WARNING: This product is intended for use by dental professionals only. Before operating
handpiece, carefully read and follow these instructions and save them for future reference.
Observe all cautions and warnings, including:
• 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.
• It is the responsibility of the Dental Healthcare Professional to determine the appropriate use
of this product and to understand the health of each patient, the dental procedures being
undertaken and industry and governmental agency regulations, recommendations and
requirements for safe practice of dentistry.
Precautions
• 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 extended bur could eject from the head or break
and cause personal injury.
• 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.
• 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.
Adverse Reactions
None Known.

Checking Handpiece Hose
Make sure all tubings supplying the handpiece hose are properly connected within the dental unit.
Be sure the air and water are delivered to the handpiece as shown in the illustration below.

The handpiece delivers designed speed and torque when operated with clean, filtered, moisture-free air at the
recommended operating pressure of 30 p.s.i. (2.0 Atm.). Air pressure should be measured at the handpiece
end of the hose.
Water Supply Recommendations
It is highly recommended that all dental water supply systems conform to applicable CDC (Centers for Disease

Installation, Maintenance and Operation Instructions
Scrub and Rinse
Scrub and rinse under warm tap water. Make sure fiber optic bundles are scrubbed well.
Expel Cleaner and Dry
Run handpiece on Midwest Handpiece Air Station (REF 380800) or other air source for 30 seconds or until
handpiece reaches normal speed, and all excess cleaner is expelled. Handpieces with bur tool chucking system
(Tradition REF 750045/750044 or Quiet-air REF 730014/464004) should always be covered with a Spray Guard
or have a bur installed before running. Dry thoroughly.
Lubricate and Expel
1. Lubricate by placing 3 drops of Midwest Plus Handpiece Lubricant (REF 380130) into drive air tube (shorter
of two larger tubes).
2. Run handpiece for 30 seconds or until it reaches normal speed, and until all excess lubricant is expelled.
Wipe off any excess lubricant on outside of handpiece with a dry gauze pad or tissue.
2 Maintenance Using
Midwest Plus ™ Aerosol Spray
Scrub and Rinse
Remove bur. Scrub and rinse under warm tap water. Make sure fiber optic bundles are scrubbed well.
Clean, Lubricate and Expel
Clean and lubricate with one quick spray of Midwest Plus™ Aerosol Spray (REF 380080) using the Midwest
Backend Attachment nozzle (REF 380086) into the drive air tube of the handpiece. The drive air tube is the
shorter of the two larger tubes and is gold on many handpieces. Run the handpiece on Midwest Handpiece Air
Station or other air source for 30 seconds or until normal speed is reached, and all excess spray is expelled.
This handpiece with a bur type chucking system should always be covered with a Midwest Spray Guard or have
a bur installed before running. Dry thoroughly.
Bag • Autoclave
Insert handpiece into sterilization bag and load into autoclave. (DENTSPLY recommends using sterilization bags
with at least one paper side.) Handpieces should be processed in an autoclave set for a minimum of 15
minutes at sterilization temperature (132ºC/270ºF).
For cassette chamber saturated steam devices, handpieces should be processed unbagged for a
minimum of 3.5 minutes at sterilization temperature (135ºC/275ºF).
Keep handpiece in bag until ready to use in the operatory. No relubrication is necessary.
Other Maintenance
Ultrasonically Clean Handpiece Head
As needed, only if sluggishness occurs:
1. Place handpiece head down in beaker of Midwest Plus Handpiece Cleaner.
2. Ultrasonically clean for 10 minutes.
3. Continue from Scrub and Rinse, above.
4. In the lubricating step, also place 1 drop of Midwest Plus Handpiece Lubricant (REF 380130) in chuck
(for Push Button and Latch models: REF 790045 / 790044 / 780045 / 780044 / 780014 / 484004).
Cleaning Water Spray Tube

Never operate the handpiece under the following conditions:
1. In the presence of a soft tissue wound.

Tradition handpieces accept regular friction grip (FG) burs and short shank (SS) burs.
To use bur wrench: Insert square pin of bur wrench through
the handpiece's head cap until it engages the square socket in
the chuck. Fit the two wrench pins into the matching slots in
the head cap. Turn the wrench counterclockwise to open the
chuck, clockwise to tighten.
To install a bur: Open chuck, insert bur all the way into the
chuck. Tighten chuck with bur wrench.
Make sure bur is secure before operating handpiece.
Always use bur wrench to tighten chuck.
To remove bur: Insert the bur wrench into the back of the handpiece head. Rotate the wrench 1/2 turn
counterclockwise, then remove bur.
Note: The water spray will adequately cover bur and diamond cutting instruments up to .906 inches
(23 mm) long.
