2.6 RS head
How to lower RS head/nozzle shafts
Maintenance of the RS head requires lowering the nozzle shafts manually in sequence as for example in "2.6.1
Inspecting and replacing the air filters" and "3.2.1 Inspecting/cleaning nozzle shaft tip". This method is
described below.
1
Press down Z-axis of RS head.
The Z-axis units are located on both sides of RS head unit for lowering nozzle shafts. The nozzle shafts
under Z-axis can be lowered by pressing down Z-axis manually.
2
Change the nozzle shaft to be lowered.
Move a nozzle shaft under Z-axis by gripping and turning the rotary unit’s label ring (part on which the
nozzle shaft numbers are printed) located on the bottom of RS head.
c
CAUTION
Make sure that all nozzle shafts have returned to upper end after having lowered the nozzle shafts manually,
n
NOTE
The rotary unit can also be turned by turning the R-axis gear manually.

2.6.1 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 RS 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 "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.
1
Prepare for work.
e
1. Remove all items sensitive to magnetic fields such as wristwatches and magnetic ID cards.
2. (With nozzle station) Return all nozzles to the nozzle station
3. Press the emergency stop button and then open the machine safety cover.
4. Use the CLAMP ON/OFF switch to lower the feeder exchange carriage and detach it.
5. Move the head unit to convenient position to work and place a square cloth under the head unit.
2
Check the filter condition.
1. Turn the rotary unit so that the nozzle
shaft to be inspected is just under the
Z-axis.
2. Press down the Z-axis with finger to lower
the nozzle shaft.
3. (Without nozzle station) Remove detach
nozzles manually.
4. Check visually dirt on filter.

NOTE
See "How to lower RS head/nozzle shafts"" described
earlier for how to lower the RS head nozzle shafts.
3
Detach the filter.
1. As shown in the figure at right, use
flat-head precision screwdriver to push
out the filter from the end of nozzle shaft.
2. Take out the filter with tweezers.

NOTE
The filters (KMB-M7070-00X) for the RS 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.

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, align the hole number with the
number of shaft which filter is to be
replaced.

CAUTION
Make sure to set the filter facing up the hole side.

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.

Check that filters are set correctly.
Detach the tool and check that filters are
surely inserted into shafts.

(If nozzles are detached manually)
Return nozzles to original positions.
1. Return nozzles to original positions.
2. Remove the square cloth.
n
NOTE
Make sure to return detached nozzles to the head.
c
CAUTION
Make sure to return all nozzle shafts to the original
position when lowered nozzle shafts manually.

Replacing filter without filter insertion tool
Insert filter with tweezers into shaft. Then insert filter
deeply into the shaft with the tip of tweezers.
c
CAUTION
Make sure not to deform filter or damage to shaft.
