5. To connect the piezoelectric scaler handpiece to the cord, align the pins on the
handpiece with the cord coupler and gently but rmly push the handpiece into the
cord coupler. Do not twist, turn or unscrew the handpiece while inserting into or
removing from the cord coupler. Then select the suitable scaling tip needed and
screw it on the handpiece tightly by using the torque wrench (Figure 7.1)

Figure 10: Turn on the compressor
using the red knob. Gauges are visible
to monitor compressor pressure. The
optimal pressures provide optimum
efciency and safety of the unit.
Pressure gauge should indicate
between 80 psi (5.5 bar) and 108
psi (7.5 bar). The compressor will
automatically stop when the pressure
reaches 108 psi (7.5 bar).

switch (when the low power supply
voltage and load startup, may trigger
overload protector to cut off the motor’s

8. Daily Cleaning and Maintenance
8.1 Unplug unit from wall out and wipe down unit, cords and handpieces with water
and non-chloride non-iodine disinfectant. Use a solution that does not contain
chloride or iodine to prevent staining of the unit.
8.2 The suction hose is exposed to pathogenic secretions, saliva and blood on a
daily use. Therefore, for hygiene reasons, the used suction hose must be cleaned
after each operation, especially if bleeding occurs during the operation. If treatment
is prolonged, the suction hose must be cleaned at least once every 120 minutes,
and once every day on and off work.

14
Warning: The capacity of the suction bottle is 1L. However, it is recommended
to empty and clean the suction bottle after each use. Suction bottle should be
cleaned out before exceeding 500 ML point or risk of contamination may occur
if suction gathered uids spill.
Instrument and hose Cleaning Bottle I/ Bottle II
In order to reduce the amount of bacteria in the waterline,
water can be used to clean the treatment instruments air
water syringe
Frequency of cleaning
Daily before starting the work day and again, at the end of
the work day.
Air water syringe a. Take out the air water syringe from the holder
b. Put the air water syringe over a sink or a bucket
c. Press the water button of the air water syringe for 20-
120 seconds (until water no longer sprays from the tip)
d. Put the air water syringe back on the holder
Handpiece Cords 1. Remove the High Speed Handpiece and Low Speed
Handpiece from the holder
2. Disconnect the handpiece from the tubing cord
3. Adjust the water regulator for all equipment to
maximum ow
4. Put the treatment cords over a sink or a bucket
5. Step on the foot pedal for 20 to 120 seconds to wash
the waterline of the treatment instrument
6. Put the handpieces back on the holder
Foot Pedal Improve its stability by regularly cleaning the foot switch
• Clean the pedal by a damp cloth or water
Dirt cup The instrument oil is collected in the dirt cup
• The dirt cup needs to be clean after daily use
• Clean the dirt cup weekly with a mild commercial cleaner
Suction system
(Model C2 and C4
do not have this
function)
1. Put 0.6L of cleaning liquid into a separate container and
mix well
2. Remove the extraction handle and start suction to make
the cleaning solution work. Pay attention to the cleaning
solution time specied by the manufacturer.
3. Drain the suction bottle cleaning solution and clean the
suction plastic bottle, reinstall the equipment.

8.3 High Speed and Low Speed Handpieces Lubrication
Oil High Speed and Low Speed handpieces prior to rst use, and oil after every
use.
1. After cleaning the handpiece, apply lubricant before sterilization. lubricant is
placed in the smaller of the 2 large holes at the base of the handpiece. Use only a
high quality lubricant such as BeyesLube.(Figure 11)
2. Flush through with air for 30-45 seconds and wipe any excess lubricant from
handpiece.
3. Place the handpiece in a sterilization pouch and follow your country specic
directives, standards, and guidelines for sterilization temperature and times.
(Figure 12)
8.4 Piezoelectric Scaler and Handpiece Daily Cleaning
Disconnect the cord and Piezoelectric handpiece and clean handpiece with a
disinfectant (non-chloride, non-iodine). Do not immerse in any solution, including
ultrasonic or cold sterile solutions, as this will damage the handpiece and void
Warranty. Make sure to remove any tips from the handpiece prior to sterilization.
1. Dry handpiece with a clean cloth
2. Place handpiece in sterilization bag and sterilize for 3 minutes at a maximum of
135 °C (Figure 12)
*Additional handpieces and tips can be purchased to accommodate sterilization turn
around time.

8.5 Compressor
1. Open the drainage mechanism at the bottom of the air purge valve to empty the
water inside. (Figure 13)
2. At the end of the day, turn off the machine and unplug the electrical outlets.
3. Loosen the screw on the drain valve below the tank to remove all pressure (a dry
cloth is recommended to avoid getting wet). This will also eliminate condensation
and extend tank life. Don't forget to tighten the screws before starting a new day.
(Figure 14)
4.As for the backow from high-speed air, the oil in the air is collected in the dirt
cup. It is recommended to drain once a day. Please check the level of the dirt cup
and empty it if necessary. (Figure 15)
Figure 13 Figure 14 Figure 15
9. Troubleshooting Guide
9.1 Error: No Power
1. Ensure the power cord is plugged into a live wall circuit of the appropriate voltage
2. The machine end is rmly plugged into machine
3. The main switch is on
4. Ensure the overcurrent protector hasn’t popped
9.2 Error: The tank will not pressurize
1. Ensure the compressor on/off switch is in the on position
2. Ensure the drain valve is closed
3. Ensure the safety purge valve is closed
4. Check the tank pressure is set correctly
9.3 Error: Not getting the correct pressure at the tools (M4 lines)
1. Check that the correct output pressure is set at the regulator on the compressor
2. Check the drive air pressure regulator

17
9.4 Error: No water output
1. Ensure both bottles are fully connected to the system (they don’t both have to be
full but both must be connected for the system to pressurize)
2. Check that the system is pressurized via the switch is on the left side of the tray
top (if you hear a hissing noise from the bottles after pressurizing the system check
that the bottles are screwed on all the way)
3. Make sure the correct bottle is selected at the toggle switch (left side in front of
the pressurize switch)
4. Check the water switch on the foot pedal is in the correct position
5. For tools controlled via foot switch: check the water pressure regulators on
the right side of the tray top (they control water volume going front to back of the
machine controls the hoses from left to right.)
9.5 Error: Dental instrumentswill not work when the foot switch is pressed
1. Check that the selector switch (in the tool holder) is working (there is a switch in
each of the tool “holsters” which allows that tool to be used)
2. Adjust pressure regulator on underside of tray top (the front most dial controls the
chip air, while the rear controls the tool drive air)
3. For the scaler make sure that the control knob for the strength of the vibrations is
turned to the correct amount.
9.6 Error: No suction
1. Make sure you are fully depressing the small push button switch on the foot pedal
2. Ensure the suction control valve on the handpiece is at least partially on.
3. Check that there is not a blockage in the suction line
9.7 Error: The compressor is louder than usual (note the compressor will
always make some noise when running)
1. Make sure the mute lter on the compressor is in place
2. Check the anti-vibration devices that are between the compressor motor and the
tank are in place.
3. Check that all screws in the bottom half of the cart are tight.
9.8 Error: The Compressor motor and area are too hot (especially if the
compressor shuts down)
1. Make sure the compressor has proper ventilation (you can’t cover the vents or
stop the air from circulating around the compressor it needs to breathe)
Note: For any errors experienced that are not found on this guide, please contact
