5.10. CONTROLLO AL CIRCUITO OLEODINAMICO
These are the recommended checks for the hydraulic circuit:
 oil in the tank: through the level visually
 diesel engine pumps effi ciency: when the engine is running, commute the command
key to “stabilizers”, activate a stabilizer until it is completely retired and check that
the pressure is within the maximum value shown in chapter 1. When the stabilizers
are under pressure, start the generator and check the voltage is 220V + 10%.
 electric engine pump effi ciency. When the engine is running, turn the key onto
“stabilizers” and move a stabilizer until it’s completely retired; then check the
pressure value is within the maximum shown in chapter 1.
 fi lters effi ciency. Open the engine hood and after a few minutes (10 minutes during
the cold season) check the indicators are not on the red.
 maximum pressure valves. Using the thermal engine and moving the arms until
they’re completely retired, the manometer should show the maximum value as shown
in chap 1.
 fl exible pipes: check if they’re not damaged or blistered near the hose fi tting, damages
in the metallic/textile stranded wire or permanent foldings. The black surface fi lm
sealing is not dangerous for the pipe
 cylinders locking valves. Put the stabilizer cylinders under pressure, after lifting the
lifting cylinder, jib open (and then closed): mark the stems with a tape and measure
the distance from a point (as the fl ange thread) to the plaster. The subsidence allowed
is none within 15 minutes, 1mm after an hour.
 Oil leaks: Maximum allowed is few on the stems and on the spiral pipes.
