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.
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. If electrolyte level is found low, add distilled water in the morn- ing before beginning work. Do not add the water after day’s work so as to prevent fluid in the battery from freezing in the night. 14.3 AFTER COLD WEATHER When season changes and the weather becomes warmer, do as follows. l 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”.
l 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. 2-47
