Clean the X-axis linear guides.
1. Move the head to one end of the X-axis,
and wipe away the old grease and dirt
from the linear guides with a lint-free
cloth or paper towel (for clean room
use).

CAUTION
Wipe away the old grease and dirt in the grooves of the
linear guide rails.
3
Apply new grease to the linear
guides.
Use the grease gun to supply the specified
grease (NSL) to the grease nipples. Two
nipples are vertically located in the following
position.
• Tables A and D: Right side of head unit
• Tables B and C: Left side of head unit

Remove excess grease.
After moving the head back and forth a few
times along the X-axis, wipe away excess
grease.
c
CAUTION
Repeat the above steps until finally there are no longer
any grease deposits. If production starts with grease
deposits still remaining, this might cause grease to
spatter and badly affect the production yield.

e
1
Press the emergency stop button.
The machine must be in emergency stop to
ensure safety during work.
2
Remove the Y-axis covers.
1. Move the X-axis beam to the front side of
the machine (toward you) and remove
the two screws securing the rear side
(inner section) of each Y-axis cover.
c
CAUTION
Be careful not to drop the screws that secure the
covers.
2. Move the X-axis beam all the way to the
rear side (inner side) and remove the two
screws securing the front side (outer
section) of each Y-axis ball screw cover.
3. To remove each Y-axis ball screw cover,
first pull the cover to the front side (outer
side) of the machine so that the inner
end of the cover comes out of the X-axis
frame. Then move the cover back to the
rear side (inner side) and remove it.

Remove excess grease.
1. Using the handles, move the X-axis beam
back and forth a few times along the
Y-axis to spread grease over the entire
ball screw.
2. Wipe away excess grease from the ball
screws and the nut edges (outer and
inner sides).
6
Reattach the Y-axis covers.
Attach the covers in the reverse order of the
removal procedure in step 2.
c
CAUTION
Be sure to reattach the covers back to their original positions. If production starts without reattaching the covers,
spattering grease might badly affect the production yield.
