When you travel over a mound, always support the chassis with the dig end to prevent shock loads.

When the machine travels for long distances heat is generated in the undercarriage, which causes increased
wear. When possible, stop the machine and let it cool down.
If the track comes off the ground, the track will loosen. When you slew the machine, if the track is too loose the
track roller can ride up on the link. Always keep the correct track tension.
