below. Please read them before starting to use the product.

 

 

DANGER

 

Failure to follow the safety precautions below will result 

in death or serious injuries.

 

 

 

Be  sure  to  turn  off  the  main  power  supply  when  installing,  checking, 

oiling, or replacing the gripper.

 

Also, shut down the air pressure in the work area.

 

 

During work, the robot or gripper 

could  move  abruptly  and  collide 

with your body.

 

 

After  shutting  down  the  air 

pressure, 

release 

the 

air 

pressure  remaining  inside  the 

gripper.

 

 

 

 

 

 

When installing, checking, oiling, or replacing the gripper, post a sign or 

notice, or provide a fence, and so on to notify people around the machine 

that work is in progress.

 

 

Notify people around the machine that work is in progress and take measures to keep 

people other than the operator out of the work area.

 

   

  Machine motion not predicted by a third party could cause serious danger.

 

 

 

Take  safety  measures  so  that  the  operator  is  not  injured  even  if  the 

conveyed workpiece flies out due to the reduced air pressure.

 

 

Observe 

the 

legal 

safety 

standards 

defined 

by 

each 

country,  such  as  installation  of 

safeguards  or  fall  prevention 

covers.
