      Maintenance Tips

  • Never run a handpiece without a bur or blank burr.

  • Never put handpieces with turbines in an ultrasonic cleaner (never put anything with bearings in the ultrasonic cleaner).

  • Never cool handpieces under cold running water. (Quick cool downs are bad for turbine components.)

  • Never use a dry heat sterilizer to sterilize handpieces. (The excessive temperatures will damage bearings and other components.)

  • Ensure that your steam sterilizer does not exceed 135C (275 F).

  • Excessive air pressure (exceeding 35-40 psi) will cause damage to turbine bearings.

  • Try not to extend or use long and/or large head burs.

  • For push button turbines: do not use under or oversized burs. (Undersized - .0625 diameter, Oversized - .0630 diameter. Undersized burs will slip during use and  cause damage to the push button chuck. Oversized burs will stick or jam inside the spindle, causing damage to the push button spindle.)

  • Do not put lubricant into chuck/autochuck, put cleaner only, then expel with air with latch open.

  • Do not use high speed handpieces in labs; impression material debris is bad for bearings.

  • If you use autoclave bags for handpiece sterilization, make sure you remove them from the bag when they have cooled. Open the bag slightly to allow the moisture to dry out. The moisture trapped inside the handpiece can cause contact corrosion. 

  • Check your air and water supply filters and dryers on a regular basis.

  • Please avoid lateral pressure on the burr when operating. This added force will crack the bearing cage and cause premature bearing failure.  



       CLEANING

It is important to understand the operation of a high-speed handpiece. When a highspeed handpiece is running, it exhausts air from the top and bottom of the head. When the user lifts off the rheostat, the physics of the handpiece are reversed. When the handpiece shuts down, the turbine aspirates debris including tooth dust, amalgam and other fine particles into the head of the handpiece. You can imagine how dirty a handpiece turbine can get if the debris is not flushed out of the head prior to autoclaving. Unless it is removed, the debris will continue to bake around the turbine resulting in premature failure.
Remove the bur; cover the head of the handpiece with a spray guard or paper towel, and spray the handpiece with a high-grade synthetic aerosol lubricant using the appropriate adapter. Insert the nozzle adapter into the swivel backend or the back of a 4/5-hole handpiece.

Next, insert the bur and run the handpiece on an air station or handpiece purging station for 10 to 20 seconds (once normal speed is reached) to flush the debris out of the turbine before autoclaving. Repeat as necessary until the lubricant runs clear. Never run a manual handpiece on the purge station without a blank bur installed.

Finally, remove the bur and insert the handpiece into a bag and sterilize it. If you are using half paper and half plastic bags, remember to put the paper side up for easy evaporation. Never use dry heat and always remember to wait until the handpiece has gone through the complete drying cycle. If you are using lube-free handpieces, you can skip the lubricant and the purge station. After lubing an autochuck we feel it is better to put the handpiece on the purge station or run it without a bur in the chuck so that any loose debris can be flushed out. But do not do this with the manual chucks as they can back out of the spindle and jam in the cap.
