135°C
Sterilizable up to 135°C
Handpiece Installation
Note: Filter air and water supplies. Soften and deionize water. Be sure filters operate efficiently. To ensure efficient spray
pattern, it is recommended to use a 12 micron water fliter.
1.
Grasp the handpiece in front of the fixed connection
between the thumb and index finger as shown.
2.
Slide tubing coupler until the end of the tubing
connector is exposed; hold in hand as shown with
fingers securing the tubing.
3.
Align and insert handpiece fixed connection tubes into
the tubing connector holes.
4.
While applying slight pressure to hold fittings in the
connector holes, slide coupler forward and engage
threads. Continue threading coupler clockwise until
hand tight against the handpiece.
Air and Water Adjustment
For 4-Line: using an air pressure gauge, StarDental Part #262591, set pressure to 30 psi (2.1 kg/cm
1.
For 2/3-Line: if a gauge is available, set pressure to 30 psi (2.1 kg/cm
delivery head allowing 1 psi (.0703 kg/cm
2
) pressure loss for every foot (30 cms) of tubing. Example:
for 5 feet (1.52 m.) tubing: set control at 35 psi. (2.46 kgs/cm
or
for 12 feet (3.65 m.) tubing: set control at 42 psi. (2.95 kgs/cm
Note: For maximum turbine life, do not exceed recommended pressure.
2. Water Pressure – Adjust water volume at the delivery head to obtain a satisfactory spray mist.
Handpiece Operation
Use standard length concentric diamond and carbide burs with 1.6mm nominal diameter friction grip shanks designed for
high speed handpieces. Every StarDental Diamond Bur meets specifications below for recommended lengths. Contact your
dealer for a complete list of StarDental Diamond and/or Carbide Burs.
Star Dental Manual turbines have the following bur requirements:
Use only burs with hardened, tempered steel shanks or carbide shanks. Every StarDental
Bur maintains required hardness. Before use, verify concentric rotation by operating
handpiece outside the oral cavity in a safe place.
Note: Do not use burs that produce excessive noise or do not run concentrically. Do
not use burs that are modified, eccentrically designed, or are bent or 'soft' (non-
heat treated) shanks.
WARNING: Use burs with an overall length of less than 24 mm and a shank length of at least 10.8 mm.
Manual Turbine Bur Changing System
1. Pull handle back on manual bur tool, StarDental
Part #203108, and slide open end of tool onto
IV
®
square nut as shown; release spring loaded handle
and seat shaft of tool into the opening in the rear of
turbine housing.
2. To unlock chuck, turn manual bur tool handle
counterclockwise.
3. After inserting a 1.6 mm diameter friction grip bur
fully into chuck, turn handle of tool clockwise to
tighten chuck.
4. Disengage tool and tug on bur to verify that it is completely engaged and holding securely. If chuck does not hold bur
securely, clean or replace chuck.
CAUTION: Be careful to keep bur tool aligned with handpiece. If tool is side-loaded while engaged in chuck, tool may
be damaged.
REMOVAL of Bur from the Manual Chuck
1. Use manual bur tool and turn counterclockwise one full turn, 360° rotation.
®
2. Pull bur straight out.
Safety Rules
PLEASE OBSERVE SAFETY RULES
1.
Always tug on bur after chuck is loaded to confirm that the bur is secured.
2.
Before use, verify concentric rotation by operating the handpiece outside of the oral cavity in a safe place. Do not use
• Rear Seal Replacement
burs that do not run concentrically or produce excessive noise.
• Replacement Part Numbers
3.
Never operate handpiece without a bur installed.
• Warranty
4.
Use burs with an overall length of less than 24 mm. Shank length must be at least 10.8 mm.
5.
Use only recommended burs to prevent damage to handpiece cartridge and/or chuck, and in some cases to prevent burs
from improper or incorrect placement. An improperly clamped bur may dislodge during use, causing injury to you or
your patient. A sudden, high-pitched sound or increased vibration while handpiece is operating alerts the operator to

the possibility that the chuck is not clamped sufficiently to retain the bur or a bent bur is inserted.
Cleaning and Lubricating
The Concentrix III and Concentrix IV Handpieces' bearings are lubricated and sealed to keep the dirt out, therefore never

Cleaning the Chuck - clean prior to sterilization (after each patient)
Clean the chuck once a day or as required. Remove bur from chuck; place 2 drops
of DentaLube II, StarDental Part #262539, into chucking mechanism. Aerate with
syringe air.

