1. Flushing of the inside of the pipes
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil, and
other debris from inside the pipe.
2. Tube attachment
· Take a tube having no flaws on its periphery and cut it off at
a right angle. When cutting the tube, use tube cutters TK-1,
2, 3, 5, or 6. Do not use pliers, nippers, scissors, etc. If cut-
ting is done with tools other than tube cutters, the tube may
be cut diagonally or become flattened, etc., making a secure
installation impossible, and causing problems such as the
tube pulling out after installation or air leakage. Allow some
extra length in the tube.
· Grasp the tube and push it in slowly, inserting it securely all
the way into the fitting.
· After inserting the tube, pull on it lightly to confirm that it will
not come out. If it is not installed securely all the way into the
fitting, this can cause problems such as air leakage or the
tube pulling out.
3. Tube detachment
· Push in the release button sufficiently, pushing its collar
equally around the circumference.
· Pull out the tube while holding down the release button so
that it does not come out. If the release button is not pressed
down sufficiently, there will be increased bite on the tube
and it will become more difficult to pull it out.
· When the removed tube is to be used again, cut off the por-
tion which has been chewed before reusing it. If the chewed
portion of the tube is used as is, this can cause trouble such
as air leakage or difficulty in removing the tube.
4. Other Tube Brands
When using other than SMC brand tube, confirm that the fol-
lowing specifications are satisfied with respect to the tube out-
side diameter tolerance.
· Nylon tube
within
±
0.1 mm
· Soft nylon tube
within
±
0.1 mm
· Polyurethane tube within
±
0.15 mm, within −0.2 mm
Do not use tube which do not meet these outside diameter tol-
erances. It may not be possible to connect them, or they may
cause other trouble, such as air leakage or the tube pulling out
after connection.
5. Piping
· Do not apply unnecessary forces, such as twisting, pulling,
moment loads, vibration, impact, etc., on fittings or tubing.
This will cause damage to fittings and will crush, burst, or re-
lease tubing.
· Do not lift the product by the piping after the tube is connected.
Doing so may result in damage to the One-touch tube fitting.

ucts” on the SMC website: https://www.smcworld.com

Handling
Mounting
Wiring
1.
For details on the mounting method, refer to the Op-
eration Manual.
2.
Tighten to the specified tightening torque. If the
tightening torque is exceeded, the body and the
mounting screws may break. However, insufficient
torque may cause displacement of the body and
loosening of the mounting screws.
3.
Do not drop, strike, or apply excessive impact to
this product.
Doing so may result in damage to the internal parts of
the body, solenoid valve, or auto switch. In some cas-
es, this damage may result in a malfunction.
4.
Hold the body when handling the product. Do not
pull excessively on the M8 connector cable or pinch
the cable when lifting the body. Failure to do so may
result in damage to the solenoid valve or auto
switch. In some cases, this damage may result in a
failure or malfunction.
5.
The bolts may loosen due to the operating condi-
tions and environment. Be sure to conduct mainte-
nance such as tightening the bolts periodically.
1.
Avoid repeatedly bending or stretching the M8 con-
nector cable as well as applying force to it.
2.
Do not wire while energizing the product. Doing so
may result in damage to the internal parts of the so-
lenoid valve or auto switch. In some cases, this
damage may result in a malfunction.
3.
Do not disassemble the M8 connector cable or make
any modifications, including additional machining.
Doing so may cause human injury and/or an accident.

Specific Product Precautions
Be sure to read this before handling the products. For safety instructions, actuator precautions, magnet
gripper specific product precautions, and auto switch precautions, refer to the “Handling Precautions
for SMC Products” and the “Operation Manual” on the SMC website: https://www.smcworld.com
1. If pressure is applied to the external magnet gripper
parts, there is a possibility that air will get inside the
cylinder from the rod seal section. (Example: inside
a chamber, etc.)
2. As the body magnets are built-in, do not allow close
contact with magnetic disks, magnetic cards, or
magnetic tapes. Data may be erased.
