4.9 Starting in Cold Weather
Background
In temperatures below freezing, diesel fuel will coagulate and cause problems with
starting the machine. The engine will require preheating. Preheating can be
achieved using the installed 120V block heater or by using a heater or other heat
source indoors.
Guidelines
In temperatures between 32°F (0°C) and -20°F (-29°C) the machine should be
preheated using the block heater. Plug the block heater into a 120V outlet. Let
the engine warm for 2.5 hours minimum.
In temperatures below -20°F (-29°C), the machine should be preheated indoors.
The block heater should also be used during preheating procedures.
After preheating, the machine can be started normally. See topic Starting the
Machine.
4.10 Recommended Fuel
Low temperatures cause diesel fuel to gel. Always use the proper fuel for the
conditions. Follow the guidelines in the table below.
1
Your engine may require ultra low sulfur fuel. Consult the engine owner’s manual.
NOTICE: Consult the engine owner’s manual regarding the use of biodiesel fuel in
this machine. Some biodiesel blends may clog the fuel system or gel at cold
ambient temperatures sooner than petroleum-based diesel.
