. OPERATION COLD WEATHER OPERATION BATTERY WARNING When adding distilled water in cold weather, add it before starting operations in the morning to prevent the electrolyte from freezing. INSTALLATION OF RADIATOR CURTAIN (If equipped) If the display for the engine water temperature gauge does not enter the white range, install a radiator curtain. It is possible to adjust the degree of openingof the radiator curtain (fully closed, one side open, and both sides open). Adjust to a suitable condition to match the ambient temperature so that the engine water temperature gauge display enters the white range.
PRECAUTIONS 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, 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 water in mud or dirt getting inside the seal and freezing. Park the machine on hard, dry ground. If this is impossible, park the machine on wooden boards. The boards help protect the tracks from being frozen in soil and the machine can start next morning. 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 the electrolyte level is low, add distilled water in the morning before beginning work. Do not add water after the day's work to prevent diluted electrolyte in the battery from freezing during the night. 3 - 123 The battery generates flamma ble gas.

Do not let it flow in to drainag e ditches o r spray it on to the ground surface. When the ambient temperatu re drops, the ca pacity of the batter y will als o drop. If the battery charge ratio is low, the battery electrolyte ma y freez e.
