This section describes 3-month maintenance items.
3.1 MU head
3.1.1 Cleaning/replacing the air filter
The filters should generally be inspected about every 3 months, although this depends on the supply air
condition and the operating time. If the filter is contaminated slightly, it can be cleaned by using an air blow
tool. Replacing the filter is recommended when it can no longer be adequately cleaned by air blowing.
1
Prepare for work.
e
1. Remove all items sensitive to magnetic fields such as wristwatches and magnetic ID cards.
2. Press the emergency stop button and then open the machine safety cover
3. Use the CLAMP ON/OFF switch to lower the feeder exchange carriage and detach it.
4. Move the head unit to convenient position to work and place a square cloth under the head unit.
2
Loosen the filter mounting plate.
Use a Phillips screwdriver to loosen the
screws that hold the filter mounting plate.
3
Remove the filter cap.
The filter cap and filter can be removed
after the filter mounting plate has been
loosened and lowered. Hold the filter cap
and pull it out toward the front of the head.

4
Clean the filter.
If the filter is only lightly soiled, it can be
cleaned by the air blow tool, and then
reused.

n
NOTE
If there are heavy dust deposits in the filter or the filter
has discolored, replace it with a new filter (KLF-M7156-
00X). As a general guide, the filters should be replaced
once every 3 months, although this depends on the
operating time of the machine. Regular filter
replacement is recommended.
5
Reattach the filter cap.
1. Reattach the filter cap to the filter, and
return the filter to its original position.
2. Place the filter mounting plate over the
filter and use a Phillips screwdriver to
secure it.
c
CAUTION
Make sure that the filter caps are fully inserted before tightening the screws to hold the filter mounting plate.
6
Clean the bottom filter in the same manner.
1. Clean the bottom filter in the same manner as they are attached on both top and bottom.
2. Remove the square cloth after completing all works.
TIP
See "How to check for clogged nozzles (on the [Unit]-[Head] tab screen)" in Chapter 2 to check vacuum level after
replacing filters. If it cannot reach normal level, perform "5.1.1 Cleaning the spline shaft" in this chapter.
