5. Operating method or operation
5-1. Precautions for Design
！
Warning
1.The product is designed for use only in compressed air systems. Do not operate at pressures or
temperatures, etc., beyond the range of the specifications, as this can cause damage or malfunction
of the cylinder and other equipment. (Refer to the specifications.)
Please contact SMC if using fluids other than compressed air. The product cannot be guaranteed if
is used outside of the specification range.
2.Take safety measures (e.g. mounting protective covers) when there is a danger of fingers being
caught in a gripper or workpieces causing damage, etc.
3.There is a danger of workpieces dropping if there is a decrease in gripping force due to a drop in
circuit pressure caused by a power failure, etc. It is necessary to take measures such as drop
prevention so that injury and damage to machinery or equipment can be prevented.
4. If the product is used for a purpose other than the transportation of a workpiece such as positioning
or clamping, please consult SMC.
！
Caution
1. Finite orbit type guide is used in the actuator finger part. By using this, when there are inertial force
which cause by movements or rotation to the actuator, steel ball will move to one side and this will
cause a large resistance degrade the accuracy. When there are inertial force which cause by
movements or rotation to the actuator, operate the finger to full stroke.
5-2. Air supply
！
Warning
1. Please contact SMC when using the product in applications other than with compressed air.
2. Compressed air containing a large amount of drainage can cause the malfunction of pneumatic
equipment. An air dryer or water separator should be installed upstream from filters.
3. If condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and allow
the condensation to enter the compressed air lines. This causes the malfunction of pneumatic
equipment. If the drain bowl is difficult to check and remove, the installation of a drain bowl with an
auto drain option is recommended.
4. Use clean air.
Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or
corrosive gases, etc., as it can cause damage or malfunction of equipment.
For detailed information regarding the quality of the compressed air described above, refer to
SMC's "Air Cleaning Systems".
！
Caution
1. When dry air is used as the fluid, degradation of the lubrication properties inside the equipment
may occur, resulting in reduced reliability (or reduced service life) of the equipment. Please
consult with SMC.
2. Install air filters.
Install
an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5μm
or finer.
