5.23
Reduction of pressure is achieved by tilting the drain valve mandrel.
Remove the pneumatic line by loosening the nut (2).
Fit the new line.
The interior of the line should be clean.
The ends of the pneumatic line (1) must be cut exactly at right angles.
Clamping ring (3) should be fitted according to figure (5.10).
Reinforcing sleeve (4) of the line must be thoroughly depressed.
Check tightness of connections in accordance with Chapter (5.3.2).
5.4 HYDRAULIC SYSTEM OPERATION
Always adhere to the principle that the oil in the manure 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 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 hydraulic brakes several times by pressing the brake pedal in the tractor operator
cab and actuating the hydraulic cylinders of the spreader unit's slide gate and tailgate. Hold
the hydraulic cylinders in position of maximum extension for 30 seconds. In the event of
confirmation of an oil leak on hydraulic line connections, tighten connections, and if this does
not remedy faults then change line or connection elements. If oil leak occurs beyond
connection, the leaking line system should be changed. Change of sub-assemblies is equally
required in each instance of mechanical damage. In the event of confirmation of oil on
hydraulic ram cylinder bodies ascertain origin of leak. Inspect hydraulic seals when ram
cylinders are completely extended. Minimum leaks are permissible with symptoms of
"sweating", however in the event of noticing leaks in the form of "droplets" stop using the
spreader until faults are remedied.
