Maintenance 45
o Periodically high temperatures, pressure changes and oxygen in the air are hard
conditions for hydraulic oil. In such conditions, it is recommended to use high quality
hydraulic oil.
o Use only oils of the same quality and viscosity - do not mix different types of oils!
o If the vehicle is going to be operated in extremely high or low outside temperatures,
use special hydraulic oil. In this case, it is recommended to contact the manufacturer.
o If painted surface gets contaminated by oil, clean immediately.
Biodegradable hydraulic oils
When using biodegradable hydraulic oils, they must comply with the regulations of the
Mechanical Engineering Industry Association (VDMA) No. 24 568 and with EN 15380 and DIN
51 524-2. Oils that do not meet the requirements of VDMA are not recommended.
The water content of oil should be tested. If the water content is greater than 1%, an oil change should
be carried out. The high-water content causes the release of harmful chemicals.
Environmentally friendly disposal:
o While choosing hydraulic oil, liquid grease and grease, you should pay attention to their
impact on the environment and health hazards and familiarize yourself with the
regulations regarding proper disposal.
o Laws, regulations and manufacturers' guidelines must be observed.
o In the event of a hydraulic oil leak, immediately stop work, close the shut-off valve and
collect the spilled oil with a binding agent.
o The oil must not be allowed to soak into the ground!
8.5.2 Mixing hydraulic oils
Some hydraulic oils must not be mixed together, as this may result in malfunctions and even a
major malfunction. The exception is mineral hydraulic oil, because mineral oils with similar
parameters can be mixed together.
Use only the hydraulic oils listed under "Permitted hydraulic oils". Do not mix different types of hydraulic
oils.
A mix of oils or the use of oil with inferior parameters may lead to malfunctions during operation or a
serious failure.
