10.1.1 Oil change procedure
The lubricant must be replaced in all of the following cases:
One of the oil replacement intervals has been reached, in this case see the “Checks and Maintenance Table” and the
“OIL REPLACEMENT INTERVAL”;
Significant oil leakage;
Suspected external contamination of the lubricant.
Bring the gear reducer to a surface temperature below 30 °C before changing the oil: with moderately warm oil, the
emptying procedure and the removal of deposits is easier. Take all necessary precautions to avoid burns due to high
temperature of the gear reducer and/or oil.
CAUTION – HOT PARTS
Indicates a serious thermal hazard which may endanger personal health and safety.
Put in place a system to collect the lubricant that is proportional to the gear reducer on which maintenance is to be
carried out;
Identify the filler and drain plugs of the gear reducer (the filler plug may be the drain plug); First unscrew the filler
plug and then the drain plug, paying attention to gradually reducing any internal overpressure;
Bleed out all the oil and collect it with the system put in place;
Wash the inside of the gear reducer’s casing with the same type of oil required for operation and empty it again;
Replace the gasket of the drain plug and tighten it again by applying the appropriate tightening torque (see the table
with the “TIGHTENING TORQUE FOR OIL PLUGS”);
Pour the new lubricant into the gear reducer until you reach the required level, which corresponds to the centre line of
the indicator plug or to the upper notch of the dipstick; see the LUBRICATION paragraph for overflow levels. Refer to
the tables in the LUBRICATION paragraph for the type of oil and the recommended viscosity.
Replace the gasket of the filler plug and tighten it again by applying the adequate tightening torque (see the table
with the “TIGHTENING TORQUE FOR OIL PLUGS”);
After about 30 minutes verify whether the level is correct (top up as required) and check for any oil leaks. Clean the
gear reducer’s surface with antistatic materials. As in the case of first commissioning, there may be air pockets
trapped between the gears and the casing, which would prevent the filling process from being completed. After the
first minutes of operation, stop the gear reducer, check the oil level and top up if necessary;
Dispose of used oil in accordance with current local regulations.
