LeeBoy 8510E Conveyor Paver 4-23
Operation
Electric Screed Heat (Option)
The LeeBoy 8510E Conveyor Paver offers an optional
Electric Heat system to heat the screed, including the
screed extensions, in lieu of the propane burner system.
A hydraulically-driven generator powers the electric
heat control box mounted in the center on the rear side
of the machine. This control box is where you will select
the heating function before you begin to pave.
(Figure
4-38)
A hydraulically-driven generator provides power to the
electric heat control box mounted in the center on the
rear side of the machine. The electric heat box is pre-
wired for the heated endgates option. If not equipped
with this option, the left and right endgate switches do
not function.

Once the heating function has been enabled, the
distribution/control box will apply electrical power to the
heating elements and the heating cycle will begin. The
heating cycle is timed to optimize the heat generated at
the screed plates.
When using the screed extension(s), light the screed
extension(s) after the main screed burner has been lit
following these additional steps
(Figure 4-37) :
5. Lift up on the burner coupler to release ignitor.
6. Lift ignitor wand, turn valve counterclockwise to
the OPEN position and light the ignitor end with the
torch striker.
7. Replace the lit ignitor wand into the burner cradle.
8. Push down on burner coupler back into place.

NOTE: Adjust the pressure regulator valve IN or OUT
until the propane pressure regulator gauge
reads 15 pounds.
NOT E: It may be necessary to maintain low heat on
the screed if paving on a cool, windy day.
Reduce pressure on the propane pressure
regulator gauge to two pounds (.14 bar) in
these conditions. DO NOT attempt to regulate
the burner with the burner valve.
After the main screed (and screed extension) has
heated for 15 minutes:
1. Turn the propane tank valve clockwise to the
CLOSE position to allow the propane system to
burn off all the gas.
(Figure 4-35)
2. When the flames extinguish, TURN OFF ALL burner
valves clockwise to the OFF position. (Figures
4-34 through 4-36)
