Remark
Remove all the nozzles from the head.
* When removing a nozzle, the ball
spline shaft may be curved. Use the
nozzle changer when removing a
nozzle.
When a nozzle changer is not
mounted, hold the black holder by
hand lightly (so as not to let the axis
descend), and pull the nozzle down
straight. If removing a nozzle without
holding the black holder, a Z-axis-
motor-overload error can occur.
* See Operation manual
5-5-2.
Turn off the air and power supply.
Remove the feeder cover.
