Specific Product Precautions
Be sure to read this before handling the products. For safety instructions, refer to the “Handling Precautions
for SMC Products” and the “Operation Manual” on the SMC website: http://www.smcworld.com
Handling Precautions
Warning
Caution
1.Affix a safety cover in places where there is a
danger of personal injury.
A large gripping force is generated during clamping. If there is
a possible pinching hazard, design the structure to avoid
contact with the human body.
4.Make sure that the offset of the clamping position is
within ±15 mm as shown in the figure below.
Allowable offset
±15 mm
Caution
1.Avoid using material handling equipment in a way
that applies torsion, inertial force, or impact.
2.Use the product under air pressure of up to 0.49 MPa.
3.Make sure that the clamp arm length is not longer
than the lengths shown below.
