Bulldozer track.

The bulldozer moves along a snow-covered surface.

Cranes install a whip of large-diameter pipes in a trench.

Preparing machines for pipe-laying work.

Before daily servicing of the machine, the gear shift lever is set to neutral.

The brake lock and safety lever are locked.

The bulldozer blade and ripper are lowered to the ground or onto supports.

The pipe-layer boom is lowered to the ground.

The counterweight is moved back.

The bulldozer operator inspects the machine.

The machine is washed and cleaned of dirt.

After the external inspection, the tightness of the connections of all pipelines and high-pressure hoses, the condition of all containers and fasteners are checked.

The fastening of the air cleaner, turbocharger, muffler, road wheel covers and support rollers is checked.
