Using the manual block fixing

Store the block clamp tool in the corresponding holder (see also "Gluing
on the tool holder" [ → 19]).
You can attach the holder to a suitable location with the adhesive pad.
Clean and degrease the contact surface beforehand.
NOTICE
NOTE: Wear of the ball pressure screw
Wear of the ball pressure screw
The high clamping forces cause wear of the ball pressure screw.
➢ Replace the ball pressure screw every 500 clamping operations.

Fastening the block
NOTICE
Fasten the block tightly
If the block is not tightened sufficiently, this may result in falsification of
the production result and fracturing of its ceramic material.
➢ Fasten the block tightly using the block clamp tool with torque
wrench until you hear a click.
➢ Check to make sure that the block is seated very firmly.
1. Place the block (A) directly into the block fixing.

2. Clamp the ceramic block securely with the ball pressure screw (B).
Use the block clamp tool with torque wrench for this purpose.
 The block is pressed laterally against the contact surface of the
block fixing and simultaneously pulled in axially. The plate of the
block holder thus rests on the block fixing.
