permitted. In a new manure spreader, the hydraulic system is filled with L HL32 Lotos
hydraulic oil.
The manure spreader's hydraulic system should be completely tight sealed. Checking
tightness of the hydraulic system involves connecting the machine with the tractor and
activating the floor conveyor several times. In the event of confirmation of an oil leak on
hydraulic conduit connections, tighten connections, and if this does not remedy faults then
change conduit or connection elements. If oil leak occurs beyond connection, the leaking line
of the system should be changed. Change of sub-assemblies is equally required in each
instance of mechanical damage.

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.
Hydraulic conduits should be replaced after 4 years of manure spreader 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
occurrence of irritation consult a doctor. Hydraulic oil in normal conditions is not harmful to
