INSTALLATION
These swing cylinders are designed so that you can set the radial position of the clamp
arm after mounting the cylinder. If you need to change the rotation direction, do it
before mounting the cylinder.
Changing Plunger Rotation (if needed)
Change plunger rotation by lining up the letter on top of the plunger with the arrow on
the side of the cylinder opposite the ports. To change rotation, refer to illustrations and
follow procedure below. You will need a spanner wrench for the bottom plug.
1. Position the arm (F) on the plunger (G) to provide a handle to grasp for moving the
plunger.
(a) Release the clamp arm bolt (H).
(b) Remove the retaining ring (I) and slide the clamp arm down the plunger until
the top of the arm is 6 mm (0.25 in.) from the top surface of the plunger.
(c) Tighten the clamp arm bolt. DO NOT discard the retaining ring.
2. Place spanner wrench on bottom cylinder plug (J) and turn the plug (facing you)
counter-clockwise 4 turns.
NOTE: On single-acting models, you may need to turn bottom plug more than 4 turns to
help relieve spring tension.
3. Push down on the plunger and rotate it to line up the desired letter (L, R, S) with the
arrow on the side of the cylinder.
4. Once the letter and arrow are lined up, pull the plunger up, turn the bottom plug back
in (clockwise), and tighten firmly.
