Dental handpieces right use way:
1. The need to use a clean , dry , oil-free air compressors for medical use ;
2. The air pressure between 2.3-2.8kgf / cm2;
3. Place the adapter with quick connector at the bottom of a combination of dental handpieces , and confirm that the card lock fixed ;
4. Press the pedal, handpiece operation and examine whether the normal operation of the spray head. If everything is normal, you can start using the handpiece .
After each patient use , maintenance should be done as follows
1. First remove the diamond burs , and clean up all the teeth on dental handpieces precipitate ;
2. Use a metal needle to clean the spray holes and fumaroles ;
Note: The spray holes and diamond burs into 40 -degree angle , fumaroles and diamond burs to a 30 degree angle.
3. Place the clean lubricating oil is sprayed into the axial hole 1-2 seconds ( diamond burs is plugged holes ) ;
4. In the bottom of the handpiece were ( with / without quick connector ) two kinds of styling , make the right amount of lubricant is injected into the bottom ;
5. The handpiece with quick connector combination ( first determine the water switch is turned off )
6. Replace the diamond burs , surrounded by white silk cloth handpiece head ( make sure the needle does not touch the diamond burs and white gauze , so as not to tie ) ;
7. pedal depressed for about 20 seconds , look at whether there is in white gauze on any stain. If there are stains on the white gauze , again, add oil , starting from item 4 continued routine maintenance , know that white gauze until no stain ;
8. Finally, no more than 135 degrees Celsius temperature and high pressure sterilization.
Handpiece routine maintenance
Fault: the occurrence of undesirable phenomena water
( 1 ) inadequate water supply .
( 2 ) the amount of water is not uniform.
( 3 ) is not a mist of water .
( 4 ) no water completely .
Solution: Check the water blocked the site
( 1 ) pipeline : the turbines removed to check for the amount of water flowing from the pipeline . If there is no water out, it may be pipes or water treatment units system problems ( bad or wrong operation , there is not enough water pressure ) .
( 2 ) interface : the interface conductors commissioning . Without the right amount of water flowing out , it indicates a problem at the interface ( such as clogged scale water supply systems or interface loose , resulting in insufficient pressure ) .
( 3) The body of the phone : the shaft from the turbine to remove , install interface running on . If there is no outflow amount of water, it is the problem turbines within the body ( water holes or dirt clogging turbines within the water supply system clogging ) .
( 4 ) shaft : If the above three normal outflow of water , it is the axis of the core problem (water nozzle clogging ) .
Axis core spray nozzle clogging .
( 1 ) remove the end cap , remove the spool core .
( 2 ) the brush behind the nozzle cleaning needle is removed , insert the needle straight spout .
( 3 ) nozzle cleaning needle to be inserted into the upper section of the trench ( bur through jet slot ) at the till . Part of this special brush with dust brush clean.
( 4 ) the use of three guns and other bur blowing from the side .
(5 ) mounted on the shaft head , be sure to properly install the 0 -ring .
bur easy to fall off , bur not pull it out , the axis vibration.
(1 ) Select the bur , bur must confirm the allowable speed range specified by the manufacturer , or else when the cutting load is greater than the chuck clamping force bur easily.
( 2 ) mini- head bur should use a short handle , easy to fall off when attached to the shank burs .
( 3 ) Do not use worn tapered bur , curved bur bur missing edge , otherwise it will affect the durability of the bearing Must be drawn .
(4 ) installation bur bur confirm indeed firmly installed , if not into the depths of shallow plug can cause dangerous bur flying .
