TECHNICAL DESCRIPTION
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
READ THIS MANUAL FULLY BEFORE ATTEMPTING TO
INSTALL OR USE THE AQUACUT QUATTRO MACHINE.
The AQUACUT QUATTRO fluid abrasion unit is a twin dispenser system. This allows the user to
select either Cutting or Polishing Powders instantly. The Dosing Chambers can be loaded with
either 29 or 53 micron aluminium oxide for tooth reduction and fine granular sodium
bicarbonate for tooth cleaning and polishing.
The AQUACUT QUATTRO is entirely pneumatic in operation and therefore the only supply
needed to the machine is a clean, dry air supply of between 5 bar, (72 psi) and 7.5 bar,
(109 psi) to ISO 8571.1 class 1.4.1. This can be the dental practice’s existing air supply
system, an independent compressor or bottled air/nitrogen.
Secondary gas supply is not recommended at this time.
It is essential that a high performance water removing filter and a shut-off valve are fitted in the
supply line, (see section on recommended accessories).
The incoming air to the AQUACUT QUATTRO is internally regulated to 7.5 bar, (109 psi) max,
for the pneumatic control system with and supply to the powder cartridge chambers to 5 bar,
(72 psi).
The flow of clean dry air to the handpiece is initiated by depressing the foot switch roller down
to the first index position. (Felt as 1st resistance point to downward movement).
The flow of clean air and fluid to the handpiece is initiated by depressing the foot switch roller
down to the second index position. (Felt as 2nd resistance point to downward movement).
The flow of powder and fluid to the handpiece is initiated by depressing the foot switch roller
fully down. Residual powder in the line to the handpiece is vented into a filtered exhaust
collector inside the machine when the roller is allowed to return to the upper position.
The foot pedal actuates a purpose built pinch valve block within the Aquacut Quattro, which
in turn controls the flow of the abrasive laden air.
The pinch valve tubes are easily changed on a routine basis in a few minutes without the use
of special tools.
The abrasive powders are supplied in sealed, colour-coded single use cartridges that are
calibrated to supply the correct range of flow rates for each powder.
The powder cartridges can be changed at any time by simply switching the Aquacut Quattro
off, removing the lid from the dosing chamber, lifting out the powder cartridge and sliding in a
new one after removing the two yellow sealing tabs. Replace the dosing chamber lid, switch
on the supply and the unit is ready for use again.
When in use, the dosing chamber lids are held securely in place automatically and cannot be
inadvertently removed while under pressure.
To undo a lid, the Aquacut Quattro must be switched off; this automatically vents the internal
pressure from the complete unit. Residual powders in the lines are filtered into the exhaust
collector.
Complete depressurisation of the machine takes about 20-30 seconds.
The Aquacut Quattro fluid runs in a parallel path to the handpiece tip, where it combines with
the cutting medium. The fluid is drawn up the twin supply tube to the tip by the venturi effect
of the particle air stream. At the tip the fluid is ejected as a conical spray over the outside of the
particle stream and acts to contain the cutting medium within the cutting area. In this way the
amount of airborne Aluminium Powder/Sodium Bicarbonate is significantly reduced.

There are four controls available to the user, the Air/2nd supply selector; Cut/Polish Powder
selector; Powder volume and Cutting/Polishing speed.
The air pressure, (Speed), at the handpiece can be adjusted over a variable range of 1 – 3.
The Powder volume can be adjusted over a variable range of 1 – 5.
The handpiece with fitted tungsten carbide tipped nozzles is easily removed from the air line
for cleaning, sterilizing or replacement.
WARNING: WHEN OPERATING THE AQUACUT QUATTRO, IT IS ESSENTIAL THAT
A FILTERED HIGH SPEED INTRA-ORAL EVACUATION UNIT IS USED AT ALL TIMES.
IT IS ALSO RECOMMENDED THAT A FILTERED EXTRA-ORAL EVACUATOR IS ALSO
USED.

INDICATIONS FOR USE AND WARNINGS
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
INDICATIONS FOR USE
Preparation for Pit and Fissure Sealants
Removal of Composites for Restoration
Cavity Preparation
Cleaning, Polishing and Stain removal
Etching
WARNINGS
Do not turn on the air supply until you have read the complete manual, particularly the section
headed ‘Removing and Refitting the Dosing chamber lids’ (see page 21), and have made sure
that both Dosing Chamber Lids, (item 14 & 16), are correctly and fully engaged.
All powders supplied by Velopex are sterile until opened and containers are not reusable.
The foot pedal, (item 11), must be sited in such a place that it will not be operated by accident
as this will cause a high pressure stream of abrasive powder to be emitted from the cutting
nozzle, (item 31), in an uncontrolled and therefore dangerous manner.
Use only original Medivance consumable products, (powders etc), as other makes may
damage or alter the performance of the Aquacut Quattro and make the machine dangerous.
Always ensure safety goggles and respiratory masks are worn by everyone in the area when
setting up or using this equipment..
Always ensure the handpiece is under control and the nozzle is pointing in a safe direction.
Handpieces MUST be sterilised before first use and between patient treatments.
Disposable feedline and tips are for one time use only. Always use a new feedline and tip
with each patient.
