Refer to the Manual delivered by the Manufacturer.
CAUTIONThe use of the gearbox with a low quantity of oil may damage the gears.
An excessive quantity of oil may cause seals and vents to leak and can remarkably increase the operation temperature.
WARNINGUnder normal operation conditions, the gear change can be carried out with the engine at low speed.
However, in case of emergency, gear shifting can be carried out with the engine at high speed, thus remarkably reducing clutch life though.
Oil level check
Check the oil level only when the engine is at a standstill. The proper oil level is between the upper and the lower notch of the dipstick.
After the first oil filling, a repair or the cleaning of the oil filter, the gearbox must be run for about two minutes.
Next the oil level check has to be carried out again two minutes after the engine has stopped.
CAUTIONBefore starting checking the oil level, check that the gearbox oil temperature complies with the normal operating specifications.
ENVIRONMENTRecover waste oil following the norms in force, relevant to special waste disposal.
DANGERService the gear box only if engine and propellers are stopped and the magneto-thermal is OFF. Before starting the inverter, carry out the filling and the consequent check of the oil level. The use of the gearbox with a low quantity of oil may damage the gears. An excess of oil might cause leaks to the seals and to the vent and increase remarkably the operating temperature.
