This section describes 1-year maintenance items.
5.1 HM head: Cleaning the spline shaft interior
Generally, the spline shaft interior should be cleaned once a year. Perform the following procedures.
1
Store all the nozzles to nozzle station.
1. Open the [Unit] - [Head] screen.
2. Select any head unit from "Table Select".
3. Press the [Nozzle Change] button.
4. Select "ALL" for "Head Number" and select
"Store Nozzle" for "Nozzle Type" on the
"Nozzle Change" screen.
5. Press the [OK] button to return all nozzles to

Move the head unit.
1. Press the emergency stop button and detach
the feeder exchange carriage.
2. Open the machine safety cover and move
the head unit to convenient position to work.
3
Pull out the lower end of air hose.
4
Fix the Z-axis as shown in the figure
right, by placing the Z-axis linear scale
hidden by shaft, and by inserting a
hexagon wrench into the Z-axis fixing
hole.
n
NOTE
As there are cables around the head and they may
prevent a hexagon wrench to insert into the hole. In such
case, use a wire (less than
φ
2.5mm) or similar instead to
mount the Z-axis.
TIP
The common type hexagon wrench can fix approximately
5 heads at once. HM head unit has 10 heads, so cleaning
them in 2 part is recommended.
5
Detach the maintenance bolt using a
flat-head screwdriver or a precision
spanner.
6
Prepare for cleaning.
1. Place a paper cup or a lint-free cloth

might flow out on the packings.
8
Blow air into the spline air path.
1. Prepare an air blow tool (option) and
connect it to the air connector located at the
center of the feeder exchange carriage.
2. Close the hole pulled out the air hose to
prevent the air leakage, then air-blow the
spline shaft interior.
3. Check that the soiled ethanol has not been
exhausted from the tip of spline shaft.
n
NOTE
Repeat Steps 6 and 7 until the ethanol flown out from
spline shaft becomes clear.

Return the head to its original position.
1. Mount the maintenance bolt, insert the air
hose and attach the nozzle.
2. Pull out the hexagon wrench (or the wire)
