      Important Safety Precautions

 

 

WARNING

 

Failure  to  follow  the  safety  precautions  below  could  result  in 

serious injury or death.

 

 

 

 

Do not modify the cylinder.

 

・

 

Doing so may damage the cylinder and cause oil leakage which could result in a fire. 

And if the hydraulic oil leaks, the gripping force of the chuck will lower and the work may fly 

out, which is dangerous. 

・

 

Do not attach additional machining such as screws. 

・

 

Do not detach parts of the cylinder from the cylinder. 

 

 

 

 

Do not rotate the cylinder without hydraulic pressure.

 

・

 

Doing so could cause seizing inside the cylinder, leading to a drop in the gripping force of 

the chuck. This is dangerous as work will fly out. 

 

 

 

Periodically add hydraulic oil. 

Turn off power and use designated hydraulic oil. (Refer to page 19) 

 

 

・

 

If supplying of the hydraulic oil is insufficient, the operation speed may lower and the thrust 

force will become insufficient resulting in a drop in the gripping force of the chuck, which is 

dangerous as the work may fly out. 

・

 

Use abrasion resistant and deforming hydraulic oil.
