RE D BEFORE YOU ST RT
The handpiece and tip are water cooled 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, 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, gums or skin, it will
cause burns due the friction of the vibration. The tip does not get hot but the ultrasonic vibration will burn if it makes
contact with soft tissue. 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 / skin. Engler Engineering Corporation is not
responsible for any damage caused by improper use of this device or its accessories.
When using a water bottle, it must be kept pumped to at least 30 PSI. The pressure relief valve (if equipped) 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. The bottle should be maintained at ½ to ¾ full. Always use distilled
water.
It is recommended to remove the tip and clean / disinfect the handpiece after every use to prevent the spread of germs,
bacteria and disease.
Handpieces, tips, prophy angles, rubber cups, straight handpieces, burrs, and water filters, are normal wear and tear
items. In order to achieve optimal performance they should be replaced regularly.
The power switch is on the left side of the unit.

INTRODUCTION
Thank you for purchasing the Engler Piezo-Mate Scaler Polisher combination.
The design of the Piezo-Mate 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 internal circuit board, providing a very durable
and reliable unit.
The dental scaler utilizes an ultrasonic principle of operation. The internal circuitry converts ordinary line
voltage to an operating frequency of approximately 30,000 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 0.00 in. (25. 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 setting.

INST LL TION INSTRUCTIONS
IMPORT NT: This device must be connected to a clean, filtered, water supply, capable of delivering 30 to
60 psi (2.0 to .2 kg/cm2) of water input pressure. This unit comes with an In-Line water filter (P/N: 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 60 psi, we recommend you install a water pressure regulator on the supply line to
your scaler.
CONNECTING WATER SUPPLY:
We strongly recommend that a manual shut off valve
be placed prior to 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 (2 cm)
water line, a male quick disconnect fitting, a water
filter and a coupling body.
The water line must be connected to the white fitting
located on the back of the device before a
connection is made to the water source. To connect
the water line, slide the white (male) insert into the
coupling body until the metal latch locks it in place
making a clicking sound. The water line can now be
connected to your water source.
We suggest that you use one of the four methods as
shown on the next two pages.
301 Male quick disconnect
** Please note, male quick disconnect is supplied as
a standard item with all Engler scalers.
PLE SE REMEMBER
It is recommended that you disconnect the device from the water supply when
it is not in operation.
Engler Engineering Corporation will assume no liability for damages due to not
following recommendations in the Engler manuals.

CONNECTING WATER SUPPLY (cont.)
PLEASE NOTE: Minerals and foreign particles in the water may cause a buildup or blockage of
internal hoses and parts.
The water filter supplied with this device should be opened and inspected on a regular basis.
Engler suggests that the filter disc and O-ring be changed out at least twice per year. See WATER
FILTER CLEANING INSTRUCTIONS.
CONNECTING THE FOOT SWITCH:
To connect the footswitch to the unit, insert the male quick disconnect into the female quick
disconnect at the rear of the device and then tighten the securing nut by turning it clockwise.
CONNECTING POWER SUPPLY:
First plug the power cord into the unit and then plug the male end of the power cord into a
grounded power outlet. DO NOT remove or bypass the ground pin from the power cord of this
device. Doing so will void the warranty.
IMPORTANT: Your Piezo-Mate has been equipped with a universal switching power supply and will
automatically adjust the input voltage. It will not require any adjustments in this regard. See
technical data for specifications.
Do not alter the scaling tip. The tip is shaped to deliver the optimal vibrating power and frequency.
Deforming the tip in any way will cause the handpiece to get hot, degrade vibration power and void
the warranty.

SC LER OPER TING INSTRUCTIONS
Initial procedures at the start of every day:
1. The power switch is located on the left side of the unit. Switch it ON.
2. Make sure the water is open (counter-clockwise) and flowing to the device. Rotate the Selector
Switch to the “SCALER” position, the red LED indicator should light up, showing that you have power
to the unit.
3. Adjust the power control knob to the minimum power setting fully counter-clockwise. The digital
readout will read 1.
. Install handpiece and tip. Use the tip wrench to gently tighten the tip.
5. With handpiece and 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 press the footswitch until water comes out in a stream. This should take no more
than 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.
6. Always keep the power control at the lowest setting and the water control at 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, high
power settings require high water flow rates and conversely low power requires low water flow rates.
7. The scaler is now ready for use.
8. Do not alter the scaling tip. The tip is shaped to deliver the optimal vibrating power and frequency.
Deforming the tip in any way will cause the handpiece to get hot, degrade vibration power and void
the warranty.
9. An anti fatigue mat is recommended to prevent the handpiece from contacting the floor should the
handpiece get dropped. Piezo handpieces work with a crystal which vibrates when energized,
transmitting energy to the tip. Dropping the handpiece could break the crystal. A dropped handpiece
is not covered by the warranty.
Page 11 of 35

