Caution
！
Be certain to align the rod axis with the load and direction of movement

when connecting.
When not properly aligned, the rod and tube may be twisted, and damage may be caused due
to wear on areas such as the inner tube surface, bushings, rod surface and seals.
When an external guide is used, connect the rod end and the load in such a

way that there is no interference at any point within the stroke.
Do not scratch or gouge the sliding parts of the cylinder tube or piston rod,

etc., by striking or grasping them with other objects.
Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may
cause malfunction. Also, scratches or gouges, etc., in the piston rod may lead to damaged
seals and cause air leakage.
Prevent the seizure of rotating parts.

Prevent the seizure of rotating parts (pins, etc.) by applying grease.
Do not use until you can verify that equipment can operate properly.

Verify correct mounting by function and leak tests properly after compressed air and power are
connected following mounting or repair.
Cantilever fastening

If a cylinder is actuated at high speed when mounted with one side fastened and one side free
(basic type, flange type, direct mount type), the bending moment may act on the cylinder due
to vibration at the stroke end, causing damage to the cylinder. In such cases, install a mounting
bracket to suppress vibration of the cylinder body, or reduce piston speed until the cylinder
body does not vibrate at the stroke end. Also, use a mounting bracket when moving the cylinder
body, or mounting a long stroke cylinder horizontally with one-sided fastening.
