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

72a

 

 

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

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 carefully 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.