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.
Engler Engineering Corporation will not be liable for damage due to improper use of this device. Do not use
this device if the water temperature is too hot.
Call Engler Engineering Corporation technical support if further help is needed.
ULTR SONIC SC LING PROCEDURES
1. Before placing tip into patient’s mouth, activate the scaler 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 unwanted contact.
3. Place the tip into the patient’s mouth and press the footswitch to activate the scaler.
. Bring the tip lightly up 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: Pressure on the tip is not necessary to remove calculus or tartar. Enamel on the teeth
may be damaged or removed if using excessive pressure. It can also 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 will likely damage
the tooth and may change the shape of the tip, which in-turn, changes the frequency. The normal power
setting for most procedures should be LOW range. Since every operator has a different technique and
some patient’s are more sensitive than others, the power may be adjusted to satisfy specific requirements.
The use of a face mask is recommended when operating the scaler, to avoid inhalation of bacterially
contaminated aerosol (water mist) by the operator.
Only individuals properly trained in modern dental cleaning techniques
should be allowed to perform dental procedures.
Improper use of dental equipment can permanently and severely harm a
patient's teeth.
This manual does not attempt to teach dentistry.
Do not use this equipment without proper training.

following the manufacturer’s instructions and recommendations. Do not autoclave over 270
degrees F or more than twenty (20) minutes..
It is recommended to remove tips daily for sterilization. The tip may “weld” itself in the handpiece if
left in for weeks on end.
Chassis:
The chassis should be cleaned at the end of every operating day with a chemical sterilization
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.
SCALER HANDPIECE, FOOTSWITCH AND POWER CABLES:
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:
1. Remove tip, and ultrasonic handpiece- sterilize these items as listed above.
2. Clean the outer surface of the handpiece and its cable with an antiseptic soap, rinse off with
water and sterilize with a chemical sterilization solution.
Note: If any chemicals are allowed to get into the handpiece it must be flushed out with
clean water.
3. Place cleaned tip and into handpiece for next patient.
. The footswitch and power cables should be cleaned periodically by spraying a mist of
sterilization or cleaning solution on the cables. It should remain on the cables for the length
of time recommended by the manufacturer. Wipe the surface with a damp cloth and dry the
cables completely.

lock collar clockwise.
2. Slide the straight handpiece down over the top of the micromotor.
3. Line up the notch of the prophy angle with the aligning pin on the straight handpiece, and then push the
shaft of the prophy angle into the chuck of the straight handpiece.
. Rotate the lock ring clockwise, until it clicks and locks the prophy angle in place.
5. Place a disposable rubber-polishing cup on the end of the prophy angle by pushing / snapping it on. The
prophy angle is now secured and ready for operation.
6. Rotate the selector knob on the front of unit to either forward or reverse operation.
NOTE 1: When using the polisher the green led indicator should be on.
NOTE 2: High speed will damage the gears in the prophy angle, splatter the polishing compound and
overheat the teeth, possibly burning them. Always start at the lowest setting, then increase speed as
necessary.
SAFETY INFORMATION:
Never turn the lock ring while the handpiece is in operation.
1. Never reverse the direction of the micromotor while it is in operation. Damage to the unit may occur.
2. Take care not to drop the micromotor, handpiece, or prophy angle on the floor or other hard surface.
3. Do not lock or run the micromotor / straight handpiece assembly without a prophy angle, cutting disc,
contra angle, or test shaft installed, doing so could damage the straight handpiece and / or micromotor.
. Never oil the micromotor.

POLISHER OPER TION
1. Dampen the rubber cup and place a small amount of polishing paste onto it.
2. Rotate the POWER control to the minimum setting in the Prophy Range.
3. Press the footswitch and the rubber cup will begin to rotate. The speed of rotation may be adjusted to
your desired level by re-adjusting the POWER control.
. To keep the paste from flying off the cup, maintain a low speed and bring the cup up to the tooth before
depressing the footswitch. Then gently rotate the spinning cup against the tooth.
Caution: It is very easy to overheat and cause permanent damage the teeth. Use the lowest
speeds possible with minimal pressure when polishing.
IMPORT NT: The prophy angle is only rated for up to 5000 RPM - therefore, in order to prevent
premature failure of the bearings and gears, keep the unit set in the prophy range whenever the
prophy angle is attached to the straight handpiece.
5. High-speed settings can overheat the tooth being polished and throw the polishing paste off of
the rubber cup. Always start with a lower speed and then adjust to a higher speed as required.
6. Place the end of the angle into the patient's mouth and gently apply the rubber cup to the
surface of the tooth with a circular motion. Do not allow the rubber cup to remain stationary on
one area for an extended period of time.

LUBRICATION:
1. The spray nozzle oiling method is optional but highly recommended because it cleans as well as
lubricates. It forces lubricant into the smallest spaces and forces dirt out. The alternate method
is to place 1 drop of approved oil in the chuck hole. Do not lubricate the handpiece while it is on
the micromotor.
2. Lubrication of the straight handpiece is required at least once a day when used. Preferably by the end of
the day.
3. Make sure that the straight handpiece is in the unlocked position prior to lubricating.
. Install the E-Type nozzle by pushing it into the top of the spray can. Insert the E-Type nozzle
into the bottom of the handpiece (where the micromotor goes). Holding the two together tightly,
with can in the upright position, push spray button for 2 to 3 seconds.
