2. If you use a 3-position valve with closed center
to maintain a cylinder position, accuracy
and precise stop position may be difcult to
achieve because of the compressed air com-
pressibility and a valve with zero-leakage can
not be guaranteed. This is of particular impor-
tance if the valve will hold a cylinder positioned
in a xed position for a long time. Contact SMC
if necessary.
3. Ensure the cylinder is always equipped with
throttle valves to set the appropriate work
speed and that these are adjusted carefully.
Installing compressed air
actuators
• DANGeR!
1. Do not pressurize the actuator until it is mount-
ed properly and with the necessary mounting
components.
2. If a manual is supplied with the product, use
the product after you read the manual and un-
derstand its meaning.
3. Ensure that ttings and tubing to and from the
actuator are not damaged or clogged by dirt or
debris, which can cause abnormal Function.
Lubrication
• CAutIoN!
1. Cylinders designed for operation without lu-
bricating oil, are lubricated at the factory and
it is not necessary to further add lubricant. If
for some reason it still will be necessary to
lubricate, oil of class ISO VG32 should be
used. Started lubrication must be followed by
continuous lubrication during its entire lifetime,
otherwise there is risk for malfuction.
Air feed
• CAutIoN!
1. Always use clean compressed air. If the air is
polluted by chemical substances, or other type
of substances harmful for the cylinder compo-
nent parts, this may cause a malfuction.
2. Always use a lter on the direct supply line to
prevent dirt and other contaminants from en-
tering the valve and cylinder. The lter ltration
rate should be 10 µm or according to the valve
specications.
3. Install water removal equipment if the moisture
in the air is soo high that a lter isn’t enough.
This can be an after cooler or an air dryer.
4. Do not feed air whose temperature is outside
the cylinder’s intended operating range. This
also applies product ambient temperature. If
the media or the ambient temperature is be-
low -5°C, air moisture content freezes with a
malfuction as a result. Contact SMC if more in-
formation on the product’s resistance to high or
low temperature is required, or for suggestions
for actions at too high moisture content in the
air.
Surroundings
• WARNING!
1. Do not use the actuator in a surrounding that
can be harmful for the actuator. Corrosive
gases, caustic substances, salt water are ex-
amples that can effect the cylinder Function.
Ensure that the materials in the actuator are
resistant against the actual surrounding. If in
doubt, contact SMC.
