1. Grasp the pressure cover with the matching recess of
key A; unscrew and remove cover.
Remove the defective rotor assembly.
Remove O-rings 72/72a from cover and housing
(tweezers, probe).
The housing of the turbine head must be clean,
remove dirt and bearing residue if necessary.
Please clean using only T1 Spray.
With each rotor change, basically both O-rings
must be exchanged!
The two new O-rings must not be inserted twisted.
To insert the new O-ring in the turbine head housing
you must first attach the guide bush supplied FB in
the turbine head housing.
The hole in the guide bush enables placing the
O-ring 72a exactly into the groove.

Replacing the Rotor Assembly
2. Carefully insert the new rotor assembly in the cover.
Screw cover with rotor assembly into turbine head by hand and
screw it tight with the prescribed tool A.
ATTENTION!
Otherwise there is a danger of the cover coming undone, thus allowing the rotor
and the drilling instrument to fall into the patient’s throat.
Then spray for one second.
3. Clamp FG instrument and stabilize it in the O-ring seats by rotating
and pulling the rotor assembly.
Let turbine run briefly without cooling spray.

Use the spray key K to unscrew the spray screw 252
counter-clockwise and remove it.
For turbines with FG chucks, use the end of the key with
the thin guide shaft K.2.
The end of the key with the thick guide shaft K.1 is used
for motor-driven handpieces with a WB chuck.
Then insert the extracting tool L in the spray cap 247.
Pinch the extracting tool and pull the spray cap 247 out
of the head.
ATTENTION!
Do not use O-ring and spray screw any more.
Clean the chamber* in the head thoroughly. If necessary
clean the air and water channels thoroughly but care-
fully with cleaning wires M.
Then let the turbine run briefly with spray to rinse the (air
and water) channels.

Before inserting the new spray cap 247, you must slip an
O-ring 251 onto it with the attachment sleeve N. This is
done by inserting the spray cap in the attachment sleeve
up to the stop and then sliding a new O-ring over the
sleeve and onto the cap.
ATTENTION!
The O-ring 251 has not to damaged and must
not come to lie in the ring groove**.
Then spray the O-ring with T1 Spray, set the position of
the spray nozzle(s) and insert the spray cap in the head.
Use the spray key to fasten the spray cap with a new
spray screw.
Then run the turbine with cooling spray and check the
exit spray.
