pressing the push cover, and then directly pull out the file.
Warnings:
Before plugging and pulling out the file, the motor handpiece must be
stopped.
Be careful when removing files to avoid injury to fingers.
Removing files without holding the push button will damage the

11
chuck of contra angle.
2.6 Canal measurement functional connection
This is not required if the canal measurement function will not be used.
Connect the measuring wire to the motor handpiece. Line up the
measuring wire plug with the notch on the back of the motor and push it
all the way in.
Connect the file clip plug into the socket (black) on the measuring
wire. Connect the lip hook to the socket (white) on the measuring wire.
Warnings:
Connect the lip hook to the socket (white) on the measuring wire.
Otherwise, the function of root canal preparation and root canal length
measurement cannot be used together.
2.7 Installation and removal of disposable insulation sleeves

12
2.7.1 Installation
Before each use of the handpiece and after the handpiece is cleaned
and disinfected,put on a disposable insulating sleeve. Take the insulating
sleeve out of the insulating sleeve box, then insert the insulating sleeve
into the motor handpiece from the thin end of the handpiece and install the
insulating sleeve until there is no obvious wrinkle.
After installing the disposable insulating sleeve, wrap the barrier film
around the handpiece surface. After that, clean and disinfect the surface of
the handpiece. Refer to Chapter 6.3 for cleaning and disinfection
procedures.
2.7.2 Removing
After each use, remove the barrier film and slowly pull the isolation
sleeve from the thin end of the handpiece.
Warming: Insulating sleeves are not reusable
