Richard Rosenblatt I just had my annual maintenance on my Omni and MCXL this morn. Patterson techs do such a great job when they come out. They really know the machine and give lots of great tips on maintenance for our daily routine. I got a good one today that I thought I would share. He told me that the water jets that shoot water to the tip of the burs had some clogs in them. For those that don’t know where the water jets are, this is a close up of the 3 small holes where water is aimed at the tip of each bur. 
These holes can get clogged occasionally with some of the milling debris. If all 3 jets are not hitting the end of that bur, you are going to go through a lot more burs than you would like. Try these steps:
- Close the lid and hit the pump button. This will purge the water through the jets and let you see if water is coming out of all 3 ports. In the pic I have included, you can see water is coming out of all 3 but the tech told me that I had a few that were not firing water to the tip of the bur.
- Once you determine which ports may be clogged, get a 15 or 20 new endo file and insert into each individual port. You can see by the pic that there is a definitive angle you need to get to insert the file properly into the port. Do this with each clogged port and then try the pump button. Repeat until all ports are clear and freely flowing.
He recommended doing this weekly when we change the water to make sure it stays clear and free flowing. I now have my mcxl and omni with new filters, cleaned, calibrated and ready to take on whatever I can bring it. Thanks again Patterson for you service and knowledge with this technology!
