3.5.3 PRECAUTIONS TO BE TAKEN EVERY DAY AT THE END OF WORK
WARNING
q
Making the tracks turn idly is dangerous, therefore it is advisable to keep away from the tracks when car-
rying out this operation.
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 to-
gether 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
After working in water or mud, remove the water from the undercarriage by proceeding as indicated below, in or-
der to extend the life of the undercarriage.
1. Swing the revolving frame 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.
