Caution
General Cautions:
• This handpiece is intended for use by dental professionals only.
• Do not use this for the treatment in dental surgery.
• NSK handpieces should not be rebuilt.
• Should the handpiece function abnormally, cease operation immediately
and return the handpiece to the dealer for repair.
Cautions on Operation:
• Do not turn the bur lock ring while the handpiece is rotating.
• Do not rotate the motor when the bur lock ring is at OPEN position, or a
bur is not mounted in the chuck. It may cause the motor/handpiece
disconnection or sudden heat generation.
• This handpiece is designed for (dental) treatment and precision technical
use. Longtime excavation with high torque with thick burs such as 4mm
or greater in diameter may cause a short life to the bur, hard-to-pull-off
bur or bur drop-off, which results in injury.
• Do not allow any impact on the shank. Do not drop the handpiece.
• Check the vibration, noise and overheating outside the patient's oral
cavity before use. If any abnormalities are found, stop using immediately
and contact your dealer.
• Make sure that the bur is securely locked in the chuck before each use.
Improper mounting of the bur could cause the bur to spin out during
rotation and endanger anyone in the vicinity.
• Do not use bent, off-centered, deformed, damaged, nor non-ISO
standard burs.
• Use clean bur. Dirt on the shank may lodge in the chuck in time and
could cause poor concentricity of the bur or poor chucking power.
• Be sure to check on the device and the components periodically.
• Make sure that the product is normal by rotating it with attention to
backlash, vibration, noise, heat generation, when you use it again after a
long time.
• Do not wipe with, or clean or immerse in, high acid water or sterilizing
solutions.
Caution
Do not connect or disconnect the handpiece until the motor has
completely stopped.
1. Specifications
To connect the motor and the handpiece, align the positioning marks of

Caution
• Never clean the handpiece (EX-5B, EX-6B, EX-6D) in boiling water.
• Always place the handpiece in the center or upper shelf of the
chamber, as the local temperature at the bottom of chamber could
rise beyond the set value.
Caution
• Be sure to hold the handpiece firmly to prevent the handpiece from
slipping out by the spray pressure when lubricating.
• Supply lubricant until it comes out of the handpiece nose (for
approx. 2 seconds).
• Keep the PANA-SPRAY Plus can upright.
Tips for safe use and for maximum service life
• Never use bent, off-centered or damaged burs. Excessive loads
generated by defective burs rotating at 40,000min-1(rpm) will quickly
damage ball bearings.
• This handpiece is designed for (dental) treatment and precision
technical use. Longtime excavation with high torque with thick burs
such as 4mm or greater in diameter may cause a short life to the
bur, hard-to-pull-off bur or bur drop-off, which results in injury.
• Always insert a bur all the way into chuck. This will prevent “BUR-
WALK-OUT”, and/or damage to the ball bearing.
• Never operate Straight Nosecone without a bur or bur blank
securely in place, or bur lock ring at different positions.
• Make sure if the Os of the bur lock ring line up after fixing the bur.
Rotating the bur in an improper position may cause heat generation,
which results in burns.
(1) Cleaning
Wipe clean the handpiece sheath with alcohol-dipped soft tissue or
cotton. Never clean the handpiece in chemicals, with wire brushes, or
in ultrasonic cleaners.
(2) Sterilization
Steam autoclave is recommended.

autoclaving.
PANA-SPRAY Plus
Push E-type spray nozzle attachment over the PANA-SPRAY Plus
nozzle until it firmly seats.
Shake the can 3-4 times to well mix lubricant and propellant.
Insert the E-type spray nozzle in the rear of the handpiece and spray for
approximately 2-3 seconds until the oil comes out of the handpiece
head or nose.
