●If the display value is not within the prescribed value range,
・Check the supply pressure of the vacuum pump (→P4-1-1)
・Clean the nozzle holders (→P5-2)
●If it still stays out of the prescribed value range, contact us.
●Prescribed value: value in the frame is less than "-85".

Inspecting the θ-axis
belt (Placement head(option))
Describes how to inspect θ-axis belt by using the 12-nozzle head as an example; however, the same
procedure is also applicable to the light weight 16-and 8-nozzle head.
Tool used: Allen wrench (size: opposite side 2.0 mm (a ball-point-end) and 2.5 mm)
Time required: 10 minutes for light weight 16-nozzle head, 10-minutes for 12-nozzle head and 20 minutes for
8-nozzle head.

Insert an Allen wrench into the end of the θ-axis pulley of the head edge, and
then turn it around 10 times or more
●It has no problem if showing no variations in the rotational torque.
●If showing some variations in the rotational torque (Rotational resistance can be either high
or low sometimes while turning it around), contact us.
●Two θ -axis motors are located on the right and left sides. Inspect both of them.
●For 8-nozzle head, remove the nozzle protection guard during inspection.
(For light weight 16-, and 12-nozzle, you do not need to remove it during inspection.)
*Use a ball-point-end Allen wrench (the
one at the top of the photo above)
