Owner's Guide
D. Handpiece
• Push the connector on the handpiece assembly into the
receptacle in the front of the unit . The connector will "click" into place
when it is fully connected . The arrow on the connector indicates
which side should be up when inserting the connector . (Fig . 3)
• Ensure the handpiece is securely connected .
E. Footswitch Assembly
• Push the footswitch connector into the receptacle in the back of
the unit . The arrow on the connector indicates which side should
be up when inserting the connector . (Fig . 4)
F. Power cord/power connection
• Plug the detachable power cord into the power adapter block .
(Fig . 5)
• Plug the power adapter cord into the receptacle on the back of
the unit . (Fig 6)
• Insert the power plug of the detachable power cord into a GFCI
outlet, preferably "Hospital Grade . " To avoid risk of electrical shock,
this equipment should only be connected to a supply mains
with electrical earth .
• NOTE: If the power plug supplied with the unit does not fit the
electric receptacle in the office, contact the dealer or an electrician .
• Check the LED below the power knob . If it is illuminated green,
the unit is ON . If it is not illuminated, rotate the power knob
clockwise to turn the unit on . The unit is shipped with the power
knob in the OFF position .
III. Operating Instructions
A. Patient preparation and positioning
The scaling process carries the potential risk for aerosol
transmission of infection. Be sure to follow appropriate
infection control procedures as recommended by health
WARNING
authorities. Please refer to Section IV of this guide for
Infection Control guidelines.
• Have the patient perform an antimicrobial pre-procedural mouth
rinse to reduce bacterial contamination of the aerosol .
• Place the dental chair in a supine position for optimal access to
both the maxillary and mandibular arches . This improves patient
comfort and increases clinician visibility .
• Position the patient's head for optimum access to the quadrant
and tooth surface being treated . Evacuate water and debris with
a saliva ejector or high-volume evacuator .
B. Ultrasonic scaling procedures
NOTE: Refer to section IV (Maintenance and Infection Control) of
these Instructions For Use for general procedures to follow daily
and between patients .
General operating procedures:
1 . Install the sterilized handpiece sheath by threading it onto the
handpiece assembly until the tapered end is flush with the end
of the handpiece . ( Fig . 7) Scaler sheaths should be sterilized
before first use on each patient per Section IV of this manual .
2 . Be sure the main dental office water supply valve is open .
3 . Turn the unit ON by rotating the power knob clockwise until a
click is heard . Verify that the green LED below the power knob
is lit . Note: Ensure that the footswitch is not depressed when
the unit is turned ON .
4 . Turn the water control knob clockwise to the fully open
position (3 full rotations) .
5 . Hold the handpiece (without an insert installed) over a sink or
drain . Depress the footswitch and flush the water line for at
least 2 minutes .
6 . Select the sterilized scaler insert . Scaler inserts should be
sterilized before first use on each patient as stated in Section IV .
Inspect the insert for any wear or damage to the laminate stack
or insert tip . Do not use a damaged insert .
7 . Hold the handpiece upright over a sink or drain and press the
footswitch until the handpiece is completely filled with water .
This lubricates the insert O-ring and helps to ensure maximum
cooling of the insert during operation .
8 . Push an insert into the handpiece using a twisting motion to
completely seat the insert into place . (Fig . 8 )
9 . Set the power control knob to the preferred operating
positions . Power settings are numbered 1 through 10 – each
increment represents a 10% change in overall power in
"Normal" mode . NOTE: Use the lowest effective power setting
possible when scaling to minimize patient discomfort and the
risk of tooth surface defects .
10 . Press the two-stage footswitch to the first position (for normal
mode) or the second position (for turbo mode) and adjust the
water control so that there is a fine mist of water spray .
NOTE: Prolonged use of the unit at high power or in turbo mode may
require an increase in water flow to prevent overheating .
C. Turbo Mode
•
The Turbo mode can be activated using the two-position
footswitch in the second (fully depressed) position . (Fig . 9)
•
When the Turbo mode is activated, the LED on the unit will
change from green to orange .
•
When the Turbo mode is activated, the output power will
instantaneously increase to 150% of the current power setting
or to the maximum power setting, whichever is lower . See the
power dial for equivalent power setting when transitioning
from normal to Turbo .
•
To exit Turbo mode, release the footswitch to first position . The
LED will return to green .
•
The Turbo feature is helpful to remove stubborn calculus and is
intended only to be used as a temporary mode of operation .
•
It may be necessary to adjust the water control knob with
the unit in Turbo mode to ensure adequate water delivery to
the tip and the tooth . Prior to use on each patient, test the
combination of intended power and water to ensure a proper
water flow is achieved at the selected power setting .
D. Helpful hints
•
Use the lowest effective power setting possible when scaling
to minimize patient discomfort .
•
If the handpiece becomes hot to the touch, there is either too
little water, too much power or both . Adjust power and/or
water settings accordingly .
•
The rubber O-ring on the insert must be lubricated with water
before placing it in the handpiece . Not lubricating the O-ring
will make proper seating more difficult . Fully seat insert by
pushing inward while twisting until seated . Do not apply
