Usage:
If the diesel engine is in good mechanical condition, and the precautions necessary for cold weather operation are taken, ordinary cold weather will not cause difficulty in starting or loss of efficiency.
If the engine fails to start and smoke is coming from the exhaust turn switch to heat position for a longer period. If no smoke is coming from the exhaust, prime the fuel system. See the topic, PRIMING THE FUEL SYSTEM.
LUBRICANTS: When it becomes necessary to start the engine in temperatures below 32°F (0°C), lubricants of lower viscosity should be used. See the topic, LUBRICATION SPECIFICATIONS.
COOLANT: When the temperature is below freezing, use sufficient antifreeze solution in the cooling system to prevent freezing. See the topic, COOLANT SPECIFICATIONS.
ELECTRICAL EQUIPMENT: During cold weather, give more attention to the condition of the battery. Test it frequently to assure sufficient power for starting. All switches and connections in the electrical system should be inspected and kept in good condition to prevent losses through improper contacts. See the topic, BATTERY.
FUEL: Fuel must be "free flowing" enough to flow readily through the fuel lines at the lowest temperature at which the engine will be started and operated. For additional information, see the topic, FUEL SPECIFICATIONS.
