3.4 Piping
Caution
• Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
• When installing piping or fittings, ensure sealant material does not enter
inside the port. When using seal tape, leave 1 thread exposed on the
end of the pipe/fitting.
• Tighten fittings to the specified tightening torque.
• Tubing
Connect a tube (applicable tube O.D. Ø6) to the air pressure supply
(P) port.
To remove the tube, push the release button and pull out the tube.

3.6 Environment
Warning
• Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
• Do not use in an explosive atmosphere.
• Do not expose to direct sunlight. Use a suitable protective cover.
• Do not install in a location subject to vibration or impact in excess of the
product's specifications.
• Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product's specifications.

6 Maintenance
Implement the maintenance and check shown below in order to use the
vacuum gripper safely and in an appropriate way for a long period of
time.
6.1 Maintenance for vacuum gripper
Caution
• Check before and after the maintenance work
When the product is to be removed, turn off the power supply, and be
sure to cut off the supply pressure and exhaust the compressed air.
Confirm that the air is released to atmosphere. When mounting the
product after the maintenance work, supply compressed air, connect to
the power, check if it functions properly and have a leakage inspection.
• Maintenance should be performed according to the procedure
indicated in the Operation Manual.
Improper handling can cause damage and malfunction of equipment and
machinery.
• Maintenance work
Compressed air can be dangerous when handled incorrectly. Therefore,
in addition to observing the product specifications, replacement of
silencer and other maintenance activities should be performed by
personnel with sufficient knowledge and experience pertaining to
pneumatic equipment.
• Draining
Remove condensate from air filters and mist separators regularly. If the
collected drainage is drained to the downstream side, it can stick inside
of the product, causing operation failure and failure to reach the specified
vacuum pressure.
• Replace the silencer built into the vacuum gripper regularly.
It is recommended to replace the silencer when the pressure drop
reaches 5kPa as a guideline. The replacement cycle varies depending
on the operating conditions, operating environment and supply air quality.
However, if there is a vacuum pressure drop and/or delay in the vacuum
(gripping) response time which causes problem with the settings during
operation, stop the operation of the product and replace the silencer
regardless of the above mentioned replacement guideline.
● Part number for the silencer assembly for replacement:
ZX1-HS1
● Silencer assembly replacement procedure
- Remove the cover.
- Loosen the 2 cross-recessed pan head screws to remove the
silencer assembly.
- Assemble the new silencer assembly.
- Mount the cover.

● Do not disassemble or modify the product, other than the
replacement parts specified in the operation manual.
6 Maintenance - continued
6.2 Maintenance for suction cup
Caution
● Suction cups are disposable. Replace them on a regular basis.
Continued use of suction cups will cause wear and tear on the gripping
surface, and the exterior dimensions will gradually get smaller and
smaller. As the cups' diameter gets smaller, their lifting force will
decrease, though gripping will still remain possible.
It is extremely difficult to provide advice on the frequency of suction
cup replacement. This is because there are numerous factors at work,
including surface roughness, operating environment (temperature,
humidity, ozone, solvents, etc.), and operating conditions (vacuum
pressure, workpiece weight, pressing force of the suction cups on the
workpieces, presence or absence of a buffer, etc.). The weakening of
bent parts or the wear or sticking of rubber parts may occur with the
bellows type cup.
The customer should decide when suction cups should be replaced,
based on their condition at the time of initial use. The bolts may
become loose depending on the operating conditions and environment.
Ensure the maintenance is performed regularly.
● Replacement of the suction cup
- Pull the lock ring upward, and, after lifting it up to the adapter, remove
the old cup by pulling it downward.
- While holding the lock ring in the raised position place a new cup onto
the adapter.
- Confirm that the cup is securely in place, and then return the lock ring
to its original position.
Note) The cup without lock ring is just inserted to the end of the
adapter.

7 Limitations of Use
7.1 Limited warranty and disclaimer/compliance requirements
Refer to Handling Precautions for SMC Products.
Caution
Exhaust Noise
When vacuum ejector generates vacuum, noise can be heard from the
exhaust port when the standard supply pressure is close to the pressure
that generates peak vacuum pressure making vacuum pressure unstable.
If the vacuum pressure range is adequate for gripping, there should not
be a problem. If the noise causes a problem or affects the setting of the
pressure switch, change the supply pressure slightly to avoid the
pressure range of the noise.
