PRECAUTIONS TO BE TAKEN EVERY DAY AT THE END OF WORK 3
DANGER
Spinning the tracks is dangerous; when performing this operation pay the utmost attention that no one
comes close to the machine.
q
To prevent the mud and water present on the undercarriage from freezing, thus making it impossible to move
the machine the following morning, always take the following precautions.
q
Remove any mud and water that may be present on the machine body. In particular, clean the hydraulic
cylinder rod to avoid any damage to the gasket due to the penetration of the mud or dirt present on the rod
surface together with water drops.
q
Park the machine on firm and dry ground.

If this is not possible, position it on wooden boards to prevent the tracks from freezing on the ground, which
would make it extremely difficult to start the machine the following morning.
q
Open the drain valve and drain the water accumulated in the fuel system to prevent it from freezing.
q
Fill the fuel tank completely, in order to prevent the formation of condensate inside the tank when the
temperature decreases.
q
After working in water or mud, remove the water from the undercarriage by proceeding as indicated below, in
order to extend the life of the undercarriage.
1. Swing the turret 90° with the engine at low idling and bring
the work equipment to the track side.
2. Lift the machine using a jack until the track is slightly raised
from the ground. Make the track rotate idly. Repeat this
procedure on both the left and the right side of the
machine.
HOW TO PROCEED AT THE END OF THE COLD SEASON 3
At the end of the cold season, when the climate becomes warmer, proceed as follows.
q
Change fuel and oil with products having suitable viscosity. For further details, see "MAINTENANCE NOTES
