COLD WEATHER OPERATION

AFTER DAILY WORK COMPLETION

Performing idle-running of the tracks is dangerous, so 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, always observe the following precautions.
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.
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 and the machine can start 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.
1. Swing 90° with engine at low idling and bring the work
equipment to the side of the track.
2. Jack up the machine until the track is raised slightly from the
ground. Rotate the track under no load. Repeat this proce-
dure on both the left and right sides.

AFTER COLD WEATHER SEASON

When season changes and the weather becomes warmer, do as follows.
Replace the fuel and oil for all parts with oil of the viscosity specified.
For details, see "LUBRICANTS, FUEL AND COOLANT SPECIFICATIONS ( 4-8 )".
If for any reason permanent antifreeze cannot be used, and an ethyl 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 soft water.
