Before beginning to pave with bituminous materials, the screed
should be preheated. This helps to prevent the hot mix from sticking
to a cold screed plate, and produces a smooth, tight mat surface.
Preheating should be performed if the machine sets a long period
of time between loads allowing the screed plate to cool. At the
beginning of the day allow 15 minutes for heat up of a cold screed.
Shorter periods of time will be sufficient when the screed is sitting
on warm material. When heating the screed, the extensions should be
retracted full in to insure proper heating of the extension wear
plate.
IMPORTANT: Avoid overheating of the screed which may
warp the screed wear plate and frame.
Never refuel paver with screed heaters lit and operating.
Never use the wash down system when the screed heaters
are lit or operating.
Do not open propane valves to the screed burners unless flame is
present to light the burners. An accumulation of unburned gas could
result in explosion. Do not allow smoking when lighting propane fired
screed burners. If screed heaters should go out for any reason, never
attempt to relight until excess propane is ventilated from the screed
burner chamber.
Failure to observe the above could result in fire, personal
injury or death!!!
To light the screed heaters, turn the valve on top of the propane
tank. Adjust the pressure valve until the gage reads between six and
eight psi. Hold an open flame next to the holes in one of the burner
nozzles and open the burner valve. Repeat the previous steps to light
the opposite burner.
the screed extensions and may be used in two different ways. When not
paving adjacent of previously paved areas, the strike off shoes should
be free floating. Loosen the jam nuts on the outer most hex head
bolts, and rotate the bolts counter clockwise until the strike off
