Install Adjustment Screw/Cap

9.Loosely install hex nut and adjustment cap onto the air cylinder shaft.

Adjust the Adjustment Screw/Cap

10.Push the drive block forward until resistance is felt when it engages the cylinder. Make sure the resis- tance is not due to shock absorber contact with the adjustment screw or adjustment cap.

11.Adjust the adjustment screw or adjustment cap until it contacts the shock absorber.

12.Hold the adjustment cap in place and tighten the hex nut against the adjustment cap.

Prepare Machine for Operation

13. Open the ball valve to pressurized the system.

Adjust Shock Resistance

14.Execute a shot to see how the shock absorber affects the speed of the drive block.

15.The shock absorber has a numeric scale on one side. Rotate the knob with the scale to a higher value for more resistance. Rotate the knob to a lower value for less resistance.

16.Repeat these steps until the desired resistance is achieved.
