Servomotor origin position adjustment is unnecessary. However, the
clutch vertical position and the amount of gear backlash must be adjusted.
Clutch Vertical Adjustment Procedure
(1) With the cam at 0° touch the dial gauge to the fluorescent disk and set
the gauge to zero.
(2) Using the cam handle, turn the cam handle backwards to 260°.
(3) With the cam angle at 260°, adjust the adjustment rod so the nozzle
pushes the dial gauge down to 0.25 to 0.35 mm.
(4) Repeat these procedures for other nozzles to confirm that the gap is
between 0.25 to 0.35 mm.