Monthly Cleaning of the Chuck
®
Part #262399
1. Loosen chuck with bur tool; remove bur.
2. Turn bur tool knob counterclockwise until chuck emerges from end cap.
3. Remove bur tool; turn chuck with fingers to free.
4. Clean chuck with alcohol
5. Run paper through 3 slots of chuck; remove debris.
6. Reinstall chuck by reversing steps 1-3.
CLEANING Burs
NOTE: Burs Must Be Cleaned and Sterilized After Each Patient.
Cleaning Diamond Burs:
- After each use, clean the diamond bur by running it against a wet diamond cleaning stone.
- Then, the diamond bur should be cleaned by being held in a solution of either enzymatic presoak or water.
2/3-line Tubing Connector

Sterilization
Handpiece, chuck and burs must be cleaned and sterilized after each patient.
Note: To Prevent Damage To the Bur, Use an Autoclavable Bur Block.
A wrapped handpiece or bur should be steam sterilized at 132° C for a minimum of 10 minutes or at 121° C for a
minimum of 50 minutes. Use paper or plastic bags only. Do not exceed 135° C.
An unwrapped handpiece or bur should be steam sterilized at 132° C for a minimum of 8 minutes or at 121° C for a
minimum of 30 minutes. Do not exceed 135° C.

Troubleshooting
Problem: LACK OF POWER
Cause: Air pressure
Bur
Correction: Verify proper handpiece air pressure. (Refer to Specifications.)
Cause: Crimped tubing
Correction: Straighten the tubing inside and outside delivery head.
Cause: Debris buildup in handpiece
Correction: Clean inside of housing and end cap with cotton swab and alcohol. Before installing turbine and end
cap, lubricate the O-rings with DentaLube II using the soft end of a cotton swab.
Problem: WATER OR AIR LEAKAGE
Cause: Brittle handpiece rear seal
Correction: Refer to Rear Seal Replacement.
Cause: Handpiece not threaded fully onto tubing
Correction: Refer to appropriate Handpiece Installation.
Problem: IMPROPER SPRAY
Cause: Clogged filters, tubes or water ports
Correction: Inspect water filter in delivery head.
Disconnect handpiece. Depress foot control; verify that water exits
tubing. Insert cleaning wire provided, StarDental Part #256719, into spray tube near handpiece head
to clear debris. Remove wire; aerate spray tubes with syringe air.
Turbine & O-Ring Replacement
1.
Remove end cap by unthreading counterclockwise.
2.
Push cartridge out back of handpiece.
3.
Remove o-rings from housing using an explorer.
4.
Clean housing and O-ring grooves using a cotton swab soaked
in isopropyl alcohol. All debris and pieces of O-ring must be
removed from the grooves.
Using the set of tools StarDental Part #263568, Insert the
5.
insertion cap all the way down until it stops as shown. (Detail 1)
6.
Place O-ring inside housing, and guide it to the groove.
Make sure O-ring is past exhaust hole, or the O-ring could be
cut when trying to insert base. (Detail 2)
7.
Insert the base gently until it stops on housing as shown.
(Detail 3 & 4)
Chuck
8.
While holding the base against housing, push on the insertion cap and O-ring
until it is against the base. Pull the base out gently and check the O-ring,
O-ring should be seated in lower groove. Failure to insert O-ring in groove after
two attempts may be the result of debris in groove. Clean groove and follow
steps 5 through 8. (Detail 4 & 5)
9.
Push the tool flush with the lower edge of the upper groove and guide new O-ring as best as possible to the groove.
10. While holding the insertion cap in place, push base gently into housing driving O-ring into groove. (Detail 6)
11. Remove base verify that the O-ring is in the groove, then push insertion cap out. (Detail 7)
12. Install new turbine. Thread end cap on. (Detail 8)
Rear Seal Replacement
Seals wear with repeated use. Once a year or as needed, replace the rear seal in the handpiece: for the 2/3-line handpiece re-
place rear seal with StarDental Part #203103, and for the 4-line handpiece replace rear seal with StarDental Part #202897.
