3. 6-month inspection

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.

Press the emergency stop button.

The machine must be in emergency stop to ensure

safety during work.

Open the maintenance cover.

Use a Phillips screwdriver to loosen the screws

securing the maintenance cover to the top of the

machine and remove the maintenance cover.

Take out the filter.

Loosen and remove the filter cap by hand, then use

tweezers to take the air filter out of the ejector.

43331-5E-20

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.

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.

NOTE

As a general guide, the filters should be replaced once every 6 months,

although this actually depends on the operating time.

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.

Shut off the air supply and turn off the

machine.

Open the left side cover of the machine 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.

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.

CAUTION

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

spline shaft.
