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.
In the event of necessity of changing 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

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.
