HANDPIECE INSTALLATION
NOTE: Filter air and water supplies, recommended filtration: 25 microns. Soften and deionize water. Be sure filters operate efficiently.

AIR AND WATER ADJUSTMENT
1. Air Pressure –
NOTICE
To prevent premature damage to the turbine, do not exceed recommended pressure (see Specifications) when
using a W&H/ADEC RA-24 Swivel.
Using an air pressure gauge for 4/6-Line, set pressure to 44-46 psi.
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 40 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.
5 feet tubing 40 psi + 5 psi = 45 psi
12 feet tubing 40 psi + 12 psi = 52 psi
2. Water Pressure –
Adjust water volume and coolant air pressure at the delivery head to obtain a satisfactory spray mist.
HANDPIECE OPERATION
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 the specifications at right for recommended lengths. Contact your dealer
for a complete list of StarDental Diamond Burs. StarDental autochuck turbines have
the following bur requirements: (Fig. 2)
Use only burs with hardened, tempered steel shanks or carbide shanks. Every StarDental
Diamond 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.
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.
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 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.
LUBRICATION - FOR LUBRICATED HANDPIECES ONLY
For maximum turbine life do not exceed recommended pressure.
NOTE: Lubricate handpiece daily with Handpiece Lubricant, StarDental Part #266188, and prior
to each sterilization procedure. (Fig. 4)
1. Disconnect handpiece.
TUBING
2. Shake lubricant can well before using.
COUPLER
3. Thread 430 SWL RA Lubricated Lubricant Tip onto can nozzle.
4. Press handpiece onto 430 SWL RA Lubricated Lubricant Tip until handpiece stops.
5. Place rag around handpiece.
6. Holding firmly, press spray button on can for one second.
FIG. 1
7. Remove handpiece from 430 SWL RA Lubricated Lubricant Tip.
TUBING
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.
LubeFree Handpieces Contain A LubeFree Ceramic Bearing Turbine -
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.

It is the responsibility of the user to use only FDA compliant sterilizing equipment and
accessories that are capable of meeting the manufacturers recommendations below.
Do not exceed 135°C
To prevent damage to the bur, use an autoclavable bur block.
Do not use:
• dry heat sterilizer • cold sterilizers • ultrasonic cleaners
• chemical disinfectors • immersion techniques • surgical milk
• surface wipes • hand soaps • detergents
• sterilizer bags • surface sprays
containing disinfectants
Repeated processing has minimal effect on this handpiece. End of life is normally
determined by wear and damage due to use.
Handpieces and burs must be cleaned and sterilized before first use and after each patient.
It is recommended that handpieces are reprocessed as soon as is reasonably practical
following use.
Remove handpiece from swivel. No further disassembly is required.
Washer-disinfectors are not recommended.
Cleaning Handpieces:
Remove debris from external surfaces using a
FIG. 5 Optical Surface
small brush and isopropyl alcohol. (Fig. 5)
(1 of 2)
Clean internal surfaces of the handpiece at the
swivel 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
Internal Surface
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.
Turbine Lubrication - For Lubricated Handpieces ONLY- See 'Lubrication' instruction
section
Bearing/Ring Assembly Weekly Lubrication:
Lubricate bearing/ring assembly with
DentaLube II, StarDental Part# 262539. Place
RED TIP
three (3) drops as shown. Use a small brush to
APPLICATOR
distribute the lubricant.
FIG. 6
Use steam sterilization exclusively for complete sterility as outlined below.
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.
See Handpiece Operation or Troubleshooting sections of this manual.
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 .
