Warning
(5) After pushing the knob down to lock,
confirm that it is locked
Confirm that the knob is locked by pushing the
knob in after adjusting the cylinder speed. When
the speed controller is unlocked, the set flow
may change. If the knob is pulled with force
while the speed controller is unlocked, it may
result in breakage. When it is unlocked, do not
pull the knob out with force.
Lock
(6) Turn the knob slowly in the open or closed
direction during operation.
(Guide for rotation speed: 1 [rev/sec] or
below)
Scale malfunction
adjustment is made between two graduations
(for example, 0 →1→0).
(7) Do not force the knob to turn outside the
specified range indicated to the scale.
The scale may indicate a wrong value, possibly
leading to a wrong setting.
[Example of wrong use]: While the scale
indication range is 0 to 8, turning the scale in the
open direction from graduation 8 caused the
scale to indicate 0.

Warning
(9) Do not use tools such as pliers to rotate the
knob.
It can cause idle rotation of the knob or
(10) To adjust the 2
knob in the fully closed position, and then
make adjustment
counterclockwise.
Depending on the opening adjustment condition
of the knob (needle), the cylinder may suddenly
move. Adjustment of the knob (needle) in the
clockwise direction decreases the flow rate
(closes), and
counterclockwise direction increases the flow rate
(opens).
The actuator speed decreases when an
adjustment in the clockwise direction is made and
increases when
counterclockwise direction is made.
(11) Do not apply excessive force or shock to
the body or fittings with an impact tool.
It can cause damage or air leakage.
Caution
(1) Cylinder speed check
Large variations in actuator speed can occur as
a result of individual product differences due to
tolerance of the components, individual cylinder
differences, operating conditions, temperature,
etc. The final cylinder speed should be checked
each time the setting has been changed.
(2) Lifting force for the knob
The lifting force for the knob is specified as
shown in the table below.
Lifting the knob with a lifting force larger than
that specified in the table below will cause the
knob to come off, make the cylinder setting
speed or scale incorrect, or cause damage to
the product.
