6
CAUTION:
•Have components been sterilized? (Refer to chapter7)
•Is the battery sufficiently charged? (Refer to chapter 5.1)
2.4Endo Motor Mode
If not any test wire connected to the device, it’s in Endo Motor Mode.
Please refer to Fig. C, D
2.4.1 Connect the Components
a) Connect contra angle
Line up the projection inside the contra angle with the notch inside the
motor and slide it in until it clicks securely into place.
b) Connect file
Hold down the push button on the contra angle and insert the file. Turn the
file back and force until it is lined up with interior latch groove and slips into
place. Release the button to lock the file into the contra angle.
c) Connect lighting device
Insert the lighting device into the motor handpiece and clip the electrode
on the file.
WARNING:
•Make sure the connection ends of the motor handpiece and the contra
angle is not damaged. If these are damaged, the load on the contra angle
could cause the motor to reverse rotation, and this might result in an
injury to the oral cavity.
•Files are expendable, and they eventually wear out. Replace them before
they break.

7
•Never use stretched, deformed or damaged files.
•Make sure the file is all the way in. Give the file a light tug to confirm it is
securely held in place. If the file is not securely placed, it could come out
and injure the patient.
CAUTION:
•Be careful when inserting and removing files to avoid injury to fingers.
•Inserting and removing files without holding the push button may
damage the chuck.
•When installing/removing the lighting device, do not shake them at will
to avoid damaging the plug.
•Take care not to touch when installing or removing the file. This
will cause the file to rotate.
NOTE:
Hold down the push button on the contra angle and pull the file straight
out.

opposite the one being treated, the file could come out and injure the
patient. Before use, run the device outside the oral cavity to make sure it is
operating normally.
b) Change Motor direction of rotation
Only in User file systems, press to change the motor direction of rotation.
NOTE:
The screen is red when the motor rotates in the reverse direction.
Means forward rotation Means reverse rotation

11
2.4.5 Auto Reverse
If, during operation the load reaches the preset torque limit value, the motor
handpiece will automatically rotate in the reverse direction. When the load is
reduced, the motor handpiece returns to normal forward rotation
automatically.
Load within the
torque limit value.
Load beyond the
torque limit value.
When the load is reduced,
the motor is automatically
restored.
CAUTION:
Do not apply excessive force. Even when using the torque reverse function,
files may break depending on the torque setting.

12
2.4.6 Change Speed and Torque
CAUTION:
•While the motor handpiece is in motion, speed and torque cannot be
changed;
•In User Recipro file system, torque cannot be changed.
•In all FKG file systems, rotation direction, speed, torque and rotation
angle cannot be changed. (fixed settings)
a) Hold down until the Speed flash and press again to select speed
or torque to adjust.
b) Press to adjust desired value.
c) The change will be saved automatically. Press to exit the setting, or
