Starting the Machine in Extremely Cold Weather
Background
In temperatures below 32°F (0°C), it may be necessary to preheat the fuel inside

element specially designed for this purpose.
HI 200 HD and HI 300 HD machines are also equipped with a thermostatically
controlled nozzle heater as described below.
