Always spray down the machine before and after paving.
Spray clean with solvent or release agent on any part
of the paver that comes into contact with asphalt to
prevent buildup that will damage the machine over time.
The green citrus tank ller cap is located on the screed.

There is a spray down system on both sides of the
Leeboy 8520C paver for your convenience. The wand
is conveniently located on each side of the operator’s
station. (Figure 4-54) The hose reel is located inside
the access panel on each side.
• Ensure the area is clear of others before spraying.
• Open the hopper wings and raise the screed.
• Allow the screed to cool at least 10 minutes before
spraying to prevent possible burns from solvent spray
on a hot screed. The screed should be warm, but not
hot.

Ensure the area is clear of others and
ammable materials before spraying to prevent
serious injury. Allow the screed to cool at least 10
minutes before spraying. Screed should be warm,
but not hot.
To operate the spray down system:
1. Turn the Spray Down switch on the control panel
ON. (Figure 4-55)

OFF when nished.
When using solvents and release
agents, DO NOT allow cleaning solvent to run onto
the ground. Only spray down the machine in a desig-
nated 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
briey 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
become slippery.
