Retracting the tip-box stripper pins
AssayMAP Bravo Platform Installation Guide
Figure Bravo 96AM Head with tip-box stripper pins retracted (left) and extended (right)
CAUTION
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 Bravo 96AM Head upside down on a stable surface, so that the
probes are facing up and the front of the 96AM Head (logo side) is facing
you.
If directional arrows appear on the pins, gently rotate the pins so that the
arrows are facing you.
2
Insert the end of a 2- mm hex wrench into the head of one of the pins, and
very gently push the pin down into the pipette head until you feel the pin
stop.
Verify that the pin is properly seated. If the pin has an arrow, the square
end of the arrow should disappear or be barely visible.
IMPORTANT
If the pin hits a stop before it retracts completely, the pin
locking mechanism is above instead of below the locking dowel. While
removing any downward pressure on the pin head, gently rotate the pin
in quarter- turn increments until you feel the pin drop into the seated
position.
3
When the pin is properly seated, rotate it counterclockwise no more than
°
180 until it locks.
4
Repeat this procedure for the other pins.
