Whenever new O-rings installed, or after frequent usage; the plunger on the stainless steel syringe may feel tight and cannot push/pull by hand. In this case, the syringe will need to be lubricated by following these steps:
- Pull the plunger out of the syringe
- Using an electrical grade Silicone lubricant spray sparsely within the syringe’s inner surface wall; rotate the syringe as necessary for even spraying. If overspray occurs, use lint-free paper to wipe down the excess lubricant.
- Insert the plunger, move the plunger back and forth with slight rotation for even distribution.
