Screed Travel Lock Valve. This valve is used to
lock the screed in the raised position. Turning the valve
clockwise to the closed position will lock the screed in its
current position. To lower the screed, set the screed lift

using the valve, but the ignition switch must be in the ON
position.
NOTE
With the screed travel lock valve
closed, the screed can be raised, but
not lowered.
