Operation
Mat Texture AdjustmentMat Texture Adjustment
There are three adjusters in each screed extension,
however the adjusters at each end are preset by the
dealer and do not need adjustment.
Adjust the mat texture using the Angle-of-Attack (AOA)
adjustment screw in the center to produce a smoother
or coarser mat texture. (Figure 4-80)
• The screed extension should be hot before making
any adjustments.
• Spray the bottom of the screed with cleaning solvent
BEFORE heating the screed.
NEVER spray cleaning solvent or
release agent on or near a hot screed heating or near
open ame. Cleaning solvent and release agents are
ammable and could cause serious personal injury.
NOTE: Do not allow release agent chemicals to run
onto the ground.
AOA
Figure 4-80. AOA Adjustment
To make the AOA adjustment:
1. Spray down and heat screed extension if needed.
2. Turn the AOA adjuster in the direction for desired
result:
• Turning the AOA adjuster counterclockwise
will increase the pressure on the back of the
extension, which gives a smoother, slicker nish.
• Turning the adjusters clockwise will decrease
the pressure on the back of the extension,
resulting in a coarser nish.
NOTE: Too much pressure on the back of the screed
extension will take the weight off the screed
wearplate and cause poor material compac-
tion, resulting in a poor nish.
Unloading and Loading
Ensure the transport trailer has the capacity to carry
the paver’s weight. Park the trailer in a clear, level area
when loading or unloading the machine.
ALWAYS position an assistant to be a
ground guide when loading and unloading the paver.
Work slowly and carefully to avoid
accidents. Keep the loading area clear.
ALWAYS back the paver up loading
ramp with the screed end rst. ALWAYS be alert to
uneven surfaces and the potential reactions when
transferring the paver from surface to surface.
Serious injury or even death can result.
Use extra caution steering when
loading and unloading the paver as slight steering
changes on ramps and trailers can cause the ma-
chine to fall off the ramp or transport trailer. Serious
injury or even death can result.
