Special precautions must be taken during cold weather. For service products to use in cold weather, see Chapter 5 of the MBE4000 Engine Operator's Manual .
Important: At outside temperatures below –4°F(–20°C), a coolant preheater is recommended.
- Periodically check the coolant mixing ratio (concentration of antifreeze in the coolant). Add more if necessary. The coolant mixing ratio should never rise above 60 percent antifreeze.
- Use low-viscosity lubricating oils for adequate lubrication.
- At temperatures below 32°F (0°C), do not use summer-grade (2-D) diesel fuel. To avoid fuel problems due to paraffin separation, use winter-grade (1-D or winterized 2-D) diesel fuel only.
- When winter-grade diesel fuel is not adequate, it is possible
to mix kerosene with the diesel fuel. Add the kerosene only when refilling
the tank, and before adding the diesel fuel.
Note: Engine power may drop according to the proportion of kerosene. For this reason, never add more than 50 percent kerosene to the fuel.
Warning: The addition of kerosene lowers the flash point of diesel fuel. To prevent fire and risk of injuries due to burning, do not smoke or use open flames around fuel mixed with kerosene. Comply with all appropriate safety regulations.
