6.
Lubricate the O-ring with water before placing the insert into
the handpiece. Depress the foot switch pedal while filling the
handpiece with water and slowly turning the insert until it
snaps into place. (Fig. 7)
7.
Set the power and H
operating positions. NOTE: Use the lowest effective power
setting possible when scaling. (Scaler inserts should be
sterilized before first use on each patient. See section IV,
part A.)
C. "Turbo" feature
• The "Turbo" button on the bottom left corner of the unit may
be depressed to switch to maximum power, without having to
adjust the preferred power setting. When the "Turbo" mode is
selected, a yellow LED above the button will be lit.
• It is not possible to adjust the power with the power knob as
long as the "Turbo" is on.
• To turn the "Turbo" mode off, depress the button again. The
yellow LED will not be lit.
• The "Turbo" feature is helpful to remove stubborn pieces
of calculus, and should only be used as a temporary mode
of operation.
• It may be necessary to adjust the H
"Turbo" mode to assure adequate fluid delivery to the tip and
the tooth.
D. Helpful hints
• Use the lowest effective power setting possible
when scaling.
• 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 FORCE.
The handle on the insert should be flush against the handpiece.
Alternatively, lubricating the O-ring with a small amount of
petroleum jelly could prolong the life of the O-ring.
• Check and verify that fluid is reaching the working end of the
insert tip by holding the handpiece over a sink or drain and
activating the unit. Adjust the H
adequate flow is achieved for the selected power setting. A
fine mist should be spraying from the scaler insert tip (Fig. 8).
• If water fails to flow properly, check supply line filter for
clogging. Filters are disposable. Replace if necessary. Do not
attempt to unclog used filters.
• To prevent accidental contact with the lips, tongue, and cheek,
the scaler insert should be activated just before contacting
the tooth, but after the insert has been placed in the
patient's mouth.
• It is best to hold the handpiece in a pen grasp, using a very light
touch when scaling both supra and subgingivally. Too much
pressure of the tip against the tooth surface will decrease the
effectiveness of the insert, as tip vibration is obstructed.
• Periodically check the scaler insert for wear.
• Develop an operating sequence in scaling to ensure
thoroughness, and to minimize adjustments in patient and/or
operator position.
E. Patient discomfort can be caused by:
• Excessive pressure. Apply the side of the scaler tip gently to
tooth surface using very little pressure.
• Incorrect tip positioning. Avoid contact of the scaler insert tip
and the tooth. Direct the tip away from root surfaces, and use
side of scaler insert only.

• Not keeping the tip in motion on tooth. The tip should always
be in motion during scaling. Use vertical, horizontal, or
oblique overlapping strokes to increase scaling efficiency and
decrease discomfort.
• If sensitivity persists, alternate treatment of sensitive areas and
less sensitive areas and/or decrease power setting.
IV. Maintenance and Infection Control
A. Before each patient
1.
Use a sterilized ultrasonic insert for each patient. (Scaler inserts
should be sterilized before first use on each patient. Follow
sterilization directions on scaler insert packaging.)
2.
Clean and disinfect the surfaces of the cabinet, unit, power
cord, and handpiece with Alpet D2 or BioSonic Wipeout.
Apply barrier sleeves to the unit and the handpiece to reduce
the risk of cross-contamination.
3.
Flush the water supply lines as discussed previously in
section II.
4.
Place the sterilized scaler insert into the handpiece while
maintaining proper asepsis techniques.
B. At the end of each day
1.
Remove all ultrasonic inserts, clean and sterilize as applicable.
2.
Clean and disinfect the unit and peripherals as done before
each patient. Clean components by wiping with a soft cloth
moistened with a commercially available mineral deposit
remover followed by an intermediate level disinfectant.
CAUTION:
Do not use petroleum based solvents, iodophors or
phenolic based products. (Iodophors and phenolics can stain the
surface of the unit.) Clean up all liquid spills immediately.
3.
Flush all water lines thoroughly.
4.
Turn the unit OFF.
5.
Close the main shut-off valve from the dental water supply.
C. Inspecting the power cord, water lines, filter and handpiece
• Periodically check and inspect the power cord, water lines,
filter and handpiece for damage, wear or clogging.
• Check connectors at both ends of the cord to make sure they
are fully seated.
D. Inspecting the scaler insert O-ring
• Inspect the rubber O-ring for wear and/or damage. O-rings
will wear over time due to repeated sterilization. When the
O-ring is worn and/or damaged, leakage will occur between
the handpiece and the scaler insert.
• Roll the worn or damaged O-ring over the laminate stack off
the scaler insert, and roll a new O-ring onto the scaler insert
until seated in the groove on the colored plastic grip.
E. Changing the fuse
WARNING:
Replace fuses as marked. Replace the fuse with the
exact fuse type and rating to avoid risk of fire.

P/N: 03821-20
For 230/240 VAC 5 x 20 mm T-Type 0.8 Amp, 250V
P/N: 03321-16
• The fuse compartment is located immediately below the power
cord receptacle on the unit. Open the compartment with a
small screw driver (Fig. 9).
• Inspect the fuse (Fig.10). A good fuse is shown on the left of
Fig. 10, a blown fuse is shown on the right.
• Replace the fuse when necessary, and close compartment until
a click is heard.
