2) Detach the magnescale head from the bracket.
3) Peel off the old magnescale.
4) Degrease the magnescale mounting surface and magnescale completely.
Note 1: Before replacing the magnescale, put the magnescale near the machine and leave it
for 1 hr. or longer to make the temperature of the magnescale similar to that of the
machine.
Note 2: “Mecha fine mate” is recommended for the degreasing agent.
Note 3: Deviation amount when compared to the specified value of the magnescale in the
X-direction: ±0.1 mm or less.
Note 4: Do not put any magnet, such as magnetized screwdriver or support pin close to the
magnescale. Doing so may cause the magnescale to malfunction.
Note 5: The magnescale has the affixing orientation. Affix the magnescale in the same
orientation as the S/N shown in the Figure. For details about magnescale to be used,
see the List below.

1-2-1. X-Axis Magnescale Affixing Position
1) With the X-axis magnescale affixing jig (40094362) put tightly in contact with the front of the
LM-guide and the bottom of the X-axis frame, make the magnescale in contact with the
X-axis magnescale affixing jig to affix the magnescale.
A marking-off line is provided at the affixing start position on the left when viewed from the
front.
Adjust the end face position of the magnescale to the marking-off line and affix the
magnescale.
Specification value: Magnescale affixing position (distance deviation in parallel to the
head moving direction) ±0.1 mm
