(e)
Open hydraulic pump access covers (4).
Set pump control levers (5) to PUMP position, open vent valves (6) and operate pump using pump handle

Raise ramp sufficiently to allow proper grounding.
When ramp (3) is raised sufficiently, the bridge centerline crew pulls the bays shoreward, and tightens an-
choring lines and lowers ramp bay.
Set pump control levers (5) to traffic position; close vent valves (6), and close covers (4).
NOTE
When installing near shore end span use transporter to pull near shore end span an additional 10 ft (3
