Installation
Caution
Even though the inlet pressure is within the operating pressure
range, when the piping diameter is restricted due to size reduction
of supply port (P), the flow will be insufficient. In this case, the
valve does not switch completely and the cylinder may
malfunction.
Maintenance
Caution
1. Regular inspection and tightening of the hexagon
bolts with flange is recommended at 3 months inter-
vals, to satisfy IP69K. (Recommended inspection
interval: 3 months)
For the tightening location and tightening torque, see the
exploded view of the manifold (p. 24).
2. When disassembling by removing the hexagon bolt
with flange, make sure that there is not moisture on
the outer surface of the product. If the product is
disassembled or assembled with moisture attached,
moisture may enter the inside of the manifold and
cause damage.
3. Make sure that the washers are in good condition,
in position and assembled when tightening the
hexagon bolt with flange.

Installation and removal of tubing for One-touch fittings
1) Installation of tubing
(1) Cut the tubing perpendicularly, being careful not to
damage the outside surface. Use an SMC tube cutter
TK-1, 2, 3, 5, or 6. Do not cut the tubing with pliers,
nippers, scissors, etc., otherwise the tubing will be
deformed and problems may result. Allow some extra
length in the tube.
(2) The outside diameter of the polyurethane tubing swells
when internal pressure is applied to it. Therefore, it may
be impossible to re-insert the tubing into the One-touch
fitting. Check the tubing outside diameter, and when the
accuracy of the outside diameter is +0.07 mm or larger
for ø2, +0.15 mm or larger for other sizes, re-insert it into
the One-touch fitting without cutting the tubing. When
the tubing is re-inserted into the One-touch fitting,
confirm that the tubing goes through the release button
smoothly.
(3) Grasp the tubing, and slowly push it straight (0 to 5
°
) into
the One-touch fitting until it comes to a stop.
(4) Pull the tubing back gently to make sure it has a positive
seal. Insufficient installation may cause air to leak or the
tubing to release.
As a guide for checking if the tubing is pulled out or not,
refer to the following table.

2) Removal of tubing
Use the release tool when the removal of tube is difficult
due to the tube size. Refer to page 31 for releasing tools.
(1) Push the release button flange evenly and sufficiently to
release the tube. Do not push in the tubing before
pressing the release button.
(2) Pull out the tubing while keeping the release button
depressed. If the release button is not held down
sufficiently, the tubing cannot be withdrawn.
(3) To reuse the tubing, remove the previously lodged
portion of the tubing. If the lodged portion is left on
without being removed, it may result in air leakage and
make the removal of the tubing difficult.
