2.1.3 Do not use the bur which is bended, defect, injured.
2.1.4 Please keep the bur clean. The dirt will stock in the hole of spring of handpiece, result in loosing and
abnormal wear of the chuck.

7
2.1.5 Do not use short bur (mini bur) on standard handpiece, otherwise the bur will drop o󰀨 because of
carelessness.
2.1.6 Do not use long bur on mini handpiece, otherwise the bearing will damage because of overload of

picture 3 picture 4
2.4 Enter the bur into the end, otherwise the bur will drop o󰀨, and lead to unbalance load of the
cartridge and accelerated the damage of the bearing.
2.5 Handpiece and handpiece tube connection
2.5.1 Handpiece and handpiece tube connection(without quick connector): connect the inlet tube, water

9
inlet, turn back tube and atomization tube of handpiece interface to the handpiece tube. To tighten the
thread direction of rotation
2.5.2 Handpiece and handpiece tube connection(with quick connector): connect the inlet tube, water inlet,
turn back tube and atomization tube of quick connector interface to the handpiece tube. Fix the quick
connector with the wrench, To tighten the thread direction of rotation
2.5.3 Installation and use for quick connector.
A) Remove the quick connector, clench the handpiece and quick connector, and pull back
B) Install the quick connector, press the quick connector to the handpiece, check the handpiece before
operating in the patient’s month.
C) Control of atomization: two transferred to the same straight line is the largest, Adjust to the right the
water ow slowly decreases until stop.

10
Water ow reaches the maximum when the two points in the same line
2.6 Cautions
2.6.1 The operator of dental handpiece must be with professional training, and familiar with the relative
usage information.
2.6.2 Gripping part of bur could not be too short, otherwise it will lead to unbalance load of the cartridge
and accelerated the damage of the bearing.

11
2.6.3 Don’t operate the handpiece when there is no bur or standard stick on it, otherwise the head
of chuck will be threw out because of the anti-force, and damage the bearing.
2.6.4 Please don’t press the cover until the handpiece is totally stopped.
2.6.5 Please do the pre-operation inspection outside patients oral before operating. If there is abnormal
phenomenon like loose, vibrating, noisy or fever, please stop it and contact the manufacturer or its
authorized maintenance center.
2.6.6 Damaged handpiece cartridge might probably cause high noisy, and damage the hearing if long-time
use, please replace it timely.
2.6.7 Please use the standard bur, handpiece size is 1.59-1.60mm, should in conformity with the third rule
of ISO1797 standard, max length is 25mm, in conformity with ISO6360-1 standard. It might lead to the
accident like sudden snapped, throw out etc., if the bur is bended, aw, variant, damage and inconformity,
cause hurt and damage the handpiece.

12
2.6.8 Install the bur or the standard stick on the handpiece, even it is not in use.
2.6.9 Please don’t install or un-install the bur or handpiece until the machine is totally stopped.
2.6.10 The pressure and ow of the air and water source must meet the requirement of this machine.
2.6.11 Use the dry, clean compressed air to make sure the working life of the handpiece, maintenance the
air compressor, air and water lter system regularly to ensure the quality of compressed air and water. Use
unltered water might lead to block of pipeline joint and earlier damage of atomizing.
2.6.12 This machine could not be used in easy exploded environment, such as anesthetic gas.
