RE D BEFORE YOU ST RT
The scaler handpiece, ultrasonic transducer (stack), and tip are water cooled devices and must always have adequate
water flow to function properly. The amount of water delivered to the handpiece must be regulated according to the
power level. If the power level is increased, the amount of water must also be increased. Not having enough water flow
through the scaling handpiece may permanently damage the handpiece, will cause the handpiece to get hot, degrade
transducer life and void the warranty. For more information, please turn to the Scaler Operating Instructions page.
When active, ultrasonic tips vibrate at over a million cycles per minute, if it touches soft tissue or skin it will cause burns
due the friction of the vibration. The tip is not normally hot but the ultrasonic vibration will burn you if you touch it, this is
due to the friction between the skin and the vibrating tip. This is normal for all ultrasonic scalers. Never let the scaling
tip touch soft tissue or skin, Engler Engineering Corporation is not responsible for any damage caused by improper use
of this device and / or its accessories.
When using a water bottle, it must be kept pumped to at least 30 PSI. The pressure release valve will slightly move out
showing the yellow interior when pressure builds up. As water is used the pressure will decrease and the bottle must be
pumped to keep adequate pressure.
Never twist or bend your ultrasonic stack. Be careful not to twist or bend the stack when inserting or removing it from
the handpiece. Pull the stack straight out to remove it. Always make sure the stack is properly aligned when inserted
into the handpiece. There is a white dot in the handpiece and a hole in the stack, they must be aligned during insertion.
Bending the stack or inserting it incorrectly into the handpiece may irreparably damage the stack and degrade it’s ability
to vibrate. Improper insertion of the stack may also damage the handpiece as well as cause it to get hot. Damage
caused by bending or forcing the stack into the handpiece is not covered by the warranty. A stack removal tool is
available from Engler Engineering Corporation, it is part number 47903.
Do not alter the scaling tip. The tip is shaped to deliver the optimum vibrating power level and keep its optimum
frequency. Deforming the tip in any way will cause the handpiece to get hot, degrade vibration power and void the
warranty.
Dropping the handpiece with the stack and tip may alter or damage your tip and stack causing the handpiece to get hot,
degrade power / vibration and void your warranty.
Remove the tip and nosecone from the stack and clean / disinfect after every use. Stacks, tips, prophy angles, rubber
cups, straight handpieces, burrs, and water filters, are normal wear and tear items. In order to achieve optimum
performance they should be replaced regularly.
The ultrasonic stack normally last six months to a year. To maintain optimum performance, replace every six months to
a year or as needed. Do not leave the ultrasonic stack inside the ultrasonic handpiece for long periods of time. The
O-rings may dry out and make it difficult to remove the stack.
Lubricate the stack O-rings with an appropriate lubricant for your practice, for example mineral oil or petroleum jelly is
appropriate for most practices. A stack removal tool and a maintenance kit are available from Engler Engineering
Corporation.
The water regulator has multiple turns. Turn the water regulator knob counterclockwise to open and clockwise to close.
The amount of turns required is dependent on the supplied water pressure.
The power switch is on the left side of the unit.
Turn off the unit and disconnect the waterline when not in use.

INTRODUCTION
Thank you for purchasing the Engler Sonus II Ultrasonic Scaler.
The design of the Sonus II scaler circuitry uses integrated computer technology along with our Time Remote
Feedback Circuitry. This combination produces a powerful and potent tool against periodontal disease. A
reinforced solid aluminum chassis surrounds the circuit board, providing a very durable and reliable unit.
The dental scaler utilizes an ultrasonic principle of operation. The circuitry converts ordinary line voltage to an
operating frequency of approximately 18,000 Hz. This frequency is then amplified and delivered to the scaling
tip. As a result, the tip vibrates at this ultrasonic frequency with an amplitude of 0.001 to 0.004 in. (25.4 um to
102 um).
In designing our unique Engler tips, water flows internally through the tip as it vibrates. As the bubbles in the
lavage are bactericidal, the energy released collapses and destroys the bacterial cell walls. The water flowing
internally through the tip, effectively cools the area and assists in removing any debris from the operative site.
This device is equipped with a digital readout that provides an indication of the power that the unit is set at.
PLEASE READ VERY CAREFULLY

INST LL TION INSTRUCTIONS
Before installing or operating your new Sonus II, carefully read and follow all of the instructions.
IMPORT NT: This device must be connected to a clean, filtered, water supply, capable of delivering 30 to 0
PSI., 0 to 4.2 kg/cm2) of water input pressure. This unit comes with an In Line Water Filter
(part # A52030). When kept clean and free of foreign matter, it will assist in proper water flow to the unit. If the
water pressure in your office is above 0 psi, we recommend you install a water pressure regulator on the
supply line to your scaler.
CONNECTING W TER SUPPLY:
We strongly recommend that a manual shut off valve
be placed ahead of the Female Quick Disconnect, so
that the water can be completely shut-off, and line
pressure relieved, when the unit is not in use.
This device comes equipped with an 8 foot (244 cm)
water line, a Male Quick Disconnect fitting, a Water
Filter and a Coupling Body (which connects the water
line to the back of the unit).
The water line must be connected to the white fitting
located on the back of the unit before a connection is
made to the water source. To connect the water line.
Slide the white (male) insert into the coupling body (at
the back of the unit) until the metal latch locks it in
place making a clicking sound. The water line can
now be connected to your water source.
To connect to a water supply, we suggest using one
of the four options shown on the next two pages.

