5.7.1 HYDRAULIC OIL
It is absolutely necessary to observe that the oil in the trailer's hydraulic system and the
tractor's hydraulic system must be of the same type. If different types of oil are used, make
sure that both hydraulic means can be mixed together. The use of different types of oil may
cause damage to the trailer or agricultural tractor. The new machine is filled with L HL32
Lotos hydraulic oil.

If you need to change the hydraulic oil for another oil, read the oil manufacturer's instructions
carefully. If he recommends flushing the system with an appropriate preparation, follow these
recommendations. It must be ensured that the chemicals used for this purpose do not act
aggressively on the materials of the hydraulic system. During normal operation of the trailer,
it is not necessary to change the hydraulic oil, however, if necessary, this operation should be
entrusted to specialist service centres.
The oil used, due to its composition, is not classified as a dangerous substance, however
long-term effects on the skin or eyes may cause irritation. In the event of contact of oil with
skin, wash the place of contact with water and soap. Do not use organic solvents (gasoline,
kerosene). Soiled clothing should be removed to prevent oil from getting on your skin. If the
oil gets into your eyes, flush them with plenty of water and in case of irritation contact your
doctor. Hydraulic oil under normal conditions is not harmful to the respiratory tract. The
hazard only occurs when the oil is strongly atomized (oil mist), or in the event of a fire during
which toxic compounds may be released. Oil should be quenched with carbon dioxide, foam
or extinguishing steam. Do not use water to extinguish a fire.
