OPERATION COLD WEATHER OPERATION AFTER DAILY WORK COMPLETION 0. Performing idle-running of the tracks is dangerous, so stay well away from the tracks. After completion of operations, fill the fuel tank to prevent the formation of water caused by conden- sation of moisture in the empty space in the tank when the temperature goes down. 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 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. After operation in water or mud, remove water from undercarriage as described below to extend undercarriage service life. 1. Swing 90є with engine at low idling and bring the work equipment to the side of the track. 2. Jack up the machine until the track is raised slightly from the ground. Rotate the track under no load. Repeat this proce- dure on both the left and right sides.
AFTER COLD WEATHER SEASON 0. 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 "LUBRICANTS, FUEL AND COOLANT SPECIFICATIONS ( 4-8 )". 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 soft water. 3-93 WARNING
