8. Place the ramp in front of the starter so that the outside flanges
align with the truck rails inside the cell. Insert the front flanges
of the ramp over the edge at the bottom of the lower cell.
Check that the ramp will not slide left to right or front to back to
ensure that it is properly positioned. See
Figure 42. Insert truck ramp flanges over the cell bottom.
9. The truck is now ready to remove. With both hands on the
pull bar at the front of the truck, pull the truck forward. With
thumbs on the truck top surface and fingers under the Power
Pole handles, keep both hands on the pull handles as the truck
travels down the ramp, and brace against the truck to control
the speed. The stab connections from truck to starter bus will
present some initial resistance. See
and
Figure 43. Use Power Pole handles to pull out truck.

With the SCR truck disconnected and removed from the RVSS
cabinet, the Starter can still be operated in Emergency Bypass full-
voltage starting mode (using Normal/Bypass switch SS2) if needed.
It will not be necessary to make any cabling changes, since the
Bypass contactor remains in place in the lower cell.
