The pins are spring-loaded and should retract until the pin head is nearly flush with
the surface of the pipette head. The tip of each pin, which is hidden within the pipette
head housing, has a semi-circle-shaped locking mechanism that aligns with a dowel
inside the pipette head to lock the pin in the retracted position.
If you apply too much force when pressing down or rotating the pin to retract it,
the locking mechanism at the tip of the pin can bend or break. A damaged pin
cannot lock in the retracted position. Use only gentle pressure to push down and
rotate the pin to lock it into place.
To retract the tip box stripper pins:
1
Place the pipette head upside down on a stable surface, so that the barrels are
facing up and the front of the pipette head is facing you as the following figure
shows.
If directional arrows appear on the pins, gently rotate the pins so that the arrows
are facing you.
