Gap Adjustment for Head Unit
Mechanical Valve and Plunger
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]
Loosen the cap screws (2 pcs, C3 x 6)
on the mounting bracket for plunger.
Move the bracket back and forth to
match the axis centers of the
mechanical valve and the plunger.
While matching the axis center in
height direction, fasten the cap screws
(2 pcs, C3 x 6) to fix the bracket.
