4-26 LeeBoy 6150 Conveyor Paver
Operation
Set the Screed Extension, Flight
Screw and Endgate
Use the screed extensions when paving widths exceed-
ing eight (8) feet. (Figure 4-54) The screed exten-
sions should be heated before making any adjustments
using the wrench provided. Try to balance the width of
extensions so that forces against each extension are
equal. For example, if you need a total of three feet of
extension, extend the left and right extensions an equal
amount--one foot and six inches--on each side.
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. Keeping a consistent paving speed and limiting
stops keeps the screed uniform and produces a higher-
quality mat (most mat defects occur where a paver is
stopped).

NOTE: To set the depth, you can place small starter
blocks under the main screed while you make
adjustments. (Figure 4-55)

Tow Point Cylinders
The tow point cylinders are an added convenience
to the operator for adjusting the depth of the screed.
Where the screed pull arms connect to the paver tractor
is called the tow point. Tow point cylinders are placed in
a oat mode when paving without restricting the screed
from moving independently of the tractor. This feature
makes it possible to lay down an asphalt mat of uniformly
desired thickness while maintaining a consistent line-
of-pull. They can be used to make minor adjustments to
the depth or thickness of the mat when paving manually.
A tow point cylinder gauge is located on both sides of
the LeeBoy 6150 Conveyor Paver. (Figure 4-53)

1. Before paving, center the tow point by referring
to the screed elevation gauge on each side of the
paver.
2. Raise or lower the tow point until the rod end is ush
with the “0” on the indicator using the left and/or
right tow switches on the main control panel.
3. While paving, refer to both gauges and make
minor adjustments to the screed using tow point
adjustments as needed.
