Compressed air that contains a large amount of drainage can cause the malfunction of
pneumatic equipment, such as valves. Therefore, take appropriate measures to ensure air
quality, such as by providing an aftercooler, air dryer, or water separator.
4) Ensure that the fluid and ambient temperatures are within the specified range.
If the fluid temperature is 5°C or less, the moisture in the circuit could freeze, causing damage
to the seals or equipment malfunction. Therefore, take appropriate measures to prevent
freezing.
For compressed air quality, refer to the SMC Best Pneumatics No. 6 catalog.
5) Precautionary measures against condensation
Moisture condensation can occur inside pneumatic systems due to a drop in temperatures
caused by the piping or operating conditions. This can degrade or wash away grease,
resulting in a shortened service life or a malfunction.
For details, refer to the catalog “Precautionary measures against condensation in a
pneumatic system” (CAT.P-E01-11).
2-6. Operating environment
Warning
1) Do not use in an atmosphere containing corrosive gases, chemicals, sea water,
water, water steam, or where there is direct contact with any of these.
2) Do not expose the product to direct sunlight for an extended period of time.
3) Do not use in a place subject to heavy vibration and/or shock.
4) Do not mount the product in locations where it is exposed to radiant heat.
5) In dusty locations or where water or oil, etc., splash on the equipment, take
suitable measures to protect the rod.
6) A decrease in the base oil of grease may be accelerated by the properties of the
compressed air used in pneumatic equipment, the external environment,
operating conditions, etc., and the resulting drop in lubricating performance may
have an effect on the equipment’s service life.
Caution
1) Internal lubricant or the base oil of grease may seep out of the cylinder depending
on the operating conditions (an ambient temperature of 40°C or more, pressure
retention, low-frequency actuation, etc.). Take great care when a clean
environment is required.
2-7. Maintenance
Warning
1) Maintenance work
If handled improperly, compressed air can be dangerous. Assembly, handling, repair, and
element replacement of pneumatic systems should be performed by a knowledgeable and
experienced person.
2) Drain flushing
Remove drainage from air filters regularly.
3) Removal of equipment, and supply/exhaust of compressed air
Before components are removed, first confirm that measures are in place to prevent
workpieces from dropping, run-away equipment, etc. Then, cut off the supply pressure and
electric power, and exhaust all compressed air from the system using the residual pressure
release function. When machinery is restarted, proceed with caution after confirming that
appropriate measures are in place to prevent sudden movement.
