“THE STAR MOTOR TO ANGLE ADAPTOR REQUIRES NO LUBRICATION; HOWEVER, I’M NOT SO SURE THIS APPLIES TO THE LATCH HEAD ATTACHMENT, UNLESS ITS OEM FROM STAR/DENTALEZ. I PRESENTLY AM USING A MEGATORQUE BRAND LATCH ANGLE AS WELL AS SEVERAL NSK PB LATCH HEADS MADE FOR THE STAR MOTOR TO ANGLE ADAPTOR; CAN YOU TELL ME IF LUBRICATION IS REQUIRED, BY BREAKING DOWN THE LATCH ATTACHMENT OR BY ANY OTHER MEANS SUCH AS USING DRIVE AIR TO PROPEL LUBRICANT THROUGH THE ADAPTOR AND INTO THE GEARS OF THE LATCH HEAD. THANK YOU.”
This was our answer:
Most non brand name latch heads require lubrication. Remove the latch head by turning the collar counter clock-wise. Once removed, you should be able to pull out the shaft. With shaft removed put a couple of drops in bottom, and replace shaft. Some angle adapters have a hole in the top. If yours does, put a couple of drops there, and re-connect latch head to angle adapter. We sometimes put a couple of drops in the back end of the Star Motor to Angle Adapter prior to re-attaching adapter to motor. Boy, that was a mouth full, wasn’t it?
With all ready to operate, attach to air and run for 30 seconds or so with latch bur installed. Drive air should circulate lube as necessary to reach all components. The most important components, of course, are the bearings in the head. The Star Motor to Angle Adaptor actually has polymide bushings, which are sort of soft material for the shaft to ride on. The lube will help keep them cooler, and sometimes reduces noise. Definitely run long enough to expel excess lube prior to autoclaving any or all of the components.
Hope this helps
