flow will usually provide a correct setting. The Pinch Stop Screw is now correctly set up to

provide the minimal wear and tear on the Tube.

After adjusting the Pinch Stop Screw (Figure 5, K), loosen the Locking Nut (Figure 5, B) and

turn the Piston Stop Screw (Figure 5, C) clockwise until you feel resistance. The resistance

you feel is the Piston Adjustment Screw pressing against the Piston (Figure 5, A). The Pinch

Stop Screw is now set to a closed position.

Note: You may cut the tubing if you tighten the Piston Adjustment Screw (I) too much.

To set the Piston (Figure 5, A) to the desired amount of opening, turn the Piston Stop

Screw (Figure 5, C) counter-clockwise from the closed position as described above. Once

the desired amount of opening is reached, retighten the Locking Nut (Figure 5, B).

Note: One full turn of the Piston Stop Screw (Figure 5, C) equals 0.042 inches

[0.1 cm] of travel.
