Use a flat-head screwdriver or precision
wrench to remove the maintenance bolt
and pull out the air hose.
4
Mount the Z-axis at the work position.
As shown in the figure on the right, move the
shaft to a position where the Z-axis linear
scale is hidden and insert the hex wrench into
the Z-axis mounting hole to mount the Z-axis.
n
NOTE
A hex wrench may not be inserted easily as cables are
around the head. In this case, use a wire (less than
φ
2.5
mm), etc. to mount the Z-axis.
