HANDPIECE INSTALLATION

NOTICE
To prevent premature damage to the turbine, do not exceed recommended pressure when using flex swivel. Snap Aeras 400 Flex handpiece onto 6-pin Flex Swivel. (Fig. 1)

HANDPIECE OPERATION

NOTICE
To prevent premature damage to the turbine, do not exceed 43 psi when using a Flex Swivel.

AIR AND WATER ADJUSTMENT

1. AIR PRESSURE – Use an air pressure gauge, StarDental Part #262591 for 4/6-Line: set pressure to: 38-43 psi – Aeras 400 Flex handpieces, 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 want to operate at 38 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. 5ft. tubing 38 psi + 5 psi = 43 psi or 12 ft tubing 8 psi + 12 psi = 50 psi
2. WATER PRESSURE – Adjust water volume in tandem with chip air volume at the delivery head to obtain satisfactory spray mist.

Use standard length concentric diamond and carbide burs with .0628″ nominal diameter friction grip shanks designed for high speed handpieces .(Fig. 2) 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 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 have bent or ‘soft’ (non-heat treated) shanks.

AUTOCHUCK BUR CHANGING SYSTEM

1. Insert bur into autochuck until resistance is felt. (Fig. 3)
2. Depress autochuck end cap button and continue to feed-in bur until it clicks and stops.
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).
4. To remove, grasp handpiece firmly so your thumb touches the end cap and push until a slight ‘click’ is noticed.
5. Pull bur straight out.
6. Release end cap.

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.

RFID TAG

TO ACTIVATE RFID TAG

1. RFID Tag is passive. Activation and operation of RFID capabilities requires a compatible (EPC GEN2) reader system operating in the 902-928 MHZ band.
2. Pass handpiece within 6 inches of the reader with a sideways orientation as shown to the right (Fig 4).
3. The RFID Tag is programmed from the factory with the handpiece serial number.

SAFETY INSTRUCTIONS

WARNING:
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 your patient.

CAUTION:
TO MINIMIZE RISK OF INJURY OR DAMAGE TO HANDPIECE OR AUTOCHUCK:

• 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 24 mm. 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.

LUBRICATION

FOR LUBRICATED HANDPIECES ONLY

For maximum turbine life do not exceed recommended pressure.

NOTE: Lubricate handpiece daily with Handpiece Lubricant, StarDental Part

264183, and prior to each sterilization procedure. (Fig. 5)

1. Disconnect handpiece.

2. Shake lubricant can well before using.

3. Thread Flex Lubricated Lubricant Tip onto can nozzle.

4. Press handpiece onto Flex Lubricated Lubricant Tip until handpiece stops.

5. Place rag around handpiece.

6. Holding firmly, press spray button on can for one second.

7. Remove handpiece from Flex Lubricated Lubricant Tip.
   NOTE: Never operate handpiece without bur in place.

8. With bur in place connect handpiece to tubing, operate for 20 seconds to expel excess lubricant.

9. Wipe off excess lubricant from handpiece.

NOTICE
LubeFree handpieces contain a LubeFree ceramic bearing turbine. 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.

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:| Handpieces and burs must be cleaned and sterilized before first use and after each patient.
CONTAINMENT & 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: (Fig.6)

Remove debris from external surfaces using a small brush and isopropyl

alcohol. Clean internal surfaces of the handpiece at the swivel OPTICAL SURFACE (1 OF 2)

connection location using a small brush and isopropyl alcohol. Optical surfaces can be cleaned with a cotton swab soaked in isopropyl alcohol. Dry thoroughly. Repeat after each patient.

CLEANING DIAMOND BURS:
•           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.
