1. GENERAL INFORMATION
1.1. Intended use:
Endodontic motor “Estus Drive” is a device for the tooth root canals
preparation using:
- all types of Ni‐Ti files with continuous and reciprocal rotation and
with built-in apex locator to control the distance from the file tip to the
apical constriction (physiological apex) during the endomotor
operation;
- self-adjusting files (SAF) with simultaneous irrigation of the canal
using the pump “Estus Pump”;
- endodontic burs and brushes of the “GentleBrush File” type.
1.2. Indication for use:
“Estus Drive” is an electronic device used in dentistry for preparation
and processing of the root canal. The manufacturer is not responsible
for any dangerous situation while using the device for purposes other
than that intended.
1.3. Application field:
The device is for use ONLY in medical facilities.
1.4. Potential users: ONLY the licensed dentists.
1.5. Contraindications: “Estus Drive” is not recommended for use in
patients who have a pacemaker.
1.6. Adverse reactions: Without finding.
1.7. Contact type with a patient: Short invasive contact through the
oral cavity.

1.8. Operating principal:
Endodontic motor: the drive combined with “RT”, “SAF” or “GF”
heads allows to control endodontic continuous and reciprocal rotations
of Ni-Ti files, self-adjusting files or endodontic burs and brushes of
the “GentleBrush File” type accordingly.
1.9. Functional abilities:
 Operation with three types of the heads: “RT”, “SAF” and “GF”.
Automatic head type recognition and the following activation of the
corresponding operational mode.
Motor with “RT” head:
- Four programs (1 - 4) for operation with Ni-Ti files of the
continuous rotation with the fixed speed value and ultimate rotating
moment (torque) value for every file.
- One program (5) for operation with Ni-Ti file of reciprocal rotation
with the fixed speed value and the file rotation angles clockwise
and counterclockwise.
- Function of automatic optimal torque control “Safety Torque
Reverse” (STR) at the ultimate torque value in the mode of the
continuous Ni-Ti files rotation.
- Functions of the built-in APEX LOCATOR :
- automatic apex locator activation at the inserting file into the
canal during the endomotor operation;
- automatic motor rotation slowing at the approaching to apex
(“Apical Slow Down”);
- apical reverse (“Apical Reverse”) at the apex achieving .
- Indication on the LED scale of the handpiece:
- chosen working program before motor start;
- current torque from the motor start moment or
- the distance to canal apical constriction in the range from 2,0 to
0,0 units at closing the apex locator measuring circuit.

6
USER’S MANUAL
www.geosoft.ru/en
Motor with “SAF ”head:
- Five programs (1 - 5) for operation with SAF-files with one fixed
value of the file rotation speed and five speeds of the irrigating
solution supply with the pump “Estus Pump” connecting.
- Built-in timer of the motor and pump operation with the function of
storing the current time value, automatic zeroing of the timer after
4 minutes work and automatic motor and pump stop after 5-
minutes work.
- Indication on the LED scale of the handpiece:
- of the chosen working program before motor start,
- of the current timer value from the motor start moment .
Motor with “GF”head:
- Two programs: (1) for working with burs 6500 rpm and (2) for
working with endodontic brushes “GentleBrush File” type 3000
rpm
 Automatic calibration of the micro-motor system during the
handpiece work allows to measure and compensate the inner
friction of the micro-motor system;
 Possibility to change all working parameter of the handpiece in a
wide range of values if the handpiece is connected to the PC with
the special wireless adapter “Estus USB”;
 Audio indication during operation and function of the audio signal
volume adjustment.
 Indication of the power supply discharge.
 Power saving function.
 The possibility of expanding “Estus Drive” functionality in terms
of settings and displaying the values of its operating parameters
and the built-in apex locator values indication when the device is
operating as a part of the “Estus” dental complex together with the
“Estus Multi (Plus)”* main control unit.

1.10 Precautions and Warnings
! Use the device with the original “Geosoft Dent” accessories only
(see section 3).
!Do not disassemble or modify the device. Violation of the device
integrity cancels the warranty.
!Avoid letting any liquid inside the product’s housing.
!Do not use the device close to flammable agents. The device is not
suitable for use in presence of flammable anesthetic agents with air,
oxygen or nitric oxide.
!Use sterile and disinfected parts and accessories of the device only.
Sterilization and disinfection must be conducted directly before the
initial use and also between each time of use to avoid cross infection.
(for more details see section 8).
!Be sure to lubricate and sterilize the motor head before first use and
between each patient use. Avoid getting oil on exposed parts of the
motor.
!When working in the patient's oral cavity, use a rubber dam.
!If any deviations from the normal operation of the endomotor are
detected (noise, vibration, heating, etc.), immediately stop using the
device and try to find out the cause of the failure, based on the
information presented in section 10 of this manual.
! The endomotor offers the function of Ni-Ti file torque limitation in
the continuous rotation mode, which decreases the file breakage
during the processing. Setting of the wrong torque value and using the
life-expired file could cause the file breakage. Carefully follow the
manufacturer’s instruction and avoid using the life-expired or
damaged files.
! Do not use the curved, defected or not corresponding to ISO
standards file. Using such file could cause injury.

USER’S MANUAL
www.geosoft.ru/en
!Always clean the shank of the file to be set. The contaminated head
clamp mechanism could cause improper file fixation in the head and
also the contact loss and violation of the measuring circuit continuity
of the in-built apex locator.
!Do not start the motor until the file is not reliably set in the head
clamp mechanism.
!Avoid casual contact with the motor rotating parts and/or rotating
file.
!In some cases detecting apex with the built-in electronic apex locator
could be inaccurate and unreliable. (see section 7 Basic rules of work
with apex locator). Prior to using combined mode (motor and apex
locator) with “RT” head, it is recommended to make an x-ray and rely
on the information got by both methods.
! This device requires special measures application for
electromagnetic capability (EMC) and should be installed and
switched into operation accordingly with the information in the
Appendix of the User’s Manual. It includes the requirement not to use
the device close to daylight lamps, radio transmitting equipment and
remote controls.
! The buit-in apex locator dysfunction is possible if used in
electromagnetic interference (EMI) area. Do not use the device close
to the electromagnetic equipment. This equipment is usually marked
by the sign
!Do not use the device jointly with the different equipment or as a
part of the equipment, not included into the manufacturer’s product
list.
!Do not use the accessories, adapters and cables, different from the
listed below. It can direct to the emission interference increase or
reduce interference immunity of the device. The Manufacturer
guarantees electromagnetic compatibility of the following accessories:
apex locator cable of the maximal length 105 cm; the charger cable of

9
ESTUS DRIVE
www.geosoft.ru/en
the maximal length 1.8 m.
! The device operates normally at a temperature of 10-35°С, relative
humidity of air not more than 80%, atmospheric pressure (101±3) kPa.
Any violation of these restrictions may cause the device error.
