6 – DIESEL ENGINE COLLING SYSTEM
The cooler is located in the rear side of the machine, under the engine cover.
A special indicator on the dashboard signals inefficiency of the diesel engine cooling
circuit.
The level is checked and topped up with the engine cold; should the refilling cap
“E” still be hot, use a protection glove or a cloth soaked in cold water.
Cooling liquid quantity: 3 l
The cooling liquid refilling has to be done only in case of pipe failure (leakage).
7 – TRACK TENSIONING DEVICE
This device is used to restore correct track tightness if they loosen during use.
8 – CHECKING TIGHTNESS OF NUTS AND BOLTS
Periodically check tightness of the main parts of the machine:
- Crawler wheel (nuts and bolts class 12.9);
- Guide rollers;
- Engine retaining supports;
- Engine vibration-damping;
- Full dash board unit.
The resistance class of the nuts and bolts not specifically indicated is 8.8
To facilitate the fastening operations, the table on the side lists the driving torques
according to the relevant dimension and class of resistance (values expressed in
daNm = Kgm).
