Operation
Set the Screed Extension, Flight
Screw and Endgate
Use the screed extensions when paving widths
exceeding eight (8) feet. The screed extensions should
be heated before making any adjustments. Use the
wrench provided to make adjustments. When adjusted
correctly, pressure on the rear edge of the extended
screed is the same as the rear edge of the main screed,
resulting in a smooth mat the length of the screed.

You can extend or retract the screed extension using
the extension switch on the control panel. (Pages 3-6
to 3-11) A remote control box is also provided on both
sides of the paver with switches to extend or retract the
screed, along with turning the auger on and off while
paving. (Figure 4-44) If equipped with the optional
sloping extensions, an additional switch for this feature
is also located on the remote control box.
Electric Flight Screw
The electric ight screw is an added convenience to the
operator for making automatic, minor adjustments to mat
thickness while paving. (Figure 4-41) A screed height
gauge is located on both sides of the paver to provide
the operator with a quick reference to the location of the
electric screw.
