After Completion Of Work; After Cold Weather - Komatsu D61EX-12 Operation And Maintenance Manual

OPERATION

AFTER COMPLETION OF WORK

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.
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. To prevent the battery
electrolyte from freezing in the night, do not add water after the day's work.

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 "USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERA-
TURE (PAGE 4-10)".
If for any reason permanent antifreeze cannot be used, and an ethyl glycol base antifreeze (winter, one sea-
son 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.
