Hadewe Protective Washer

This protective washer is required for the older Helius 40 units as well as the Rotatool Spray units and should be changed during regular maintenance, approximately once a month, to prevent dust/fluid from entering the handpiece and causing damage. Use the spanner tool included with your unit to screw off the metal cap on the handpiece. Remove the washer with a pointed object. Push a new protective washer into place from the top of the metal cap until is sits securely in place. 10/package
