INDICATIONS FOR USE:
This air-turbine high-speed handpiece is intended to be used
for general dentistry.
CONTRAINDICATIONS:
Do not use this handpiece within the oral cavity when a soft
tissue wound is present. Air pressure may force septic
materials into these tissues.
WARNINGS:
•This product is intended for use by dental professionals only.
•It is the responsibility of the Dental Healthcare Professional (DHCP)
to understand the intended uses of this product, the health of each
patient, the dental procedures being undertaken and industry and
governmental agency recommendations, requirements, and
regulations for safe practice of dentistry.
•Before operating handpiece, carefully read and follow these
instructions and save them for future reference.
•Handpieces should be heat-sterilized between patients to prevent
cross-contamination which could result in serious illness or even
death from infectious organisms such as HIV (the virus that causes
AIDS) or hepatitis B.
•Do not cut with the handpiece unless you are sure the bur is secure. Do
not extend the bur outward from the handpiece head. A loose or extend-
ed bur could eject from the head or break and cause personal injury.
•Sterilize handpiece prior to first use.
•Midwest turbines should not be rebuilt. Replacing bearings only could
result in unexpected failure and patient injury due to different wear
factors of new vs. old components.

Checking Handpiece Hose
Make sure all tubing supplying the handpiece hose is properly
connected within the dental unit. Be sure the air and water are
delivered to the handpiece as shown in the illustration below.
Air Requirements
The handpiece delivers designed speed and torque when operated
with clean, filtered, moisture-free air at the recommended operating
pressure of 40 psi (2.7 Atm.) for 180S, 360S, 540S series and
42 psi (2.9 Atm.) for 181S, 361S, 541S series. Air pressure
should be measured at the handpiece end of the hose.
Have your dealer or serviceman use an analyzer gauge. Connect
gauge to hose, then handpiece to gauge. Fully depress foot control
and run the handpiece. Adjust drive air pressure to 40 or 42 p.s.i.
(see requirements above) as indicated on analyzer gauge. Remove
gauge and connect handpiece to hose.

Installation, continued

To disconnect, pull and twist handpiece while securely holding
coupler and hose nut. Coupler remains installed on the hose.
Water Spray Requirements
The Midwest Stylus uses delivery unit chip air to deliver fine mist water
spray. The recommended operating pressure for chip air is 25 psi for
180S, 181S, 360S, 361S series and 30 psi for 540S, 541S series. The
recommended operating pressure for water is 12 psi for 180S, 181S,
360S, 361S series and 6 psi for 540S, 541S series. If you get a
stream of water instead of a fine mist, adjust water and chip air
pressure to achieve desired spray mist.
Water Supply Recommendations
• It is highly recommended that all dental water supply systems
conform to applicable CDC (Centers for Disease Control and
Prevention) and ADA (American Dental Association) standards, and
that all recommendations be followed in terms of flushing, chemical
flushing and general infection control procedures.
• As a medical device, this product must be installed in accordance with
applicable local, regional and national regulations including guide-
lines for water quality.
DENTSPLY recommends the following steps between each patient
use to prevent cross-contamination and to ensure continued
trouble-free operation of your Stylus handpiece.
IMPORTANT: Use only Midwest®Plus™ Aerosol Spray as
recommended by DENTSPLY to maintain your handpiece.
See Parts section for ordering information.

Cleaning and Maintenance

Scrub and Rinse
1. Disconnect handpiece from coupler.
2. Push button to remove bur.
3. Scrub and rinse handpiece under warm tap water with a soft
brush or sponge. While scrubbing and rinsing, it is best
to keep the handpiece in the upright position (see
illustration at below).
4. Make sure fiber optic light port near head of handpiece is
scrubbed well. Once a week or as needed, gently rub an
alcohol-soaked cotton swab against both ends of the fiber
optic element to remove debris.
DENTSPLY Professional also
recommends lightly lubricating
the coupler O-rings with Midwest
Plus Handpiece Lubricant.
Lubricate and Expel Using
Midwest Plus™ Aerosol Spray

nozzle fully into handpiece (without a bur). Cover head of handpiece
with Midwest spray guard or paper towel. Spray for no more than one
(1) second. If excess debris appears, spray again for one (1) second.
2. Run handpiece (without a bur) until it reaches normal
speed, or until all excess lubricant is expelled (a minimum of
20 seconds). Expel in operatory or using Midwest Air Station. Wipe
off any excess lubricant on outside of handpiece with a dry gauze
pad or paper towel.
3. On a weekly basis
or if button gets stiff,
spray Midwest Plus™
Aerosol Spray into
chuck for one second.
NOTES:
• A KaVo MULTIflex lubricating nozzle will conveniently fit
onto Midwest Plus™Aerosol Spray.
• If a coupler is needed for use with Midwest Air Station,
order Midwest Maintenance Coupler, REF 380090.
(For 180S, 360S, 540S series.)
Cleaning Water Spray Holes
Run the cleaning wire (supplied with your handpiece) back and
forth in the water spray holes and in the air spray holes to loosen
and remove any mineral build-up at spray surface.

Insert handpiece (without a bur) into sterilization bag and load into
autoclave. (DENTSPLY Professional recommends using sterilization
bags with at least one paper side.) Handpieces should be processed
in the autoclave for 15 minutes at a sterilization temperature of
135ºC/275ºF.
For cassette chamber saturated steam devices, handpieces
should be processed unbagged for 3.5 minutes at a
sterilization temperature of 135ºC/275ºF.
Keep handpiece in bag until ready to use in the operatory.
Insert the coupler into the handpiece until it “clicks” into place.
Check for secure connection by tugging the handpiece. To operate
the handpiece, simply depress the foot control on your dental unit.
Note: The Midwest Stylus uses delivery unit chip air to deliver fine
mist water spray. If you get a stream of water instead of a fine mist,
just increase the “chip air” or “coolant air” on the delivery unit until
the desired fine mist spray is achieved (see page 5 for recommended
settings).
