[Gap adjusting procedure]
1 Adjust the gap between the end of the re-
tracted 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.

[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.

4 Check the LED lighting-on state 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=1.2 mm between the plunger
and the mechanical valve.
3. Check that the LED for the plunger return sensor lights up in this state.
