e
1
Press the emergency stop button.
The machine must be in emergency stop to
ensure safety during work.
2
Clean the linear guides.
1. Move the head (or conveyor rails) to one
end of its axis, and wipe away the old
grease and dirt from the linear guides
with a lint-free cloth or paper towel.
2. Move the head (or conveyor rails) to the
opposite side of its axis and wipe the
linear guides.

CAUTION
Wipe away thoroughly the old grease in the grooves of
the linear guide rails.
3
Apply new grease to the guide rails.
1. X axis
Use the grease gun to supply the
specified grease (NSL) to the X-axis linear
guide grease nipples.
The grease nipples are located behind
the head assembly, two each on the
right and left at the positions (heights) of
the upper and lower linear guides (total
of 4 places).
2. Y1 and Y2 axes
Use the grease gun to supply the
specified grease (NSL) to the Y-axis linear
guide grease nipples. The grease nipples
are located on the front and back sides
of the slider on each Y-axis linear guide
(total of 4 places).
3. W axis
Apply grease (NSL) by hand uniformly
over the surface and groove of the linear
guide rails.

Remove excess grease.
After moving the head (or conveyor rails)
back and forth a few times along their axes,
wipe away excess grease.

2.3 Cleaning and greasing the Z axis and rack gear
To clean and grease the Z axis used to raise and lower the spline shaft of each head and the rack gear used to
rotate the nozzles, follow the steps below. Prepare the specified grease (NSL).
1
Turn off the machine.
Quit the software and turn off the machine
power switch.
2
Remove the head assembly cover.
3
Clean the Z-axis shafts and rack
gears.
Using a lint-free paper wiper or cotton swab,
wipe the Z-axis shafts and rack gears.
Two rack gears are used: the upper one for
heads 1 to 4 and the lower one for heads 5
to 8.
Check that no hardened grease and debris
remain on the Z-axis shafts and rack gears.

and rack gears.
Apply a thin uniform coat of grease by hand
over the surface of each Z-axis shaft.
Using a lint-free cotton swab, apply a thin
uniform coat of grease over the surface of
each rack gear.

2.4 Inspecting and cleaning the air/mist filters
Air/mist filters are used to prevent oil, mist and other impurities in the air compressor from penetrating into the
machine. These filters should be inspected and cleaned periodically as instructed below. (The filter closer to
the air coupler is the air filter and the other one is the mist filter.)

Cleaning the filter cup
1
Check the inside of the filer cup.
Check for oil or water deposits in the filter
cup through the window. If the window is
dirty, follow the steps below to clean the
filter cup.
Reference
The drain cock at the bottom of the filter cup is an
auto-drain type. It automatically drains the oil or water
when deposited in the cup. We recommend
connecting a hose to this drain cock.
2
Disconnect the air hose from the
air coupler.
c
CAUTION
When disconnecting the air hose, be careful not to
allow oil, water or impurities to splash outwards.
3
Remove the filter cup.
While pressing the button on the side of the
filter cup, turn it clockwise, and pull the filter
cup downwards.

Clean the inside of the filter cup.
1. Lightly clean the filter cup with water.
2. Then, pour water-diluted neutral
detergent into the filter cup and clean
the inside while shaking it.
3. Air blow the filter cup and wipe away
any moisture with clean cloth or paper.

5
Reattach the filter cup.
1. Align the button on the side of the cup
with the attach/detach position and
push the cup upwards.
2. Turn the cup counterclockwise until you
hear a click.

NOTE
Leave the filter cup removed to clean the air filter as
explained in the next procedure.

Reconnect the air hose to the air
coupler.
After connecting the air hose, check that no
air is leaking.
