Komatsu — 14.3 AFTER COLD WEATHER

OPERATION 14.2 PRECAUTIONS AFTER COMPLETION OF WORK To prevent mud and water in and on the machine from freezing and making it impossible for the machine to move on the following morning, observe the following precautions. ! Mud and water in and on the machine should be completely removed. ! Park the machine on hard, dry ground. If this is not possible, park the machine on wooden boards. The boards will help protect the machine from freezing to the soil. ! Drain any water collected in the fuel system, to prevent it from freezing. !

The battery capacity will drop in low freezing temperatures, therefore 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 the season changes and weather is warmer, proceed as follows. ! Replace the fuel and oil, use oil of the viscosity specified. For details, see "20. USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE" on page 3-10. !

If for any reason permanent antifreeze cannot be used, and 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. 2-65
