LeeBoy 8510E - Heating the Screed

LeeBoy 8510E Conveyor Paver 4-21
Operation
Heating 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.
Overheating the screed can warp the
screed plate and possibly cause damage. If screed
extensions lock, allow the machine to cool before
attempting to extend or retract. Replace a warped
screed plate immediately.
The LeeBoy Model 8510E Conveyor Paver is equipped
with two propane burners on the main screed and one
burner on each screed extension. An electric heat
option is also available. (Page 4-23)
To operate the Spray Down system:
1. Turn the Spray Down switch on the control panel
ON. (Page 3-6)
2. Extend hose from the reel.
3. Squeeze the wand handle and spray area. Release
the wand handle when nished.
4. Turns the Spray Down switch on the control panel
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.
When using solvents and release
agents, consider the environment and DO NOT allow
cleaning solvent to run onto the ground. Only spray
down the machine in a designated area away from
the paving site.
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.
