14.2 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, 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 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 the 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.
14.3 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 “20. USE OF FUEL, COOLANT AND LUBRICANTS
ACCORDING TO AMBIENT TEMPERATURE”.
‡ 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 water.
