4-22 LeeBoy 8515D Conveyor Paver
Operation
Hopper Wings
The hopper wings are hydraulically opened so the
hopper can be filled with paving material.
(Figure 4-38)
Conveyor paddles in the bottom move the asphalt back
to the auger, where the mix flows through the cut-off
gates to the screed.
To operate the hopper wings:
1. Push the hopper wings switch to OUT on the
operator control panel to fold out hopper wings.
(Pages 3-6 to 3-11)
2. Be sure the hopper wings are completely extended
before receiving paving material from the truck.
3. Push the hopper wings switch to IN to close the
hopper wings.
DO NOT fold in the hopper wings when
the hopper is full of asphalt. DO NOT fold in the
hopper until the material truck has moved completely
away from the paver. Never raise the conveyor bed
with asphalt in the hopper.

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.
Running the engine 2200 RPMs
to heat the screed provides the best operating
conditions. Running the engine at lower RPMs
will not allow the screed to heat correctly and may
damage the generator.
To operate the electrtic screed heating system:
1. Start the paver and idle until the engine reaches
normal operating temperature.
2. Set the throttle to normal operating speed (1800 to
2200 RPMs).
3. Raise the screed plate one or two inches off the
ground.

4. Turn the electric heat control box power ON by
flipping the power switch up. (Figure 4-37)
5. Press the Start Heat button.
6. The HEAT ON indicator light will illuminate and stay
on as long as the element is heating the screed.
(The factory-set heat cycle is 20 minutes, which
should generate enough heat to begin the paving
process. Operating in cold temperatures may affect
the screed plate temperature slightly.)
7. If the heat cycle has completed but the screed
plates still require heating, restart the cycle by
repeating Step 4.
