Press the knob for the spindle lock on the left-hand side of the cut-off
wheel, while turning the cut-off wheel until the spindle lock clicks.
Remove the nut with a fork spanner (30 mm).
Remove the flange and the cut-off wheel.
Mount the new cut-off wheel with a cardboard washer on each side.
Mount the flange and nut. Tighten carefully and close the guard.
Clamp the workpiece with the clamping device of your choice e.g. a
quick clamping device. Place the workpiece between the clamp and
the back stop.
Push the clamp towards the workpiece, and lock the quick clamping
device with the locking handle.
Ensure that only one of the quick clamping devices is tight, the
other device should only press lightly. Use support tools if the
geometry of the workpiece makes support necessary.
After clamping, test the correct position of the cut on the
workpiece, by lowering the cut-off wheel into position, min. 1 mm
above the workpiece:
Push the joystick on the Control Panel downwards, to lower the cut-
off wheel. The cut-off wheel stops when the joystick is released.

/SiC abrasives should be placed
between two cardboard washers, to protect the cut-off wheel.
For maximum precision with diamond or CBN cut-off wheels, do not use
cardboard washers.
Clamping the Workpiece
IMPORTANT
When using the AxioCut cutting mode, the cut-off wheel cover may
hit the jaw of the Quick Clamping Device, if same is mounted in the shown
forward position; ie using the cross-directional T-slot closest to the front of
the machine.
To avoid this situation, place the quick-clamping device as far back as
possible, using the front-most T-slot.
Test possible infringement by starting the machine with the cut-off wheel
completely clear of the clamping device.
Should the cut-off wheel hit the clamping device anyway, no danger is
involved. Exotom-100 will stop automatically and display the following
message: "AxioCut motor blocked".
