.
Problem: IMPROPER SPRAY
Cause:
Clogged filters, tubes or water ports
Correction:
Inspect water filter in delivery head.

Manual Bur Changing System
Maximum
24.0 mm
OVERALL LENGTH
Minimum
10.8 mm
Shank Length
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.
Handpiece Operation
WARNING:
Use burs with an overall length of less than 24 mm and a shank length of at least 10.8 mm.
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
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
burs that do not run concentrically or produce excessive noise.
3. Never operate handpiece without a bur installed.
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.
PLEASE OBSERVE SAFETY RULES
Cleaning and Lubricating
The
Concentrix III
and
Concentrix IV
Handpieces’ bearings are lubricated and sealed to keep the dirt out, therefore never
clean ultrasonically or immerse in solvent that would dilute the lubricant.
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
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.
LUBRICATING the Turbine
Note:
Lubricate handpiece
prior
to each autoclave sterilization procedure. The use of the
grease syringe is no longer necessary. Use
DentaLube II
as described in this section.
After each patient, flush with air and water by running handpiece for 20 seconds
.
1. Disconnect handpiece from tubing.
2. Insert the red tip applicator,
StarDental
Part #202954, into the
DentaLube II
bottle cap.
3. Identify drive air tube at rear of handpiece and place three drops of
DentaLube II, StarDental
Part #262539. (See illustration for more detail).
4. With bur in place connect handpiece to tubing, operate for 20 seconds to
expel excess lubricant.
5. Disconnect handpiece from tubing.
6. Clean all external surfaces using a small toothbrush with isopropyl alcohol.
7. Remove Bur.
8. Sterilize - See Sterilization
9. Remove handpiece from sterilizer after drying cycle end and allow to cool in bag.
Troubleshooting
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.
5. Using the set of tools
StarDental
Part #263568, Insert the
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)
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.

Air and Water Adjustment
1. For 4-Line: using an air pressure gauge,
StarDental
Part #262591, set pressure to 30 psi (2.1 kg/cm
2
).
For 2/3-Line: if a gauge is available, set pressure to 30 psi (2.1 kg/cm
2
); if a gauge is not available, set pressure at
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
2
)
or
for 12 feet (3.65 m.) tubing: set control at 42 psi. (2.95 kgs/cm
2
)
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.

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.
Note:
An unwrapped handpiece or bur needs to be used immediately or sterility is not maintained.
Do not exceed the sterilizer manufacturer’s guidelines for load capacity.
CAUTION:
Use steam sterilization exclusively for complete sterility. Never dry heat sterilize, ultrasonically
clean, or expose handpiece, bur or swivel to chemical disinfection or cold sterilization by:
• Immersion techniques or Surgical milk
• Surface wipes, Hand soaps, or Detergents
• Surface sprays
• Sterilization bags containing disinfectants
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.
- Rinse the bur thoroughly and allow it to dry.
- Sterilize – See Sterilization
Cleaning Carbide Burs:
- After each use, presoak the bur in solution of either enzymatic presoak or water.
- Rinse the bur thoroughly and allow it to dry.
- The bur may be cleaned with an autoclavable bur brush to remove any resistant debris from the bur.
- Sterilize – See Sterilization
