GELLING
Diesel fuel turns into a gel-like consistency at
temperatures around 0°F (-18°C): The diesel
forms wax crystals when the temperatures
drop below 15°F (-9°C). Then, as it gets
colder, these wax crystals turn to gel. This
thicker substance cannot pass the fuel filter,
so the engine may run intermittently, or may
not start at all.
At an extremely cold temperature, the
viscosity of hydraulic fluid and lubrication oil
may increase, and the torque of starter may
exceed its permissible value, hindering
proper starting. Additional care should be
taken under consideration when operating
the package in extreme cold weather
environments or ambient temperatures.
COLD WEATHER SAFEGUARDS
• Park the vehicle or equipment indoors
when not in use.
• Use a block heater or glow plugs.
• After initial start-up, run engine at idle
speed for several minutes prior to use.
• Maintain the vehicle's battery; this will
make it easier to start a diesel engine
in cold weather.
• In below zero temperatures a fuel line
de-icer product may need to be used.
• Check the fuel filter regularly to insure
that it contains no water.
• Vanguard™ Premium Synthetic Oil is
suitable for use from -40°F to 110°F (-40°C
to 43°C).
• Drain the moisture from the tank when
it is warm from extended operation.
• For additional engine precautions,
consult the Engine Operator’s
Manual.
4.10.2 HIGH TEMPERATURE OPERATION
High compartment temperatures can be
caused by high ambient temperatures, small
engine room, soundproof cases and other
reasons. Among these the most important
factor is the temperature of the intake and
cooling air. Reduce load duty cycle to less
than 60% when operating in ambient
temperatures above 104°F (40°C).
Extra care should be taken to keep the
engine and air compressor clean and to not
restrict the air flow around the unit. Consult
the Engine Operator’s Manual for fuel,
lubrication oil and cooling requirements
under extreme temperatures.
When operating the machine in high
temperature areas, precautions should be
taken to prevent overheating. At the
minimum, all coolers, including air passage
ways around the coolers, should be free of
debris and dirt. The fan, driven by its own
hydraulic motor, is designed to run
continuously to assure a constant flow of
cooling air.
The operator should be aware that high
temperatures
can
influence
engine
performance, which can directly effect some
machine function capacity outputs.
NOTE
As indicated in the
Section 4.2.1
(start-
up), a full interval lapse of ten (10)
seconds allows the glow plugs to assist
with key ignition start up in cold ambient
temperatures.
NOTE
DO NOT use compressor for short
periods of time. Compressor must run at
operating temperature or moisture will
build up in tank.
NOTE
Vanair
®
offers a cold weather kit option,
installed at the factory, which enables
operation at temperatures from 0°F down
to -40°F (-18°C to -40°C). Consult Vanair
for details.
