WARNING
Do not touch electrical wiring connections (bare live parts) of actuators equipped with
solenoid valves, actuators equipped with switches, and other such actuators.
Do not touch live parts with bare hands.
An electric shock may occur.
Turn off the power, release the residual pressure and make sure that there is no residual
pressure before disassembling or inspecting the actuator.
CAUTION
Plan and perform daily and periodic inspections so that maintenance can be managed
properly.
If maintenance is not properly managed, the product's functions may deteriorate significantly and
this may lead to faults (such as short service life, damage, and malfunction) or accidents
.
