Work connected with the repair, change or regeneration of system elements (conduits,
braking force regulator, control valve etc.) should be entrusted to specialist establishments,
having the appropriate technology and qualifications for this type of work.
5.6 HYDRAULIC SYSTEM OPERATION
Always adhere to the principle that the oil in the sand spreader hydraulic system and in the
tractor hydraulic system are of the same type. Application of different types of oil is not
permitted. In a new sand spreader, the hydraulic system is filled with HL32 hydraulic oil.
TAB. 5.5 HL32 HYDRAULIC OIL CHARACTERISTICS

The sand spreader's hydraulic system should be completely tight sealed. Checking tightness
of the hydraulic system involves connecting the machine with the tractor and engaging the
drive of conveyor belt and adapter discs. 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
conduit system should be changed. Change of sub assemblies is equally required in each
instance of mechanical damage. In the event of confirmation of damage of hydraulic motors
they must be replaced or repaired.
Contact of pneumatic leads with oils, greases, petrol etc. may cause damage and accelerate
ageing process. Bent conduits, permanently deformed, cut or worn should be replaced. In the
event of intensive use of the hydraulic system, the hydraulic conduits should be replaced
every 4 years regardless of their technical condition.
