3.1 Cleaning and replacing the ejector filter
Although depending on the air supply conditions and operating time, ejectors should be inspected once every 6
months. Use an air blow gun to remove dust buildups when small. We recommend replacing the air filter if heavy
dust deposits are found.
1
Press the emergency stop button.
e
The machine must be in emergency stop to ensure
safety during work.
2
Open the maintenance cover.
Use a Phillips screwdriver to loosen the screws
securing the maintenance cover to the top of the

4
Clean the air filter.
When there is only a little dust in the filter, use an
air gun to blow it away and return the filter to the
original position.
5
Replace the air filter as necessary.
If there are heavy dust deposits in the filter or the
filter has discolored, replace it with a new filter.
n
NOTE
As a general guide, the filters should be replaced once every 6 months,
although this actually depends on the operating time.
6
Reattach the filter cap.
Screw the filter cap back into the original position.
Do not forget to fit the O-ring inside the ejector.

3.2 Cleaning the spline shaft
Although depending on the air supply conditions and operating time, dust or grime adheres to the air path of the
spline shaft and may cause component pickup or mounting errors. The inside of the spline shaft should be cleaned
once every 6 months.
1
Shut off the air supply and turn off the
machine.
e
Open the rear cover and disconnect the air hose
from the air coupler to cut off the air supply, quit
the software, and turn off the machine power
switch.
2
Disconnect the air hose at the top of the
head assembly.
Disconnect the air hose from the air joint at the top
of the head assembly.

Clean the inside of each spline shaft.
1. Have the spline shaft cleaning tool ready and
slide the black plastic stopper on the nozzle
tube of the spline shaft cleaning tool so it is
positioned about 50mm away from the nozzle
tip.
2. Lower the head and insert the nozzle of the c
spline shaft leaning tool into the joint section.
3. Place a paper cup or similar container under the
spline shaft to be cleaned. (This prevents
alcohol from flowing out downwards.) Pour
alcohol into the hole of the spline shaft from the
top to clean away dust and grime inside the
spline shaft.

Always use IPA (iso-propyl alcohol) or ethanol to clean the
spline shaft.

Check the vacuum level.
On the operation display, open the [Unit]-[Head]
tab screen and press the [Vacuum] button to
generate a vacuum. Then check the current
vacuum level shown on the screen. When this
value is smaller than 80, cleaning of the spline shaft
is satisfactory.
