(29) Attach the linear measure sensor emission side.
- Attaching direction of the linear measure sensor: Turn the “white mark” <shown in Fig.
E78> to the light receiving side when the poison is the origin.
- Fixating position of the linear measure sensor: Fix it at the center of the slit shown in
Fig. E79.
- Replace the 2-M1.6×L4 bolts with new one and dispose of the old bolts.
- Apply the screw lock (Three Bond 1401B) to the M1.6×L4 slightly and tighten it with
a tightening torque (Torque Driver <See Fig. E79>) by 7.5 cNm (0.76 kg f cm).

7. MSB Whole Cleaning and Lubrication Procedures
(30) Attach the Large and small diffusion plates of the head bottom surface shown in
Fig. E80.
(Large Diffusion Plate: 3-M1.6×L4 bolts, Small Diffusion Plate: 2-M1.6×L4 bolts)
- During this attaching operation, pay attention to the transparent area of the linear
measure sensor tip side section because the linear measure sensor protection cap is put
off at this time so, there is a possibility that the wrench or fingers touches that section.
Please take action to protect this section such as applying a wrench or covering this
section with plastic wrap.
- Replace the 5-M1.6×L4 bolts with new one and dispose of the old bolts.
- Apply the screw lock slightly (Three Bond 1401B) to the M1.6×L4 and tighten it with
a tightening torque (Torque Driver <See Fig. 80>) by 7.5 cNm (0.76 kg f cm).

7. MSB Whole Cleaning and Lubrication Procedures
(31) Attach the head cover. <See Fig. E81>
- The head cover becomes common use in head No. 1 and 4, Head No. 2 and 3. Turn up
the cutting section in attaching the cover. (!Caution in upper/lower direction.)
- Fix the SUS4-M3×L6 truss screws of the old type with screw lock (Three Bond
1401B). However, there is no need for the new truss screws to apply screw lock.

(32) The operations of cleaning and lubrication of MSB (Miniature Stroke Bearing) are
completed. However, it is necessary to recheck around the head section and the machine
side if the grease has adhered on the diffusion plates, or some tools have been left
behind the machine. And attach the machine safety guard cover of the upper side of the
cart detached before this operation started.
