2.2 Display Screens
2.2.1 Display Screens for 5 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. Used
rotaty les likes DENTSPLY Protaper or WOODPECKER W3-Pro.
2.2.1.3 CCW Mode
The motor handpiece rotates counterclockwise direction only. This

8
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 REC Mode

F: Forward angle, R: Reverse angle
Adjustable every 10 degrees, adjustment range: 20º-340º.
It is suggested that the difference between the forward angle and
reverse angle should be greater than or equal to 120 degrees, otherwise,
root canals cannot be prepared eectively.
Forward Angle<Reverse Angle, such as F: 30/R: 150, eective cutting
angle is Reverse Angle, it is suitable for used the reciprocating les likes
DENTSPLY WAVEONE or WOODPECKER W3-ONE.

Normal continuous forward rotation, the forward angle can be
stepped by 10°, the angle is set between 120°-340°, and the reverse angle
defaults to 90°. When the load of the le is greater than the set torque
limit, the le will start to rotate alternately at the set angle.

2.2.2 Torque Display
This appears when the motor is running. Meter shows the torque load
on the le.
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 le
tip.
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 le 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 le 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, sterilize
it 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 this

10
device. Otherwise the contra angle will be damaged.
2.4 Installation and removal of contra angle.
2.4.1 Installation
Line up the notch inside the contra angle with the projection inside
the motor handpiece and slide it in until it clicks securely into place.
The contra angle rotates 360° so that the OLED display can always
be viewed easily.
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 rst stop the
motor handpiece.
b) After installation, please check and conrm that the contra angle
has been well installed.
2.5 Installation and removal of le
2.5.1 Installation of le

11
Before starting the device, plug the le into the hole of contra angle
head.
Hold down the push button on the contra angle and insert the file.
Turn the le back and forth until it is lined up with interior latch groove
and slips into place. Release the but-ton to lock the le into the contra
angle.
Warnings:
After plugging the file into contra angle, let go the hand on push
cover to assure that the le cannot be taken out.
Be careful when inserting les to avoid injury to ngers.
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 le
Pressing the push cover, and then directly pull out the le.
Warnings:
Before plugging and pulling out the le, the motor handpiece must be
stopped.

12
Be careful when removing les to avoid injury to ngers.
Removing files without holding the push button will damage the
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.
