Part Number Description

F4015065 5 x 1 mL piston noses and mounting tool.

F4015005 1 nose mounting tool.

Piston rod

Piston nose

Piston nose holding tool

You need the special tool for mounting the piston nose on the 1 mL piston. The nose push-fits onto the piston shaft.

1.Remove the syringe from the pump as described page 6-4.

2.Slide the piston out of the syringe barrel.

3.Remove the piston nose from the piston rod by carefully pinching the piston nose with a pair of cutters and gently pulling the piston nose off the piston rod. Take care not to damage the end of the piston rod when removing the piston nose.

4.Remove any remaining debris of the original nose from the end of the piston rod.

5.Put the new piston nose in its recess in the piston nose holding tool.

6.Turn the tool upside down and place the piston assembly.

7.Press the piston shaft firmly into the piston nose holding tool. A slight rotation of the piston shaft ensures a correct fitting.

8.Slacken the piston button Allen screw and remove the piston button from the piston rod.

9.Remove the tool from the piston assembly.

10.Dip the piston nose in distilled water and slide the piston into the syringe.

11.Hold the syringe upright with the threaded end of the syringe resting on a flat, clean surface. Slide the piston into the syringe until the piston stops (the nose is level with the end of the syringe).

12.Slide the piston button against the body of the syringe and tighten the Allen screw that secures the piston button onto the piston rod.

13.Slide the piston up and down in the syringe five or six times to ensure a smooth operation be- tween the piston and syringe.

14.Remount the syringe on the pump as described page 6-4.
