2.27.2 Cold Weather Operations.
Use the following steps to start the paving
machine at temperatures below 50°F (10°C).
Turn the ignition switch to the preheat
position and hold for 10 seconds to heat
the induction heater.
operated longer than 30 seconds. If
engine does not start, allow starter
motor to cool for two to three
minutes before trying again. If engine
fails to start after three attempts,
notify Unit Maintenance.
Turn the ignition switch to the start position
and immediately release when the engine
starts. The switch will spring return to the
b. Maximum extreme cold temperature for machine
operation is -50°F (-46°C).
Paving machine operation will be
c. If the machine will start at temperatures higher
than -50°F (-460C), the machine can be
operated after the engine coolant temperature
starts to rise at the gauge panel temperature
gauge. Other non-propulsion hydraulic functions
temperature reaches 100°F (38°C). No other
special operating procedures are required.
2-98 2.27.3 Extreme Dusty and Sandstorm Conditions.
a. Under extreme wind driven dust conditions,
check air cleaner service indicator every 1/2
hour of operation.
b. Service the air cleaner per table 2-1, Operator
PMCS, twice daily.
c. Replace air cleaner filter element per paragraph
3.3.7 after every 50 hours of continuous
operation in extreme dusty conditions.
Death or serious injury could occur if
compressed air is directed against
skin. Do not use compressed air for
pressure is/was reduced to 30 psi
(207 kPa) or less. When working with
compressed air, always use chip
guards, eye protection, and other
personal protective equipment.
d. Use compressed air to blow out all dirt and
debris from hydraulic oil cooler and radiator.
e. The paving machine shall not be operated in a
sandstorm. Take the following precautions to
protect the machine from damage during a
Ensure extension screeds are retracted,
hopper wings are open, and screed is in
travel position to protect cylinder shafts
from abrasive blowing sand.
Coat chrome guide shafts on screed with
a heavy coat of automotive and artillery
grease (Item 5, Appendix D).
Cover air cleaner cap assembly with
Install protective covers on operator
console and screed crew control boxes.
Close all access doors and covers.
2.27.4 High Altitude Operation. The paving machine
diesel engine has a considerable amount of reserve
horsepower to compensate for machine operation at
altitudes up to 10,000 ft (3050 m). If engine bogs down
at high altitude, reduce paving speed until engine runs
