Handling instructions and precautions
●Attaching and detaching tubes
①Confirm 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.
②When connecting tubes, if you do not insert the tube all the
way to the tube end, it may result in leaks.
③After installing the tube, pull on it to check that it does not
come off.
④Do not meaninglessly press on the release ring before
attaching a tube. Doing so may cause the tube to become
detached.
Precautions for removing tubes
①Before removing tubing, be sure to confirm that the pressure
inside the tubing is zero.
②Uniformly 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.
Tube end
Precautions for mounting fitting Precautions for attaching tubes
①Use the appropriate tool to tighten the hex nuts on the fitting.
②Refer 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
①Use the appropriate tool to remove the hex nuts from the
fitting.
②Remove 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
①Attaching 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
sleeve for sealing the tube
periphery.
②Removing 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.

If removing pipes is difficult because the piping space is very
constricted, consult your nearest Koganei sales office for a
specialized tool that is available.
Specialized tools for removing tubes
Handling instructions and precautions
●Usable tubes
Use of both nylon tubing and urethane tubing are supported.
Nylon tubing outside diameter precision should be within ±0.1
mm [±0.004 in] (nominal) for nylon tubing and within ±0.15 mm
[±0.006 in] (nominal) for urethane tubing. Use tubing with ovality
(difference between major axis and minor axis) within 0.2 mm
[0.008 in] (use of Koganei tubing is recommended). Use of tubing
that is not a Koganei genuine product or a compatible
(recommended) product may result in tube disconnection, air
leakage, or other problems. Be sure to check on tubing before
building a pneumatic system. Also, note that you cannot use the
conductive urethane tube U2A-B produced by Koganei.

NOTE
1. Use tubing with an exterior that is not damaged. If tubing
becomes damaged after repeated use, cut off the
damaged portion.
2. Do not allow tubing to become severely bent or twisted
near the connection to a fitting. Such a condition creates
the risk of air leakage. The table below shows minimum
radius guidelines for nylon and urethane tubing.
3. Do not use extremely soft tubing, which causes a severe
drop in pull-out strength.
4. Before removing any tubes, always turn off the air supply.
Also, be sure to confirm that the air inside the pipes is
completely vented before starting.
●Speed adjustment for actuators
①To increase the speed
Start with the needle of the speed
controller fully closed and turn it
counterclockwise to increase the
speed of the actuator. When you
reach the desired speed, be sure
to tighten the lock nut so that the
speed setting does not deviate.
②To decrease the speed
If you turn the needle of the speed
controller too far (the speed is too
fast), turn it clockwise to decrease
the speed. When you reach the
desired speed, be sure to tighten
the lock nut so that the speed
setting does not deviate.
