CR 820 T
Pressure Cleaning
The entire paver can be pressure-washed to re-
move dirt and grease. When pressure washing the
paver:
Do not use a steam cleaner. Steam cleaning can
damage seals, bearings, gearboxes, and electrical
components.
Do not use an acid-based solvent with the pressure
washer. Use only mild detergents or degreasers.
Do not spray directly at electrical components,
seals, bearings, gearboxes, or hydraulic cylinder
rods. Water can be forced into electrical connec-
tions or the hydraulic system which could damage
the system.
Do not spray the screed or engine until it is cool.
Spraying a hot screed bottom with cold water could
warp the screed bottom. Spraying cold water on a
hot engine manifold could crack the manifold.
Use extreme caution when spraying in the engine
compartment. The engine compartment is full of
electrical and hydraulic components which could
be damaged by high pressure water. Use a com-
mercial engine cleaning foam to remove dirt and
grease from the engine compartment.
If spraying near electrical or hydraulic components
is required, cover the components before spraying.
Inducements
The ECM is constantly monitoring the Aftertreatment system to verify that the engine exhaust stream meets
the Tier 4 Final emissions requirements. If a problem exists with one or more components in the Aftertreat-
ment monitoring system and is not resolved within the allotted time, the engine torque will first be de-rated,
and eventually the engine will be locked to idle. This process is collectively called the Inducement Strat-
egy, and the ECM uses the DEF, WARN, and STOP icon illumination (along with messages transmitted on
the main J1939 Bus) to alert the operator.
INDUCEMENT DERATE TYPE REDUCED VALUE FROM AD-
VERTISED (RATED CURVE)
PRIMARY TORQUE 25%
SECONDARY TORQUE 50%
FINAL IDLE LOCK/ENGINE SHUTDOWN
WITH RESTART LIMITATIONS
