Warnings
Important!
The KRUUSE-SP2 should be operated solely by qualified personnel (trained
doctors, dentist, and hygienists, etc.).
Patients with pacemakers should not be treated with the KRUUSE-SP2
Do not immerse the KRUUSE-SP2 in water!
If the patient or operator is pregnant, consult a physician prior to performing
dental scaling for safety purposes.
The KRUUSE-SP2 requires a shieldedAC power cord.
Plug the power cord into a well-grounded outlet.
Attention to users with cardiac pacemakers!
Patients with pacemakers should avoid treatment with the KRUUSE-SP2. Studies have
shown that electronic appliances including razors, hair dryers, microwave ovens, TV
receptors, and other medical equipment, such as the KRUUSE-SP2, may interfere with the
performance of pacemakers.
For more information on this subject, please refer to the following articles:

Article 2, pp. 515-1075
"Electromagnetic Radiation Interference with Cardiac Pacemaker", U. S. Department of
Health, Education and Welfare

Dental Association, Vol. 91, No. 6, pp. 1224-1229

Please Read Before Operating:
Make sure the device is connected to a grounded outlet. Failure to
meet this requirement may severely damage the user and device.
Place the device on a flat and stable surface. Placing the device
on a tilted or unstable surface may degrade performance or damage
the device.
Do not modify the device. Modifications to the device will violate
safety codes and invalidate the warranty while endangering the
patient and operator.
Do not place heavy objects on top of the power cord and keep the
power cord away from intense heat.
Unplug the device and call Bonart for service and instructions if
you observe any abnormalities while operating the device.

Preface
About the KRUUSE-SP2 Scaler/Polisher Combo Unit
The KRUUSE-SP2 is CE 0434 certified in compliance with the applicable requirements of the
Council Directive 93/42/EEC. The reviewing council also classifies the KRUUSE-SP2 in
accordance with EN60601-1 and EN60601-1-2 safety requirements.
How it works
The KRUUSE-SP2 Piezoelectric Ultrasonic Scaler generates ultrasonic waves in the hand piece
to vibrate the tip, which allows the KRUUSE-SP2 to remove calculus and tartar easily. These
ultrasonic waves are created by 4 ceramic piezoelectric plates subjected to high frequency
alternating currents.
The piezoelectric transducer operates at a frequency of 29khz with minimal noise and heat, and
efficiently reduces the amount of cooling water required during treatment. This
electric-mechanical feature provides greater efficiency than traditional magnetostrictive systems.
Features:
Scaler and polisher in one system
Automatic phase lock and power control
Automatic feedback control
Micro-motor speed control of 2,000 to 30,000 RPMS
CAUTION：Since the scaling tip is made of stainless steel, avoid direct contact with teeth.
Direct contact will cause damage to teeth enamel. For optimum performance, we suggest
practicing on a model or aluminum plates to become more familiar with the scaling tips before
performing on patients.

SECTION I: INDICATIONS FOR USE
Ultrasonic scaling procedures:
Removal of calculus and plaque during dental prophylaxis.
General supra and sub-gingival scaling applications.
Periodontal debridement for all types of periodontal diseases.
Endodontic procedures.
Polishing procedures:
For removal of calculus and plaque during dental polishing.
All general supra and subgingival polishing applications.
Periodontal debridement for all types of periodontal diseases.
Endodontic procedures with optional bur tools.
SECTION II: CONTRAINDICATIONS AND WARNINGS
Do not use the KRUUSE-SP2 for amalgam restorative dental procedures.
Do not use the KRUUSE-SP2 if the patient or operator is wearing a pacemaker.
Do not immerse the KRUUSE-SP2 in water or liquid. If the KRUUSE-SP2 has water
damage, return the machine to Bonart for servicing.
Do not modify the KRUUSE-SP2. Modifications will invalidate the warranty on the
machine, violate safety codes, and endanger the patient and operator.
SECTION III: PRECAUTIONS
Precautions for the KRUUSE-SP2 and all Ultrasonic Scaler Systems
Ensure that an adequate amount of water flows to the piezo tip during use in order to cool
the hand piece and tip.
Take precaution to prevent transmission of contagious diseases as all ultrasonic scalers
produce aerosols.
Use tips manufactured by Bonart for optimal performance.
Keep the KRUUSE-SP2 away from heat sources to prevent overheating and damaging of
electrical components.
Ensure that the water valve is closed when the KRUUSE-SP2 is not in use.
Avoid treating patients with pacemakers due to the magnetic field produced by the
KRUUSE-SP2.

Precautions for Ultrasonic Prophylaxis Procedures
Discard and replace piezo tips as needed. Scaling tips wear out with use and should be
replaced after 2mm of wear (approximately 3 to 4 months) to maintain optimal performance
Discard and replace piezo tips that are bent, damaged, or reshaped. Do not reuse deformed tips
BONART piezo tips are made of stainless steel. Avoid direct contact with teeth to prevent
damage to the enamel. We strongly advise practicing on models and aluminum plates prior to
operating on a live subject with the KRUUSE-SP2.
Avoid direct contact of piezo tips with the subject’s lips, cheeks, and tongue.
Wipe accretions from the tooth using the long axis of the scaler tip. DO NOT gouge the tooth

Section IV: Infection Control
General Infection Control:
Always use standard personal protective equipment such as facemasks, eyewear, face shields,
gloves, and protective gowns.
In addition to using protective equipment, ensure that your water supply system conforms to
applicable Centers for Disease Control and Prevention (CDC) and American Dental Association
(ADA) standards, and that all required flushing, chemical flushing, and general infection control
procedures are followed.
To further protect against infection, using distilled or purified water is recommended.
Cleaning and Sterilization:
All sterilization procedures must be followed in accordance to the EN ISO17664 standards.
In order to avoid bacterial or viral infections, always clean and sterilize the following components
after each treatment:
1. Hand piece
2. Tips
3. Metal Wrench
4. Micro-motor
5. Straight hand piece (Straight nose cone)(optional accessory)
6. Prophy head (unless disposable)(optional accessory)
The hand piece, tips, wrench, straight handpiece and prophy head can be autoclaved and can
withstand a maximum temperature of 135℃or (275℉) for a maximum of 3 minutes. After
completing the sterilization cycle, air-dry for about 20-30 minutes before reusing.
WARNING: Do not use any other method of sterilization (dry heat, radiation, ethylene oxide,
gas, low-temperature plasma, etc.)
NOTE：The SterilizationAssurance Level (SAL) of steam autoclave should be 10-6 (According
to ISO 13683:Sterilization of health Care products)
NOTE: Prior to cleaning and sterilizing your KRUUSE-SP2 unit, always remember to turn
off the device by using the power switch and to disconnect the power plug from the outlet.
