• When the ambient temperature is low, the capacity of the battery considerably drops. Cover it, or remove it
from the machine to place it in the warm place. Restore it again before the operation.
• If the electrolyte level is low, add distilled water in the morning before beginning the work. Do not add water
after the day's work to prevent diluted electrolyte in the battery from freezing during the night.
PRECAUTIONS AFTER DAILY WORK COMPLETION IN COLD WEATHER

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.
• In cold weather condition, add DEF to the defined level strictly. If adding more than the defined level, it may
expand to break the devices in the tank when it freezes.
If DEF tank level is lower than the defined level for the cold weather, DEF may freeze easily to damage the
parts in DEF system. If the filler cap freezes, defreeze and open.
• After operation in water or mud, remove water from undercarriage as described below to extend undercar-
riage service life.
Swing 90 ° with engine at low idle and bring the work equip-
ment to the side of the track.
Slowly push up the machine until the track is raised slightly
from the ground. Perform idle rotation of track. Perform this
procedure on the right and left sides alternately.
AFTER COLD WEATHER SEASON
When the season changes and the weather becomes warmer, do as follows.
