1. Grasp the swivel in front of the bearing assembly 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 swivel 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 swivel.
5. Using the wrench as shown, tighten the swivel to the tubing coupler until snug. Be sure to turn the tubing coupler, not the swivel. DO NOT OVER TIGHTEN.
6. Connect handpiece to swivel until it clicks.
Note: This joint loosens over time, resulting in a loss of power. Check for tightness periodically.
430 K:
1. Slide tubing coupler until the end of the ISO connector is exposed; hold in hand as shown
with smaller fingers securing the tubing.
2. Align handpiece tubes into the ISO connector holes.
3. While applying slight pressure to hold handpiece tubes in the connector holes, slide coupler
forward and engage threads. Continue threading coupler clockwise until hand tight against
the handpiece.
Handpiece Operation
Air and Water Adjustment
1. Air Pressure –
NOTICE
To prevent premature damage to the turbine, do not exceed 34 psi when using a HiFlo swivel.
Use an air pressure gauge, StarDental Part #262591 for 4/6-Line: set pressure to:
34-42 psi - 430 SWL
30-32 psi - 430 SW
30-32 psi - 430 K.
If a gauge is not available, set pressure at delivery head allowing 1 psi pressure loss for every foot of tubing.
(See Specifications for recommended operational pressure.)
For example, if you are using the 430 K that you want to operate at 32 psi and you are using either 5 feet or 12 feet of tubing, then the pressure should
be set at the delivery head to compensate for the air pressure losses.
2. Water Pressure – Adjust water volume at the delivery head to obtain a satisfactory spray mist.
3. Non-Star 6-pin Fiber Optic System:
If the handpiece is connected to a non-StarDental 6-pin fiber optic (F.O.) system, consult your operator's manual of F.O. system for correct voltage.
Non-StarDental F.O. systems must have a rated amperage output between 1.5 Amps dc and greater than .73 Amps dc at 3.1 Vdc. Use StarDental Part #
262962 bulb for non-StarDental F.O. systems that meet these requirements. Adjust the voltage per instructions with the 3.1 Vdc bulb.
If the non-StarDental 6-pin F.O. system has a rated amperage output of at least 1.5 Amps dc at 3.3 VDC, then the StarDental Part #262522 bulb may be
used. Adjust the voltage per instructions with the 3.3 VDC bulb.
Use standard length concentric diamond and carbide burs with .0628" 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 Burs. StarDental
autochuck turbines have the following bur requirements:
Use only burs with hardened, tempered steel shanks or carbide shanks. Every StarDental Bur maintains

• Warranty
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 have bent or 'soft' (non-heat treated) shanks.
® handpiece is a conventional Autochuck Bur Changing System
1. Insert bur into autochuck until resistance is felt.
2. Depress autochuck end cap button and continue to feed-in bur until it clicks and stops.
Type: High speed with a replaceable autochuck
3. Release end cap button. Now, apply light inward force to the dental bur. This will help set the chucking mechanism for initial start up. (Always tug on bur

after it has been installed to confirm that it is secured).

1. To remove, grasp handpiece firmly so your thumb touches the end cap and push until a slight 'click'

3. Release end cap.
Sterilizable up to 135°C
CAUTION
Never depress the autochuck end cap button or rest the end cap against any part of the
oral anatomy during handpiece operation. Depressing the end cap while a bur is rotating can activate
the chuck mechanism and result in end cap heat-up and/or loss of bur retention.
SAFETY
INSTRUCTIONS
To minimize risk of serious injury:
• Always insert bur the full length of the chuck. If you attempt to extend it from the chuck, the bur may dislodge during use and possibly injure you or

place
To minimize risk of injury or damage to handpiece or auto chuck:
• Replace turbine when handpiece does not run at full speed or runs noisily.
• Use only recommended burs. An improperly clamped or bent bur, usually indicated by sudden high-pitched sound or increased vibration during
use, may dislodge injuring you or your patient.
• Follow these safety instructions:
- Confirm bur is secure by tugging on it after it is loaded
- Verify concentric rotation by operating handpiece outside oral cavity. Do not use if it does not run concentrically or runs with excessive noise.
- Do not operate handpiece without an installed bur.
- Always use burs with overall length of less than 24mm. Shank length must be at least 7.3 mm. This includes most short shank burs. (see Handpiece
Operation)
- When using autochuck, never depress end cap while bur is rotating.

For maximum turbine life do not exceed recommended pressure.
Note: Lubricate handpiece daily with DentaLube II , StarDental Part #262539, and prior to each sterilization
procedure.
Tubing
1. Disconnect handpiece.
2. Assemble the conical red tip applicator, StarDental Part #202954, into the DentaLube II bottle cap.
3. Find drive air tube at rear of handpiece and place three drops of DentaLube II.
(See illustrations for more detail).
Note: Never operate handpiece without bur in place.
4. With bur in place connect handpiece to tubing, operate for 20 seconds to expel excess lubricant.

NOTICE
This turbine uses a sophisticated ceramic bearing design and, therefore, requires no lubrication. To ensure the life of, and to prevent
damage to, this turbine - do not lubricate it. If it gets lubricated even once, it MUST then continue to be lubricated for the rest of its life.
Cleaning & Sterilization
It is the responsibility of the user to use only FDA compliant sterilizing equipment and accessories that are
CAUTION
capable of meeting the manufacturers recommendations below.
Do not exceed 135°C
CAUTION
To prevent damage to the bur, use an autoclavable bur block.
Do not use:
• dry heat sterilizer
• chemical disinfectors
• surface wipes
• sterilizer bags
containing disinfectants
Limits On Reprocessing Repeated processing has minimal effect on this handpiece. End of life is normally determined by wear and
damage due to use.
INSTRUCTIONS
WARNING Clean and sterilize handpieces and burs as soon as practical before first use and after each patient.
Containment and transportation: It is recommended that handpieces are reprocessed as soon as is reasonably practical following use.
Preparation for cleaning: Remove handpiece from swivel. No further disassembly is required.
Cleaning - Automated: Washer-disinfectors are not recommended.
Cleaning - Manual: Cleaning Handpieces:
Internal Surface
• After each use, clean the diamond bur by running it against a wet diamond cleaning stone.
• To mechanically clean, the diamond bur should be held in a solution of either enzymatic
presoak, Sparkl® Dental Instrument Cleaner StarDental Part# 205472, or water.
• Rinse the bur thoroughly and allow it to dry, then Sterilize – See Sterilization.
Lubrication: Lubricate - For Lubricated Handpieces ONLY - See 'Lubrication' instruction section
Disinfection:
Use steam sterilization exclusively for complete sterility as outlined below.
Maintenance: Use Junk-Out High Speed Chuck Cleaner Kit (263790) once a week prior to sterilization to ensure
optimum working condition of the chuck. Instructions for cleaning the chuck are included in the Junk-Out kit.
See Turbine Replacement section of this manual for additional information.
Handpiece should be routinely maintained, checked for corrosion, worn parts, etc. and should be replaced
on an as needed basis.
Inspection & function testing: See Handpiece Operation or Troubleshooting sections of this manual.
Packaging: Single: A standard sterilization packaging material must be used. Ensure that the pack is large enough to
contain the handpiece without stressing the seals.
In sets: Handpieces may be loaded into dedicated instrument trays or general purpose sterilization trays.
Ensure that cutting edges are protected and do not exceed the tray manufacturer's limit per tray. Wrap the
trays using appropriate packaging materials and methods.
Wrapped Instrument Gravity Type Autoclave:
Sterilization:
• Minimum of 15 minutes at 132° C
• Minimum of 30 minutes at 121° C
