release the guide wire brake on the OAD, and retract the OAD sheath and drive
shaft, from the introducer, guide sheath, or guide catheter, while monitoring and
maintaining guide wire position.
4. Power off the OAS pump by pressing the green Start button on the OAS pump
control panel to stop saline from flowing through the saline tubing and verify that
the green LED, on the OAS pump control panel, is not illuminated.
5. Disconnect the saline tubing from the OAD currently in use and set aside for use
with the replacement OAD.
6. Obtain a new replacement OAD and carefully remove the new replacement OAD
from the package.
Note: Removal of the OAD from the packaging by tipping the tray and allowing
OAD to fall out can result in damage to the OAD or ancillary devices underneath
the OAD.

connect the new replacement OAD power cord to the OAS pump.
