Make sure that all O-rings are on the irrigation ring and are undamaged.

If at least one O-ring is missing on the irrigation ring or damaged: replace the
O-rings.
5.4.2 Replacing the O-rings
1. Use a removal tool such as a dental hook or tweezers to extract the O-ring from
its groove.
2. Carefully pull the O-ring out. Avoid scratching the metal.
3. Insert the new O-ring by gently pressing it between your fingers to form a loop.
Do not use a tool to prevent O-ring damage.
CAUTION
Improper care of the O-rings may lead to insufficient irrigation and leakage.
1. Do not use Vaseline or other grease oil.
2. The O-rings on the irrigation ring may only be lubricated with a cotton ball wetted
with Bien-Air Dental Lubrifluid® or Lubrimed®.
