AFTER COMPLETION OF WORK 3
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.
q Remove all the mud and water from the machine body. In particular, wipe the hydraulic cylinder rod clean to
prevent damage to the seal caused by mud or dirt on the rod surface getting inside the seal together with
drops of water.
q 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 so the machine can move next morning.
q Open the drain valve and drain any water collected in the fuel system to prevent it from freezing.
q Fill the fuel tank to the full in order to prevent moisture from forming dew in the tank room, as the ambient tem-
perature goes down.
AFTER COLD WEATHER 3
When season changes and the weather becomes warmer, do as follows.
q 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 (4-11)“.
q If for any reason permanent antifreeze cannot be used, and an ethylene 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 coolant.
