BRASSELER USA NL Series User manual

OPERATION MANUAL
High Speed Air Turbine Handpiece
Please read this Operation Manual carefully before use and file for future reference.

Caution
•When operating the handpiece always consider the safety of the patient.
•The handpiece is designed only for dental clinical use.
•Do not attempt to disassemble the handpiece or tamper with the mechanism.
•Check the vibration, noise and overheating outside the patient's oral cavity before use. If any abnormalities are found, stop using
immediately and contact Brasseler USA.
•Should the handpiece function abnormally, cease operation immediately and return the handpiece to Brasseler USA for repair.
•Depressing the push-button while handpiece bur is in rotation will result in OVERHEATING of the handpiece head. Special caution
must be exercised during use to keep cheek tissue AWAY from the push-button of the handpiece. Contact with cheek tissue may
cause the push-button to depress and injury to the patient may occur.
•Do not allow any impact on the sheath. Do not drop the handpiece.
•Do not use bent, damaged, or sub-standard burs. The shank could be bent or broken even within the recommended speed.
•Always keep the bur shank clean. Entry of debris into the chuck could cause bur run-out.
•Do not exceed the speed recommended by the bur manufacturers.
•Do not operate the handpiece without the bur or test-bur
•Remove the handpiece or the bur after the air supply is stopped completely.

Caution on Burs
• Do not use non-standard burs. The ISO standard shank diameter is Ø 1.59 - Ø 1.60 mm.
• Do not use bent, worn, damaged, or non-concentric burs.
• Always use within the bur manufacturer's recommended allowable speed.
• Always use clean burs. Unclean burs may allow debris to build up inside chuck, causing weak bur retention or premature chuck wear.
• Insert the bur all the way into the chuck until it stops with the push-button fully depressed.
• Do not use short shank burs in Standard or Torque head handpiece.
• Use short shank burs in the Mini head handpiece.

Caution on Burs
2. Mounting and Removing the Bur
Mounting
Insert the bur into the chuck. Press the push-button and insert the bur into the chuck
until it is secure. (Fig. 1)
Fig. 2

Caution
Removing
Press the push-button firmly and remove the bur. (Fig. 3)
• Mount / Remove the bur after the air supply is stopped
completely.
• It could be hard to remove the bur after cutting (e.g. removing
the crown). Pull the bur with a pair of pliers while pressing
the push-button.

3. Chuck Cleaning
Perform the cleaning of the chuck once a week for Push Button
Chuck (FG bur).
Chuck Cleaning Method
1) Mount the arrow-head spray nozzle tip into the spray port.
2) Lubricate chuck directly thorough the hole for bur attachment.
Fig.4
Nozzle Tip

Caution
Push the Push Button during the lubrication.
Caution
Do not attempt oil or alcohol rinse it in the water. It may cause malfunction.
3) Lubricate the handpiece. (Refer to Lubrication)
4) After the cleaning, mount the bur and check the griping force for the
chuck. If you feel griping force is weak, stop using it and send it to
Brasseler USA for evaluation.

4. Sterilization
Caution
• Do not heat or cool the handpiece quickly. Rapid change in temperature could break the cellular glass rod give abnormal
strain to other metals. (only for optic handpiece)
• Do not wash, soak, or wipe off the handpiece with/in the oxidation potential solution (strong acid, superacid
solution) or sterilized solution.
Autoclave sterilization is recommended.
Autoclave sterilization required first time you use and after each patient (after lubrication) as noted below.
Autoclave Procedure
1) Scrub dirt and debris from the handpiece, and wipe clean with alcohol-immersed cotton swab or cloth. Do not use a wire brush.
2) Lubricate with spray.
3) Insert into an autoclave pouch. Seal the pouch.
4 )Autoclavable up to a max. 275°F (135°C). ex.) Autoclave for 20 min. at 250°F (121°C) or 15 min. at 270°F (132°C).
5) Keep the handpiece in the autoclave pouch to keep it clean until you use it.

3) Do not exceed the air pressure of 42.7psi (3.0bar). Air pressure readings
must be checked at the coupling joint as shown in Fig. 9.
1) Align the pipe of the coupling and the pipe hole of the hose, and push the
coupling onto the hose. Hold the coupling tightly and fasten the nut of the
hose securely. (Fig. 7)
2) Insert the handpiece firmly onto the coupling until it clicks to engage. (Fig. 8)

Caution
Air Pressure in excess of 42.7psi (3.0bar) could cause fracture of
the bur or premature failure of ball bearings.
Caution
Connect / Disconnect the handpiece after the air supply is
stopped completely.

5c. Clean After Each Patient
Hole
Hole
It is important to clean the holes in the head as follows after each patient and before autoclaving to maintain lasting
CLEAN-HEAD performance. (Fig. 11)
1) Use the cup filler of the dental unit and fill the patient’s paper cup.
2) Brush off the debris at the holes.
3) Immerse half of the head in clean water while the handpiece
is running. (Fig. 12)
4) Run and stop the handpiece in the water 4-5 seconds.
5) Remove the handpiece, while running, from the water. Stop and
wipe dry the handpiece.
6) If debris still does not come off, use the brush supplied, and
clean the holes. (Fig. 13)
7) Lubricate before autoclaving.

• Hold the spray can upright.
• Be sure to hold the handpiece firmly to prevent the handpiece from slipping out of hand by the spray pressure when lubricating.
• Supply lubricant until it comes out of the handpiece head (for approx. 2-3 seconds).
Caution
5d. Lubrication
SPRAYSPRAY
Spray Nozzle Handpiece

Screw in the taper ring tightly. A loose taper ring could result in water and/or air leak.
Caution
5e. Changing O-ring
Change O-rings if there is water in the exhaust line. There is a possibility of water leak
from the coupling joint. Please make sure to change O-rings by the set.
1) Remove the handpiece from the coupling, loosen and remove the taper ring. (Fig. 15)
2) Push out the worn O-ring with your thumb. Insert new O-ring in the O-ring groove. (Fig. 16)
3) Securely tighten the taper ring.
