Precautions
1. Do not supply air until the cylinder is fi xed with the attached bolt.
2. If air is supplied without securing the cylinder, the cylinder could lurch, 
posing the risk of bodily injury or damage to the peripheral equipment.

Note)
2) 1st stage 
(A stroke operation)
When the air pressure 
is supplied from the        
port, the rod operates 
the A 
stroke.
3) 2nd stage 
(B-A stroke operation)
Following the 1st stage, 
when the air pressure 
is supplied from the    
port, the rod operates 
the B-A stroke.
4)  Cylinder retraction 
When the air pressure 
is supplied from the     
port, the rod retracts 
completely.
2) Double output 
When the air pressure 
is supplied to the    
and   ports at the 
same time, the double 
output can be obtained 
in the A stroke range.
2) Operation 
When the air pressure 
is supplied from 
the    port, the rod 
operates the A stroke.
2) Operation 
When the air pressure 
is supplied from 
the    port, the rod 
operates the B stroke.
