Loosen the jam nuts on the two vertical five inch long all thread
hex head bolts, and rotate the bolts clockwise until maximum vertical
movement of the screed strike off shoe is available. Retighten the jam
nuts to secure the long hex head bolts. The screed strike off shoes
are now full floating, and will maintain a positive edge of the mat at
any paving depth.
When paving next to a previously paved area, if a smooth joint is
to be made, the screed strike off shoe on the side where the joint is
being made should be adjusted so that it is level with the bottom of
the screed wear plate and secured. To secure the screed strike off
shoe, simply reverse the steps described previously to make the shoe
full floating.
Set tailgate chains on truck to desired opening of the tailgate.
Raise the truck bed sufficently to dump into the paver hopper. Engage
the augers at this time in the "Automatic" position. Open gates
sufficently to allow material to the augers. It is not necessary to
open the gates to full open position. The augers are visible from the
rear of the machine and a constant check on material in front of the
screed can be observed continuously. This will be very helpful when
operation of the augers is in the "Manual" position. When the augers
are operating in the "Automatic" position, the augers will engage and
disengage when the material flow is needed.
Move the paver forward four or five feet and stop at this point.
Check the thickness of the pad. This will allow time for the screed
extensions to warm up properly to provide for a smoother mat finish.
When you approach the end of the paving pass, observe the augers
and the amount of material in front of the screed. Within a short
timr the operator will be able to close the gates, and control the
amount of material in front of the screed to match within a few inches
of the previous mat. No tailing of the pad and virtually all clean up
at the end of the pad is eliminated.
Hook the screed lift chain in the tailgate hook and raise the
rear of the paver off the pad. Caution should be taken when
approaching the end of the pass to minimize the amount of materia in thel
hopper. This will make it easier to maneuver the machine to the next pass.
If the width of the required pass is less than eight feet, the
pull can be lapped over the previous pull. The screed on the lapped
side of the paver is to be set on "0" and the screed extension fully
retracted. The compaction of the screed should erase any marks in the
asphalt mat.
shoe will move easily. Retighten the jam nuts to secure the hex head
bolts.
