Periodic maintenance items
2. Monthly or bimonthly inspection
This section explains how to clean and lubricate a nozzle holder after inspection.
2.1 Cleaning and lubricating a nozzle holder
If the nozzle holder buffing action (spring-action) is poor, this adversely affects all operations of component
pickup, recognition and mounting operations. Periodically (once every two months) clean the nozzle holder
with IPA or ethanol (hereafter alcohol) and lubricate it with turbine oil to maintain smooth movement.

1
Press the emergency stop button.
The machine must be in emergency stop to
ensure safety during work.
2
Remove the nozzles and lower the
heads.
Remove the nozzles attached to the nozzle
holders to be cleaned, and then lower the
heads by pressing the [Head] button on the
[Unit]-[Head] tab screen.
3
Clean the nozzle holder by
immersing it in alcohol.
1. Place a cloth or paper towel under the
head.
2. Prepare a small container of about
10mm diameter deep enough to hold
the entire nozzle holder. Then pour this
container about 80% full of alcohol.
3. Bring this alcohol container up against
the nozzle shaft so the entire nozzle
holder is immersed in alcohol for several
seconds.
4. Remove the alcohol container and push
up on the nozzle holder with your finger
several times.

4
Immerse the nozzle holder in
alcohol again.
Repeat steps 3 and 4 until the spring-action
becomes smooth.
5
Use air blow to remove foreign
matter.
Insert an air blow gun into the air joint
section and blow air while holding a
cleaning cloth or paper towel against the
lower end of the head.
6
Lubricate the slide section and
check the movement.
Apply turbine oil to the buffing section (slide
section) and push up the nozzle holder by
hand several times to check that it moves
up and down smoothly.

8
Blow off excess oil remaining in the
nozzle.
As in step 5, insert the air blow gun into the
air joint section and blow air through the
spline shaft while holding a cleaning cloth or
paper towel against the lower end of the
head.
9
Check that the oil was removed.
If needed, blow air through the spline shaft
again while using commercially-available oil
blotting paper, and check for residual oil in
the nozzle.

NOTE
Performing step 8 is usually sufficient to remove residual
oil. However, if oil still remains then blow air once again.
0
Reinstall the nozzle.
Reinstall the nozzle back onto the head after
checking one more time that there is no oil
remaining there.
Step 9
Checking for residual oil
Oil blotting paper
Oil will appear after blowing air (first
time) for about 5 seconds from the
nozzle tip.
Repeat the air blow for about 5
seconds each from the nozzle tip
and from the attachment side.
This task is finished when oil no
longer appears.

2.2 Cleaning and greasing the X, Y, YT and W axis ball screws
e
1
Press the emergency stop button.
The machine must be in emergency stop to
ensure safety during work.
2
Clean the ball screws.
1. Move the head (or conveyor table or
rails) to one end of its axis.
Use the handle when moving the head.
2. Wipe away the old grease and dirt from
the ball screw with a lint-free cloth or
paper towel (for clean room use).
3. Move the head (or conveyor table or
rails) to the opposite side of its axis and
wipe the ball screw.

CAUTION
Wipe away thoroughly the old grease in the lead
groove of the ball screw. Also check that no debris and
residue remain in the lead groove.
3
Apply new grease to the ball screw.
1. X, Y and YT axes
Use a grease gun to supply the specified
grease (NSL) through the ball screw
grease nipple.
2. W axis
Apply the specified grease (NSL) by hand
uniformly over the surface and lead
groove of the ball screw.

NOTE
• When greasing, we recommend using a bent type
grease gun nozzle (K48-M3854-00X available as an
option).
• Inject grease into each grease nipple until new
grease comes out.
4
Remove excess grease. (X, Y and YT
axes)
1. Move the head (or conveyor table) to
one end of its axis.
Use the handle when moving the head.
2. Wipe away excess grease from the ball
screw and the nut edge.
3. Move the head (or conveyor table) to
the opposite side of its axis and wipe
away excess grease from the ball screw
and the nut edge.
