There is a spray down system on both sides of the
Leeboy 8608 paver. A spray wand is conveniently
located by the engine access panel on each side of the
paver. (Figure 4-53) The hose reels are located inside
the access panel.

Figure 4-53. Spray Down Wand
To operate the spray down system:
1. Open both hopper wings completely and raise the
screed. (Page 4-29)
2. Turn the citrus tank valve clockwise. (Figure 4-52)
3. Push the Spray Down button on the main control
panel to turn system ON.
4. Extend hose from the reel.
5. Squeeze the wand handle to spray desired areas.
6. Turn the citrus tank valve counterclockwise and
press the Spray Down switch on the control panel to
turn system off when nished.
Start at the front of the machine and work rearward, using a
scraper if needed, paying particular attention to:
• 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.
Heating the Screed and End Heating the Screed and End
GatesGates
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.
The paver is equipped with the Legend 815HD (heavy
duty) electric heat system to heat the screed and
extensions. A belt-driven generator provides power to
the electric heat control box mounted above the screed.
It is also pre-wired for the heated end gates option.
(Page 4-43) (If not equipped with this option, the left
and right endgate switches do not function.)
S-curve heating elements in the main screed with
straight heating elements in the extensions cycle during
heat-up saves horsepower and fuel consumption while
paving.
Once the heating system has been enabled, the electric
heat 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: Operating in cold temperatures may affect the
screed plate temperature slightly.
NOTE: Allow the screed (and screed extension) to
heat 15 minutes before beginning to pave.
Lower the screed two inches off the ground
while heating to prevent cold air and wind
from affecting the heating process.
