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
given, so that chemical substances used for this purpose do not damage the materials of the
hydraulic system.
Hydraulic lines should be replaced after 4 years of rotary rake use.
Detailed tightness and technical condition inspection of hydraulic system should be
made at least annually.
The oil used in the hydraulic system 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
