with a diameter that exceeds the specified values may result in a bur run out and cause the bur to bend or break.
øa Diamond Bur : ø2mm or less
Carbide Bur : ø1mm or less
Be careful of overheating when using some
types of carbide bur, as the coolant water (in
“water jet” mode) cannot reach the bur tip
because of the shape of the tip.

2) Remove the bur.
3) Disconnect the handpiece from the motor.
8-2 Cleaning
Manual Cleaning (External Surface)
1) Remove dirt and debris on the handpiece surface using a brush under running water (at 38°C or less).
Do not use a wire brush.
2) Wipe off the moisture on the surface using absorbent cloth.
CAUTION
•If water comes inside the handpiece, blow air into the rear of the handpiece using an air syringe and remove the remaining water.

16
Automatic Cleaning (External and Internal Surfaces)
Use a thermo-disinfector in accordance with ISO 15883 (EN ISO 15883).
Refer to the thermo-disinfector manual.
CAUTION
•After washing with thermo-disinfector and prior to lubrication, dry the product until all internal moisture is thoroughly removed. Thermo-
disinfector moisture remaining inside the product could reduce the effect of lubrication and could cause corrosion inside of the product.

CAUTION
•Hold the spray can upright.
•Be sure to hold the handpiece firmly to prevent slipping out of hand by the spray pressure when lubricating.
•Supply lubricant until it comes out of the handpiece head.
•If you wish to expel excessive oil from inside of the handpiece, rotate the handpiece for approx.15 seconds without a bur. During the rotation,
do not depress the push button inadvertently, especially when using absorbent cloth to prevent oil from scattering. Depressing the push button
during rotation may cause a failure to attach a bur.
