2.4.1 Inspecting and replacing the air filters
The filters should generally be inspected every month, although this depends on the supply air condition and
the operating time. The filters for the RM head cannot be reused. Replace the filters if contaminated.
Note that using filter insertion tool is convenient to replace multiple filters at once. The following describes
how to replace filters with the tool.
TIP
See "RM head" of "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 "8.1 Cleaning inside of nozzle shaft on RM head unit".
1
Prepare for work.
e
1. Remove all items sensitive to magnetic fields
such as wristwatches and magnetic ID cards.
2. Return all nozzles (if the machine is installed
nozzle station).
3. Press the emergency stop button and detach
feeder exchange carriage.
4. Open the machine safety cover and move
the head unit frontward.
5. Place a square cloth under the head unit.
n
NOTE
When the nozzle station is not installed, remove all the
nozzles by hand.
2
Check the filter codition.
1. Remove 4 bolts on the acrylic board
mounted at the reverse side of head using a
hexagon wrench.
2. Check the filter visually through the window-
like opening.
n
NOTE
The RM head nozzle shaft can be rotated by rotating the
R-axis gear by hand. When rotating the entire holder is
required, rotate the N-axis gear by hand.
3
Detach the filter.
1. As shown in the figure at right, push out the
filter from the end of nozzle shaft using a
flat-head precision screwdriver.
2. Turn the N-axis gear by hand to rotate the
rotary and detach the filters on the opposite
side.
n
NOTE
The filters for the RM head cannot be reused once they
are detached.
As a general guide, the filters should be replaced once
every month, although this depends on the operating time
of the machine. Periodic filter replacement is
recommended.
The filter for RM head:
• 20-pack (KMB-M3856-00X)
• 1000-pack (KMB-M3857-01X)

Set new filter into hole of filter insertion
tool.
1. Insert needle pierce into hole of filter.
2. Insert filter deeply into hole of tool. At this
time, be careful not to deform the filter, and
also to align the hole number with the
number of shaft which filter is to be
replaced.
c
CAUTION
Make sure to set the filter facing up the hole side.
5
Insert tool into shafts.
1. Align the tool hole number with the number
of shaft which filter is to be replaced.
2. Push up the tool completely to arrows'
direction as shown on the right.
c
CAUTION
Make sure to push up the tool completely. If pushing up
the tool incompletely or insertion position is deviated,
filters get deformed.
6
Check that filters are surely inserted
into shafts after detaching the tool.
7
Attach the acrylic board removed in
Step 2 to its original position.
8
Return nozzles to original positions if
nozzles are detached manually.
1. Return nozzles to original positions.
2. Retrieve the square cloth.
n
NOTE
Make sure to return the nozzle to the head from which the
nozzle is detached.
c
CAUTION
Make sure to return all nozzle shafts to the original
position after lowered nozzle shafts manually.