SC LER OPER TING INSTRUCTIONS
Initial procedures at the start of every day:
1. Make sure the power switch is ON, it is located on the left side of the unit.
2. Adjust the power control knob to the minimum power setting fully counter-clockwise. The digital display
will read 1.
3. With no insert in the handpiece (no tip installed), set the water control to its maximum setting by
rotating it counterclockwise, (knob will rotate up to 3 and a half turns for maximum water) hold the
handpiece over a sink and depress the footswitch until water comes out in a stream. This should take
20 - 30 seconds. This step is done to insure proper operation of the delay cavitation feature by
removing air that may be trapped in the water lines.
Warning: DO NOT run the handpiece for more than 30 seconds without water
flow. Doing so will permanently damage the handpiece and void the warranty.
NOTE : The O-rings on the insert should be lubricated weekly with a thin film of petroleum jelly
to keep the O-rings on the insert from sticking in the handpiece.
4. Place the insert in the handpiece, push the white nosecone onto the handpiece and then install a sterile
tip into the nosecone. Rotate the nosecone clockwise to tighten the tip. Tighten firmly by hand.
IMPORT NT: It is important that you DO NOT over-tighten the tips, as this may damage the
handpiece, stack, and / or tip and void the warranty.
5. IMPORT NT: If you find that tightening the nosecone by hand is not successful, you may lightly
tighten the nosecone with the tip wrench. Since the tip wrench is designed to remove the tips, it is
important that you DO NOT over-tighten the tips with the tip wrench, as this may damage the stack, tip,
and / or the handpiece and void your warranty.
. Always keep the power control at the lowest setting and the water control to a level where you have a
fine mist at the tip. Higher power settings will result in hotter water.
NOTE: Tips sent from our facility are not sterilized.
IMPORT NT: Keep in mind that higher power levels tend to heat the out-flowing water. Temperature
control can be achieved by balancing the power with water flow volume. Thus, higher power settings
require high water flow rates and conversely lower power requires low water flow rates.
7. The scaler is now ready for use.
IMPORT NT: Operating this device with hot water may cause damage to gums, lips and tongue. If the
handpiece begins to get warm, stop and check water temperature. If it is hot, make sure that the power
is at the lowest setting and the water is set at a high enough setting to provide a lukewarm mist. Do not
use this device if the water temperature is too hot.
Engler Engineering Corporation will not be liable for damage due to improper use of this device.
10

ULTR SONIC SC LING PROCEDURES
1. Before placing tip into patient’s mouth, activate the scaler handpiece over a sink by depressing the
footswitch. A fine mist, with the temperature between cool to lukewarm to the touch is
recommended. This should be accomplished with minimal power and proper water flow.
2. It is recommended that when a tip is placed into a patient’s mouth, the lips, cheek and tongue
be retracted to prevent contact.
3. Place the tip into the patient’s mouth and depress the footswitch to activate the scaler.
4. Bring the tip to the tooth and gently move it over the surface of the tooth with an erasing motion.
5. A saliva ejector or HVE is recommended.
IMPORT NT: Do not leave the vibrating tip in one place as it can cause serious damage to the tooth or
surrounding tissues. Engler Engineering Corporation will not be liable for damage due to improper
use of this device.
Note: We have designed the this device with a feature called Delayed Cavitation. This function purges the tip
of water after releasing the footswitch to prevent bacteria from entering the tip.
IMPORT NT: Excessive pressure on the tip is not necessary to remove calculus or tartar. Enamel on the teeth
may be damaged or removed if excessive pressure is used. The enamel may be damaged if the scaling tip is
left to rest in one spot for even a few seconds. Using the tip, as a pry to remove calculus or tartar is strongly
discouraged as it can damage the teeth and incidentally change the shape of the tip, altering it's performance.
The normal power setting for most procedures should be near mid-range. Since every operator has a different
technique, the power may be adjusted to satisfy specific requirements. Ultrasonic scaling procedures are not
intended for soft tissue.
C UTION: Contact with Soft Tissue Will Cause Burns. Engler Engineering Corporation will not be liable
for damage or injury due to improper use of this device.

solution. This procedure could be done by spraying a fine mist of sterilization solution on the unit, allowing it to
remain on the chassis for the length of time recommended by the manufacturer. The surface should be wiped
with a clean damp cloth or as suggested by the chemiclave manufacturer. Dry completely.
IMPORT NT: In using any chemical sterilization solution please follow the manufacturer’s suggested
procedures.
H NDPIECE, FOOTSWITCH ND POWER C BLES:
After each procedure, or at least once a day, it is suggested that the handpiece and its cable be thoroughly
cleaned and sterilized. The recommended procedure is as follows:
Note: If any chemicals are allowed to get into the handpiece, it must be flushed out with clean water.
1. Remove tip, and nosecone - sterilize these items as listed above.
2. Clean the outer surface of the handpiece and its cable with an antiseptic soap, rinse with water and
sterilize with a chemical sterilization solution.
3. Place sterile tip and nosecone into handpiece for next patient.
