Replacing the O-ring
Use the plastic O-ring removal tool (included in the support kit) to remove the old O-ring from its groove. The O-
ring may need to stretch quite a bit as it is pushed off. This requires some effort, but can be done by hand.
Clean the groove thoroughly with a soft, lint-free cloth and compressed air, if necessary.
Select a new O-ring and inspect it for damage.
Lubricate with a very light film of silicone compound (included in the support kit).
Install the new O-ring by pushing it into place and popping it into its groove.
Once in place, inspect it once more for scratches and debris, and wipe away any silicone compound deposited
on the end-cap.
Once the inspection is complete, close the instrument.
