About 50% lighter than Stainless steel ball. Less centrifugal force upon the Retainer Ring.
About 25% harder than Stainless steel ball. Higher tolerance for scarring and deformation. This provides for a smoother rotation, which results in quietness, accuracy, and longer life.

Why is the Clean Head system Needed?When the foot pedal/rheostat is released and air supply is terminated, the bur in a handpiece will spin to a stop (not instantaneously).The turbine rotation under no air supplygenerates negative pressure (vacuum) and drawsforeign matter (fluid, debris) upwards into handpiece head.
Benefits of the Clean Head System Distributes such foreign matter away from the head of the handpiece.
Reduces post-operative contaminants in a handpiece and extends turbine and cartridge life.

Basic NL9000 Manual Maintenance
1. Remove bur from the NL9000
2. Run under warm water and clean softly with a toothbrush.
3. Attach proper nozzle to PANA spray can (this nozzle came in the package with your handpiece).
4. With nozzle attached insert into the rear of the NL9000 and spray for approximately 2-3 seconds or spray until lubrication comes out of the head.
5. Purge the NL9000 of excess spray either via an air station or by returning to the operatory and placing the handpiece back on its coupler.
6. Bag and Autoclave.

Seating and Removing the Bur
Seating the Bur Place the bur into the chuck. Press the push button and insert the bur into the chuck until it is secure.
Make sure that the bur is secure bypushing and pulling the bur. This can also increase the chucking power.
Removing the Bur Press the push-button firmly and remove the bur.
Make certain the bur has stopped rotating before attempting to remove.

Changing the O-Rings
Over a period of time it is possible for water to leak from the coupler joint. If this occurs replace the o-rings as a complete set.
Simple Steps Remove the handpiece from the coupling, loosen and remove the taper ring.
Push out the worn O-ring with your thumb. Insert new O-ring in the O-ring groove.
Securely tighten the taper ring.

If fiber optic light is less intense debris may be blocking the glass rod.
Simply wipe clean the Cellular Glass optic face with alcohol-immersed cotton swab
Do not use any abrasive as it may damage the cellular glass rod
