Operation
Heating the ScreedHeating the Screed
Heating the screed helps prevent hot mix from sticking
to the cold screed plate and produces a smooth, tight
mat surface. This should be performed before paving
and if the paver is idle long enough for the screed to
cool between loads.
Allow the screed (and screed extension) to heat 15
minutes before beginning to pave.
NOTE: Lower the screed two inches off the ground
while heating to prevent cold air and wind
from affecting the heating process.
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.
The LeeBoy 8515E Conveyor Paver is equipped with an
electric heat system that heats the screed and screed
extensions. 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.

OFF.
Never spray cleaning solvent or
release agent near the screed heating element or
near open ame. These agents are highly ammable
and can ignite, causing serious personal injury.
Start at the front of the machine and work rearward,
using a scraper if necessary, paying particular attention
to ensuring built-up material is removed from:
• Push Rollers: Rotate the rollers while cleaning and
soak bearing ends to maintain free rotation.
• Hopper and Conveyors: Thoroughly clean surfaces
and any material accumulating in chains, drive
sprockets, idler shaft, bearings and tunnel areas.
AFTER cleaning the machine, operate the conveyors
briey to carry solvent into return areas where it can
help dissolve hidden asphalt material.
• Augers: Scrape away any accumulated material
around bearings and clean contact surfaces down to
the metal to avoid quick build-up while paving.
• Screed: Face and bottom plates should be clean and
smooth on the main and screed extensions to achieve
a smooth paving mat.
• Operator Platforms: Be sure to wash away solvent
residue so walk boards and operator platforms do not
remain slippery.
