14. COLD WEATHER OPERATION 14.2 AFTER COMPLETION OF WORK To prevent mud, water, or the undercarriage from freezing and making it impossible for the machine to move on the following morning, always observe the following precautions. Mud and water on the machine body should be completely removed. This is to prevent damage to the seal caused by mud or dirt getting inside the seal with frozen drops of water. Park the machine on concrete or hard ground. If this is impos- sible, park the machine on wooden boards. Open the drain valve and drain any water collected in the fuel system to prevent it from freezing.
When operating in mud or water, remove the water from the undercarriage to extend the life of the undercarriage. As the battery capacity drops markedly in low temperatures, cover the battery or remove it from the machine, keep it in a warm place, and install it again the next morning. 14.3 AFTER COLD WEATHER When season changes and the weather becomes warmer, do as follows. Replace the fuel and oil for all parts with oil of the viscosity specified. For details, see “20. USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE”.
If for any reason permanent antifreeze cannot be used, and an ethyl glycol base antifreeze (winter, one season type) is used instead, or if no antifreeze is used, drain the cooling system completely, then clean out the inside of the cooling system thoroughly, and fill with fresh water. When it is unnecessary to use the automatic starting aid (APS) (when the ambient temperature is above 15°C), always keep the fuel valve closed. 2-81
