COLD WEATHER OPERATION

AFTER COMPLETION OF WORK

Performing idle-running 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.
Park the machine on hard, 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 be moved the next morning.
Open the drain valve and drain any water collected in the fuel system to prevent it from freezing.
After operation in water or mud, remove water from undercarriage as described below to extend undercarriage
service life.
