Are You Having Trouble Removing Your Star Highspeed From The Quick Coupler?
First Let’s Get it Off the Quick Coupler:
- Take A Flat Bladed Screwdriver And Insert it Between The End Of The Star 430 Handpiece & The Hose Coupling.
- Gently Turn The Screw Driver. Make Sure Contact Remains Between The Coupling and The Backend of the Handpiece. Do Not let it slip or damage may occur.
- With a little bit of Pressure, you will Feel the Handpiece Slip Past the O-ring.
- At this point, remove the screwdriver, set it down and Simply pull the Handpiece Off The Quick Connect as you normally would.
Now Let’s fix the Source of The Problem. Take a Q-tip and moisten it with WD-40 and clean the backend of the Star 430 Handpiece by wiping it across the surfaces of the O-ring Grooves inside the inner housing. Repeat as necessary until there is no visible color change of the WD-40 on the Q-tip. Take a dry Q-tip and remove as much of the WD-40 as possible. It does not hurt to follow this up by blowing a little dry air from your syringe inside, forcing any remaining residue out. We don’t want the WD-40 getting into the bearings. It’s time to Check the O-rings on the Quick Connect for the Star 430. Look for Cracking, Brittleness, or actual breakage. If any of these conditions exist, replace the O-rings. They are relatively inexpensive and it’s a good practice to always have a couple of sets on hand. Lubricate the new O-rings if replaced or the old ones if not replaced, with a drop of Handpiece Oil. It’s also a good idea to replace the O-rings at least every 12 months, even if they look fine The O-rings on the Quick Connect Should Be Lubricated Weekly, As per Manufacturers Specifications. The Lubrication Extends the lifespan of the O-rings, provides ease of connect and disconnect of the Handpieces, and it also helps keep the backend free of debris that could cause the Handpiece to get stuck again.
Tech Tip: I have answered several Service Calls where the Star 430 Handpiece Quick Connect cannot be removed from the supply tubing. To keep this from happening and incurring the expense of a Service Call, the Quick Connect should be removed from the Hose connection periodically, and the threads lubricated with a drop of oil or Handpiece Grease to keep it from being frozen in place. Once a Month or so should keep this part of the Operation relatively Trouble-Free.
