MCS Handpiece Repair's Handpiece Maintenance

Handpiece Cleaning & General Maintenance

     We believe Good Maintenance will help the Life of a Handpiece. The following Guidelines represent a General Approach to Handpiece Maintenance. Always follow the Suggested Maintenance Procedures supplied with the Handpiece, especially during the warranty period. It is important to follow these instructions to the letter to avoid Premature Failure to newly installed parts. 

Tips & Tricks for Handpiece Maintenance.

- Make Sure your Handpiece is well Lubricated.

     A High Speed Handpiece bearings spin over 400,000 rpm. (rotation per minute) This is very fast for parts to move. The more friction you have, the more wear and tare you have on the parts. Lubricating the handpiece, including the bearings, will decrease this friction, thus prolonging the life of the bearings. However, because bearings spin over 400,000 rpm, these are the first part of the handpiece that will deteriorate. Much like tires on a car.


     Lubrication also cleans the entire handpiece, flushing out debris that could gum up inside. This also includes the chuck mechanism. When debris is lodged in the handpiece, from either water lines to the chuck, the air pressure will push the debris, usually, into the bearings and chuck mechanism. This does more damage to the bearings, causing them to seize, or break inside the handpiece.


     If you are using an Ultra Sonic for cleaning, we recommend to Lubricate your Handpiece twice, steps A through D in the Handpiece Maintenance Procedure. This will help remove water from your handpiece, and prevent rust build up as well.

- Make Sure Autoclave Temperature is at 130c.

     If the autoclave temperature is over 132 degrees Celsius, it can literally melt the orings and bearing retainer, inside of the handpiece. You will experience; air loss, low torque, and water leaks.

- Make Sure Chuck Mechanism is Cleaned After Every Use.

     Using the chuck brush is a great way of cleaning all the debris that can get clogged in the chuck. Adding lubrication to the chuck brush while cleaning the chuck is optimal. We suggest to use the chuck brush after each use. Click Here for prices on Chuck Brushes. 

- Sterilization Wipes

     We recommend not to use sterilization wipes on your handpieces, or motors. These wipes, like the bur sterilization compound mentioned above, leaves a residue on your handpieces. This residue transfers to all moving parts causing them to fail prematurely. We do recommend pure rubbing alcohol without any additives in addition to your sterilization methods.

- We Suggest Not To Reuse Burs.

     We have seen many handpieces come in for repair with bearings issues. One of the biggest issues is reusing burs. Reusing burs may cut costs on purchasing more burs in the future, however, it actually does more damage to the bearings. Reused burs are dull and damaged, thus causing the operator to apply extra pressure to cut faster. When doing so, this causes extra pressure on the bearing retainer causing the bearings to fail prematurely. Reused burs are, 90% of the time, bent to a small degree that the human eye cannot detect, thus causing small vibrations, damaging the bearing retainer. When the handpiece is taken apart, more than often we will see parts of the bearing fall out of the handpiece. If reusing burs is a must, we recommend not using sterilize compound agents.

     Sterilize compound agents come in many forms; compounds, wipes, agent, and sprays. This compound leaves a residue on the bur, and when the bur is seated in the chuck, this residue is transferred, causing the chuck to “gum up” with debris more quickly, almost acting like a glue. Once the chuck is gummed up with debris, burs will not be seated properly, and possibly become loose while in use. We suggest to simply do not reuse burs. The cost of a new bur is much less than always having to repair your handpieces.

- Do Not Remove a Handpiece from the Autoclave Too Early.

     Removing the Handpiece before the Drying Cycle is complete or before the Handpiece has Cooled Down will cause condensation build up inside the handpiece which will lead to internal rust and the handpiece will be ruined.

- Do Not Leave Burs In the Chuck During Autoclaving.

     When burs are installed in an AutoChuck, the springs in the chuck are under tension. Applying extreme heat while under tension will weaken the springs and reduce the lifespan of the chuck. When burs are left in a manual chuck it can cause a build up of debris inside the chuck causing problems during operation.

- Make Sure to Check Your Air & Water Lines for Debris.

     Having contaminated air or water lines can also contaminate all handpieces that use those lines. You can check if you have dirty lines by purging the lines onto a clean white paper towel. If you see any dirt or discoloration, your line may be contaminated.

We recommend to Soak your Handpieces in Lubricant Over Night, at least Once a Month.
This will help remove stuck on debris and saturate bearings for longer life.
