4-4 LeeBoy 8515E Conveyor Paver
Operation
DPF Regeneration (REGEN)
When starting the engine, a sequence of screens will
display on the PV480 digital display unit on the operator
console. (Page 4-5) First you will see “booting” notated
in the upper left corner, followed by a logo display, then
the gauge screen is displayed. The lit status icons at the
top of the screen will disappear momentarily.
DPF regeneration is the term given to the cleaning
process where the exhaust temperature is raised in
an attempt to safely burn off any soot and undesired
combustion gas captured in the Diesel Particulate
Filter (DPF) in the exhaust system. When the DPF lter
reaches a soot saturation level between 25 - 45 per-
cent, the onboard engine ECU (Engine Control Unit) will
activate a regeneration cycle.
To reduce the amount of particulate
matter and maximize efciency, use API-CJ4 (or
ACEA-E9 European equivalent) engine oil. Running
the engine at 1800 RPMs will also provide more
efcient operation and allow automatic regeneration
while paving.
During normal operation, the DPF is cleaned automati-
cally. Under certain conditions, the operator may have
to instruct the control system to perform the cleaning
process.
The DPF icon indicates the level of soot build-up on a
scale of Level 0 - 5 and changes color. Regeneration
will occur automatically at Level 1 - 2.
It is important to perform a parked, manual regenera-
tion BEFORE the engine reaches as high as Level
4. If the DPF reaches Level 4 - 5, non-warranty factory
assistance from the engine manufacturer is required.
The engine speed will increase during regeneration
and there may be a noticeable sound difference. Once
regeneration is complete, the engine will return to
normal idle speed.
Once the DPF cycle has been activated, it is important
not to shut off the engine as the regeneration cycle
will fail and could possibly damage the engine. If the
regeneration cycle fails, the ECU may attempt a second
regeneration depending upon how blocked the lter has
become. If the system does not allow a second regen-
eration, this means the lter is blocked more than 80
percent and needs to be cleaned or replaced.
DO NOT idle machine any longer than
necessary as too much idling can cause soot to build
up in the DPF, requiring more frequent regeneration.
Start-Up Procedure
DO NOT leave the operator station
unattended while the paver is in gear or in motion.
Operator must return joysticks to the neutral position
and turn the RUN/STOP switch to the STOP position
before leaving the operator platform.
Verify there are no people, obstacles
or other equipment in the machine’s path before
starting the engine.
1. Clear auger and conveyors before starting engine.
2. Position joysticks to NEUTRAL (center).
3. Insert key into the ignition and turn clockwise to the
RUN position. The “Wait to Start” light on the control
panel will illuminate.
4. Wait for the “Wait to Start” light to turn off, then turn
key to the START position to start.
DO NOT hold the starter longer than
10 - 15 seconds. If the engine does not start, allow
the starter to cool two or three minutes.
Using starting additives, such as
ether, is not recommended as severe engine damage
can occur.
5. Allow engine to warm up a few minutes before
moving paver for more efcient operation. In cold
weather let hydraulic oil warm to 60° before moving.
6. Set engine RPM using the throttle up and down
buttons on the Engine Screen on the digital display
screen.
Stopping the EngineStopping the Engine
1. Move joysticks to the NEUTRAL position.
2. Reduce engine to 1300 RPMs.
3. Turn ignition key on instrument panel counterclock-
wise to the OFF position and remove key.
NOTE: If for any reason the engine does not shut
down when key is turned off, push in the E-Stop
button.
