6.2 – Motor Maintenance
In order to keep the motor in perfect efficiency condition, it is necessary to observe a minimum maintenance
activity as described in the chapters here below.
6.2.1 – Filters Cleaning Process
The system filters must be changed after the first 200 working hours.
The subsequent filters’ replacement or cleaning has to be performed every 3 months or 500 operating hours,
whatever one is the first to occur (in case a filter cleanliness level indicator is present, as soon as the signal
of locking is received).
6.2.2 – Operating Fluid Change
The periodic scheduling of oil replacement is based on the working condition of the motor, of the
environmental conditions and of the quantity of oil in the system.
As indicated in the “Hydraulic System Maintenance”, it is recommended to perform a periodic analysis of the
operating oil in order to determine its characteristics (viscosity, oxidation, filtration level, etc.).
For other operating fluids, it is compulsory to follow the relevant manufacturer’s instructions.
6.2.3 - Viscosity
Verify that the viscosity level is within the recommended values as indicated in the “Operating Fluids”
section.
6.2.4 - Oxidation
Mineral oil gets oxidized proportionally to the usage degree and operating temperature. The oil oxidation
gets evident because of its change of colour, bad smell, acidity increase and because of the generation of
sludge inside the tank.
In case symptoms of this kind are detected, the system oil must be immediately changed.
6.2.5 – Water Presence
The presence of water inside the oil can be determined by taking oil samples from the bed of the tank: oil
floats on water, so, if present, water tends to stay on the tank’s bed.
If its presence is determined, water must be regularly purged.
Presence of water in the hydraulic system can severely damage the motor.
