1. Turn on the pressure air, and check that the pressure is 2 bar.
The pressure air supply is always the first thing to be turned on and the last thing to be
turned off! Do not proceed if the correct pressure is not established.
2. If installed, remove the spindle lock.
3. Turn on the PC, control unit (main switch in the back), and the water circuit pump.
4. Start the TRIOS software using the
5. Mount the upper geometry.
a. Check that the machine's status is Idle (on the front display or in the software) and the
spindle is freely rotating (i.e., it is not locked).
b. While idle, carefully hold the spindle by one hand and put on the geometry with the
second hand around the shaft to the topmost position. The spindle will be lifted.
not use excessive force be either of your hands!
c. Screw on the geometry by carefully rotating the spindle - never screw the geometry by
rotating the geometry itself. Beware of any excessive force applied to the geometry in
any direction!
d. Select the active geometry in the TRIOS software.
e. Check the validity of all calibrations.
Renew any outdated calibrations if necessary, or contact the guarantor.
f. Run the rotational mapping calibration whenever the geometry is reinstalled (even if it
is the same geometry as was previously installed).
6. Mount the lower geometry (if not installed already).
See the guide for detailed instructions.
7. Run the zero-gap procedure whenever one of the geometry is reinstalled.
