Rauch MDS 8.2 - Hydraulics System; Maintenance and Service

• When selecting the fertilizer, inform yourself of its effects on humans, the environment and the
machine.
• Always follow the instructions of the fertilizer manufacturer.
3.7 Hydraulics system
The hydraulic system is under high pressure.
Fluid escaping under high pressure may cause serious injury and environmental damage. The
following instructions must be observed to prevent danger:
• Always operate the machine below the permissible maximum operating pressure.
• Release the pressure from the hydraulic system before carrying out any maintenance. Switch off
the engine of the tractor. Secure it against reactivation.
• When searching for leaks, always wear safety glasses and safety gloves.
• In case of injury in connection with hydraulic oil, consult a physician immediately as severe
infections may occur.
• When connecting the hydraulic hoses to the tractor, ensure that the hydraulic system is
depressurized, both on the tractor and the machine side.
• Attach the hydraulic hoses of the tractor and the spreader hydraulic systems only with the
prescribed connections.
• Prevent any contamination of the hydraulic circuit. Always suspend the couplings in the brackets
provided. Use the dust caps. Clean the connections before coupling them.
• Regularly check the hydraulic components and hydraulic hose lines for mechanical defects, e.g.,
cuts and abrasions, contusions, bends, tears, porosity, etc.
• Even when stored correctly and used within approved load limits, hoses and hose couplings are
subject to a natural aging process. This limits their storage and service life.
The hydraulic hoses are designed for a maximum service life of 6 years, including storage for a
maximum of 2 years.
The month and year of manufacture of the hydraulic hoses is stamped on the hose fitting.
• Have the hydraulic hoses replaced if they are damaged and after the specified service life has
been reached.
• Replacement hydraulic hoses must meet the technical requirements of the equipment
manufacturer. Make sure the replacement hydraulic hoses meet the maximum pressure
specifications.
3.8 Maintenance and service
Maintenance and service involve additional hazards that do not occur during operation of the machine.
For this reason, take particular care when carrying out maintenance and service work. Work
particularly thoroughly and cautiously.
