URRACO 75 D ERVICE GUIDELINES 1.7.-6 Inspecting / Changing the Hydraulic Oil Filters A suction/return filter and a suction filter are installed in the shredder. The filter cartridges have to be replaced when the <Oil filter> indicator light lights up or at least every 500 operating hours.
URRACO 75 D ERVICE GUIDELINES Suction filter To replace the suction filter, proceed as follows: 1. Have the new filter(s) to hand. Filter cartridge type: see Appendix "Modules and spare parts". 2. Unscrew the old filters from the filter head.
URRACO 75 D ERVICE GUIDELINES 1.7.-8 Checking the Hydraulic Oil Level / Changing the Hydraulic Oil Maximum oil filling is only permissible with retracted hydraulic cylinders. Checking the oil level If the oil drops below the minimum level, the <Hydraulic oil level> indicator light lights up on the control panel.
Page 21
URRACO 75 D ERVICE GUIDELINES Changing the hydraulic oil Change the oil while the plant is at operating temperature (not later than 15 minutes after switching off the shredder). The hydraulic filter should be replaced when changing the hydraulic oil.
Page 22
URRACO 75 D ERVICE GUIDELINES Pump new oil into the hydraulic circuit using the hand-operated pump until hydraulic oil comes out of the measuring connection opening on the oil cooler and of the suction/return filter vent valve. Screw the measuring connection to the oil cooler and close the vent valve on the suction/return filter.
URRACO 75 D ERVICE GUIDELINES Never fill the hydraulic system directly via the cap of the hydraulic tank. Always use the upper hydraulic pipe for this purpose. Filling via the tank allows air to enter the hydraulic system which will cause damage to the components.
URRACO 75 D ERVICE GUIDELINES Oil drain plug Sight glass 1.7.-10 Checking / Changing Engine Oil and Filter Change the oil while the plant is at operating temperature (not later than 15 minutes after switching the shredder off ) Checking the engine oil level and changing the engine oil and the engine oil filter is to be performed in accordance with the drive engine operating and maintenance manual (enclosed separately).
URRACO 75 D ERVICE GUIDELINES 1.7.-11 Checking the Coolant Level / Changing the Coolant Only check the coolant level with the engine switched off and when engine and cooler are cold. At operating temperature, the coolant is hot and under pressure.
URRACO 75 D ERVICE GUIDELINES For draining the coolant, use the drain plug on the right hand engine side of the shredder. The coolant is pumped out by means of the hand-operated pump. Proceed as follows: Remove the protective cap form the drain socket.

URRACO 75 D ERVICE GUIDELINES 1.7.-13 Maintaining the Water Sprinkler Filter (Option) A water sprinkler is installed in the shredder to bind the dust produced during shredding. The water filter is equipped with a pipe connection. The water jet pressure can be set using the hand wheel for setting the holding pressure. We recommend a pressure of between 2 and 3 bar for optimal sprinkling of the material to be shredded.
Page 29
URRACO 75 D ERVICE GUIDELINES Cleaning the water filter: The water filter sieve is to be cleaned by backwashing. It should be cleaned every two months (or at shorter intervals in case of heavy soiling). Procedure: 1. For backwashing, turn the rotating basket fully to the left.
URRACO 75 D ERVICE GUIDELINES 1.7.-14 Adjusting the Belt Tensioning and Alignment Do not tension or align the discharge conveyor belt unless it is switched off. Any adjustment work performed while the conveyor belt is running involves danger of death! Wear work gloves when carrying out repair work to reduce the risk of injuries.
Page 31
URRACO 75 D ERVICE GUIDELINES For tensioning, use the tensioning bolts located in the upper part of the conveyor belt. The conveyor belt must neither be too tight nor too loose. Please ensure that the axles of the belt are always running parallel, i.e. the...
Page 32
URRACO 75 D ERVICE GUIDELINES Adjusting the belt alignment The belt alignment is adjusted using the set screw on the return strand roller above the bending point. Before adjusting the belt alignment, check the belt tensioning and make sure that the axes of the drive roller, the bending points and the deflection roller are in parallel.
URRACO 75 D ERVICE GUIDELINES 1.7.-15 Assembly and Disassembly of the Discharge Conveyor Belt Rollers Wear work gloves when carrying out repair work to reduce the risk of injuries. Only use suitable and approved hoisting gear. Disassemble the discharge conveyor belt drive roller in the following order: Drive belt into lowest position.

URRACO 75 D ERVICE GUIDELINES 1.7.-17 Dismounting the Overbelt Magnet (Option) When you remove the overbelt magnet from the shredder, you have to fold out the discharge conveyor belt and proceed as follows: Discharge conveyor belt into lowest position. Remove hoses from the quick release. Attention, note the position of the hoses for re- installation of the hoses.
URRACO 75 D ERVICE GUIDELINES The hydraulic hoses must be free of pressure. Accordingly, the shredder has to be switched off before dismounting the overbelt magnet and be secured against restarting. Always proceed with utmost care when dismounting the hydraulic hoses due to high hydraulic oil temperatures.
Page 38
URRACO 75 D ERVICE GUIDELINES Procedure: Activity Result Notes Knife is broken off. Switch the shredder off and secure it against accidental restarting. Observe occupational health and safety regulations (protective goggles). No combustible material in the working area! Remove the shredding tools.
