Periodic maintenance items
2.3.3
Inspecting, cleaning and greasing the PU (push-up) shaft (option)
The push-up shaft is designed to prevent flexing or warping of the board during clamping and is important
because it prevents depressing of the board during component mounting.
The push-up shaft also prevents deviations in the component mounting accuracy due to the board depressing
during component mounting, so it is important to regularly clean and inspect the push-up shaft to ensure it
operates correctly.
c
cleaning of the push-up shaft by the user will void the warranty.
n
Required tools
• Hex wrench (3mm)
• Specified grease: NSL

3. Three-month inspection
3.1 Head
This section describes the maintenance procedures, using the V2 head machine as an example.
3.1.1 Cleaning and replacing the ejector filter
Although depending on the air supply conditions and operating time, ejectors should be inspected once every
3 months. Use an air blow tool to remove dust buildups when small. We recommend replacing the air filter if
heavy dust deposits are found.
n
Required tools
• Square cloth
• Precision slotted screwdriver (option)
• Tweezers
• Air blow tool (option)
• Replacement parts (See 2.1.1 “Consumable parts and replaceable parts (for repairs)” in Chapter 1.
c
n
NOTE
Before beginning the work, put a square cloth on the conveyor to prevent any parts from being lost or dropping into
other sections and causing trouble.
1
Move the head all the way to the
front end of the Y axis.
On the [Unit]-[Head] tab (or [conveyor] tab)
screen, press the [Axis] button to open the
"Move Axis" screen. Then move the head
assembly all the way to the front of the Y
axis (front of machine).
TIP
The ejector unit is located at the front of the head
assembly. It is easier to inspect the ejector filters when
the head assembly is positioned to the front side of the
Y axis. (Inspect the ejector filters from the front of the
machine.)
e
2
Press the emergency stop button.
The machine should be in emergency stop
to ensure safety during work.
3
Remove the filter cap.
Loosen and remove the filter cap with a
slotted screwdriver.

4
Clean the filter.
Use tweezers to take the filter out of the
ejector. When there is only a little dust in the
filter, use an air blow tool to blow it away
and return the filter back to the original
position.
n
NOTE
If there are heavy dust deposits in the filter or the filter
has discolored, replace it with a new filter (K46-M8527-
C0X). As a general guide, filters should be replaced
once every 3 months, although this depends on the
actual operating time.
