Please take the following in account before using the NSK E-TYPE handpiece;
• To connect the motor and the handpiece,
align the positioning marks of the motor and
the handpiece, and insert straightly. To
disconnect, hold the front part of the motor
and the back part of the handpiece, and pull
out straightly. Do not connect or disconnect
the handpiece until the motor has
completely stopped.
• To mount the bur, insert it into the chuck
and turn the Bur Lock Ring in the direction
of the mark [C] until it clicks and the Black
Dots align (*See the picture below). To
remove the bur, turn the Bur Lock Ring in the
direction of mark [O] until it clicks. Most
common mistake is that people start working
in the middle position, between the lock and
unlock. Never do that!
• Never use bent, off-centered or damaged burs. Excessive loads generated by defective burs
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 2,8mm up may cause a short life to the
handpiece chuck.
• 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
JURA Engraving system:
What makes the JURA Artgraver special beyond the air compressor free feature? It's the
handpiece. The single handpiece can be quickly modified by switching out the piston to
allow for a wide variety of engraving styles from light bulino work to heavy engraving in
hard metals like steel and titanium.
