Handling instructions and precautions
●
Attaching and detaching tubes
①
Confirm that the cut surface of the tube is cut straight across,
that the outer surface of the tube is not damaged, and that
the tube has not become oval shaped.
②
When connecting tubes, if you do not insert the tube all the
way to the tube end, it may result in leaks.
③
After installing the tube, pull on it to check that it does not
come off.
④
Do not meaninglessly press on the release ring before
attaching a tube. Doing so may cause the tube to become
detached.
Precautions for removing tubes
①
Before removing tubing, be sure to confirm that the pressure
inside the tubing is zero.
②
Uniformly press the release ring inwards as far as it goes
and then pull out the tubing. If you do not fully press in on the
release ring, the tube may not come out, or the tubing may
become scratched causing debris to be left inside the fitting.
The safety precautions for the speed controllers with quick
fittings are shown below. Be sure to read the material in the
front of the General Personal Catalog regarding safety
precautions other than those below.
Safety precautions (speed controllers with quick fittings)
WARNING
●
Air control direction varies depending on the product. Before
using a product, confirm the direction as noted in this
document and by identifying the product. Orienting the control
direction incorrectly creates the risk of personal injury and
machine damage.
●
When adjusting the speed of the actuator, start with the
product's needle fully closed and then gradually open it to
adjust the speed. There is a risk of the actuator popping out if
the needle is open. Note that the needle closes when turned
to the right and opens when turned to the left.
●
Do not forcibly twist or rotate products with rotating plastic
bodies. Doing so causes a risk of leakage or damage to the
body.
CAUTION
●
Speed controllers have an allowable leakage, so do not use
them if zero leakage is required.

Precautions for mounting fitting
Precautions for attaching tubes
①
Use the appropriate tool to tighten the hex nuts on the fitting.
②
Refer to the following table of recommended tightening
torques when attaching the threaded parts. If you use more
than the recommended torque when tightening the threaded
parts, you may cause leaks by fracturing the threads or
deforming the gaskets. Also, if you use less than the
recommended torque when tightening the threaded parts, it
may result in looseness or leaks.
Precautions for disconnecting fittings
①
Use the appropriate tool to remove the hex nuts from the
fitting.
②
Remove the sealant from the threads on the other parts. If
the sealant is stuck to the other parts, it may get into
peripheral devices and cause a malfunction.
NOTE
The sealant on the quick fittings can be reused multiple
times, as is. However, the sealant may stick to the threaded
parts of other devices. Be sure to clean the inside of the
female threads on the devices.

How to attach and detach tubes
①
Attaching tubes
The quick fitting speed controller
is equipped with a lock claw that
holds the tube in place when it
has been pushed all the way to
the end, and with an elastic
s l e eve fo r s e a l i n g t h e t u b e
periphery.
②
Removing tubes
When removing a tube, pressing
the release ring opens the lock
claw and the tube can be pulled
out.
Be sure to turn off the air before
removing tubes.

Mounting
●
When tightening the lock nut on a product, tighten it firmly by
hand without using a tool. The lock nut or body may be
damaged if tightened with a tool. However, if it is not firmly
tightened, the lock nut may become loose and deviate from
the initial settings.
