PRECAUTIONS AFTER DAILY WORK COMPLETION IN COLD WEATHER
k k
WARNING
Performing idling of the tracks is dangerous, stay well away from the tracks.
To prevent mud, water, or the undercarriage from freezing and making it impossible for the machine to move on
the following morning, observe the following precautions.
• Remove all the mud and water from the machine body. In particular, wipe the hydraulic cylinder rods clean
to prevent damage to the seal caused by mud, dirt, or drops of water on the rod from getting inside the seal.
• Place the machine on a firm, dry ground.
If this is impossible, park the machine on boards.
The boards prevent the tracks from freezing to the ground, and allow the machine to move the next morn-
ing.
• Open the drain valve and drain any water collected in the fuel system to prevent it from freezing.
• Fill up the fuel tank. This minimizes moisture condensation in the tank when the temperature drops.
• After operation in water or mud, remove water from undercarriage according to the procedure to extend un-
dercarriage service life.
1.
Run the engine at low idle and swing the upper struc-
ture 90 ° to bring the work equipment to the side of the
