5. Slowly rotate the heads at the 5mm socket head cap screw in the right end of
the Z drive shaft until the headup alignment pin tool inserts into the hole in the
headup alignment collar on the Z shaft. This is the "mechanical" headup
position for head # 4.
6. Now loosen the encoder coupler socket head cap screw at the left end of the Z
shaft (see Figure 3-10) and slowly rotate the coupling and encoder (encoder
shaft socket head cap screw is
still tight) in either direction.
Rotate until the LED on the CPU
(or the ZINDEX LED on the front
of the peripheral) glows.
7. When the LED is glowing, tighten
the Z shaft socket head cap
screw on the encoder coupler.
8. Remove the headup alignment
pin tool.
9. Remove the second socket head
cap screw and apply a small
amount of Loctite 222 (or
equivalent) hardware adhesive.
Reinstall and tighten the screw.
10. Return to the first encoder
coupler socket head cap screw,
remove the screw and apply a
small amount of Loctite 222 (or
equivalent) hardware adhesive,
then reinstall and tighten the screw.
11. Turn the embroidery peripheral OFF and attach the network cable (or install the
boot disk if the disk drive option is installed).
12. Turn the embroidery peripheral ON again and allow its program to download.
13. Go to the head timing menu and check that when the heads are brought to
headup, that the ZINDEX LED on the front of the right frame leg of the
peripheral (or the innermost LED on the CPU) glows within plus or minus 1.5
degrees of rotation.
14. Reinstall all covers removed during this procedure.
