Replacing the O-rings (Motor insert)
If a deteriorated O-ring makes it difficult to attach the
handpiece or causes water or air to leak, replace the
O-ring.
Using a needle or other pointed tool, remove defective
O-rings from the motor insert section, and fit new O-rings
into the O-ring grooves.
CAUTION
The blue O-ring is thinner than the other three O-rings.
When inserting new O-rings, make sure that they are
inserted in the correct grooves as shown in the figure.
