Never spray cleaning solvent or
release agent near the screed heating element or
near open flame. These agents are highly flammable
and can ignite, causing serious personal injury.
When using, consider the environment
and DO NOT allow cleaning solvent to run onto the
ground.
Screed Electric Heat Control
The LeeBoy 8616B Conveyor Paver features a
hydraulically-driven generator that powers the electric
heat control box mounted in the center of the screed for
easy access. This control box is where you will select
the heating function before you begin to pave.
(Figure
4-11) .
NOTE: Engine speed automatically increases to
1,600 RPMs when the heat cycle is active.
To operate the screed heating system:
1. Start the paver and idle until the engine reaches
normal operating temperature.
2. Raise the screed plate one or two inches off the
ground.
Figure 4-11. Electric Heat Control Box
3. Turn the electric heat control box power ON by
flipping the switch up.
4. Press the Start Heat button.
5. The HEAT ON indicator light will illuminate and stay
on as long as the element is heating the screed
plates (approximately 20 minutes).
NOTE: The engine speed automatically decreases to
idle after the heat cycle completes.
6. If the heat cycle has completed but the screed
plates still require heating, restart the cycle by
repeating Step 4.
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.
NOTE: You can set the screed directly onto a fresh
mat of hot asphalt while running the heating
system, allowing the heat of the asphalt to
help heat the screed plate.
Set the Screed and Endgates
1. Move paver to the starting position for paving.
2. Extend the screed to the desired width.
3. To set the depth, you can place a small starter block
under the screed while you make adjustments.
