3 Press the emergency stop switch to turn off the servo.
Because working has to be performed from the rear side of the head part, work on the head on the front
side from the rear of the unit, and the head on the rear side from the front of the unit.
Press the emergency stop switch on the working side to turn OFF the servo in order to prevent the unit
from being operated mistakenly from opposite side of the unit without noticing that the other worker is
working.
[Axis center adjuting procedure]
1 Visually check that axis center of the plunger
matches.
If the axis center matches, it is unnecessary to adjust,
however, be sure to retighten the mounting bracket.
If the axis center does not match, adjust the axis
center according to the following procedure.
2 Perform adjustment of axis centers of the
mechanical valve and plunger.
1. Loosen the cap screws (2 pcs, C3 x 6)
on the mounting bracket for plunger.
2. Move the bracket back and forth to
match the axis centers of the
mechanical valve and the plunger.
3. While matching the axis center in
height direction, fasten the cap screws
(2 pcs, C3 x 6) to fix the bracket.

[Gap adjusting procedure]
1 Adjust the gap between the end of the
retracted plunger and the end of the
projected mechanical valve to 1.5 mm.
1. Loosen the cap screws (4 pcs, C3 x 5).
2. Adjust the gap between the end of the
retracted plunger and the end of the
projected mechanical valve to 1.5 mm
using a thickness gauge.
The mechanical valve and the plunger head
should be parallel to each other.
3. While matching the axis center in
height direction, fasten the cap screws
(4 pcs, C3 x 5) to fix the plunger.

• Thickness gauge
[Procedure]
1 Loosen the bolts fastening the mounting
bracket for the plunger return sensor.
2 Adjust the LED extinguishing position of the
plunger return sensor (Upper/Lower).
1. Press in the mechanical valve.
2. Pull out the plunger by hand, and
pinch a thickness gauge of t=1.0 mm
between the plunger and mechanical
valve.
3. Move the bracket to adjust the sensor
position so that the LED for the
plunger return sensor extinguishes in
this state.
3 Fasten the bolts for the mounting bracket to fix the plunger return sensor.
