Preface
About the KRUUSE-SP1 Scaler/Polisher Comb Unit
The KRUUSE-SP1 is CE 0434 certified in compliance with the applicable requirements of the
Council Directive 93/42/EEC. The reviewing council also classifies the KRUUSE-SP1 in
accordance with EN60601-1 and EN60601-1-2 safety requirements.
How it works
The KRUUSE-SP1 consists of two parts: The main electronic system and the scaling hand piece.
The main electronic system utilizes two closed loops. One loop provides automatic tuning to
match the resonance of the insert. The other loop will control the tip stroke based on various
working conditions.
The scaling hand piece utilizes a pulsing magnetic field. This magnetic field is applied to a
metal “stack” which flexes and moves an installed scaling tip (insert) approximately 25,000
cycles per second in an elliptical pattern based on the amount of power used. Thus, more power
results in greater tip displacement, which allows for more robust scaling. However, the
vibrating metal stack generates heat and requires adequate amounts of fluid to cool the hand
piece and tissues during treatment.
When the two parts of the KRUUSE-SP1 are placed together, the properties of the main unit and
scaling hand piece enable the KRUUSE-SP1 to “power away” the heaviest calculus deposits. In
addition, tips may be rotated 360 degrees within the hand piece to relieve cord tension and
alignment. As a result, the KRUUSE-SP1 provides maximum comfort to the patient and ease of
use to the operator.
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

- 6 -
CAUTION：Since the scaling tip (insert) 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 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.
Section II: Contraindications and Warnings
Do not use the KRUUSE-SP1 for amalgam restorative dental procedures.
Do not use the KRUUSE-SP1 if the patient or operator is wearing a pacemaker.
Do not immerse the KRUUSE-SP1 in water or liquid. If the KRUUSE-SP1 has water
damage, return the machine to Bonart for servicing.
Do not modify the KRUUSE-SP1. Modifications will invalidate the warranty on the
machine as well as invalidate safety codes and endanger the patient and operator.
Section III: Precautions
3-A: Precautions for all Ultrasonic Scaler Units and Systems
Ensure sufficient water flow to the scaler tip during use to cool the hand piece and insert.
Take precaution as all ultrasonic scalers produce aerosols that may transmit contagious
diseases.
Keep the unit away from intense heat. Excessive heat may damage the electronic
components.
Switch the water valve off when the KRUUSE-SP1 is not in use.
Avoid treating patients with pacemakers due to the magnetic field produced by the
KRUUSE-SP1.
The magnetic field may cause monitoring devices to malfunction and provide inaccurate
readings.
3-B: Precautions for Ultrasonic Prophylaxis Procedures
Scaling tips (inserts) will wear with use. Inserts with 2mm of wear will lose approximately
50% of their scaling efficiency. In general, it is recommended that inserts be discarded and
replaced after 2mm of wear to maintain optimal efficiency and avoid breakage.
Avoid direct contact of inserts with the patient’s lips, cheeks and tongue.
Do not reuse scaling tips (inserts) that are damaged, bent, or reshaped. Discard
immediately.

- 9 -
Use the long axis of the scaling tip (insert) to wipe accretions from the tooth. Do not gouge
the tooth with the tip.
3-C: Precautions for hand-piece
In order for the system’s hand-piece to function consistently and effectively, Accumulated
air pressure from the handle (or hand-piece) must be released every 10 to 15 minutes on
every procedure by doing the following steps:
1. Put the insert into the hand-piece and make sure it is fully seated.
2. Hold the hand-piece vertically with the insert tip on top; depress the foot Switch (control).
3. Let the water spray out for a minute or so, then start scaling procedure.
Section IV: Infection Control
4-A: General Infection Control Recommendations:
As with all dental procedures, use standard protective equipment such as face masks, eyewear, face
shields, gloves and protective gowns.
To ensure safety to the operator and patient, carefully follow the Infection Control Procedures
detailed in this section.
4-B: Water Supply Recommendations
All dental water supply systems should conform to applicable Centers for Disease Control and
Prevention (CDC) and the American Dental Association (ADA) standards. These standards should
apply to flushing, chemical flushing, and general infection control procedures.
4-C: Cleaning and Sterilization:
Hand piece
Prior to cleaning, remove the insert from the hand piece. Next, drain any water left in the
hand piece to clear the hand piece of any residue accumulated during treatment. Then, clean
the surface of the hand piece with antiseptic soap or solution and rinse thoroughly with water.
Afterwards, wipe or spray a chemical disinfectant on the hand piece. Please try to use a
nonabrasive disinfectant to avoid damaging the hand piece.

- 10 -
After disinfecting the hand piece, a sterile insert may be re-inserted into the hand piece in
preparation for the next patient.
At the end of the day, remove the insert from the hand piece and scrub both, the hand piece and
cable, with antiseptic soap. Rinse thoroughly with water.
NOTE：Cleaning the hand piece after every patient is advised.
WARNING：Do not dip the hand piece and extension cable directly into sterilization fluid.
Doing so will cause the KRUUSE-SP1 to malfunction.
WARNING：Do not leave the disinfectant on the surface of the hand piece and extension
cable any longer than instructed by the manufacturer of the disinfectant.
Insert
Saliva, blood, and other debris will leave a residue on the insert after each use. Therefore, it is
necessary to clean inserts after each use. Cleaning can be done manually by scrubbing the
insert with a brush, water, and detergent. Be sure to rinse thoroughly after scrubbing. Let
the insert dry. Then, place the insert in a bag and autoclave at 275 ℉(135℃) for 15 minutes
(or as recommended by the manufacturer of your sterilization unit) to sterilize the insert.
Bio-indicators or chemical indicators for ensuring the efficiency of the sterilization cycle are
recommended.
NOTE：Routine spore testing will determine the sterile conditions of your office.
NOTE：The Sterilization Assurance Level (SAL) of steam autoclave should be 10-6
(According to ISO 13683:Sterilization of health Care products)
WARNING：High room temperature conditions, improper dilutions, or extended
immersion time in chemical sterilizers can result in damage to the plastic
and other materials of the insert/tips.
CAUTION：The use of a dry heat oven, incompatible chemical vapor type sterilizers or
quaternary ammonium compounds must be avoided as damage can result
to the plastic and elastomeric materials.
Main Unit
