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. It is
used for rotary files such as WOODPECKER W3-Pro.

8
2.2.1.3 CCW Mode
The motor handpiece rotates in a counterclockwise direction only. This
mode is used to inject calcium hydroxide or any other intracanal
medicament. When this mode is used, a double-beep sound will be heard
continuously.
2.2.1.4 REC Mode
Reciprocating mode.
F: Forward angle, R: Reverse angle
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 effectively.
Forward Angle<Reverse Angle, such as F:30/R:150, the effective
cutting angle is Reverse Angle, it is suitable for use of the reciprocating
files such as WOODPECKER W3-ONE.
Forward Angle>Reverse Angle, such as F:180/R:30, the effective
cutting angle is Forward Angle, it is suitable for use of the reciprocating
files such as SENDONELINE S1.
2.2.1.5 ATR Mode
ATR: Adaptive Torque Reverse function.

9
When the load on the file is greater than the set torque limit, the file
will start to rotate alternately at the set angle.
2.2.2 Torque Display
This appears when the device is operating. Display shows the torque load
on the file.

10
2.2.3 Canal Measurement Display
This appears when a file is inside the canal and the lip hook is in
contact with the patient’s lip. Bars on the display show the location of the
file tip in the root canal. In the EAL Mode, If the length is less than 1.0,
the display will be enlarged.
The numbers displayed such as 1.0, 2.0, 3.0 and digital numbers 00-16
do not represent the actual length from the apical foramen. It indicates the
file progression towards the apex. The digital numbers -1 and -2 indicate
that the file extended beyond the apical foramen. The digital number “00”
indicates that the file has reached the apical 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 adapts precision gear transmission, and the
transmission ratio is 6:1
2.3.2 Before the first use and after the treatment, please clean and
disinfect the contra-angle head with the disinfectant of neutral PH
value. After disinfection, lubricate it with recommended cleaning oil.
Finally, sterilize it under high temperature and high pressure (134℃,
2.0bar~2.3bar (0.20MPa~0.23MPa)). The contra angle should be used
only with this device. The contra angle will be damaged if there is a
mismatch with the device.

11
2.4 Installation and removal of contra angle.
2.4.1 Installation
Align one of the locating pins of the contra-angle with the positioning
slot on the motor handpiece and push the contra-angle horizontally.
When the three locating pins on the contra-angle are inserted into the
corresponding three positioning holes on the motor handpiece a “click”
sound indicates that the installation is achieved. The contra-angle can be
rotated 360° freely.
The contra-angle is free to rotate, adapting to the root canal in
different positions, and it is convenient to watch the display on the
device when operating by adjusting the position of the contra angle head.
2.4.2 Removal
Pull out the contra angle ahead away from the hand piece only after the
device is switched off.

12
Warnings:
a) Before plugging in or pulling out contra angle head, please make sure
the device is not in function.
b) Please ensure Contra angle is inserted properly into the hand
piece before use.
2.5 Insertion and removal of file
2.5.1 Insertion of file
The file should be inserted into the contra- angle head before starting the hand
piece. Press the push button on the contra-angle and insert the file. Tease
the file back and forth until it is oriented with an interior latch groove
and slips into place. Release the push button to make sure the file is
engaged properly in the contra-angle head.
Warnings:
After plugging the file into contra-angle, release the push button and assure that
the file cannot be taken out by gently pulling it.
Be careful when inserting files to avoid injury to fingers.
Inserting and removing files without holding the push button may damage the
chuck of the contra-angle.
Please use files with shanks that are in compliance with ISO standards. (ISO
standard: Ø2.334 – 2.350 mm)
2.5.2 Removal of file
Press the push button and then pull the file gently out of the contra-angle

13
Warnings:
Before Inserting and removing the file, the motor handpiece should not
be in function.
Be careful when removing files to prevent injury to fingers.
Removing files without pressing the push button will damage the
chuck of the contra-angle.
2.6 Working length measurement Assembly
Working Length Measurement Connection.
This assembly is required only when the working length is
measured or to simultaneously monitor the working length during
canal preparation.
Connect the measurement cable to the motor handpiece.
. Connect the measurement cable and turn on the device. Connect the
metal part of the connection hook to the lip clip. Make sure that the
accessories are cleaned properly before the test.
Orient measurement cable plug with the notch on the back of the
motor and secure it firmly.
Connect the file clip plug into the socket (black) on the
measurement cable Connect the lip hook to the socket (white) on
the measuring wire.

Connect the lip hook to the socket (white) on the measurement cable
io monitor working length during the root canal preparation
Installation and removal of disposable insulation sleeves
2.7.1 Installation
Before each use of the handpiece and after the handpiece is cleaned
and disinfected, a disposable isolation sleeve should be used to cover the
handpiece. Take the isolation sleeve out of the isolation sleeve box,and
cover the motor handpiece from the thin end without any obvious wrinkle.
After covering the handpiece with the disposable isolation sleeve, wrap
the barrier film around the handpiece surface, clean and disinfect the
surface of the handpiece.
