AFTER COMPLETION OF WORK
2
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 impossible, park
the machine on wooden boards. The boards help protect the tracks
from freezing into the soil and the machine can start next morning.
•
Open the drain valve and drain any water collected in the fuel sys-
tem 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 morning
before beginning work. To prevent fluid in the battery from freez-
ing in the night, do not add the water after the day's work.
AFTER COLD WEATHER
2
When season changes and the weather becomes warmer, do as follows:
•
Replace the fuel and oil for all parts with oil of the viscosity speci-
fied. For details, see "USE OF FUEL, COOLANT AND LUBRI-
CANTS" on page 3-7.
•
If for any reason permanent antifreeze cannot be used, and an ethyl-
ene 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 system thoroughly, and fill with
fresh coolant.
