Warning
(7)Do not use tools such as pliers to rotate the
knob.
It can cause idle rotation of the knob or
damage.
(8) Verify the air flow direction.
Mounting backward is dangerous, because the
speed adjustment needle will not work and the
actuator may lurch suddenly.
(9)Adjust the speed by opening the needle
slowly from the fully closed state.
Loose needle valves may cause unexpected
sudden actuator lurching.
When a needle valve is turned clockwise, it is
closed and cylinder speed decreases. When a
needle valve is turned counterclockwise, it is
open and cylinder speed increases.
(10)Do not apply excessive force or shock to
the body or fittings with an impact tool.
It can cause damage or air leakage.
(11)For handling One-touch fittings, refer to
the Fittings and Tubing Precautions.
(12)To install/remove the product, use an
appropriate wrench to tighten/loosen at
the supplied nut on Body B.
Do not apply torque at other points as the
product may be damaged. Rotate Body A
manually for positioning after installation.
(13) When performing the piping work,
turn the tightening tool in the horizontal
direction to the hexagon across flats of the
body B so that any moment is not applied to
the body. If the tool is in contact with the body
A, this may cause the body A to come off.

Note) Excessive tightening may damage the
thread portion or deform the gasket and cause
air leakage. If the screw is too shallowly
screwed in, it may come loose or air may leak.
②Chamfered area for female thread
In compliance with ISO 16030 (air pressure
