As the battery capacity drastically drops in low temperatures, cover or remove the battery from the ma-
chine, store the battery in a warm place, and install it again the next morning.
If the electrolyte level is low, add distilled water in the morning before beginning 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

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
track.
2.
Set the machine in the posture shown in the figure.
1)
Operate the work equipment control levers, and
lower the bucket bottom to the ground.
2)
Operate the work equipment control levers slowly,
and push the ground with the bucket bottom to
raise the track slightly.
3.
Operate the travel lever and perform idle rotation of
the track.
4.
Repeat performing steps 1 to 3 for both of the right and left.
