Filling the oil tank with hydraulic oil
The oil used for filling must be clean. Do not mix different oils.
Hydraulic oils must have been dealt with according to cleanliness requirements ISO 4406: -/16/13.
Hydraulic oil that is approved for Hiab products must comply with one of the following standards or
equivalents:
- ISO 11158 HV
- DIN 51524 part 3 HVLP
- ISO 6743/4 L-HV
Suppliers of hydraulic oil must verify that the quality and performance of the oil complies with the
above standards.
When changing from mineral oil to a non-polluting synthetic oil, or when changing to biodegradable
oil, contact a Hiab service workshop.
Viscosity of oil
The viscosity of the oil is of great importance to achieve high efficiency of the hydraulic system.
The naming of the oil in the table below: 32, 46 or 68 tells the viscosity of that oil at 40°C (reference
temperature).
Viscosity of oil at 40°C
The recommended viscosity during normal working conditions is between 16 and 40cSt.
Hiab strongly recommend an oil working temperature below 70°C. If necessary consider an oil
cooler or heater.
NOTE
When working in arctic condition consider an oil with lower viscosity than the 32 oil
in the table above.
Environmentally Friendly Oil
The environmentally friendly oils recommended for Hiab products are ester based synthetic
hydraulic fluids (synthetic ester).
NOTE
Vegetable oils do not meet Hiab's requirements and must not be used.
After filling the tank
1. Operate each crane function to its end positions.
