• Compact design.
• Able to operate for approx. 2 continuous hours at the rated load. (Dependent upon use conditions.)
• A large LCD panel enhances ease of use.
• Programmable up to 9 memory settings.
• The auto reverse function is activated depending on the load. A wide variety of functions such as “auto reverse”,
“auto stop” and “auto reverse off” are available. Combined with such functions nine different operation programs
are memorable.
• The rotation of the motor handpiece can be activated by the ON/OFF button of the motor handpiece or the Foot
Control (optional).
• The motor handpiece can be turned on and off by pressing the ON/OFF button alternatively. In addition, ON by
keep depressed and OFF by releasing it is possible.
• The motor handpiece softly starts. Since it makes a brief stop before it starts in the reverse rotation, there are no
vibration and shocks during this change over.
• The built in feedback circuit maintains rotation at a constant speed even when the load on the motor handpiece
changes.
• Has energy saving feature. The power of the motor handpiece automatically turns off when not being used for 10
minutes. (Auto power-off function)
• The contra angle heads provided for this product are all autoclavable up to 135°C (excluding the motor
handpiece).
1. FEATURES
• During rotation, the motor handpiece and the motor handpiece cord may affect computer and LAN cable. Noise
could be heard during operation near a radio receiver.
• The motor handpiece consumes electricity very slightly even when the power supply is off. In addition,
fully-charged rechargeable batteries, in general, discharge gradually over time even though it is not used. It is
recommended to recharge the batteries just before use.
• When the motor handpiece stops automatically by detecting a low battery voltage, turning on the power again
after a while may not detect the low voltage immediately. This is not a failure, but due to battery characteristics.
The voltage drop does not coincide with the remaining battery capacity.
• Recharge rechargeable batteries after they deplete as much as possible. Repeating short-time use and
subsequent recharging may shorten their operating time due to the “memory effect.” Batteries may recover after
repeating complete discharge and full charge for a few times. (This product is equipped with a “Refresh Mode”
for this purpose.)
• The used Nickel Metal Hydride Batteries are recyclable, but their disposal may sometimes not be permitted by
the country. Return them to Brasseler USA.
• When disposing of the control unit and Foot Control (Option), follow the instructions of your local government for
disposal, as they contain materials which may become industrial waste.
• When discarding the contra angle head and motor handpiece, dispose of them as medical waste.
• Users are responsible for operational control, maintenance and inspection.
• Store the system in the place where the temperature is at -10-60°C (14-140°F), humidity at 10-85% RH,
atmospheric pressure at 500-1060 hPa, and the system is not subject to air with dust, sulfur, or salinity.
• When trouble is found, contact Brasseler USA.
• This product does not consider patient’s age (except infants), gender, weight or nationality.
• No special training is required for this device.
• EndoDrive PLUS should not be used adjacent to or stacked with other equipment and that if adjacent or
stacked use is necessary, EndoDrive PLUS should be observed to verify normal operation in the
configuration in which it will be used.

(1) Charge (if batteries are used)
1) Insert the AC adapter plug into a power supply.
2) Confirm the AC IN lamp light is green.
3) The internal microcomputer checks the voltage of the batteries and starts charging, if necessary. If it starts
charging, the CHARGE lamp lights, and the mark of the remaining amount of the batteries on the LCD panel will
be animated.
* There is no need to turn on the power.
4) When the CHARGE lamp turns off, charging has been completed.
5. HOW TO USE
• Do not connect other than AC120V or AC 230V. If it connects to others, it may cause a malfunction.
• Since the AC IN lamp lights up to indicate that the supply power is on, it does not go out even after a charge
is completed. See the CHARGE lamp to check the charging conditions.
• The charging normally takes approx. 5 hours, but it depends on battery use conditions. Older batteries are
especially prone to significantly shorter charging and operating times.
• The temperature of the batteries is measured during charging. Proper charging cannot be preformed if the
charger is placed in an environment which is subject to sharp temperature change (next to window, subject
to direct sunlight, near air outlet or fan heater). Place it in a place where temperature change is minimal.
• Charging may not be started in the following case:
• The temperature of a battery is too low or too high. (less than 0°C (32°F) or more than 40°C (104°F). )
• The temperature of the batteries is executively high or low. (Lower than apporox. 0 degree or higher than
approx. 40 degree)
•A battery is not connected.
• The voltage of a battery is abnormal. (See P.16 10. “ERROR CODE”)
• Batteries are automatically charged depending on conditions, even when the power is on. But when the
motor handpiece is used, charging is suspended to protect the battery.

