Caution
1. Fix 'Socket' square width across flats in the piston rod point with the spanner etc. , prevent
the piston rod from rotating, and tighten the screw tightening when work piece or jig, etc.
are installed properly by the torque value within the range of the limitation.
It causes the abnormal reaction of an auto switch, the space of an internal guide, and an increase
of the sliding resistance, etc..
2. When mounting the workpiece or other device to the actuator tighten the fixing screws
with adequate torque within the specified torque range.
Tightening the screws with a higher torque than the maximum may cause malfunction, whilst
tightening with a lower torque can cause the displacement of the mounting position or in extreme
conditions detaching of the work piece.
