materials such as, for example, very high concentrations of dust,
humidity, substances with high salt contents.
4.2.5 Use Grease with a high pour point (
180°C) featuring elevated
resistance to mechanical stress. Do not use grease containing acid,
naphtha, or solid particulate.
4.3 Checking the Hydraulic Oil
4.3.1 Once a week check the hydraulic system for possible external or
internal leakage of oil in the Power Take-Off
– pump assemblies.
4.3.2 Each month (or after 200 working hours) check for possible leakage of
oil from the unions of the hydraulic system, which may have worked
loose due to vibration generated when the vehicle is travelling. If
necessary, tighten ringnuts, hose clamps, and screws.
4.3.3 With the same frequency check for leakage from between the
extensions of the lift cylinder due to wear of the relative seals. If you
notice signs of leakage take the vehicle to an authorised service
centre.
4.3.4 Check also that the oil tank filler plug vent line is not obstructed and
that the oil level in the tank is correct (see point 1.2.4. under the
heading Oil tank).
4.3.5 If necessary, top up the oil or change the oil if the characteristics of
the original oil contents have altered due to ageing. Use Hydraulic Oil
viscosity class 32/46 (ISO 3448) and viscosity index 106/110 (ASTM
D2270).

DO NOT DISPERSE SPENT OIL IN THE
