The instrument family at a glance 1

All straight and contra-angle handpieces of the T1-LINE preparation systems are technically closely related.

You will find the code designation on the outer sleeve to identify the externally very similar contra-angle handpieces. A color ring at the interface assigns the contra-angle handpiece to the corresponding speeds.

Without doubt the clearly reduced need for special tools is an innovative advance in the T1 LINE preparation system.

Assuming equipment with basic tools, only 4 - 5 further specific tools are required.

The test equipment of the T1 TITANIUM range can be used for the final testing of the T1 LINE straight or contra-angle handpiece.

All contra-angle handpieces - the locking principle 4

All handpieces of the preparation system T1 LINE are locked in the same way:

The wire clip 16 is anchored in the head. The nuts 17 at the end of the wire clip are supported in the coupling bush 7 and brace the assemblies 28, 3, 24, and 7.

The ring nut 2 pulls the block of the assemblies against the end of the outer sleeve. The gap between outer sleeve and head is reduced to zero.

The drives 1:1 to 6:1 have the same construction and differ in appearance only in the drive shaft. For these drives the uniform dismantling process is described on the following pages.

All drives at a glance 6

A separate chapter is devoted to the somewhat more complex 24:1 drive, cf. page 16.

1 With tool B the pin 30 can be remo-

ved easily and without damaging other parts: Unscrew knurled nut G until the thread becomes visible. Insert the drive 24 so that pin E guides the elongated hole in the drive and the spring loaded pin F is aligned with pin 30.

3 Drive shaft 2 and ball bearing 7 are bonded to the

bearing flange 1. The ball bearing 6 is only pushed in.

Place the bearing flange as shown and loosen the bond with a light tap on the drive shaft 2 (mallet).

4 Eject drive shaft with matching drift punch.

Should the bond of the ball bearing 7 have been stronger than that of the drive shaft, then detach ball bearing carefully from the bearing flange 1 with a suitable drift punch H.

2 Apply dosed Araldite AV 119 to bearing

flange 1, in the seat of the front ball bearing. Push in drive shaft 2 with ball bearing up to stop.

Each drive has its own dimension between the end of the gear and the end of the bearing flange

dismantled in the same way:

Insert head in tool C. Grip neck of the head with pliers D and unscrew.

Here check the dimension "E" during assembly. It lies between the ball bearing upper edge and the first heel in the head housing and is: 1.34 to 1.38 mm. Insert adjusting washer 6 0.08 mm and insert head drive. With tool F – from the T1 TITANIUM tool set – determine the dimension "E". Any size lying between the above mentioned key values is correct. If required select another adjusting washer to achieve the dimension.

Head - replacing spray ring up to Serial No: 14 999 13

1 Spray rings made of elastic material determine the

number of nozzles in the heads. If these should need to be replaced, simply grip the spray ring with a pointed probe in a nozzle bore and withdraw it.

E (41 74 343)

2 Each spray ring has a gradation on its outer circumference.

If a new ring is placed in position, this gradation must be underneath (head side); see also sectional drawing page 21. Press down new ring with your finger tip. Press down the projecting edge with tool E, in small steps and with pushing movements towards the chuck.

Head - replacing spray ring from Serial No: 15 000 14

You can replace a defective spray insert. This requires the corresponding repair set for 1D, 2D or 3D with tools for this. First the instrument must be removed from the head and any deposits must be cleaned off from the front head end. Then unscrew the spray screw 2 with the spray key K counterclockwise.

The spray key is suitable both for FG chuck systems (thin guide mandrel K.1) and for WM chuck systems (thick guide mandrel K.2).

Then insert the dismantling tool L in the spray insert 4. Press the dismantling tool together and draw the spray insert 4 out from the head.

K.2

K.1

CAUTION! Do not use O-ring and spray screw any more.

Clean the chamber clean the air and water channels, possibly with the cleaning wire M. Then let the instrument run briefly with spray to flush through the channels.

Before the spray insert 4 is inserted, a new O-ring 6 must be pushed on with the slip-on sleeve N. For this purpose insert the spray insert up to the stop in the slipon sleeve and push on a new O-ring.

CAUTION! The O-ring must not come to lie in the ring channel

Then spray the O-ring with T1 spray, determine the position of the spray nozzle(s) and install the spray insert in the head.

Tighten the spray insert with a new spray screw with the spray key.

Finally, operate the instrument with cooling spray and check the spray pattern.
