4.4.3 Cautions when replacing the PF Loop Scale

4.4.3.1 Assembly Procedure for the PF Loop Scale ASSY

When assembling the PF loop scale unit, the following exclusive tool should be used.
Exclusive tool No.#F730
The assembly procedure is shown below.
1. Set the exclusive tool, #F730 as shown in the figure below, then set the PF loop scale
base part with the double sided tape side facing up.
2. Peel the protective backing off the double sided tape to the PF loop scale base.
3. Affix the PF loop scale carefully to the PF loop scale base with the PF loop scale
printed surface downward, aligning it precisely with the PF loop scale base.
4. Peel the protective backing off the other side of the double sided tape and affix the tape
so that it is within the black circle on the unprinted side of the PF loop scale ASSY.
Care should be taken so as not to damage the internal diameter

of the PF loop scale.
There is no problem if the PF loop scale's affixing position on
the PF loop scale base deviates somewhat. The important
control point is that the inside diameter of the PF loop scale not
be damaged.
