5.7.1 HYDRAULIC OIL
Always adhere to the principle that the oil in the trailer hydraulic system and in the tractor
hydraulic system are of the same type. In the event of application of different types of oil
make certain that both hydraulic substances may be mixed together. Application of different
oil types may cause damage to trailer or tractor. In a new machine, the hydraulic system is
filled with L HL32 Lotos hydraulic oil.

If it is necessary to change hydraulic oil for another oil, check the recommendations of the oil
Manufacturer very carefully. If it is recommended to flush the system with the appropriate
preparation, then comply with these recommendations. Attention should be given, so that
chemical substances used for this purpose do not damage the materials of the hydraulic
system. During normal trailer use change of hydraulic oil is not necessary, but if required, this
operation should be entrusted to a specialist service point.
Because of its composition, the oil is not classified as a dangerous substance, however long-
term action 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 apply organic solvents (petrol,
kerosene). Contaminated clothing should be changed to prevent access of oil to skin. In the
event of contact of oil with eye, rinse with large quantity of water and in the event of the
occurrence of irritation consult a doctor. Hydraulic oil in normal conditions is not harmful to
the respiratory tract. A hazard only occurs when oil is strongly atomised (oil vapour), or in the
case of fire during which toxic compounds may be released. Oil fires should be quenched
