2. Operating method or operation

2-1. Design precautions

！
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 specifications, as this can cause
damage or malfunction. (Refer to the specifications.)
Please contact SMC if using for fluids other than compressed air. We do not guarantee
against any damage if the product is used outside of the specification.
2. Take safety measures (e.g. mounting protective covers) when workpieces pose a danger
of fingers being caught in a gripper, 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 euqipment can be
prevented.
4. If the product is used for the purpose other than the transportation of a workpiece such as
positioning or clamping, please consult SMC.

2-2. Selection

！
Warning
1. The gripping point should be set within the limited range.
When the gripping point distance becomes large, the gripper attachment applies an
excessively large load to the gripper sliding section, and causes adverse affects on the
life of the gripper. Refer to the catalog for details.

point
Good : "L" and "H" are appropriate
2. Attachments should be designed to be as light and short as possible.
(1) A long or heavy attachment increases the inertia force required to open or close the
fingers. This may cause unsteady movement of fingers and have an adverse affect on
the life of the gripper.
(2) Design the attachment as short and light as possible even if the gripping point is
within the limited range. Refer to the catalog for details.
(3) Select a larger size gripper or used two or more grippers for handling a long and/or
large workpiece.
