Replacing the Protective White Washer
Exchange the Sealing Washer at the top of the hand piece for older Helius40 Models, newer models don't require this process.
This white washer needs to be changed to prevent dust from entering the hand piece and causing damage.
- Use the included Spanner tool to screw off the head (tip) of the hand piece (see picture below).
- Pull out the washer using pincers.
- Push a new washer into place from above into the top of the head
