CAUTION
Rotate the bur to check for vibrations, noise, or temperature (heat) being emitted. Should the Handpiece function abnormally
at this time, stop using it immediately and contact your Authorized NSK Dealer. (Refer to "6. Checking the Handpiece Before
Each Use")
Do not disassemble or alter the handpiece except as recommended by NSK in this Operation Manual.
Do not allow any impact on to the product. Do not drop the product.
Operators and all others in the area must wear eye protection, a mask, and gloves when operating the Handpiece.
–1
Operate the Handpiece at speeds under the maximum rotation speed of 35,000min .
When using a bur with a large cutting blade (4mm or larger in diameter), use it at as low a rotation speed as possible.
Do not use burs with problems listed below as the bur may break, seize up or disengage from the chuck.
– Bent, deformed, worn, rusted, broken, deficient bur.
– Bur which is cracked on the edge or axis.
– Non-ISO (EN ISO) standard, or tampered bur.
Always keep the bur shank clean. Debris in the chuck could cause poor bur concentricity or low chuck retention force.
Always insert the bur all the way into the chuck. If insertion is insufficient, premature failure of the handpiece head bearings,
or accidental release of the bur, may occur.
