Before fitting the new spray insert (4), you must push on an
O-ring (6) with the push-on sleeve (7). To do this, push the
spray insert fully into the push-on sleeve and slide on a new
O-ring.
ATTENTION! The O-ring must not lie in the ring duct (D).
Next, spray the O-ring with T1 spray, determine the position
of the spray nozzle(s) and plug the spray insert onto the
head.
Using the spray key, tighten the spray insert firmly with a
new spray screw.
ATTENTION! Otherwise there is a risk that the spray in-
sert may come off and fall into the patient's pharynx together
with the spray screw.
Finally, operate the highspeed handpiece with cooling spray
and check the spray outlet.
