Apply new grease to the guide rails.
1. X axis
Use the grease gun to supply the
specified grease to the X-axis 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 guides (total of 4
places).

2. Y axes
Use the grease gun to supply the
specified grease to the Y-axis guide
grease nipples. The grease nipples are
located on the front and back sides of
the slider on each Y-axis guide (total of 4
places).
Attach the grease gun nozzle to the
grease gun so that the grease gun nozzle
can be aligned with the angle of the
grease nipples.

the grease gun nozzle with the angle of the grease
damaged or may come loose and fall off. Carefully
align the grease gun with the grease nipple.
3. W axis
Apply the specified grease to your finger,
and rub it evenly on the guide surfaces
and into the lead grooves.

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

2.3 Conveyor
2.3.1 Inspecting and cleaning the conveyor belt
Inspect the conveyor belt for wear. As the belt wears away, slippages may occur and the boards may not be
conveyed stably. It is therefore necessary to periodically inspect the conveyor belt for wear.
Belt wear may also cause trouble such as incorrect detection of the conveyor sensor due to dust from belt wear
accumulating on the light receiving surface of the conveyor sensor, or dust from belt wear accumulating in the
belt guide grooves may cause the belt to stick, etc.

Required tools
• Slotted screwdriver
• Hex wrench (4mm, 5mm)
• Vacuum ASSY (option)
1
Change the conveyor width to a
convenient width for the
maintenance work.
1. Press the [Width] button to display the
"Conveyor Width" dialog box.
2. In the "Target Width" box, enter a width
large enough for the maintenance work
(slotted screwdriver can be used) and
press [OK].
The conveyor is changed to the width
you have specified.

2
Loosen the conveyor belt tension.
Press the emergency stop button. Use 4mm
and 5mm hex wrenches to loosen the belt
tension of each conveyor.

3
Remove the conveyor belt.
Remove the conveyor belt from the pulley
and the belt groove of the board guide.
4
Check the board conveying side of
the conveyor belt for wear.
Check if the board conveying side of the
conveyor belt you have removed in step 3 is
worn out.
5
Clean the belt grooves and pulleys
on the board guide.
Use the vacuum ASSY (option) to suck in belt
wear dust particles from the belt groove or
the sensor detection surface. Also, clean the
pulley and other parts for the conveyor belt
of each conveyor.

2.3.2 Cleaning and greasing the hexagon spline
n
Required tools
• Lint-free cleaning cloth or paper towel
• Specified grease: NSL
c
Always wear protective goggles and gloves when using grease.

1
Clean the hexagon spline.
1 Set the board width to its maximum level
with manual operation and put the
machine in the emergency stop state.
2 Wipe away the old grease and dirt from
the entire hexagon spline with a lint-free
cloth or paper towel.
3 Cancel the emergency stop and make
the board width narrower. After that,
wipe also the remaining portions.

2
Apply grease.
Apply the specified grease (NSL) by hand
uniformly over the surface of the hexagon
spline.

NOTE
In the same manner as described in step 1, apply the
grease to the entire hexagon spline.