handpiece is in motion, even if it is not used.
NOTICE
AUTO REVERSE OFF
The motor handpiece stops without reverse rotation. In this instance, the LCD panel shows “ ” and the
rotation speed alternately.
• When the reverse rotation (R) is set, the Auto Reverse Function is not activated.
• When the batteries go down (when the mark of the remaining amount of the batteries indicates “ , ”),
the actual load may not reach the preset torque limit value. In this case (in the case of operation by batteries),
this auto reverse function will not be activated. When high torque is required, use the AC adapter or use this
product in a condition where the batteries are not significantly consumed (when the mark of the remaining
amount of the batteries indicates “ , ”).
• If a load is continuously applied to the motor handpiece, it may automatically stop to prevent overheating. (The
torque limit value indicates “ ” on the LCD panel). In this case, leave the motor handpiece for a while until it
cools down. When the display returns to normal, the motor handpiece can be used.
NOTICE

(4) Calibration
This function is to decrease fluctuation in the rotation speed of the motor handpiece and the difference in torque by
the contra angle head.
1) Lubricate the contra angle head with the spray. (Refer to the “P14 7. (1) Lubricating Contra Angle Head.”)
2) Turn off the power if the power is on.
3) Connect the AC adapter and confirm that the AC IN lamp lights.
4) Turn on the power.
5) Hold down both buttons of the SPEED key simultaneously for more than one second.
6) The LCD panel displays “ ” with the alarm sound.
7) Attach the contra angle head to the motor handpiece and press the MEMORIZE key.
8) If the motor handpiece begins to rotate, leave it as it is until it stops.
9) This process ends, if the rotation stops and the LCD panel display returns to its original state.
10) If you want to stop this process, turn off the power.
(3) Battery Refresh
Nickel-metal-hydride batteries may result in a decrease in charging capacity, if additional charging (repeating a cycle
of short-time use and recharging) is made. (Generally, this phenomenon is called a “memory effect.”) This Battery
Refresh function is to resolve this phenomenon.
1) Turn off the power if the power is on.
2) Connect the AC adapter and confirm that the AC IN lamp lights.
3) Hold down the POWER key for more than one second, while pressing the REVERSE key.
4) The alarm sounds for a length of time, and the refresh mode is activated. At this time, the mark of the remaining
amount of the batteries on the LCD panel is animated in the direction opposite to display at the time of charging.
At the same time, the CHARGE lamp flashes slowly.
5) Leave it as it is. The batteries are discharged and recharged automatically.
6) Hold down the POWER key for a while, when you want to stop this process. (At this time, the power does not turn on.)
• Lubricate the contra angle head before Calibration.
• This function does not operate if AC adapter is not used.
• Do not touch or apply a load to the rotating shaft of the contra angle head. It obstructs accurate measurement.
• This function cannot completely absorb the individual difference of the actual motor handpiece and contra angle head.
NOTICE
• This function is not activated unless this product is powered by the AC adapter.
• If this function is used, all programs will disappear and return to the originally set values. Record the present
program details according as needed.
NOTICE
• This function is not activated, if not driven by the AC adapter.
• It may take up to 5 hours to discharge batteries.
• It takes 5 hours to discharge and 5 hours to recharge. Therefore, total of about 10 hours are required. For
example, if dental treatment is finished at 7 p.m. and the refresh mode is set, the batteries will be fully
charged by 5 a.m. the next morning at the longest.
• This function is not required for each charging. Try this function, if the operating time is shortened even if the
batteries are relatively new.
• Do not repeat activation and deactivation of the refresh mode in a short time. It may result in enhancement of
the memory effect.
• This function is fully effective for solution of a “memory effect.” However, it cannot be solved completely at
one time due to characteristics of batteries. We recommend you repeat this process a few times according
to need.

• To clean the motor handpiece, do not use any solvent such as benzine and, thinner.
• Before mounting the lubricated contra angle head to the motor handpiece, wipe off extra oil. Stand on its end or
lean it in the proper position for gravity draining. Mount it after excess oil has been drained.
• Hold the contra angle head securely to prevent it from flying off by the pressure of the spray.
• Supply lubricant until it comes out of the handpiece head (for approx. 2 seconds).
• Do not use a spray can upside down. In such a case, only spray gas comes out and oil is not sprayed.
CAUTION

The motor handpiece uses rechargeable batteries. They can be recharged 300-500 times, depending on the use conditions
of the motor handpiece. If the operating time or recharging time becomes shorter or the rotation power becomes weaker,
although the “memory effect” described in “ NOTICE” is not applicable, the life of the batteries is depleted. In such a
case, ask your dealer to replace the batteries or replace them with new ones yourself. (Refer to the “ Changing Batteries.”)
When replacing them yourself, be sure to observe the following “ CAUTIONS ON CHANGING BATTERIES.” Note that
Brasseler USA shall not be held liable for any malfunction or failure resulting from your not following the
“ CAUTIONS ON CHANGING BATTERIES.”
* we recommend our genuine Brasseler USA Batteries.
