from the Z-arm.

1 Using the 3 mm Allen wrench included in the GX-27X accessory package,

remove the screw from the bottom of the isolator mounting block on the
Z-arm.

2 Slide the isolator mounting block down as far as it will go to the bottom of

the Z-arm.

Note: There may be some resistance when sliding the isolator mounting
block.

3 Lay the Z-arm on its back on a flat surface.

The guide foot is installed on the Z-foot of the Z-arm.

probe guide insert should be oriented so the wider part is at the bottom and
the three holes are at the top.

with the holes on the Z-foot.
